Hongwei Gao

Dr. Hongwei Gao is an assistant professor in electrical and computer engineering at Montana State University. He received his BS and MS degree from Tsinghua University in Beijing, China, in 1990 and 1993, and his Ph.D from Texas A&M University in 2001, all in electrical engineering.

Dr. Gao’s teaching and research interests include power electronics, electric machines, motor drives, alternative source power systems and electric and hybrid electric vehicles. His group develops low-cost, high-efficiency DC/DC converters for residential fuel cell power systems, high efficiency DC/AC inverters for megawatt-level fuel cell power plants and control strategies for DC/AC inverters in megawatt-level fuel cell power plants.

Dr. Gao is a senior member of IEEE and a member of IEEE Power Electronics Society, IEEE Industry Applications Society and IEEE Industrial Electronics Society.
