Powerbox Reveals Its High Reliability Power Solution for Subsea Applications
Posted: 2017-6-16

Powerbox, one of Europe’s largest power supply companies and a leading force for four decades in optimizing power solutions for demanding applications, has announced a new technology platform to power industrial applications requiring high reliability and resilience in extreme environments. Designed to power subsea equipment such as gas and oil monitoring and control systems situated on the seafloor, fed from an AC or DC high voltage line feeder the PRBX VB410-380 power solution delivers 48V DC with very high reliability and resilience. The unit comprises a pre-stage converter and a secondary stage with redundant power modules and for monitoring and control, a full set of communications and interfaces.

Industrial applications such as gas and oil situated on the seafloor, or long distance transmission cables require very specific power solutions to supply a subset of electronic equipment operating 24/7 with no downtime, and where maintenance is either very expensive or simply not an option. These applications are usually powered from the shore or from a technical platform generator via a high voltage line, which depending on the power station could be AC or DC voltage within the range of 300 to 900VAC, or 400 to 1500VDC, ultimately requiring a 48V DC intermediate bus voltage to power electronic equipment.  Outputs need to be able to operate in parallel in order to increase the power or to offer redundancy.

Equipment deployed in extreme environments such as the seafloor must be designed for very high reliability and resilience and able to operate within a temperature range of -25 to +80 degrees C without derating, using conduction cooling only. Subsea electronic equipment is often contained within a very tight tubular container fixed to the cable. Powerbox’s PRBX VB410-380 is designed to guarantee the maximum level of isolation between the high-voltage input and the low-voltage output, but with sufficient physical isolation between the different components to allow for tight integration.

“Delivering power to extreme applications such as subsea ones is always a challenge for designers. But in developing standardized, easily reusable sub-systems such as the VB410-380 we have shortened the design cycle and time-to-market for our customers” said Patrick Le Fèvre, Powerbox’s Chief Marketing and Communication Officer. “Expanding sales opportunities, its design philosophy makes it eminently suitable for other applications such as the chemical industry and in highly restricted areas where human intervention is both complicated and risky.”

Using an advanced switching topology the complete system (high voltage input to low voltage output) energy efficiency is over 85%, which compared to earlier generation, similar products is some 10% higher. The PRBX VB410-380 layout is designed and optimized to conduct heat from the dissipative elements to the cold plate, reducing the possibility of internal hot spots and contributing to higher reliability.

The VB410 primary module converts the line voltage to an internal voltage of 380VDC. It includes an active Power Factor Corrector (PFC) and an RS-232 communication bus for the network manager to supervise the power unit. The module is designed with an ‘inrush current free topology’, cleverly reducing peaks on the main line and reducing component stress.

The secondary stage of the PRBX VB380 includes four independent output modules each delivering 95W (48V / 2A). Each output has its own current limiting capability, and an integrated digital controller, used to monitor voltage and current that is readable through a CAN-Bus. Each output can be ON/OFF controlled or made redundant. The CAN-Bus is also used for diagnostic and predictive actions (e.g. to shutdown modules when not required or enable in order to maintain peak power).

Designed to meet specific systems’ requirements, Powerbox’s PRBX VB410-380 complies with all safety, EMI and other regulations relevant to the system.

Cornell Dubilier Introduces New Type HHT Ruggedized Axial Leaded Aluminum Electrolytic Capacitor
Posted: 2017-6-16

Cornell Dubilier Electronics, Inc. (CDE) has announced a new line of axial-lead aluminum electrolytic capacitors, for applications demanding very high-performance under all operating conditions.  The HHT is the only axial-lead electrolytic featuring a glass-to-metal seal to prevent dry-out of the capacitor electrolyte.  Shelf life is an extraordinary10 years and operational rated life is 2,000 hours at rated voltage and +175 °C.  At 150 °C and full-rated voltage, HHT capacitors outperform competitive technologies in a 5,000 hr test with ripple currents of up to 10 Arms.  This level of performance makes the HHT an excellent match for high-stress applications in military, aerospace, down-hole and off-road transportation applications.  Nine values are offered, from 470 µF to 4,700 µF, with ratings from 16 Vdc to 40 Vdc.

The CDE HHT Series is the only aluminum electrolytic capacitor available in the market with +175 °C performance.  This is usually the domain of the considerably more expensive wet tantalum technology.     The HHT’s glass-to-metal seal is the reason.   Without the seal, high temperatures will cause conventional electrolytics to lose electrolyte over time.  This causes a drop in capacitance and an increase in ESR.   With capacitance stability at high temperature, low leakage current and very competitive ESR and ripple current specifications, these devices provide new options for mission-critical applications.   Like other CDE capacitors, the HHT Series is subject to the industry’s most rigorous dynamic testing.  The 20g vibration testing follows procedures outlined in MIL-STD-202, method 204.

