High-voltage power devices made on Silicon Carbide (SiC) semiconductor have the potential to make transformative impact in future energy and power electronics systems because of higher electrical and thermal conductivities, enhanced breakdown voltage capability, and improved field-reliability compared to the industry work-horse silicon. This talk will discuss the current state-of-the-art and future research opportunities in SiC power devices for a wide range of commercial and strategic power electronics applications.
Krishna Shenai earned the B. Tech degree in electronics from IIT-Madras, India in 1979 and PhD degree in electrical engineering from Stanford University, Stanford, CA in 1986. For over 40 years, Dr. Shenai has uniquely pioneered reliable power semiconductor and power converter technologies and has made seminal contributions to high-density power conversion. His research has shaped the world-wide industry and resulted in several key industrial products that are netting multi-billion dollar annual sales revenues. Some of these products include rugged low-voltage power MOSFETs and synchronous rectifiers, high-voltage high-speed IGBTs, broadband RF power transistors and power amplifiers, high-density resonant power converters, and wide bandgap (WBG) power devices. He is widely credited for initiating and pioneering the development of WBG power devices and reliable high-density power converters. Dr. Shenai has produced three dozen graduate students and founded and managed two successful VC-financed startup companies to successful outcomes. He has authored over 450 peer-reviewed archived papers, 3 books and 10 book chapters, edited 15 conference digests, and holds 13 issued US patents. He is a Fellow of IEEE, a Fellow of American Physical Society, a Fellow of American Association for the Advancement of Science, a Senior Fellow of The Computation Institute at The University of Chicago, a University Scholar of the University of Illinois, and a member of Serbian Academy of Engineers. Currently, he serves as a Distinguished Professor and Director (R&D) at NMAM Institute of Technology in Nitte, Karnataka, India.
