Abstract:
Recent advances have opened the door to power electronics operating efficiently at high frequencies (HF, 3-30 MHz) and above. In addition to improving power density and bandwidth in traditional power electronics applications, HF power conversion techniques can advance industrial radio-frequency (rf) applications such as plasma generation for semiconductor processing. This talk describes some recent developments in multi-kW power electronics operating at HF. Inverters and switched-mode matching techniques are described that can efficiently provide rf power into highly variable loads over a wide power range with high control bandwidth. These techniques hold promise for advancing frequency and performance of power electronics in many applications.
Brief Bio:
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 the Ford Professor of Engineering at MIT. 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 Member of the National Academy of Engineering, a Fellow of the IEEE and is the recipient of awards including the IEEE William E. Newell Award for his work in power electronics. He is co-author of seventeen IEEE prize papers in the area, and of the textbook “Principles of Power Electronics, 2nd Edition” (Cambridge University Press, 2023). Dr. Perreault also co-founded startup companies Eta Devices (acquired by Nokia in 2016) and Eta Wireless (acquired by Murata in 2021).