Since its founding in 1909, CDE has been dedicated to advancing capacitor technology for new applications. The company combines innovative products with engineering expertise to provide reliable component solutions for inverters, wind and solar power, electric vehicles, power supplies, motor drives, HVAC, motors, welding, aerospace, telecom, medical equipment and UPS systems.

Powerbox’s encapsulated power supply is ready for industrial system integration
Posted: 2017-5-5

Powerbox, one of Europe’s largest power supply companies and a leading force for four decades in optimizing power solutions for demanding applications, has introduced a 100W encapsulated AC/DC power supply, ready for industrial systems integration. Aimed at compact industrial systems applications with limited space, the ENI100 has a narrow width of 31.7mm and a length of 140mm making it easy to fit in even the smallest of places. The unit’s input voltage range is from 90 to 264VAC and the output delivers a fixed 24V at 4A. Based on Powerbox’s flyback topology and proprietary ‘Always On’ regulation mode, the power supply intelligently ‘self-controls’ its output behavior to guarantee continuous operation and quick recovery in the case of a load or temperature fault. The ENI100 is CB certificated according to EN60950-1.

Industrial systems integrators often require small, compact power supplies able to operate in very specific environments such as high electrical fields with the threat of arcing, and that are simple to install, delivering a local safety voltage of 24VDC to the electronic equipment. In such conditions, no exposed metal parts are allowed, resulting in a plastic case with crimped terminals without a physical connection between the internal heatsink and the host equipment chassis. To optimize cooling the ENI100 includes an internal heatsink that distributes the heat to minimize hot spots, simultaneously maximizing the area of contact with the plastic case.

Powerbox’s type ENI100-5138 power supply has a nominal input of 100 to 240VAC although it can be operated with a small derating between 90 and 264VAC. The output voltage is factory adjusted to 24VDC and delivers an output current of 4A. The output is protected against over-current and short-circuit damage by a current limitation operating in ‘Always On’ mode, guaranteeing that the unit will always return to full operation after the output fault is removed. Powerbox’s ‘Always On’ technology also adjusts the available output power while taking cognizance of the unit’s internal temperature in order to keep it in a safe operating zone.
“Industrial system integration often requires compact power supplies that are ready to use, with a footprint as small as possible.” says Martin Fredmark, Powerbox’s VP Product Management. “The ENI100 is mechanically designed to optimize space and to guarantee safe operation in high electrical field applications.”

With safety in mind, the ENI100 has a leakage current less than 100 µA, which for an industrial product is very low and complies with a level of isolation Class I (double isolation between the input and output). The ENI100 fulfills safety standards IEC 60950-1 and is designed to meet UL508. The unit is CB certified according to IEC 60950-1 and complies with related EMC standards and class B. Able to be installed outdoors or exposed to a humid atmosphere (5 to 95% non-condensing) the ENI100 is designed to meet an ingress protection level of 54 (IP54). Input and output cables are fixed to the unit with crimped terminals for easy connection. The product is RoHS II and REACH compliant.

ON Semiconductor Unveils High Performance 5.1 Megapixel Imaging Solution for High-End Security Camera Applications
Posted: 2017-5-5
High resolution AR0521 delivers high frame rate and improved low-light sensitivity with high dynamic range

ON Semiconductor, driving energy efficient innovations, has unveiled AR0521 CMOS image sensor - the first imaging product based on a 2.2 micrometer (µm) Back Side Illuminated (BSI) pixel technology platform targeted specifically at security and surveillance applications.

The AR0521 is a small optical format 1/2.5-inch (7.13mm), 5 megapixel (MP) digital image sensor with an active pixel array of 2592 (H) x 1944 (V). It captures images in either linear or high dynamic range (HDR) modes with rolling-shutter readout, and includes sophisticated camera functions such as binning, windowing, and both video and single frame modes.

The advanced imaging solution offers 8, 10 or 12-bit outputs and boasts excellent video performance at 5MP 60 frames per second (fps) with a 1440p mode for 16:9 video. The superior low-light performance - often an important requirement in security camera applications - is largely due to the larger 2.2 µm BSI pixel that offers higher linear full well and lower noise than a smaller pixel.

Incorporating both an electronic rolling shutter and global reset release, the AR0521 also offers advanced line synchronization controls for multi-camera (stereo) support. The ability of the AR0521 to produce extraordinarily clear and sharp images is enhanced by sophisticated digital processing functions, including integrated color and lens shading correction, digital gain and dynamic defect correction.

Primarily aimed at remote video surveillance applications, the AR0521 consumes very little power even when operating at full resolution of 60 fps at 10-bit output. The operating temperature range of -30°C to +85°C ambient allows the device to be used successfully outdoors in harsh environments.

