TDK offers a comprehensive calculation and selection tool for film capacitors for PCB mounting

TDK Corporation presents the new, powerful and intuitive CLARA tool (Capacitor Life And Rating Application) for calculating and selecting EPCOS and TDK film capacitors for PCB mounting. The tool offers a versatile parametric search functionality. This includes a search for capacitance, voltage range as well as for rated voltage, RMS and peak current, temperature, maximum dimensions and volume, approvals, reference standards as well as typical applications.

By clicking just once, the performance of up to four capacitors can be simulated under application conditions. This is displayed in a clear table, which may include the following parameters, for example: operating temperature, DC voltage, AC voltage, peak current and expected service life. Furthermore, safety tolerances are specified allowing developers to adjust the configuration in line with their specific requirements. Moreover, a warning is issued if the permitted capacitor parameters are exceeded.

Application conditions, including personal notes, can be stored for future use. STEP files and SPICE simulation data are available for the majority of capacitors. CLARA is linked to the TDK Product Center. The selected capacitors can be easily ordered from there by means of service distributors. The new tool is available for developers at:

White Paper: Energy Harvesting for a Green Internet of Things

The Energy Harvesting White Paper Committee is preparing a White Paper on Energy Harvesting elucidating the enormous opportunities of the technology despite a reluctant adoption in some industries.

Although Energy Harvesting methods and devices have reached a credible state-of-art, relatively few devices are currently commercially available and off-the-shelf harvester solutions often require an extensive adaption to the envisaged application. A synopsis of typical energy sources, state-of-the-art materials and transducer technologies for efficient energy conversion, storage and management encompasses a wide range of successful research results. But developing power supplies for actual applications reveals their strong dependence on application-specific installation requirements, power demands and environmental conditions resulting in a less extensive portfolio of successful system integrations.

The industrial challenges for a massive spread of autonomous sensor systems are manifold and diverse. Reliability issues, obsolescence management and supply chains need to be analysed for commercial use in critical applications. On this front, the gap between currently available solutions and use-case scenarios is analysed from the perspective of the user. The white paper then proceeds to identify the key advantages of energy autonomy in environmental, reliability, sustainability and financial terms.

Energy harvesting could lead to a lower CO2 footprint of future IoT devices by adopting environmentally friendly materials and reducing cabling as well as battery replacement. Further research and development is evidently needed to achieve a technology readiness levels acceptable for the industry. From this discussion, this white paper will propose a future research and innovation strategy for industry-ready green microscale IoT devices, as a key and seminal initiative to provide useful information to the different stakeholders involved, encourage more interaction between them and deliver industry ready solutions.

1991-2000: Reminiscences from an early PSMA Board Member and APEC Publicity Chair

 

The PSMA Strategic Agenda for the 90s included:

  • Fostering communications and cooperation between the various segments of the power sources industry. 
  • Educating manufacturers on improving quality and reliability of their products.
  • Encouraging and promoting industrywide ethical practices, policies and procedures.
  • Continuing to identify and communicate the needs of the user community to the manufacturing community.

As mentioned in my article in the last issue of the Update "In the Beginning", in 1990 PSMA joined IEEE IAS and PELS as a co-sponsor of APEC. I would opine that "1991 was a turning point for PSMA and APEC." 

APEC 91, the first conference sponsored by the 3 organizations, was led, as continues today, by a team of volunteers representing the 3 sponsors, including General Chair Chuck Harm, PELS; Program chair Dr. Tom Jahns, IAS; and Exhibits Chair Dave Kemp, PSMA. The conference was a huge success, though not without its challenges. The Gulf War had an impact with a reduction in our projected international attendance. Our initial concerns were confirmed when David Fields of TDK-Lambda U.K. a Plenary Session speaker, cancelled. His presentation was to address the world market for power supplies. I was asked to take his slot and presented "Global Power Supply Implication...the squeeze is on." I also led an evening rap session titled "Are Power Supply Manufacturers a Band of Liars and Thieves?" During his Keynote Speech, W. J. Warwick, President of AT&T Microelectronics, mentioned the topic of my rap session, saying "he will need to know if it's safe to go back to the office."

