PSMA Committees Meet During |
||||||||||||||
| ||||||||||||||
 n addition to the Professional Seminars, Technical Sessions, Exhibits and other activities scheduled during APEC 2010, many of the PSMA Committees conducted business meetings to plan their activities for the coming year. The following is a brief review.
The Marketing Committee meeting included a luncheon and was well attended as usual. Frank Cirolia, Committee Co-chair reviewed the activities of the committee over the past year and led the discussion of possible activities for the coming year. The past year was a very busy one – the committee issued several press releases and updated the slide presentation which introduces PSMA and explains the benefits of membership. At the suggestion of the Marketing Committee awards were given for the best presentations in each track and poster session during APEC 2010. The Marketing Committee also conducted a review of the strengths, weaknesses, opportunities and threats facing PSMA which will be reviewed more thoroughly by the Executive Committee and the Board of Directors. Co-chair Lou Pechi led a lively discussion about the results of the most recent PSMA survey of the membership. The Magnetics Committee also held a meeting during APEC. Committee Co-chairs Steve Carlsen and Ed Herbert reviewed recent activities including results of phase 1 of a study on Core Loss conducted at Dartmouth University and discussed possible projects for the coming year that would provide benefits to the membership and to the industry. The Magnetics Committee also sponsored a Special Presentation session at APEC 2010 on Inductive Components.
The Packaging and Semiconductor Committees held a joint meeting and discussed the accomplishments of the past year and possible projects for 2010. The Packaging Committee also had a Special Presentation session at APEC about Power Supply on Chip. The Energy Efficiency and Alternative Energy Committees each met and reviewed their accomplishments during the past year. The Energy Efficiency Database on the PSMA web site continues to be popular with members and others in the industry. The data base is available on the PSMA web site and is updated on a regular basis. The Alternative Energy Committee presented a Special Session at APEC on Power Electronics and Alternative Energy. The Nanotechnology Committee, chaired by Tony Laviano and Chuck Mullett, also had a Special Presentation Session at APEC on Nanotechnology. In addition to that, Tony was a speaker at the Plenary Session. The committee has been quite active during the past year, with well attended monthly teleconferences. The Nanotechnology Forum on the PSMA web site has been updated with information for our members and the community at large. A complete listing of all PSMA committees can be found on the PSMA web site. Most of the committees manage their own Technical Forums on psma.com. The forums provide information on their current activities, upcoming industry events and resources, including useful web sites.
Participating in one or more committees is the best way to increase the benefits from your PSMA membership. You are encouraged to join a committee and get involved in their activities. You can see a list of committees on the PSMA web site. Most committees meet once a month for up to one hour by teleconference. You are welcome to attend a committee meeting before making a decision to participate with the group. View a list of upcoming committee meetings. If you are interested in attending one of the meetings, please contact the Association Office for call-in information. In addition to the meetings of the PSMA committees, there was a meeting of members who are interested in promoting PSMA activities in India. Dhaval Dalal led the meeting and continues to explore ways to expand PSMA in India.
The Technology Roadmap committee held a workshop which took place on the Saturday before APEC. Co-chairs Carl Blade and Aung Thet Tu led the workshop and recruited PSMA members to make presentations and participate in the 2011 Roadmap which is scheduled to be released before APEC 2011. Of course not all of the meetings at APEC were work related. This annual event is also a time for people to renew friendships and socialize with colleagues. After the workshop on Saturday, the Technology Roadmap Committee members relaxed over dinner and refreshments. There was a dinner on Sunday night for the APEC sponsors and on Tuesday evening PSMA hosted a Hospitality Suite which was well received and attended. The APEC banquet and entertainment took place on Wednesday night around the pool at the Renaissance Hotel.