"The ability to deliver high resolution, high quality video feeds in low-light conditions is becoming increasingly important in many applications," said Gianluca Colli, Vice President and General Manager of Consumer Solutions Division, Image Sensor Group at ON Semiconductor. "This new device pushes the performance boundaries and will enable the development of enhanced indoor and outdoor security systems. Particularly key to its success will be the higher resolution that does not impact low light performance and the ability to generate high dynamic range output at frame rates of 30 fps."

As a result of the programmable optical format (4:3, 16:9 & 1:1) the AR0521 is suitable for multiple use cases in mid- to high-end security applications, including panoramic security cameras, birdseye security cameras, long range security cameras and speed dome security cameras.

Powerbox’s rugged power modules are perfect for harsh environments in extreme industrial automotive applications
Posted: 2017-4-22

Powerbox, one of Europe’s largest power supply companies and a leading force for four decades in optimizing power solutions for demanding applications, has introduced a 400W DC/DC converter for use in industrial automotive applications in extreme environments. Designed for free air convection cooling, the ENA400-M is packaged in an aluminum enclosure with built in heatsink and potted with heat conductive polyurethane to improving thermal dissipation. Ratified for IP67 operation and with a power efficiency of 95%, the DC/DC converter can be operated in ambient temperatures from -40 to +50 degrees C using free air convection. Suitable for 24V and 48V industrial bus voltages, the converter meets ISO7637-2 and EN12895. The ENA400-M’s high efficiency and highly optimized thermal design contribute to an increased lifetime in harsh environments.

Industrial automotive applications such as vehicles in the mining, timber and construction industries, agricultural machinery, trucks, and general outdoor infrastructures require extremely robust DC/DC power supplies that are able to operate flawlessly in humid and dusty conditions with high levels of vibration and often with little or no ventilation. Such conditions require power supplies to include state of the art power switching technology to reduce power dissipation, and thorough mechanical and thermal designs to ensure long life times in such demanding conditions and applications.

“Industrial automotive manufacturers require energy efficient power supplies that are able to guarantee full operation in harsh environments yet are easy to use” says Martin Fredmark, Powerbox’s VP Product Management. “The ENA400-M series is part of PRBX’s ‘one package to fit all’ program developed with our customers that simplifies inventory management and reducing Time-to-Market.”

Built on planar technology with thermal-drains and low ESR MOSFET technology, the ENA400-M has a typical power efficiency of 95%. By the use of a manufacturing practice known as ‘back-flip assembling’, the dissipated power is directly conducted from the components to the top of the case, thus increasing cooling capacity.

Powerbox’s ENA400-M DC/DC converter series has a galvanic isolation level of 500VDC input to output, and input/output to case. All products meet the immunity standard EN61000 (relevant chapters), the EN55022B (conducted and radiated) and a surge test level of 2kV.

Industrial automotive applications are often exposed to water, diesel fumes or dirt, and it is very important that the DC/DC converter cannot be adversely affected by such an aggressive environment. To prevent against any risk of corrosion or water penetration, the aluminum case is protected by a coating layer and encapsulated with a polyurethane resin guaranteeing the product complies with the Ingress Protection rating of 67 (IP67 – Protected from dust and against the effects of immersion in water to depth between 15 cm and 1 meter). The product can sustain 100% relative humidity – non-condensing.
To combat high levels of vibration that it may encounter in harsh environment conditions, the ENA400-M is tested to meet the profile of 5–50 HZ with an acceleration of +/-7.35m/s2 per axis.
 

Ericsson’s pioneering PKB4413DA advanced bus converter delivers industry-leading efficiency
Posted: 2017-4-22
  • The new PKB4413DA advanced bus converter gives power system designers industry-leading 408W and 34A output with inputs from 36-75V, thanks to Ericsson’s sophisticated Hybrid Regulated Ratio (HRR) topology
  • Ideal for high-power, high-performance applications, the module cuts cooling and energy costs by delivering industry-leading efficiency of up to 96% at 12V output
  • The converter’s outstanding thermal derating makes it perfect for environments where airflow is limited or ambient temperatures are high
  • The high-performance DC/DC converter is ideal for intermediate bus conversion applications in networking and telecoms, thanks to its tightly regulated power delivery

Ericsson’s newly launched PKB4413DA is a low-profile, 408W DC/DC converter module, designed to provide point-of-load (POL) DC/DC converters with tightly regulated 12V output at up to 34A. The module’s five-pin, 1/8-brick footprint is compatible with the Distributed-power Open Standards Alliance’s (DOSA) standard and has a full 36-75V telecom input range. This combination makes it ideal for intermediate bus conversion in information and communication technologies (ICT) applications.