Some notable moments from APEC social events in the 1990s:

  • APEC '93 was held in the Town and Country resort in San Diego. The social event was a harbor dinner excursion on the San Diego Bay. They had to add a second ship!
  • APEC '98 was held at the Disneyland hotel where we negotiated for the Adventureland Area to be re-opened for our exclusive use for the Wednesday social event. Yes, Indiana Jones was working that night!
  • APEC '99 was held in Dallas. We tried something new for the social event - a bull was brought up to the Adam's Mark hotel ballroom in a freight elevator. Each of the attendees had a chance to ride him. Note: He was surely drugged, I survived.

One challenge I undertook as APEC Publicity Chair, that did not have much success, was to invite a local VIP to greet us. While most declined due to restrictions and other obligations, many did send nice letters welcoming APEC. Some of these VIPs include Presidents George H. W. Bush and Jimmy Carter; and Governors Mike Foster, Louisiana; George W., Texas; and Arnold Schwarzenegger, California.

On the other hand, I was successful in getting APEC print and broadcast media attention with a few (Micro-) mice running around a maze. The APEC '93 Micro Mouse contest was broadcast on ABC in San Diego.  The San Jose Mercury News had a full color photo of the contest in their Mar 6,1996 edition. And both the Orange County Register and FOX local channel 11 covered our 2004 event in the Disneyland Hotel ballroom. 

APEC 2016 in Long Beach was the last APEC I attended. It was overwhelming to see how much APEC has grown - the program committee had to sort thru 1212 Technical Session Abstracts submitted from 45 different nations. There were an amazing 370 booths in the exhibit hall! I learned a new topic called "Internet of Things." And I can reflect back to 1995 in Dallas where we offered 140 technical papers in 21 sessions with four parallel tracts.

Wishing PSMA much success as you move forward into the future.

TDK offers a comprehensive calculation tool for aluminum electrolytic capacitors

TDK Corporation (TSE:6762) presents the fully revised version 4.0 of the tried and tested Online AlCap Useful Life Calculation Tool for EPCOS aluminum electrolytic capacitors. The tool covers all new high-voltage capacitors (>150 V DC) with screw, snap-in and solder pin connections. These DC link capacitors are particularly suitable for new designs of converters for industrial applications, such as photovoltaics and wind power generation, as well as uninterruptible power supplies.

The AlCap tool enables up to 15 load profiles to be simultaneously entered, calculated and, if so desired, stored for later use. This powerful function allows applications to be developed both with single capacitors and capacitor banks. Furthermore, the tool can perform on a customer-specific basis calculation. This merely requires the CSC code specified in the respective data sheet to be entered.

Once all relevant values have been entered, in addition to the useful life of the capacitors under defined load conditions, the user also obtains data regarding the hot-spot temperature, power dissipation and much more. Coupled with its useful lifecycle under defined load conditions, the AlCap tool provides industrial designers a solution that meets the needs of their demanding applications.

TDK Selection Tool for PTC Inrush Current Limiters

TDK Corporation presents a new, user-friendly tool to help users select the right PTC inrush current limiters (ICL) for a range of different power supply and converter topologies. The intuitive tool is available online and does not need to be downloaded. The selection process is divided into four stages: After specifying the circuit structure and the capacitor bank's total capacitance, the developer must then enter the charging voltage and the maximum ambient temperature of the PTC inrush current limiter. After this has been done, the tool displays a list of suitable components for the user, and if a parallel connection is required, the number of components required is also shown. The most important key figures are also shown, as well as links to service distributors that sell the PTC ICLs.

One significant advantage of PTC inrush current limiters is the fact that they are intrinsically safe. In the event of an internal short circuit in the device when it is switched on, this component quickly limits the current to non-critical levels. Furthermore, this component ensures gentle charging of the DC link capacitors.
 
In addition to their use in converters and power supplies for industrial and household electronics, PTC inrush current limiters are also used in the field of e-mobility – such as in on-board charging circuits and for the charging and discharging of DC link capacitors in hybrid and electric drives.

