About

Tsutomu Kominami is a leading researcher in power electronics and motor drive systems, best known for his pioneering work on the nine-switch inverter topology. His most influential contribution, detailed in a highly cited 2007 paper, introduces a novel inverter design capable of independently controlling two three-phase loads—such as motors in industrial robots, electric vehicles, and trains—using only nine switches instead of the conventional twelve. This innovation significantly reduces component count, cost, and system complexity while maintaining high performance, making it a landmark advancement in multi-motor drive applications. With over 340 citations across his key publications, Kominami’s work has had substantial impact on both academic research and practical industrial design. His research addresses critical challenges in energy efficiency and compact power conversion, influencing the development of more reliable and economical electric drive systems. Kominami’s contributions continue to inspire further studies in multi-port inverters and advanced motor control, cementing his reputation as a key figure in modern power electronics.