 A Company with Nimble Focus on Energy Efficient Power Solutions and Mobile Connectivity
Fairchild Semiconductor was established in 1957 by the pioneering group known as the Traitorous Eight that included Robert Noyce, Jean Hoerni and Gorden Moore. Named for Sherman Fairchild who agreed to fund the new company due to Noyce’s impassioned vision of using silicon substrate for a transistor, the goal of the original company was the development and production of silicon diffused transistors and other semiconductor devices. In 1958, Fairchild pioneered the planar process developed by Hoerni and with it a new industry of planer transistors. Two years later Fairchild built a circuit with four transistors on a single wafer of silicon, thereby creating the first silicon IC (Jack Kilby of Texas Instruments had also independently developed an IC made of Germanium in the same year). Fairchild quickly grew from twelve to twelve thousand employees, and became the cornerstone of the semiconductor industry spawning many new companies in the Silicon Valley (See Fig. 2).
In 1997, Fairchild became the industry's first multi-market semiconductor company producing logic, memory, and discrete technology. Today, the company is known as a leading global supplier of high performance power and mobile products, delivering energy-efficient, easy-to-use and value-added semiconductor solutions for power supplies, mobile, lighting, motor, computing, consumer and automotive applications. Along with the internal developments such as the PowerTrench® family of MOSFETs in 1998, Fairchild made many key acquisitions including the semiconductor division of Raytheon, Intersil’s discrete power business (making Fairchild the second largest power MOSFET supplier in the world), Impala Linear Corporation, Power Device Division of Samsung Electronics in South Korea, and System General of Taiwan.
Figure 3 summarizes the Fairchild power portfolio today. Fairchild’s key products for ac-dc, dc-dc and inverter solutions include:
With a long and rich history in the semiconductor industry, Fairchild is a leading global supplier of high performance power management products that maximize power efficiency at every opportunity. Additionally, Fairchild offers a wide portfolio of analog and power IP to support handset manufacturers’ specific requirements. These include complementary chipsets in signal path for audio, video, USB, and ASSP/logic and power management for peripheral cores, lighting and RF. The entrepreneurial spirit of the early Fairchild is alive and well today. Its leadership in energy efficient solutions and mobile connectivity makes Fairchild as important and relevant for the next 50 years as it has been for the last 50. Provided by Aung Thet Tu,
 Qspeed Semiconductor designs and manufactures discrete power semiconductors and currently sells the world's most efficient 300 V and 600 V ultrafast, Silicon rectifiers. Qspeed is a fab-less Semiconductor Company that is based in Santa Clara, California, the heart of Silicon Valley. Qspeed was founded in 2006, shortly after the first high-voltage (600 V), Silicon Carbide (SiC) Schottky diodes appeared on the market. Starting in the early 1990s, power supply manufacturers began putting active power factor correction (PFC) boost converter stages into their higher-power (500 W and up) power supplies, to make the supply's input current track its input voltage with a power factor that is close to one. Before 600 V SiC Schottky diodes were available, power supply designers used ultrafast Silicon (Si) rectifiers in their boost converters. The primary limitation of ultrafast Si diodes is the high amount of stored charge (Q) that must be removed from the device during its reverse recovery (Qrr). When a bipolar, Si rectifier is suddenly reverse biased while conducting a large amount of forward current, it cannot block the reverse voltage until it's cathode has been cleared of the minority carriers (holes) that the anode injects into it. As those minority carriers are swept back into the anode, they cause a transient reverse recovery current (Irr). The amount and duration of the Irr that is typical of standard ultrafast Si rectifiers causes power losses in the boost switch, which limits the overall efficiency of the stage and makes the diode the main component in need of performance improvement.
As the market demands for active power factor correction (PFC) and higher efficiency has continued to increase, Qspeed is developing products that address the needs of power supply designers. Since early 2006, Qspeed has designed several families of high-efficiency Si rectifiers, including a 300 V version of the Q-Series family and its newest family of 600 V devices, the H-Series. In total, Qspeed is now manufacturing and selling over 30 different devices that are specifically targeted for high efficiency, cost-effective solutions.
Qspeed has Sales and Distribution in Asia Pacific, Europe and the North America, along with strategically placed logistics hubs, for JIT delivery.