In the Beginning

Reminiscences from an early PSMA Board Member

WOW!. Happy 35th Anniversary PSMA.

In the 1970s and early 80s the power electronics industry encountered a huge leap in power supply design technology driven in part by the introduction by Apple and IBM of personal computers. Up until that time, the technology primarily used was large and heavy linear technology power conversion, "boat anchors" manufactured in two car garages as the expression went. During that time, the industry also began to face the challenge of transitioning to bi-polar and high frequency MOSFET designs that would create more efficient, smaller, and lighter products. This encouraged a group of design engineers and marketing leaders to explore creating a new industry group to focus on educating themselves and their customers as the industry began to implement and accept these evolving power technologies. At that time Electro, PowerCon and Westcon were the trade shows and conventions focusing on power electronics. 

On Nov 15, 1985, the Power Sources Manufacturers Association, PSMA, was founded as a 501 C (6) nonprofit industry association. Three months later, in Feb of 1986, the first Board of Directors were elected at a meeting held in Dallas, TX. Tim Parrott served as President and Ron Koslow was PSMA's first Chairman. The Bylaws identified three levels of membership – Regular (Manufacturers of power sources and conversion equipment), Associate (Users of power sources and conversion equipment, or manufacturers of components designed for incorporation into power sources and conversion equipment) and Affiliate (Organizations involved in the power industry, including Manufacturer's Representatives, Distributors, Advertising, Marketing, Consulting, Publications).

To establish early credibility, the Board decided to create a "Handbook of Standardized Terminology for the Power Sources Industry". Michael Foldes led the Technical Committee that also included Dan Ketchum, Earl Crandall, Emilie Creagar, Chris DuBiel, Gene Goldberg, Sydele Petch and myself. This was before email and online collaboration tools; Michael sent us each an 8" disc for making our corrections suggestions and additions

To provide industry exposure PSMA co-sponsored the Power Electronics Conference, PEC, in San Jose in Feb of 1989. PSMA Chairman Art Hamill said, "we believe there is a need for an industry-wide forum which brings together the component suppliers, manufacturers and users of power sources and suppliers. That conference and exposition offered six half day Professional Education Seminars and nine Technical Sessions. One year later, in February 1990, PEC was held at the Long Beach California Convention Center and featured three tracks of "Issue Forums" to discuss industry trends.

To create "deliverables" a Research and Development Committee was formed, led by Donald Staffiere of Digital Equipment and John Woodard of ITT Power Systems, with members representing suppliers, users and university members. In 1990, the committee completed its first report to the Association on the status of R&D in the world and presented the results at the PSMA Annual Convention held in Long Beach, CA in conjunction with PEC. This report evolved over time into the current PSMA Power Technology Roadmap.

In March of 1990, John Steel represented PSMA at an IEEE PELS Power Electronics Retreat with leaders from industry and academia. Interestingly, the meeting minutes contained a sidebar that read, "This was the high energy point of the day. Even though we didn't quite know what that meant, we liked the words 'GREEN ENERGY".

Expanding PSMA's exposure, later that year we participated at the Canadian High Technology Show in Toronto. We conducted a Customer-Supplier partnership forum, Norm Berkowitz of Computer Products and myself representing the US, and Glen Belland (Electronic Craftsman) and John Rowbottom (NCR) representing Canada.

After the 1990 PEC and APEC conferences, a group representing PSMA negotiated with representatives of PELS and IAS to become the third financial and technical sponsor of APEC (Applied Power Electronics Conference). The Sponsor Agreement on the Continuing Operation of APEC was written by Bob White and the signers were John M. Steel, PSMA Chairman, Ronald M. Jackson, President IEEE Industrial Applications Society (IAS), and Thomas G. Wilson, President IEEE Power Electronics Society (PELS). In Jan of 1991, Dave Kemp and I were appointed Co-chairs of the APEC Technical Program Committee.

