The
Future of Passive Components for High-Frequency
Power Conversion and Wireless Power
Transfer
Abstract
Power electronics is based on switched circuits with short-term energy storage in passive components such as capacitors and inductors. Advances in wide-band-gap semiconductors are resulting in extremely high performance switches, leaving the passive components as the limiting factor in improving performance. This talk will consider prospects for improved passive components from the perspective of their role in providing energy storage on the microsecond time scale. This leads to consideration of potential advantages of electromechanical resonators as well as to improvements in electromagnetic resonators. Implications for power electronics circuit design and for development of future passive component technologies are discussed. Presently available technologies and design techniques will also be reviewed.
The importance of passive component performance is especially prominent in wireless power transfer, where efficiency and range is constrained by the quality factor Q of the resonant transmit and receive coils used. A new self-resonant structure that not only avoids the need for separate coils and capacitors, but also increases Q by a factor of six compared to similar conventional coils will be presented.
Biography
Charles R. Sullivan is Professor of Engineering at Thayer School of Engineering at Dartmouth and a Fellow of the IEEE. He received a B.S. degree in from Princeton University in 1987 and a Ph.D. from the University of California, Berkeley in 1996. He has published over 190 technical papers and holds 42 US patents. His research expertise includes modeling and optimization of magnetic and other passive components for high-frequency power conversion; thin-film magnetic materials and devices; and electromagnetic modeling of capacitors. His techniques for modeling and optimization of high-frequency power magnetics are widely used by designers and researchers.

Title: Designing Power Electronics in Discrete Time
Abstract: In recent years, power electronics as a field has been characterized by rapid growth in both applications and constituent technologies. New devices and materials, including wide bandgap semiconductors, combined with the growing popularity of soft-switching, quasi-resonant, resonant, multiresonant, switched capacitor, and hybrid converter topologies, expand the scope of viable designs. Increasing performance of state-of-the-art systems necessitates higher fidelity modeling to differentiate between vastly different circuit implementations. This talk will review some of the prior and ongoing power electronics research projects at the University of Tennessee, with focus on opportunities and pathways to improve modeling and design.
Biography: Daniel Costinett received B.S. and M.S. degrees in 2011, and a Ph.D. degree in 2013 from the University of Colorado Boulder. Since 2013, he has been an Assistant Professor in the Department of Electrical Engineering and Computer Science at the University of Tennessee, Knoxville (UTK). Prior to joining UTK, he was an instructor at Utah State University, in 2012. His research interests include resonant and soft switching power converter design, high efficiency wired and wireless power supplies, on-chip power conversion, medical devices, and electric vehicles.
Dr. Costinett is currently a Co-Director of Education and Diversity for the National Science Foundation/Department of Energy Research Center for Ultra-wide-area Resilient Electric Energy Transmission Networks (CURENT). He is also a Joint Faculty with the Power Electronics and Electric Machinery Research Center, Oak Ridge National Laboratory. He currently serves as Associate Editor of IEEE Journal of Emerging and Selected Topics in Power Electronics, and IEEE Transactions on Power Electronics.