Designers who choose the PKB4413DA will benefit from Ericsson’s pioneering Hybrid Regulated Ratio (HRR) technology, which minimises power losses while delivering high-power conversion from a wide range of input voltages. The module offers class-leading performance in thermally challenging situations. Efficiency can be up to 96% with a 48V input and 12V output at half-load. This means the PKB4413DA cuts energy and cooling costs considerably.

Ericsson’s module meets the deployment requirements for intermediate bus voltage and distributed power architectures, and is primarily aimed at high-performance, high-power use cases in industrial, networking, telecoms, servers and data storage equipment.

The HRR topology, found in the PKB4413DA, was first used in Ericsson’s premier quarter-brick PKM-NH family. Because the PKB4413DA responds well to load and line transients, this guarantees that output voltage remains stable, and won’t be affected by the voltage deviations that occur as a result of system bus power disturbances. For power system architects, this ensures intermediate bus voltage integrity remains within the required tolerance.

Thanks to its outstanding thermal performance, even in challenging conditions, the PKB4413DA reliably delivers higher usable power in environments with limited airflow or high ambient temperatures. Its tellurium copper pins give excellent thermal transport, while the module is connected to a coldplate or heatsink via a baseplate. The thermal path from the thermally critical components to the baseplate has been carefully designed, resulting in a flat thermal profile for the key elements, along with excellent heat transfer to the heatsink or baseplate.

Martin Hägerdal, Head of Ericsson Power Modules, said: “The 408W PKB4413DA delivers industry-leading efficiency and output power in an advanced intermediate bus converter. It’s ideal for customers who require an input range between 36V and 75V for high-power industrial, telecoms and networking uses.

“Using Ericsson’s HRR topology, the module delivers a blend of tightly regulated voltage capabilities, best-in-class thermal handling, high efficiency and high current and power handling.”

Powerbox reveals breakthrough coreless power conversion technology for high magnetic field applications
Posted: 2017-1-26

Powerbox, one of Europe’s largest power supply companies and a leading force for four decades in optimizing power solutions for demanding applications, has announced the release of its new coreless technology platform to power medical and industrial equipment operating in very high magnetic field environments such as magnetic resonance imaging or particle accelerators. Using the latest technology in high-frequency switching topologies and digital control with proprietary firmware to optimize efficiency and voltage regulation, Powerbox’s GB350 buck-converter module is the first building block in its category that is able to operate safely when exposed to high radiation magnetic fields of 2 to 4 Tesla. GB350 delivers an output power of 350W and when higher power levels are required it can be paralleled using an interleaving mode thus reducing EMI.

Medical and industrial applications such as magnetic resonance imaging (MRI) and particle accelerators (PA) generate high magnetic fields to induce the RF energy required to activate the hydrogen nuclei in the case of imaging, or to accelerate particles in research and industrial equipment.

Modern MRI systems usually generate 1.5 to 4 Tesla, making conventional power supplies using ferrite material useless due to inductance saturation as a result of the MRI magnet disturbing the energy transfer. To prevent parasitic saturation, power supplies are traditionally positioned outside the shielded operation room.  Installing the power supplies remotely requires long cables with subsequent power losses, and it is also a big challenge to power the latest generation of measuring equipment that require stable and tightly regulated voltages under fast transient load conditions.

To reduce energy consumption and to guarantee the level of quality required by integrated equipment, systems manufacturers are now integrating local power supplies near to the load.  However, placing equipment directly in the radiated magnetic field requires an innovative power solution known as ‘coreless power units’ and a state of the art switching power stage.

Designed to respond to this demand and to guarantee the highest efficiency and tightly regulated output voltage at any load-condition, Powerbox’s GB350 coreless power unit is fully controlled by a digital processor that manages the complete power unit from switching parameters (e.g. dead-time and duty-cycle optimization) to output voltage characterization. To guarantee a high level of flexibility and the possibility to re-profile the power unit characteristics when equipment manufacturers upgrade new hardware or implement a software revision, the GB350 micro-controller can be programed with optimized configuration files downloaded through the digital interface.

“Combining the latest technology in digital power and very advanced coreless energy transfer, the GB350 is an important component of the Powerbox Custom Power Solution toolbox,” said Tomas Isaksson, Chief Technology Officer at Powerbox. “With more than 3,500 Custom Power projects delivered to market, it is very important to rely on a strong platform portfolio, reducing time to market in demanding applications such as medical magnetic resonance imaging.”

As part of Powerbox’s Custom Power Solution Toolbox, the GB350 and products based on that technology are tested, verified and qualified in accordance to end customers’ specifications.