There are so many more names that deserve a shout out in the first five years of PSMA. A partial list of the PSMA family at that time includes: Norm Berkowitz, Mike Brown, Lee Campbell, Frank Cathell, Earl Crandall, Emilie Creagar, Chris DuBiel, Mike Foldes, Paul Fulton, Gene Goldberg, Art Hamill, Albert Himy, Dave Kemp, Dan Ketchum, Jim Kimball, Ron Koslow, John Lombardi, Sr., Doug McIlvoy, Mohan Mankikar, Chuck Mullett, Tim Parrott, Sydele Petch, Stu Roberts, Jeff Shepard, Don Staffiere, John Steel, David Thompson, Dean Venable, Ole Vigerstol, Bob White and John Woodard.

We hope to include another article on the early history of PSMA in a future issue of the UPDATE

PSMA Core Loss Studies

Over the past five years, the PSMA Magnetics Committee has sponsored five Special Projects to better understand the flux propagation in ferrites and the reasons why the performance of large inductor cores performed so poorly compared to the expectations based on published specifications from the suppliers.

The first three projects - PSMA -Dartmouth Core Loss studies- were undertaken by Dartmouth under the leadership of Professor Charles Sullivan and the results are available on the Magnetics Forum on the PSMA web site. Based on some of the insights from these projects formed the basis for the 2 most recent projects – PSMA- SMA Core Loss Studies Phase 1 and Phase 2.

The last two Core Loss Studies are now complete, and this article highlights some of the most interesting findings.  This article is not as comprehensive as the reports, and the reader is encouraged to read the full reports on the PSMA web site for more information.

PSMA–SMA Core Loss Study Collaboration

SMA Magnetics was interested in why large inductor cores performed so poorly compared to expectations based upon published specifications. At the the same time, PSMA was interested in flux propagation in ferrites and why the performance factor B*f was lower and peaked at a lower frequency for larger cores.

Charlie Sullivan (Dartmouth) recognized that there was significant overlap in these interests and arranged an introduction which resulted in the Phase I PSMA-SMA core Loss study. The findings of the Phase I study were so intriguing that a Phase II study followed, which built upon the data from Phase I.

The Phase I and Phase II test reports can be found on the PSMA website Core Loss Studies tab of the Magnetics Forum. The Phase I report is publicly available; Phase II is currently only available to PSMA members, and will be publicly available in late 2021.

PSMA - SMA special project – Phase I

The purpose of the Phase I PSMA-SMA Core Loss projects was to study the flux distribution within ferrite cores while operating.  The concept is that a small area internal to the core can be enclosed by a test winding inserted into drilled holes.  The voltage on the test windings shows the dφ/dt of the flux.

Initially, eight specially machined cores, two each of four materials, were made by Fair-Rite.  Three holes were drilled into each core so that flux in the innermost 1/9th of the core area could be compared to the excitation.  These cores were shipped to SMA for study.

      

Although the original scope was to test these eight cores, SMA drilled seven more 50 mm cores of various materials to provide a larger sample.

A surprising result for some of the cores was that the flux density in the center of the core was much higher than the average flux density, peaking at just over 2.5 times.  Further, it had a large leading phase.

 

PSMA - SMA special project – Phase II
Phase II was a larger study comprising five parts:


1. Large core testing–flux propagation in ferrites

Several large cores were drilled with nine holes so that three sets of wires enclosed progressively smaller internal areas.  In this way, the flux and flux density can be measured in three shells and the center for comparison with the excitation voltage.

 

 

Two other large cores were drilled so that the voltage can be measured around any of 49 segments.  Each segment is the same size, 1/49 of the total, so one-to-one comparisons could be made.

2. Core power loss comparison with different sized cores of the same material.

 

 

Large cores of the same material were found to have significantly higher losses when compared on the basis of mw/cm3.  This suggests that core loss for different core sizes cannot be calculated based on material specifications, which are usually taken using a "standard" core of about 2.5 cm outside diameter.

3. Core shape effect on power loss

 

Core losses were significantly lower for a core that was laminated.  The second core above has the same area, volume and weight as the first core, but it comprises 5 thinner laminations.

 

Core losses were significantly lower for a core that was hollowed out.  The second core has the same ID, OD and height as the first core.  Its area, volume and weight are lower, so higher losses may be expected at very low frequencies.

