Power electronics connect, convert, and control different forms of electrical energy, forming the critical interfaces between electricity generation, storage, and consumption. Advances in power electronics are essential to the continuing electrification and energy efficiency of modern society, including computing, communications, advanced manufacturing, and the electric grid.
Our research studies the fundamental theory and novel applications of high-frequency circuits, components, and control for improving the speed, efficiency, size, and reliability of power electronics. In particular, our approach focuses on highly multiplexed power topologies, high-frequency switching and modulation, and sophisticated coupled magnetic components to supply energy-intensive, wide-bandwidth power conversion applications such as plasma generation for semiconductor fabrication and point-of-load converters for data centers. By dividing power conversion processes into smaller series and parallel cells, we can simultaneously improve energy efficiency, reduce component size, increase the achievable control bandwidth, and enable sophisticated balancing and modulation.
Our research draws from expertise in numerous domains, including
Design, integration, and control of high-frequency power converters and circuits
Theoretical modeling of complex power electronics, including dynamics, modulation, and balancing
Electromagnetic and thermal simulation, co-design, and optimization
Modeling and fabrication of novel coupled and planar magnetic inductors and transformers