Highly Integrated Capacitive-Digital Converter Delivers Superior Gesture Sensing and Enhanced Touch Performance to Automotive and Industrial Systems
Posted: 2017-1-18
Eight-channel device exhibits sensitivity up to 150 mm away to support gesture recognition

ON Semiconductor, driving energy efficient innovations, has introduced a new touch/proximity sensing solution that combines industry-leading performance, cost-effectiveness and convenience in a single chip. The LC717A30UJ high dynamic range capacitance-to-digital converter uses mutual capacitance to detect changes in capacitance down to femtofarad (fF) levels. Parasitic capacitance cancellation raises the detector sensitivity, while its built-in noise rejection mechanism combats the effects of electromagnetic interference (EMI).

The eight capacitance-sensing input channels make the LC717A30UJ highly optimized for use in systems where an array of switches is required. The device includes an integrated multiplexer for input channel selection, analog-to-digital converter, dual-stage amplifier that determines capacitance changes plus outputs analog amplitude values, system clock, power-on reset circuit, and all the necessary control logic to create a total solution. Both I2C and SPI interfaces are selectable based on the system application needs.

As the device's sensitivity has a range of 150 millimeters (mm) - beyond the scope of any competing device on the market - its higher sensitivity enables gesture motions as well as offering conventional touch functionality, thereby enhancing users' control options to address a wide range of application scenarios. In addition, it is capable of operating with an airgap between the sensor/PCB and the protective cover - so engineers can eliminate the inclusion of a light guide from the assembly and reduce overall complexity. This device also includes an integrated automatic calibration function which optimizes and self-calibrates total capacitance according to electrode, line capacitance, and surrounding environment, thus significantly accelerating system development cycle time as well as robustness in the field.

The LC717A30UJ delivers rapid responsiveness, with a measurement time of 16 milliseconds (ms) for its 8 sensing channels and runs off a +2.6 volt (V) to +5.5 V supply with a low-power standby mode of one microampere (µA). The high degree of integration means that minimal external components are required, thereby further reducing the bill of materials. To support the needs of automotive applications such as vehicle entry systems and dashboard controls, the device is AEC-Q100 compliant. With its high integration level and wide dynamic range, it can also be employed in a range of touch or gesture human interfaces in industrial and consumer end products such as induction cookers, refrigerators, home entertainment systems, building automation equipment, industrial equipment, and lighting controls.

"As we all know, touch technology has witnessed widespread uptake within the consumer electronics sector over the course of the last decade. Now there are an ever-increasing number of opportunities for its utilization in various nonconsumer sectors," said Ikuya Kawasaki, General Manager of the Intelligent Power Solutions Group at ON Semiconductor. "This new device possesses the key attributes needed to address these demands, by providing a robust, simple to deploy solution that successfully combines low price and superior performance."

  • PKB4413D offers up to 96% efficiency at 12V output, significantly reducing energy and cooling costs
  • Advanced design offers excellent thermal derating, making it ideal for use in environments with high ambient temperatures or limited airflow
  • High-performance DC/DC converter delivers tightly regulated power for intermediate bus conversion applications in telecom and networking markets

Ericsson has launched a low-profile, 450W DC/DC converter module that is designed to deliver a tightly regulated 12V output voltage at up to 37.5A to point-of-load (POL) DC/DC converters. Offered in a 5-pin 1/8-brick footprint, compatible with the DOSA (Distributed-power Open Standards Alliance) standard, the new PKB4413D advanced bus converter has an input range from 36V to 60V and is ideal for intermediate bus conversion in ICT (Information and Communication Technologies) applications.

The PKB4413D incorporates the company’s cutting-edge HRR (Hybrid Regulated Ratio) technology to deliver high-power conversion from a wide input voltage range, while keeping power losses low. Offering class-leading performance in thermally challenging environments and delivering a typical efficiency of 96%, with a 48V input and 12V output at half-load, the module significantly reduces energy and cooling costs. Competitive products typically dissipate 18% or more of their input power at 30A loads.

Meeting the deployment requirements for distributed power and intermediate bus voltage architectures, the module particularly targets high-power and high-performance use in networking and telecommunications equipment, servers and data storage applications, as well as industrial equipment.

Ericsson has leveraged its highly innovative HRR topology in the development of the PKB4413D. Initially introduced in the company’s high-end quarter-brick PKM-NH family, the technology has been further enhanced to deliver even better utilization of the powertrain. The module’s excellent response to line and load transients guarantees the output voltage will remain stable and immune from voltage deviations that are due to power disturbances on the system bus. This retains intermediate bus voltage integrity within the tolerance band required by power system architects.

Delivering excellent thermal performance in challenging circumstances, the converter provides higher useable power in high ambient temperatures or limited-airflow environments leading to higher reliability. The use of tellurium copper pins provides excellent thermal transport, and a baseplate connects the module to a heatsink or coldplate as standard. In addition, careful attention was given to the design of the thermal path from the thermally critical components to the baseplate. This has resulted in a flat thermal profile for the critical components and outstanding heat transfer to the baseplate or heatsink.

