The attendance for this year bears out the popularity of this location as well as signs of revival of our industry so impacted by the great recession of 2008 - 2009. Registration reached nearly 2,600 individuals – up a full 20% over last year. Over 900 people signed up for the combination of educational seminars and full conference technical sessions.
The plenary sessions were in my observation, the best attended in many years. My unofficial estimate of attendance on Monday afternoon was well over 1,000. Over 300 technical sessions were presented. The tradeshow was, as always, a lively and well-attended venue for networking and learning about the latest new products. The opening night of the tradeshow was marked by the cutting of huge cakes decorated to mark the 25th anniversary of APEC – which without a doubt is the leading technology event for the industry.
And now it’s on to APEC 2011. We’ll be heading back to the heart of Texas next year. So mark your calendars and plan to be there with us in Ft. Worth next March 6 – March 11.

PSMA Annual Meeting Attracts A Crowd! |
|||||||||||||||||||||||||||||||
| |||||||||||||||||||||||||||||||
Attendees included many of the twenty-two students who were given the APEC 2010 Attendance Award of up to $1000 by PSMA this year. There were a record number of applications competing for the award. The terms of office for four of the existing Directors expired at the 2010 Annual Meeting. Chairman Dusty Becker recognized the contributions of Cian O’Mathuna and Rob Hill, who are both leaving the Board and expressed the appreciation of PSMA for their service and continued contributions to the Association. The following were elected to the Board of Directors for the three-year term 2010-2013:
The attendees congratulated the new Directors and Dusty welcomed them to the Board of Directors. Following the election of Directors, Dusty Becker reviewed the PSMA activities and notable accomplishments for the year 2009 and discussed his objectives for the Association in the coming year.
Dusty reviewed and welcomed the list of the new members, which included four Regular members, two Associate members and eleven Affiliate members. A number of special projects were completed this past year including publication of the 2009 Technology Roadmap, organization of four full Special Presentation Sessions at APEC 2010 and financial support for 22 students to attend APEC 2010. The Alternative Energy Committee has been re-energized with two new co-chairs. The PSMA website continues to attract a growing number of visitors and is scheduled to undergo a complete renovation in 2010. Dusty also stressed the contributions of the PSMA committees and encouraged all PSMA members to get involved with a committee as a sure way to increase the benefits of membership. Following the Chairman’s Report was a financial report provided by Secretary/Treasurer Michel Grenon and individual reports by each of the PSMA Committee Chairs. At the meeting, Dusty presented Frank Cirolia, Ed Herbert and Kevin Parmenter each with a plaque in appreciation of their outstanding contributions to PSMA. Frank has served as PSMA Vice President and Secretary/Treasurer, is currently co-chair of the Marketing Committee and the PSMA representative on the APEC leadership track. Ed is Co-chair of the Magnetics Committee and is active on several other committees. Kevin has been PSMA President and Marketing Committee Co-chair, and served as the General Chair for APEC 2009 in Washington, DC.
Babak Fahimi, General Chair for APEC 2010, reported that registration for the seminars, technical sessions and exhibits should set new records. There were a record number of digests submitted and the exhibit booths were sold out. In addition, there was good representation by the press and financial communities. In short he reported that APEC 2010 will be very successful from both a technical and financial viewpoint
Patrick Chapman, Technical Program Chair for APEC 2010 and the General Chair for APEC 2011, briefly reviewed planning for that conference. APEC 2011 will be held at the Fort Worth Convention Center in Fort Worth, Texas March 6 – 10. The committee is looking forward to a very successful conference in Fort Worth. Guest speaker Brian Fortenberry, Program Manager, Energy Utilization from EPRI (Electric Power Research Institute) discussed the Smart Grid work being conducted by EPRI and provided an overview of the demonstration, methodology and projects currently underway and planned.
