  This talk describes ongoing research that seeks to address the twin challenges of miniaturization and performance of power electronics. New system architectures and circuit designs are introduced that enable dramatic increases in switching frequencies (e.g., into the 3-300 MHz range). Higher frequencies are desirable because they reduce energy storage requirements, but necessitate circuit designs that either compensate for or utilize device parasitics. Furthermore, design approaches for integrated power devices and magnetics are introduced that scale well to small sizes and high frequencies and enable improved integration. Experimental results from power converters operating at frequencies up to 75 MHz are presented to illustrate these emerging technologies.

■Speaker Biography:
  David Perreault received the B.S. degree from Boston University and the S.M. and Ph.D. degrees from the Massachusetts Institute of Technology, all in Electrical Engineering. He is presently Professor and Associate Head of the Department of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology. His research interests include design, manufacturing, and control techniques for power electronic systems and components, and in their use in a wide range of applications. Dr. Perreault is a Fellow of the IEEE. He received the Richard M. Bass Outstanding Young Power Electronics Engineer Award and the R. David Middlebrook Achievement Award from the IEEE Power Electronics Society, the ONR Young Investigator Award, and the SAE Ralph R. Teetor Educational Award. He has co-authored six IEEE prize papers in the area of power electronics, and is also co-founder of Eta Devices, Inc., a startup company focusing on high-efficiency rf power amplifiers for communications.