“Targeting customers looking for high power capabilities in telecom, networking and industrial applications, the new 450W PKB4413D is the second in a new series of high-power advanced intermediate bus converters,” said Martin Hägerdal, Head of Ericsson Power Modules. “The module builds upon the company’s HRR topology to offer high power and current handling, together with high efficiency, tightly regulated voltage capabilities and best-in-class thermal handling.”

The PKB4413D has been designed and manufactured by Ericsson to meet the highest standards available for DC/DC power converters in the industry, delivering the levels of quality and confidence that are required by power system designers to develop long-term and high-performance platforms.

Posted: 2016-11-2

Cornell Dubilier Electronics, Inc. (CDE) has introduced the latest in its series of Flatpack ruggedized flat aluminum electrolytic capacitor, the MLSG.  This series targets compact power supply applications in military and aerospace, as well as other critical systems.  Design enhancements and a new electrolyte push the MLSG to nearly double the operating life of its predecessor, at no added cost.  Two principal package profiles are offered in this technology, the MLSG Flatpack which measures just 0.5” thick and 1.75” wide and the MLSG Slimpack measuring 0.5” thick by 1.00” wide, both offered in length increments of, 1.5”, 2.0”, 2.5” or 3.0”.

MLSG Flatpack capacitors can be made to withstand up to 50g vibrations (10g standard) and altitudes greater than 80,000 feet.  With stainless steel cases and near hermetic welded seals, they are built for extended duty in very harsh conditions.  Especially noteworthy is that a high level of performance is maintained over the full operating temperature range.  Capacitance retention at -55 °C is very strong, with excellent high temperature performance up to +125 °C.   The new electrolyte system is fully REACH compliant, allowing application of the components in a broad range of applications where space efficiency and extraordinarily long life are required.

A wide range of standard capacitance values from 220 µF to 24,000 µF are available, with voltage ratings up to 250 Vdc.   The unique flat package design does more than save space.  It is easily cooled, and can offer unique flexibility in ganging two or more devices in ways that conventional electrolytics can’t. 
Options include High Vibration (HV), for performance to 50g and High Reliability (HR), with burn-in at rated voltage and 85 °C.  Where a true glass-to-metal hermetic seal is required, CDE offers the MLSH Slimpack, which is similarly constructed in a flat stainless steel package.  It is available in nine values, from 120 µF to 3,200 µF, with ratings up to 250 Vdc.

“The latest MLSG Flatpack capacitors are purpose-built for their mission,” said Mike McGeachie, design and application engineer. “They provide a very high level of electrical and environmental performance.  Engineers don’t usually have such an option when selecting passives.”

Wolfspeed Delivers Industry’s First 1000V SiC MOSFET
Posted: 2016-10-6
Meets growing demand for efficient electric vehicle fast battery chargers

Wolfspeed, a Cree Company and a leader in silicon carbide (SiC) power products, has introduced a 1000V MOSFET that enables a reduction in overall system cost, while improving system efficiency and decreasing system-size. The new MOSFET, specially optimized for fast charging and industrial power supplies, enables a 30 percent reduction in component-count while achieving more than 3x increase in power density and a 33 percent increase in output power.

“Supporting the widespread implementation of off-board charging stations, Wolfspeed’s technology enables smaller, more efficient charging systems that provide higher power charging at lower overall cost. This market requires high efficiency and wide output voltage range to address the various electric vehicle battery voltages being introduced by automotive suppliers,” explained John Palmour, CTO of Wolfspeed.

“Wolfspeed’s new 1000V SiC MOSFET offers system designers ultra-fast switching speeds with a fraction of a silicon MOSFET’s switching losses. The figure-of-merit delivered by this device is beyond the reach of any competing silicon-based MOSFET,” Palmour added.

With the introduction of its 1000V SiC MOSFET, Wolfspeed leads the market with the industry’s most complete device portfolio. Wolfspeed was the first company to release a commercially qualified SiC MOSFET in 2011 and remains a leader today, committed to delivering great technology and value.

Designers can reduce component-count by moving from silicon-based, three-level topologies to simpler two-level topologies made possible by the 1000 Vds rating of the SiC MOSFET. The increase in output power in a reduced footprint is realized by the ultra-low output capacitance―as low as 60pF― which significantly lowers switching losses. This device enables operations at higher switching frequencies, which shrinks the size of the resonant tank elements and decreases overall losses, thus reducing heatsink requirements. Wolfspeed has determined these proof-points by constructing a 20kW full-bridge resonant LLC converter and comparing it to a market-leading 15kW silicon system.