He was followed by Mr. Takashi Takeda, research engineer from NTT Facilities, who discussed the high voltage dc power distribution system being developed. This system will result in significant energy savings and will be installed in data centers starting in 2010. These presentations generated a great deal of interest and each was followed by a brief question and answer period. The Annual Meeting was immediately followed by the February Board of Directors meeting. Most of the PSMA Committees held meetings during APEC 2010 to set their programs for the upcoming year. The individual committee reports will be featured in future issues of the Update. |

Shaping Efficiency Using CHiL Semiconductor Digital Algorithms The onslaught of efficiency requirements emerging throughout the computing industry for multiphase DC-DC voltage regulators has caused a major shift in VR solutions. While industry specifications such as Climate Savers or Energy Star for computing do not specify exact DC-DC efficiency requirements, they make it clear that efficiency from 20% to 100% load needs to constantly improve. Major OEM customers, especially in the server industry, are demanding even higher efficiency than the industry forums indicate. CHiL Semiconductor Corporation has implemented several digital algorithms in their digital power management IC families, to shape the efficiency across the entire load of the CPU as well as the memory. Efficiency Evolution and Shaping The efficiency of VR solutions, whether for CPU or Memory on Servers, or for Graphics controllers on graphics boards or in High Performance Computing applications, has evolved over time as a function of cost and size. Total Cost of Ownership (TCO) has entered into the equation as well as the concern for Greener solutions, driving the need for higher efficiency. Figure 1, indicative of multiphase systems converting 12V to 1.2V, highlights the evolution of efficiency in servers over the last several years.
CHiL’s digital algorithms combine to create a shaped efficiency curve, that results in the high efficiency across the entire load line. It is accomplished through two primary methodologies – Dynamic Phase Control as well as Variable Gate Drive. Dynamic Phase Control Dynamic Phase Control (DPC) is the fast, controlled management of phases in a multiphase VR solution, combining the shedding of phases as a function of average current, and extremely fast and controlled addition of phases as a function of peak or transient currents as well as average current. Phase shedding, as it has been coined, is quite easily implemented in VR solutions. By simply measuring the average current and reducing the number of operating phases, switching losses can be mitigated. While a simple concept, it has not been effectively implemented in Servers in the past because of the need to respond to large increases in current due to CPU, Memory or GPU transients. Adding phases slowly is an unacceptable solution as it will (a) result in the saturation of inductors or (b) will require an excess of bulk capacitors on the output of the VR solution to hold the voltage while the phases are added. CHiL’s non-linear approach to the addition of phases overcomes these issues. A six phase server VR solution utilizing DPC is shown in Figure 2, where the load current is changed at high speed from 105A to 30A and back to 105A. This example utilized no more bulk capacitors than is required for normal transient responses. The response to a load release is a controlled dropping of phases one at a time to reach the ideal efficiency operating point at 30A which is two phases in this example. The response to the load step increase is very fast controlled turn-on of the phases in order to ramp the current in the inductors and drive the current to the load. A careful examination of the timing of the 4 additional phases turning on will show that they are not turned on exactly at the same time. The algorithm used manages the timing frequency and pulse width of each phase turning on to minimize overshoot but to also minimize common analog problems such as ringback, the overshoot caused by driving too much current into the output stage too quickly.  Variable Gate Drive A second mechanism to achieve higher efficiency across the load is to manage the gate drive to the MOSFETs or powerstage device as a function of the load current, called Variable Gate Drive (VGD). Normal server solutions usually choose a gate drive voltage that is either 12V, 5V or an intermediate voltage that is chosen to optimize the RDSon at only one operating point. Some systems will toggle between 12V and 5V at lower currents. No one fixed gate drive voltage is ideal. CHiL has implemented a programmable gate drive algorithm that allows the user to vary the gate drive voltage from any point at low currents to any other point at higher currents. A typical example may vary the voltage from 5V to 9V. 5V operation at lower currents save significant gate drive losses while 9V operation at high loads reduce RDSon to its minimum value while not overdriving the MOSFETs, i.e., 12V operation. The effects of VGD in a low cost four-phase desktop design are shown in Figure 3. Dynamic Phase Control, discontinuous mode and PSI operations are turned off to show the effects of varying the gate drive in the system. The efficiency is improved by 10% at 10A, and by 1-3 % at higher currents. Conclusion Implementing the Dynamic Phase Control and the Variable Gate Drive algorithms as shown in this paper result in a shaped efficiency that increases efficiency across the entire load. Likewise, these algorithms are independent of any particular power devices or gate drivers, so that any VR solution can improve the efficiency above what they have, not matter what device they are using.Provided by David Williams, Editors Note: We would like to feature your company in a future issue of the Update. |

Explosive Growth Projected For Wireless Power And Charging |
||||||||||
|
||||||||||
|
