SWISS IEEE PELS EVENT - Application of HV SiC MOSFET for Medium Voltage Converters"


SiC MOSFETs have brought improvements in efficiency, size, and weight to several applications such as transportation,

data center power supplies, and electric utility converters. These fast switching devices enable higher bandwidth control

and smaller filter size. Application of high voltage (10 kV) SiC devices have their own unique challenges in isolation, high

dv/dt rates, and this webinar will provide guidance on issues associated with using these devices in converters for utility

applications and some solutions in regards to high voltage power supplies, gate drives, and protection. The webinar will

include experimental results of using 10 kV SiC MOSFETs in an MMC module and power conditioning system (PCS) and

some of the challenges that were encountered.

Prof. Leon M. Tolbert


Leon M. Tolbert received the Bachelor’s, M.S., and Ph.D. degrees in electrical engineering from Georgia Tech. He worked

at Oak Ridge National Laboratory (ORNL), Oak Ridge, TN, from 1991 until 1999 on electric distribution and power quality

projects. He joined the University of Tennessee in 1999, and he is currently a Chancellor’s Professor and the Min H. Kao

Professor in Electrical Engineering and Computer Science. He is a founding member for the National Science

Foundation/Department of Energy Engineering Research Center, CURENT (Center for Ultra‐wide‐area Resilient Electric

Energy Transmission Networks). He is also an adjunct participant at ORNL. Dr. Tolbert is a Fellow of the IEEE and a

Registered Professional Engineer in the state of Tennessee. He is the deputy editor‐in‐chief of the IEEE Power Electronics

Magazine. He conducts research in utility applications of power electronics including microgrids, interface with

renewable energy sources, medium voltage multilevel converters, and the application of WBG power electronics.