Big Opportunities In DC |
||||||||||
|
||||||||||
|
he introduction of dc powering architecture is expected to play a large part in the effort to conserve energy in a number of industries that traditionally consume large amounts of electricity. These industries include data centers and telecommunications facilities, both of which use large amounts of electricity without much regard for efficiency. In fact it has been an acceptable practice to trade off energy efficiency and operating costs for the sake of system reliability. However, in recent years a number of factors have emerged that may change that practice, and a debate is taking place on how to cope with the increasing need for electricity and the associated costs to power these facilities.
Traditional ac power architectures for data centers house a large amount of equipment, including individual servers, power supplies, back-up systems and additional energy consuming components. The individual power supplies within each server convert the ac input voltage into a voltage appropriate for the unit’s needs. Since the power supplies used in data centers are typically redundant, this results in an energy inefficient system which generates substantial heat which the room’s air conditioning system must remove at additional expense. The waste heat generated within these centers can also impose limits on the number of servers that can be housed within the data center and can jeopardize reliability if not handled properly. As a result, managers and other data center professionals are looking to dc power architectures as an alternative solution to the traditional ac power architectures. Proponents for a dc power architecture claim that it has the potential to eliminate the biggest source of energy loss and waste in traditional ac systems: the multiple back and forth transformations and conditioning needed to step voltage down for use by the load equipment. There can be up to six or more power conversion stages between the facility input voltage and the voltage required by the microprocessor or other data processing circuits. The argument is that the adoption of a dc power architecture system would allow the conversion of the high-voltage ac input to a dc voltage earlier, keeping it in a dc distribution voltage format and delivering it to rack-based servers. This same principal also holds true for telecommunications facilities. Although they already use 48Vdc power, they are starting to look a lot like data centers. Both data centers and telecom COs have been installing lots of IT equipment; both are adding new services and capabilities; and both are running out of power, cooling and space. Further adoption of a dc power distribution system in this industry may help overcome traditional constraints in the development of new transmission capacity. Not all dc power opportunities are in large facilities. Dc power can also be used to improve efficiency at the lower-voltage levels. The addition of dc power delivery systems to homes, office building and commercial facilities offers the potential for significant improvements in energy delivery efficiency, reliability, power quality and cost of operation. Most of these facilities are currently dominated by fixed overhead lighting and a variety of electrical devices that are typically wired for the building’s lifetime rather than the occupants or residents evolving needs. As a result, building designers and owners are looking for systems to make buildings more adaptable and allow the integration of infrastructure, equipment and furnishings that can improve energy efficiency. Addressing these concerns will lead to the further deployment of new power, control and device-level technology designed for commercial interiors and developed around the use of safe low-voltage direct current power. Although opportunities exist in both new installations and retrofits, according to the EMerge Alliance, which was established to promote the rapid adoption of safe, low-voltage dc power distribution and use in commercial building interiors, 80% of the market opportunities are in the updating and retrofitting of commercial buildings. In fact, the ability to distribute low-voltage dc power within common infrastructures is already present in commercial interiors. As an example, dc power is ideally suited for integration in the ceiling plane, providing facility managers with the ability to readily arrange and rearrange lighting, sensors, actuators and other devices without the need for rewiring. The adoption of dc power also embraces the trend towards using on-site alternative energy sources such as wind or solar power, by providing a means of direct and more efficient connection between the new energy sources and interior electrical loads, like lighting and controls.

Rosenfeld: A New Unit for |
||||||||||
|
||||||||||
 riting in Environmental Research Letters (January—March 2010 Issue) Dr. Jonathan Koomey and more than fifty other scientists, engineers and researchers, associated with energy efficiency and savings issues have proposed a new unit to measure energy savings. It will be called The Rosenfeld, in honor of Arthur Rosenfeld widely acknowledged to be the Father of Energy Efficiency.