During 2009 there was significant activity in the wireless power market as the technology became targeted at mainstream applications. Perhaps some of the most notable were from Palm which released its Touchstone™ inductive charger for use with its Palm Pre handset via an add-on battery case, Dell which released its Latitude Z notebook which has integrated wireless charging capability using Fulton Innovation’s inductive technology and Powermat which released a range of inductive chargers and sleeves/cases which when added to portable applications, enables them to be charged wirelessly. Though other wire-free power and charging technologies exist and are being offered (such as conductive, RF and infrared), there is currently a larger industry focus on inductive technology, with many new start-ups appearing on the market and major OEMs now investigating the technologies. Wireless power and charging offers a universal solution to consumers, allowing them to power or charge multiple applications, whilst only having one charger connected to a power source. Many wireless power solutions also offer greater intelligence than a traditional wired charger enabling them to switch off when they are not charging, eliminating the vampire effect . They can also achieve close to zero standby power when no load is connected. IMS Research’s recently released report, “The Growth Potential for Wireless Power & Charging”, projects that the number of equipment enabled with wireless power will grow five-fold in 2010 and will continue to grow to almost one billion in 2019. This explosive growth is predicted to be driven largely by adoption of the technology in cell phones, though IMS Research believes that there are some key industry hurdles which will need to be overcome in order for mass adoption. Firstly, interoperability is one of the most important issues facing the industry. The ability to use enabled devices with any wireless charger, rather than a proprietary solution is imperative to fuel future adoption. The Wireless Power Consortium (WPC), a focus group made up of suppliers involved in the industry, has been working on an interoperability standard aimed at low power (5W and below) inductive charging for some time and is due to release version 1.0 of the standard shortly. Secondly, the cost of implementation needs to be reduced to allow OEMs to integrate the technology into their products at a cost that consumers can bear in return for the benefits and convenience of the technology. Prices will of course fall as adoption increases, volumes rise, and more competition in the market emerges. Thirdly, wireless power and charging solutions are not as efficient as wired solutions. The major emphasis on energy efficiency could present an issue for acceptance by some OEMs and consumers. There is a trade-off between the convenience to consumers and the reduced efficiency which will ultimately result in higher power consumption costs. Finally, but perhaps most importantly, the health and safety unknowns surrounding the use of wireless power transfer technologies may initially discourage some consumers, which may hinder uptake and market growth. Although almost all of the solutions currently available are aftermarket add-on solutions, IMS research predicts that major cell phone OEMs will soon begin integrating wireless power and charging capabilities into their products. This is projected to fuel adoption of integrated solutions into other applications and drive growth in the market. Integrators of equipment such as furniture and vehicle interiors have also been working closely with wireless power and charging solution providers. They aim to integrate the technology into their products to create an attractive charging environment for consumers. For example, a desk with an integrated wireless charger that would be capable of charging a cell phone, notebook and other compatible electronic devices without plugging them in individually. IMS Research predicts that a level of infrastructure such as this will drive OEMs to adopt and integrate the technology and also drive more widespread consumer use. The total opportunity for wireless power and charging is forecast to exceed $17 billion by 2019. Wireless power solution providers, power supply manufactures, OEMs, semiconductors and component suppliers and integrators are all well poised to take advantage of this.

UL Environment: A New Game For Energy Efficiency Marking |
||||||||||
|
||||||||||
|
At first glance it seems that this in "another money-making" scheme from a third party, the UL. When asked about this new ULE venture, initial reaction from many power supply companies was generally negative. A third party "intrusion", call it testing or labeling, that costs money and time is not popular with the manufacturers. UL is known for its safety regulations and getting on the energy efficiency bandwagon seems opportunistic. But the issue is whether or not UL is opportunistic, as most companies are, or can it provide a valuable service to an industry that is currently fraught with confusing set of regulations and uncertain compliance. Will the UL proposal for testing and labeling of efficiency standards/regulation provide consistency, uniformity and simplicity to the ever burgeoning energy efficiency landscape? Many environmental standards such as the 80+ program and the ENERGY STAR® program have been developed by the US EPA (Environmental Protection Agency). The EPA has developed and specified various test procedure to assure compliance with these regulations and standards. The testing is performed by labs that are accredited by the EPA, which can be either manufacturers' own labs or third party testing. There are many third party labs that specialize in some specific products and cover specific tests. The EPA does a fair amount of policing of the products (and procedures) which claim these labels. UL will be just another third party laboratory. Or is it? UL's entry into the energy efficiency testing and labeling is an interesting inflection point. UL is a well known lab and a recognized brand, for safety regulation as most companies and people are familiar with its procedures and the logo. UL has an extensive network of labs around the country and have established relationships with other worldwide agencies that perform similar test and procedure. UL's safety programs are highly homogenized and it believes that it can aid in creating consumer confidence in energy efficiency testing and labeling as well. Most important, UL can assemble and manage the equipment and personnel to perform ever increasing complex test procedures that are expected to emerge. With its significant resources, UL could become a one-stop shop for many regulatory testing and labeling in safety and energy efficiency area. UL's role