Silicon (Si) power devices were the devices of choice for high voltage and high power applications such as power electronics and pulsed power.  Si power devices are reaching their theoretical limitations in the areas of blocking voltage and thermal operation for some new power electronics and pulsed power applications. Because of the limitations of Si power devices, researchers are investigating new wide bandgap materials for high power applications.  The most advanced material that is currently being investigated is Silicon Carbide (SiC).  SiC has unique properties such as a wide bandgap, high critical electric field, and high thermal conductivity that make it very attractive for high voltage and high power applications.  This presentation will discuss the performance of SiC power devices operating under extreme conditions.  An introduction to SiC power devices will be given and the results of the performance of the devices under narrow pulsed, high current conditions.  A reliability study of SiC power devices will also be discussed.

Dr. Stephen B. Bayne received his Ph.D., MS, and BS degrees in Electrical Engineering from Texas Tech University.  After completing his doctoral studies, he joined the Naval Research Lab (NRL), where he was an electronics engineer designing advanced power electronics systems for space power applications.  After two and a half years at NRL, Dr. Bayne transferred to the Army Research Lab (ARL), where he was instrumental in developing a high-temperature Silicon Carbide power electronic program.  Dr. Bayne served as Team Lead at ARL, where he led the power components team and was responsible for advanced research in high temperature and advanced power semiconductor devices for Army applications. Dr. Bayne also served as Branch Chief of the Directed Energy Branch, where he managed 16 Engineers, technicians, and support staff, a multi-million dollar budget, and was responsible for recruiting, development, and performance evaluation of members in the branch.  After 8 years at the ARL, Dr. Bayne transitioned over to academia, where he is currently a Professor and Chair of Electrical and Computer Engineering at Texas Tech University.  His research interests at Texas Tech are Power Electronics, Power Semiconductor Devices, Pulsed Power, and Renewable Energy.  Dr. Bayne has over 200 journal and conference publications.  Dr. Bayne is also a military veteran, where he served four years in the Air Force.