New Technology Report Introduced at APEC 2015
Posted: 2015-3-21
Current Development in 3D Packaging With Focus on Embedded Substrate Technologies

At APEC 2015, the PSMA Packaging Committee will introduce the first comprehensive study of the feasibility of using Embedded Substrate Technologies to build power sources. The report entitled “Current Developments in 3D Packaging with Focus on Embedded Substrate Technologies” will also be discussed at the Industry Session on 3D Packaging. The report was prepared under contract by LTEC Corporation with work subcontracted to Anagenesis and Fraunhofer-Institute. The intent of this article is to provide PSMA members a high level preview of the contents of Technical Report.

The PSMA Packaging Committee believes the 340 page report with extensive illustrations of the leading edge product technologies will provide valuable insights to executives and managers in their own analysis of how currently available materials and processes could be best used for the creation of advanced high efficiency, high power-density power electronic products. The report builds upon the findings of the Phase I report - 3D Power Packaging - issued by the Power Sources Manufacturers Association (PSMA) Packaging Committee in 2014.

Background

Let’s begin with a little background. The power electronics industry and the semiconductor industry are inseparably intertwined with one another, and both are facing unprecedented market challenges for efficiency, cost, construction and thermal issues which provide many opportunities for innovation. These industries are in the focal point of the “energy challenge” a multifaceted problem that involves mobile and cloud infrastructure systems, Internet-of-Things, renewable energy, smart grid, vehicle electrification, and across-the-board power efficiency enhancements in order to keep up with the industry's rapid growth in data consumption. These are the competiveness and sustainability challenges of the twenty-first century.

The paradigm shift we have been experiencing in semiconductor packaging technology was brought about by advanced deep submicron semiconductor technology reaching a “cost barrier” that prevented further cost reduction by adding more functions to the semiconductor die. This barrier was circumvented through the development of wafer thinning that enabled through-silicon-via (TSV) technology, and the eventual introduction of 2.5D and 3D integration that facilitated heterogeneous (“More than Moore”) integration. It will allow the power requirements of the digital load to increase 2 to 5 times, within the same footprint, in a single generation. The power sources community must now find ways to package power sources that will meet this demand, but with no increase in footprint.

In parallel, power semiconductor technology has been facing a “construction barrier” that prevents realization of the huge benefits new technology can offer in terms of increased power efficiency and higher power density. These new technologies which include gallium-nitrogen (GaN), silicon-carbon (SiC), and gallium-arsenic (GaAs) power semiconductor devices all require operation in an environment that is free of bond wires and minimizes parasitic interconnect elements. The best possible packaging technology to achieve this is embedding active and passive components in organic or inorganic substrates.

Overview of the Report

The report begins with a discussion of PCB embedding technology, which is fueled by the rapid evolution of low-power embedding and 3D packaging technologies, which are in high volume production. These technologies will in turn enable power electronic systems to deliver higher efficiency and higher power density.

Embedding Actives and Passives in Substrate using Shinko Electrics Molded Core Embedded Package

In addition to substrates the report dedicates entire chapters to each of the passive components (resistors, capacitor, and inductors) as well interposers and additive manufacturing.

Embedding using Formed or Inserted Components
Embedding using Formed or Inserted Components

The report also discusses high temperature die and component attach technologies that are evolving rapidly in the research labs; however, a single, low-cost, “one-size-fits-all applications” high-lead solder-substitution technology is currently unavailable and addresses the fact that high power-density component embedding and 3D packaging of power semiconductor devices also have to overcome a “thermal barrier.” Simply stated, it is more challenging to remove heat generated within the body of a 3D integrated system than from a planar, two-dimensional surface. This leads to a discussion of advanced thermal management technologies which are key enablers for 3D packaging as well as PCB embedding.

The authors acknowledge and devote a chapter to the fact that high power-density component embedding and 3D packaging of power semiconductor devices also have to overcome a “thermal barrier.” Simply stated, it is more challenging to remove heat generated within the body of a 3D integrated system than from a planar, two-dimensional surface. This leads to a discussion of advanced thermal management technologies which are key enablers for 3D packaging as well as PCB embedding.

In addition to their primary research, the team conducted a worldwide literature review and analysis of research and development (R&D) published by participating organizations in the USA, Asia-Pacific Region, and the EU, and identified several potentially high-impact technologies of interest to the power electronics and the semiconductor industries.. In terms of leadership positions, Germany and the EU appear to lead in the area of high-power PCB embedding and research into vertical interconnect/high-lead replacement technology, while Japan is leading in low power, high-density embedding, high performance, low CTE, high modulus (low warpage) substrates, and organic interposer technologies.

Finally the report highlights some of the technology gaps as well as a recognition that this new technology requires updated or additional standards for manufacturing and testing. This report reviews the existing and pending new standards for PCB embedding which the IPC Association has taken the lead to author. However, much additional standard action is needed since the manufacturing supply chain is still evolving. Procedures need to evolve to establish compatibility of up-top metal-die design and PCB layout rules, testing, quality control, and for assigning ownership of failure.