in energy efficiency testing and labeling cannot be viewed as a negative development. However, in one aspect UL seems different than other labs, in that it plans to issue its own Energy Efficiency Certification. The ULE press release states "... The EEC Mark will appear on products and the packaging of products that are proven to meet energy efficiency requirements as outlined by standards and regulations such as ENERGY STAR®, Natural Resources Canada (NRCan) and California Energy Commission (CEC). The EEC mark incorporates UL Environment's leaf encapsulating the familiar "UL" initials and includes the words "Energy Verified" in black text..." If the US EPA has already developed standards and guidelines to grant an ENERGY STAR® logo based on the efficiency performance of the product, why is there need for an additional certificate or logo from the UL Environment? Too many labels from different organizations will increase the cost of the products and confuse the buyer. A clearly defined single label is sufficient to convey the message of product's efficiency performance in saving energy and environment. ULE needs to focus its efforts and resources on energy efficiency test procedures as developed by the government agencies, instead of issuing its own certificates and logos. There is no need to re-invent the wheel. The views expressed in this article are solely of Mohan Mankikar's alone. They do not represent view of PSMA.

Energy Harvesting Crossing Over To Commercialization |
||||||||||
| ||||||||||
|
The question now is whether energy harvesting will remain a niche application or enable emerging applications such as wireless building control, medical devices, environmental monitoring, and tire pressure sensing. Demand can be measured by the kind and amount of products that are introduced for emerging applications. This was true for digital power management and control, which started with IC makers and moved into ac-dc and dc-dc converters. Pricing is always a critical crossover point, as well. Digital pricing had to reach parity with analog pricing. Evidence suggests that the crossover from the “Introduction” phase to the “Growth” phase will take place within this year. This is based on product introductions from EnOcean that started in 2002. By 2005, the second generation of products was introduced, and other companies were offering new products, as well. In 2006, Electronica featured many European companies that had first-generation products, while EnOcean was already on the second generation. In November, 2009, the EnOcean Alliance publicized their energy harvesting standard, which presently contains 50 equipment profiles supporting the development of a variety of solutions for building automation. The size of the installations is increasing, and third-generation products appeared in 2009. The appearance of third-generation products often signals the crossover into the Growth phase. Based on the timeline and company activity of the EnOcean Alliance members, energy harvesting is poised for commercial adoption, with market share increasing. The time it will spend in the Growth phase is hard to predict at this point, but this phase is marked by rapid acceleration in sales and significant gains in market share, overall. It will present a good opportunity for makers of energy harvesting solutions. The global economic crisis has affected sales of wireless sensor devices, but companies are still seeing opportunities during the downturn. Companies like Cypress Semiconductor, austriamicrosystems and Future Electronics were interviewed on this subject, and the general consensus was that the trend toward “more intelligent machines” would continue, with more – not less – sensing functionality built into devices. For example, the number of cars being sold might decline, but the number of sensors inside each car is rising. Some sectors have been affected more than others, according to these companies, particularly with the decline in new housing starts and other commercial construction. In a downturn, companies focus on efficiency and cost saving. Where they are able to do so, they will invest in systems that lead to more automation and greater efficiency, which in turn will lead to continued growth in the sensor market. Motion control, automotive and security systems were cited, in particular. Energy harvesting is being deployed, particularly in building automation sensor applications. Overall, however, it is still in the development stages. Industry players indicate multiple energy harvesting technologies will most likely be required, since each technology has its own set of advantages and trade-offs, depending on the application. Energy storage appropriate to energy harvesting is also critical, and such solutions – like thin-film batteries and supercapacitors – are now being introduced. As a result, wide-scale adoption is likely to require partnerships that include sensor manufacturers, ultra-low-power electronics manufacturers and energy harvesting makers. Power requirements of some portable devices can “overlap” with energy harvesting solutions, creating incremental markets. For example, a two-way Bluetooth earpiece device requires too much power for energy harvesting in active mode. In sleep mode, however, the power requirements are low enough that energy harvesting could be used. Thin-film batteries are small and can now be integrated into the wireless sensor system – and theoretically last the life of the system. This also provides customers with energy storage choices: traditional batteries; supercapacitors; or thin-film battery energy harvesting. Energy harvesting devices are still priced according to the perceived benefit of not having to change or rely on batteries. Therefore, energy harvesting devices inevitably cost more than batteries at a time in their development where demand and, in some cases technology, are insufficiently developed to drive mass production. Still, what will ultimately drive the sales of energy harvesting devices is the cost of copper versus silicon. Copper wiring is expensive. Silicon is cheap, and wireless technologies invariably rely on silicon, not copper. “Cutting the cord” is not just a matter of convenience; it is a less costly solution. The current transition into the Growth phase will provide companies with significant sales and “branding” opportunities for energy harvesting solutions.

