OverviewAI-generated summary
Dereje Woldegiorgis' research focuses on power electronics, particularly the development and modeling of advanced inverter technologies. His work includes investigating hybrid silicon (Si) and silicon carbide (SiC) switches for high-efficiency, low-cost applications, such as in ANPC (Active Neutral Point Clamped) inverters. Woldegiorgis has published on control objectives, gate driving approaches, and packaging solutions for these hybrid switches, as well as precise electro-thermal power loss models for three-level ANPC inverters utilizing them. He has also explored active gate drivers for paralleling Si IGBTs and SiC MOSFETs and developed new hybrid voltage source converters with reduced active switch counts for HVDC applications. Woldegiorgis collaborates with researchers at the University of Arkansas at Fayetteville, including H. Alan Mantooth, Xia Du, Md Maksudul Hossain, and Rosten Sweeting. His scholarship metrics include an h-index of 10, with 37 total publications and 288 total citations.