In summary, there has been substantial progress and excellent opportunities lie ahead for the power electronics and semiconductor industries and the entire manufacturing ecosystem to embrace PCB embedding and 3D packaging technologies for power electronic applications. The intersection of these technologies with the emerging wide-bandgap power semiconductor technology creates truly exciting possibilities at the same time the power electronics industry faces unprecedented challenges to help mitigate the fast growing demand for electricity and environmental problems our world faces. Embedded substrate packaging technologies can be, and will be deployed in hybrid and electric vehicles, alternative energy generation and distribution systems, smart grid, industrial, and military aerospace applications in the coming years and beyond. These technologies, combined with wide-bandgap semiconductor devices will literally re-vitalize the entire power electronic infrastructure block by block, module by module, for the twenty-first century.

As a benefit of PSMA membership, the Current Development in 3D Packaging with Focus on Embedded Substrate Technologies report will be sent to all PSMA Regular and Associate member companies and Affiliate companies will be able to purchase the report at a reduced price. The report will also be offered to others in the industry at a price of $2990. You can view the report at the PSMA Exhibit booth at APEC 2015 and shortly the Table of Contents will be available on the PSMA website: www.psma.com.

PSMA Publishes Technology Report: “Current Development in 3D Packaging With Focus on Embedded Substrate Technologies”
Posted: 2015-3-17
Comprehensive report is the first to address “More than Moore” digital power demands by accelerating the development of higher density power sources using new, disruptive packaging technologies

March 16, 2015—The PSMA (Power Sources Manufacturers Association) Packaging Committee announced today that it has published a report titled “Current Developments in 3D Packaging With Focus on Embedded Substrate Technologies.” The first comprehensive study on using embedded substrate technology for building power sources, the report contains extensive research and product illustrations geared to an audience of technology executives and design engineers. Its purpose is to offer an in-depth industry perspective on how currently available materials and processes can be best used for the creation of advanced high-efficiency, high-power-density power products.

The PSMA created the 3D packaging report to address the pressing demands in the power industry to accelerate the development of higher density power sources. The first challenge arose from digital semiconductor packaging technology hitting a “cost barrier” brought about when advanced deep-submicron semiconductor technology could no longer reduce cost with the addition of more functions to the semiconductor die. This barrier was circumvented through the development of wafer thinning that enabled through-silicon-via (TSV) technology and the eventual introduction of 2.5D and 3D integration, which facilitated heterogeneous (“More than Moore”) integration. This integration allowed the power requirements of the digital load to increase two to five times, within the same footprint, in a single generation. Now the power industry is tasked with finding ways news ways to package power sources that will meet this demand, but without increasing footprint.

In parallel, power semiconductor technology is facing a “construction barrier” that prevents the realization of the significant benefits new technology can offer in terms of increased power efficiency and higher power density.  These new technologies, including gallium-nitride (GaN), silicon-carbide (SiC), and gallium-arsenic (GaAs) power semiconductor devices, all require operation in a package that is free of bond wires and that minimizes parasitic interconnect elements. Both of these challenges can be addressed with power packaging utilizing embedded substrate technologies and are addressed in the report.

The PSMA’s 340-page report, prepared under contract by LTEC Corporation with work subcontracted to Anagenesis and Fraunhofer-Institute, is based on the Packaging Committee’s extensive research of over 750 articles and papers, analysis of 450 presentations/papers, and by conducting 30 industry expert interviews. Information was also derived from attendance at 10 industry conferences, workshops and seminars. The report contains 172 links and 394 citations.
The report provides detailed analysis of substrates (organic and inorganic), components (actives and passives), thermal management, high temperature die, packaging technologies, interposers, as well as additive manufacturing and laser fabrication. Each passive component (resistors, capacitors, inductors) has an entire chapter detailing which suppliers are currently shipping products usable in power sources.  Every chapter covers manufacturing issues and includes references to contract manufacturing companies already producing power products utilizing embedded substrate technology. Embedded substrate packaging leverages the large investment made by the digital industry in advanced packaging technologies and is being used to resolve the power source construction challenge. As the report demonstrates, 3D power packaging using embedded substrate technology is a disruptive technology, in that it enables large increases in power density and efficiency.

Co-chairs of the PSMA Packaging Committee, Ernie Parker of Crane Aerospace & Electronics and Brian Narveson of Narveson Consulting, described the report as “the first comprehensive document to discuss the  challenges companies will face to implement embedded substrate 3D power packaging to create the significantly higher power densities driven by the “More than Moore” digital power demands.”

The PSMA report on 3D packaging will be provided free of charge to PSMA Regular and Associate members.  Affiliate members can purchase the report for the reduced price of $190.  Others interested in the report may order a copy from PSMA for $2,990.