Hilton Bonnet Creek Resort | Orlando, Florida USA June 6 – 10, 2010 | www.intelec.org
It is with great pleasure that I invite you to Orlando and the 2010 INTELEC conference. We will be holding our conference in the brand new Hilton Bonnet Creek Resort and Conference Center surrounded by Disney World. It promises to be a great venue for both the conference and for our non-conference attendees. Our industry faces many challenges this year and I hope that we, as industry leaders and trend setters, can chart the course for energy consumption for all methods of communications on the right path. Over the past years there has been a significant increase in the number of companies providing communications equipment and services. There have been great strides made in reserve power and reducing consumption of energy used for communications equipment. This year we are expanding our reach to all methods of communications and energy usage. With the necessity for thinking of newer ways to produce and use the energy we consume in a more efficient manner, we can better prepare our industry to reduce the cost of communications, while also positioning ourselves to be more environmentally aware of our responsibilities. We have changed our conference date to early June, to accommodate those with business requirements and families taking children out of school. Also, many of our previous conference attendees have requested that we minimize the conflicts between concurrent technical presentations. To help ensure that the participants are able to attend the technical session of their interest, we will be reducing the number of concurrent sessions. The number of technical presentations will be reduced, but the quality of these papers will be more in tune with the needs of the industry. While making these changes is a bit painful, it is just a precursor of the recognized needs to maintain the high standards that we as industry professionals must deliver to be more responsive, and to make further improvements to the INTELEC concept. I hope to see you in Orlando! Marc J. Durocher Chairman, 2010 INTELEC®

he mountains surrounding Palm Springs California reach to above 8,000 feet and are covered with snow in the winter months. Down in the Coachella Valley below, Palm Springs – long known as a refuge for the rich and famous – served as the venue for this year’s Applied Power Electronic Conference. While enjoying the bright, mid-70s days, many of the attendees I spoke with were happy we were here and not back in last year’s venue - snowed-in Washington DC.
On Wednesday evening, the outdoor social event was entertained by a troop of impersonators that harkened back to the heyday of Palm Springs. Dean Martin, Sammy Davis, Jr., and Frank Sinatra sang their old favorites. But the real highlight of the evening was when Marilyn Monroe brought Dean Veneable (APEC’s first General Chairman) up to the stage and serenaded him to the delight of everyone there. 
as it the breakfast buffet or the growing awareness of the benefits from membership in PSMA – or both – that attracted more than 60 people to the Annual Meeting of PSMA the Monday of APEC 2010 at the Palm Springs Renaissance Hotel? The PSMA members and guests who attended had a very busy and full morning.
or many years companies have been investigating the possibility of powering and charging electronic devices without the use of interconnecting wires. Various techniques have been developed, though for a long time these were adopted only by niche applications. A good example of this is the charging of electric toothbrushes. Though most consumers may not have realized, the majority of rechargeable battery power toothbrushes use wireless inductive power transfer between two coils, to recharge the battery. According to recent analysis from IMS Research, the use of wireless power and charging is no longer limited to these niche applications and the market for this technology is set for dramatic changes over the next few years.

nergy harvesting has been “emerging” for several years, but the technology is now poised to break out commercially, driven by developments in areas that are, themselves, emerging applications. The market got its initial acceptance in wireless building automation and control, with deployments in Europe. These opportunities spread to North America, where home automation and control technologies were added to the mix. Wireless sensor mesh networks provided challenges that energy harvesting could meet, particularly where battery use was limited or problematic. Energy efficiency, the Smart Grid, radiofrequency identification, and thin-film batteries all helped to advance energy harvesting solutions.
