IEEE PELS UK & Ireland Chapter PELS Day 2024 Hybrid Event

To celebrate PELS Day 2024, IEEE PELS UK and Ireland Chapter in collaboration with UK and Ireland Women in Engineering affinity group, Power and Energy Chapter, Industrial Applications Society Chapter, IEEE PELS TC11 Aerospace Power, and University of Leicester, is delivering a hybrid event with distinguished and guest lectures.

PELS Distinguished Lecture 1

Silicon Carbide Power Semiconductors: Device Modelling, Gate Drivers and Application, Prof Dimosthenis Peftitsis Norwegian University of Science and Technology

Abstract: Silicon Carbide (SiC) power semiconductors exhibit superior electrothermal characteristics compared to Silicon counterparts. Lower conduction and switching losses, higher operating temperatures and frequencies will impact the design and operation of power converters. Up to date, SiC MOSFETs are the most successful device technology. The first part of this lecture will provide the fundamental design and operating principles of SiC MOSFETs, as well as their static and dynamic modelling by utilizing experimental data. To accelerate simulation times, a real-time hardware-in-the-loop dynamic model of high-voltage 3.3 kV SiC MOSFETs will be presented. The second part will introduce the gate driving principles for SiC MOSFETS, and operational limitations using passive gate drivers. A particular focus will be placed on active and adaptive gate drivers that can shape switching and conducting operation of SiC MOSFETs for enhancing reliability. Finally, an overview of power electronics applications that can be benefited by employing SiC power semiconductors will be presented.

About the Speaker

Dimosthenis Peftitsis (Senior Member, IEEE) received the Diploma degree (Hons.) in electrical and computer engineering from Democritus University of Thrace. Xanthi, Greece, in 2008, and the Ph.D. degree from the KTH Royal Institute of Technology, Stockholm, Sweden, in 2013. In his final year of studies, he spent six months in ABB Corporate Research, Västerås, Sweden, writing his thesis. From 2013 to 2014, he was a Postdoctoral Researcher involved in the research on SiC converters with the Department of Electrical Energy Conversion, KTH Royal Institute of Technology, and from 2014 to 2016, he worked as a Postdoctoral Fellow with the Lab for High Power Electronics Systems, ETH Zurich, Zurich, Switzerland, where he was involved in dc-breakers for multiterminal HVDC systems. He is Professor of Power Electronics in the Department of Electric Energy with the Norwegian University of Science and Technology (NTNU), Trondheim, Norway, where he has been a Faculty Member since May 2016.

He has authored or co-authored more than 100 journal and conference papers, and he is the co-author of one book chapter and the presenter of 7 conference tutorials. His research interests lie in the area of power converters design using WBG devices (e.g., SiC and GaN) including adaptive drive circuits, high-performance device models, dc-breaker design for MV and HVDC systems, as well as reliability enhancement of high-power semiconductor devices, including reliability of SiC power switches. Professor Peftitsis is Associate Editor in the IEEE Transactions on Power Electronics and IET Power Electronics, and he was a Member of the Outstanding Academic Fellows Programme at NTNU in 2019-2023. Since 2018 he also serves as a member of the EPE International Scientific Committee. He is currently the Chairman on the Norway IEEE joint Power Electronics Society/Industry Applications Society/Industrial Electronics Society Chapter.