In the Energy Environmental community Arthur H. Rosenfeld holds one of the unique reverent places and is widely admired by colleagues for creating policies that have been at the forefront of environmental movement that is currently shaping the worldwide discussion of power generation, energy consumption, and climate change. Dr. Rosenfeld had a foresight to imagine these energy issue more than 30 years ago, when he switched his field from particle physics to the study of energy and environment in 1975. Rosenfeld’s name for the energy saving unit is well deserved and similar to the names associated with Volt (Alessandro Volta), Watt (James Watt), Joule (James Prescott Joule) and Coulomb (Augustine de Coulomb). There is a great tradition in scientific community to assign a scientist or a major contributor’s name to the unit that is assigned to the emerging respective science. In simple terms, one unit of Rosenfeld is equivalent of avoiding one coal fired power plant with 500MW of electricity generation capacity. This is equivalent of saving 3 billion kWhr of electricity at the meter, which is equivalent of saving 3 million metric ton of carbon dioxide (CO2) per year. Dr Jonathan Koomey’s paper “Defining a standard metric for electricity savings” provides details about the selection criteria for this unit such why “avoidance of 500 MW of coal fired power plant” was selected. Though at first it looks arcane, Dr. Koomey makes a fairly easy to understand argument for choosing this criteria. However, the main point of selection is succinctly summarized in the conclusion or the abstract of the paper; “...The Rosenfeld can best be used in rough back-of-the-envelope calculations and high-level summaries of analysis results for less technical audiences… These parameters satisfy the initial criteria of simplicity of presentation, ease of recall, intuitive plausibility, physical meaning, and policy relevance…” The original idea for this unit was thought out by Chris Calwell of Ecos Consulting, a well known personality in the power supply community due to his participation in APEC and his contact through PSMA’s Energy Efficiency Committee. Dr Jonathan Koomey (another know personality) made this proposal into reality. The power electronics community should be very proud of Dr Arthur Rosenfeld and his contribution to the energy savings policy. The US EPA can take steps to make Rosenfeld Unit to be widely accepted and used. Every year EPA, through its ENERGYSTAR program, announces amount of savings in electricity. For example, in 2009 through the ENERGYSTAR programs, the United States saved 191 billion kWhr of electricity which would be 67.7 Rosenfelds. If EPA charts its graphs in Rosenfeld, the unit will be widely used by the electrical engineering community. Coincidently, US Energy Secretary Dr Steven Chu was a former Director of Lawrence Berkley National Laboratory at University of California, Berkeley, the same organization where Dr Arthur Rosenfeld worked as a scientist before joining the California Energy Commission. A simple mention of Rosenfeld by Dr. Chu in one of the numerous press conferences will go a long way to popularize Rosenfeld as a new unit of electrical energy saving. You can read the entire article “Defining a standard metric for electricity savings” by Jonathan Koomey www.erl.iop.org and read Dr. Arthur H. Rosenfeld’s bio on www.energy.ca.gov (California Energy Commission web site). The views expressed in this article are solely of Mohan Mankikar's alone. They do not represent view of PSMA. Mohan Mankikar has been a part of the power supply industry for over twenty years, has been an active member of PSMA since its founding, and has been on the Board of PSMA and currently acts as an advisor.

Solar Market Booms – But A Lack Of Inverters May Cause |
||||||||||
| ||||||||||
|
n the past, inverters have often been an overlooked part of the solar Photo Voltaic (PV) supply chain – probably because they account for only a small proportion of PV system costs. Recently however, inverters have become critically important, because their poor availability delayed the connection of hundreds of solar installations at the end of 2009. A new report from IMS Research reveals that the total solar power new installed capacity grew to 7.4 GW in 2009, more than half of this being in Germany alone. There was an even greater growth in PV module and inverter shipments; inverter shipments grew some 35% over the previous year, despite the very slow start to 2009 and the collapse of the largest market at the end of 2008. Installations surged in the second half of 2009, partly fueled by speculation of cuts to Germany’s feed-in-tariff; and strong demand continued well into Q1’10. The total industry production capacity of inverters, unlike that of PV modules, is not massively higher than annual demand. In addition, whilst there are several hundred module suppliers to fill the gap between supply and demand quickly in a rapidly growing market, the much more consolidated inverter market was not able to adapt quickly enough to the rapid increase in demand seen at the end of 2009. The industry was not able to ramp up the production required. Thus a lack of inverters caused a major bottleneck at the end of 2009, which is continuing to affect the entire PV industry in a big way. This spiraling demand has left PV inverter suppliers also facing major problem of supply. Very long lead times (of up to 6 months) for critical components, such as IGBTs, have left manufacturers limited not only by their own production capacity, but also by the availability of components. Hence the long lead times for inverters are continuing to limit the expansion of the PV market further, with PV system integrators already reporting harm to their business caused by this bottleneck. While the fulfillment of demand is being limited by the current inverter supply, demand will undoubtedly slow in the Q3 when the German market stagnates. However, annual installations in 2010 are still forecast to grow by some 60-70%. This would lead to a PV inverter market of about $5 billion – far from insignificant! Demand in 2009 was extremely volatile and varied significantly by country. Thus supplier market shares and rankings have changed significantly in the last year. SMA retained its position as the world’s largest supplier with an annual market share that has increased each year for several years and reached close to 40% of total global revenues in 2009. However, several new entrants have entered the IMS Research’s top supplier rankings and many, perhaps with better access to components, may be better placed to take advantage of the booming market.

