Rik W. De Doncker

With more than 40 patents, Rik W. De Doncker’s power electronics innovations for energy-efficient conversion and drive technologies have impacted applications ranging from electric vehicles to advancing development of the electronically controlled power grid. He developed the dual active bridge electronic DC-to-DC transformer in 1988, which was critical to energy supply systems for the NASA space station. His auxiliary resonant commutated pole converter developed in 1990 had important implications for efficient high-power converters. Developed in 1994, his converter controller for low-voltage batteries in electric cars extends vehicle range and has been incorporated by several car manufacturers. He co-developed the first medium-voltage static transfer switch, which has been deployed in the United States to prevent power grid sags.

Leo Lorenz has developed some of the most important innovations in power electronics, spearheading the movement from conventional power conversion technology to high-frequency and high-power methods. Working with Siemens Semiconductor in Munich, Germany, Dr. Lorenz developed the first ultrafast switching multidie direct copper bonded-based power metal-oxide-semiconductor field-effect transistor (MOSFET) module in 1986, which serves as the foundation of today’s power module technology. He also pioneered the product definition and concept engineering of the first ultrathin wafer non-punch-through (NPT) insulated gate bipolar transistor (IGBT) in 1987. His role in educating industry on device performance, thermal management, high-temperature operation, and reliability issues was crucial to the successful adoption of the technology. He also developed the “sandwich technology” (the basis for controlled integrated power systems) for advanced integrated power modules, which is an important component in home appliances and automotive applications. He also introduced the CoolMOS power semiconductor, used primarily for offline power supplies, which some engineers consider as one of the greatest achievements in the power semiconductor industry in the past 20 years.

An IEEE Fellow, Dr. Lorenz is currently a professor at TU-Ilmenau and president of the European Center for Power Electronics. Till 2011 he was a senior principal with Infineon Technologies, Neubiberg, Germany.

Praveen Jain’s advancements of power conversion methods have improved the use of power electronics for practical real-life applications, including the space, telecommunications, and computer industries. During the late 1980s, Dr. Jain developed a new class of single-stage ac-to-dc converters for high-frequency distribution systems that provided reduced mass and volume as well as conservation of stored energy on a spacecraft. During the 1990s, Dr. Jain was one of the first to propose using asymmetrical pulse width modulation control for constant frequency operation of resonant converters. This revolutionized the design of highly reliable, high-density power supplies for the telecommunications industry. He also developed a digital transient controller for ultra-high-speed computer processors to supply nearly glitch-free voltage to the processor without using energy storage capacitors.

An IEEE Fellow, Dr. Jain is professor, Canada Research Chair and director with the Centre for Energy and Power Electronics Research (ePOWER) at Queen’s University, Kingston, Ont., Canada.

2010 - Akio Nakagawa

Akio Nakagawa

Akio Nakagawa’s development of the non-latch-up insulated-gate bipolar transistor (IGBT), which switches power at high speed, created an indispensable power device now used in applications ranging from air conditioners to hybrid vehicles. Before Dr. Nakagawa’s pioneering work in 1984, IGBTs of that time were prone to failure or even destruction due to latch-up (a type of short circuit) caused by the parasitic thyristor of the IGBT. His invented design principles completely suppressed the latch-up even under high-voltage and large-current operating conditions. The ability to withstand the “load-short-circuit” condition for more than 20 µs exceeded the capability of existing bipolar transistors. This set the global standard for IGBT design and enabled its successful commercialization.

An IEEE Senior Member, Dr. Nakagawa is currently Technical Consultant of Nakagawa Consulting Office. He previously served as Chief Fellow of Toshiba Corporation Semiconductor Company, Tokyo, Japan from 2005 to 2009.

2009 - Tadashi Fukao

One of the most significant contributions that Tadashi Fukao has made in the power industry is on “Super High Speed Electric Drives and Bearingless Drives.” The impact of Tadashi Fukao’s work on high-speed drives can be seen in today’s acceptance of high rotational speed drives used in hybrid vehicles, mobile power generators, and vacuum cleaners. He studied high-frequency cycloconverters, which convert 50-Hz commercial energy into 400- or 500-Hz electrical power, and proposed generator and distribution systems with reduced physical dimensions. Dr. Fukao researched bearingless motors to overcome the problems that occur when motors with bearings operate at super high speeds. Bearingless motors allow alternating current motor drives to be used in space applications, harsh environments, food and pharmacy processes, and very high- and low-atmosphere environments where bearing maintenance and use of lubrication oil would present problems.

An IEEE Fellow, Dr. Fukao is currently an independent consultant to the Tokyo University of Science and professor emeritus at Tokyo Institute of Technology.

2006 - Deepakraj Divan

Dr. Deepakraj M. Divan is known for his seminal work in soft switching power conversion and the ability to take from the laboratory to the marketplace new technologies that protect equipment against power disturbances.

In 1995, while chairman and chief executive officer of Soft Switching Technologies in Middleton, Wisconsin, Dr. Divan created a switching technology that led to a new breed of power quality products – an electronic, uninterruptible power supply for industrial plants. The Dynamic Sag Corrector addressed the issue responsible for “blips” or voltage sags that last less than two seconds and are responsible for 96% of all power problems.

Today, more than 2,000 such systems are installed in the semiconductor, automotive and food processing industries to protect sensitive industrial automation equipment.

In addition, he developed the only public-domain power monitoring network in the United States. Called I-Grid, this Internet-based system monitors power quality at industrial and utility facilities nationwide. With more than a thousand monitors connected to the Internet, I-Grid provides a detailed, objective and time-stamped analysis of the entire power grid never before available. I-Grid data allows utilities to demonstrate the occurrence of widespread power quality events – even if the source is hundreds of miles away. I-Grid data also helps manufacturers diagnose unsolved downtime events.

Dr. Divan is currently a professor at the Georgia Institute of Technology and the founder of Georgia Tech’s Intelligent Power Infrastructure Consortium, where he is responsible for a research and teaching program focused on integrating power electronics, power systems and controls technology to create a smart grid. He is also Chairman and Co-Founder of Innovolt Inc., a Georgia Tech Venture Labs company that has developed the next generation of surge protection product. Current-in rush voltage surge suppressor, or CVSS, protects electronics equipment from both voltage surges and current surges that accompany voltage sags.

An IEEE Fellow, Dr. Divan has served as a Distinguished Lecturer for the IEEE Industry Applications Society and is the recipient of the IEEE Power Electronics Specialists Conference Best Prize Paper Award and the IEEE Transactions on Industry Applications Best Paper Award.

He has a Bachelor of Technology degree from the Indian Institute of Technology in Kanpur, India, and masters and doctoral degrees from the University of Calgary in Canada, both in electrical engineering.