 

The four cores above all are the same weight and volume.  Cores 1, 2 and 3 have the same ID but cores 2 and 3 are stacked and have the same area, volume and weight as core 1. Core 4 has five times the area because it is wound with only one turn, but it has the same volume and weight as the others. 

The inductances of the four cores are very close to the same value, as are their other electrical properties except the core loss.  The multi-core stacks have significantly lower core loss.

4. Ferrites electrical properties

The electrical parameters (permittivity, permeability, and conductivity) of various ferrites were measured.  These must be known accurately to model the core performance successfully.

As an example, Finite Element Analysis (FAE) did not model the observed flux distribution very well using traditional parameters from data sheets.  Once the analysis was modified to use accurate parameters, the analysis was greatly improved.

5. Rectangular wave core loss tester

Part of the Phase II core loss program was developing an improved full-bridge rectangular wave driver for core loss testing.  The wave shape is determined by an arbitrary waveform generator under software control.  The voltage is controlled by a programmable power supply.  The time, voltage and current are measured using a high accuracy digital sampling oscilloscope and the parameters are exported to a spreadsheet for post processing and storage.  All of the software operations are written in Python.

PSMA Magnetics Committee

In addition to sponsoring these five core loss studies, the PSMA Magnetics Committee continues to be very active. They have organized 5 "Power Magnetics @ High Frequency" workshops in addition to conducting very successful APEC Industry Sessions each year.  They also presented two educational webinars as part of the "PSMA Basics of Magnetics for Switching Power Webinar Series" in early 2020. The committee meets about once a month by webconference and anyone interested is invited to participate. Contact the PSMA office at power@psma.com for more information.

iNEMI Publishes Best Practices for Protecting the Reliability and Integrity of Electronic Equipment when Disinfecting for COVID-19

The International Electronics Manufacturing Initiative (iNEMI) today announced publication of “Recommended Best Practices for Protecting the Reliability and Integrity of Electronic Products and Assemblies when Disinfecting for SARSCoV- 2 (COVID-19).”

Developed by a team of experts from across the member organizations of the International Electronics Manufacturing Initiative (iNEMI), this document provides guidance on how to mitigate the possible detrimental impact of disinfecting procedures on electronic equipment and assemblies. Groups such as the U.S. EPA, CDC and the World Health Organization (WHO) have published general guidelines regarding cleaning and disinfecting for COVID-19, but none of these specifically address the impact of disinfectants and their application methods on electronic equipment and assemblies. Many commonly recommended disinfection substances and/or application methods could potentially cause failures in electronic equipment.

To develop these best practices, the iNEMI team reviewed key industry, government and technical sources. They also assessed the chemicals included in the U.S. EPA List N: Disinfectants for Use Against SARS-CoV-2 (COVID-19) and common application methods, identifying those substances that minimize the risk of negative impact on electronic equipment when applied in an appropriate manner. 

“With the COVID-19 crisis, several of our members have contacted iNEMI for guidance on how to mitigate the possible detrimental impact of disinfecting procedures on electronic equipment and assemblies,” said Marc Benowitz, iNEMI CEO. “There are guidelines from groups such as the U.S. EPA, CDC and the World Health Organization (WHO) regarding cleaning and disinfecting for COVID-19, but none of these address the impact of disinfectants and their application methods on electronic equipment and assemblies.” 

“Many commonly recommended disinfection substances and/or application methods could potentially cause failures in electronic equipment if the internal electronics were inadvertently exposed to them,” continued Benowitz. “This is an obvious concern for electronics manufacturers who are wanting to ensure the safety of their employees, supply chain partners and customers, while protecting the reliability and integrity of their products.”

Benowitz explains that, in response to this industry need, a team of experts from across iNEMI member organizations reviewed key industry, government and technical sources and assembled a best practices document. The team assessed the chemicals included in the U.S. EPA List N: Disinfectants for Use Against SARS-CoV-2 (COVID-19) and common application methods, identifying those substances that minimize the risk of negative impact on electronic equipment when applied in an appropriate manner. 

iNEMI’s best practices are now available to download here.