Second International Workshop On Power Supply On |
||||||||||
| ||||||||||
|
 Following the overwhelming positive feedback from PwrSOC`08, a second International Workshop on Power Supply on Chip will once again bring together the key players from both the industry and academic communities active in the emerging area of system-in-package (SiP) and system-on-chip (SoC) solutions for power supply miniaturisation. Organized by Tyndall National Institute, one of Europe’s leading research centres, PwrSOC’10 plans to build on PwrSOC’08, which drew an international audience of over 120 experts from companies, universities, and research institutions. A major challenge to the further miniaturisation of DC-DC converters is the inability to integrate passive components on silicon due to their relatively large size at today’s operating frequencies of 0.5 to 5 MHz. Increasing the switching frequencies into the 10 to 100 MHz region offers the potential for the reduction of passive component values to the point where, with the right technology, their size becomes compatible with silicon device dimensions. Currently, significant R&D and product development activity is evident in advances in semiconductor, magnetic, capacitor and packaging material technologies that will deliver products operating at multi-MHz frequencies. The ultimate target is to develop new miniaturised product formats that can be referred to as power supply-in-package (PSiP) and power supply-on-chip (PwrSoC). This space has been under increasing focus from semiconductor companies due to their ability to deliver advanced silicon processing technologies and functional integration with increased reliability. This proliferation of functionally-integrated hardware solutions can be seen as an inflection point in the power supply industry which is seeing a dramatic move away from traditional power supply manufacturing (with a focus on the assembly of power supply modules or bricks from discrete components) to an increasing emphasis on power supply products derived from semiconductor and microelectronics platforms and technologies. The speakers and conference organizers agreed that the interdisciplinary approach of PwrSOC’08 workshop was essential to the successful development of power supply-on-chip technology. Application needs, technologies, manufacturing ability, and packaging have all converged to the point that a power SoC solution is not only possible but quite likely required in certain applications. Semiconductor manufacturers, materials researchers, system makers, and power supply designers all need to come together to address the problems of functional and packaging integration. The first PwrSOC workshop was thus a significant step in that direction and the upcoming second workshop is positioned to result in further significant progress in this field. Dr. Cian Ó Mathúna, co-chair of the PSMA Packaging Committee put the value of the workshop in context: “this concept of integrated power solutions presents a significant disruptive opportunity in power management solutions and warrants an international forum for its discussion and for the elucidation of the key challenges that lie ahead”. Tyndall is supported in the organisation of the workshop with technical co-sponsorship by the IEEE Power Electronics Society (PELS) (http://www.ieee-pels.org), the Power Sources Manufacturers Association (PSMA) (http://www.psma.com), and the European Centre for Power Electronics (ECPE) (http://www.ecpe.org Information updates for the workshop will be available in the coming weeks on www.powersoc.org For further information, contact Dr. Cian Ó Mathúna, cian.omathuna@tyndall.ie or Brice Jamieson, brice.jamieson@tyndall.ie
