Title: Architectures and Topologies for High-Frequency, High-Density Power Conversion
Abstract: Magnetic components, including inductors and transformers, are often the largest contributors to the size and loss of power converters, and can be a key limiting factor in achieving higher efficiency and smaller sizes. This talk describes emerging approaches in the design of power electronics that seek to address the twin challenges of miniaturization and performance. Through architectures and topologies that minimize magnetic energy storage and utilize it more flexibly, the scaling limitations of magnetic components can be offset, leading to smaller, higher-performance power converters. Examples are provided illustrating the opportunities provided by such approaches towards higher performance systems.
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 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 and is the recipient of numerous awards including the IEEE R. David Middlebrook Achievement Award for his work in power electronics. He has co-authored ten IEEE prize papers in the area, and co-founded startup companies Eta Devices (acquired by Nokia in 2016) and Eta Wireless, Inc.
