  Jun-ichi Itoh was born in Tokyo, Japan, in 1972. He received his M.S. and Ph.D. degree in electrical and electronic systems engineering from Nagaoka University of Technology, Niigata, Japan in 1996, 2000, respectively. From 1996 to 2004, he was with Fuji Electric Corporate Research and Development Ltd., Tokyo, Japan and he was with Nagaoka University of Technology, Niigata, Japan as an associate professor. Since 2017, he has been a professor. His research interests are matrix converters, dc/dc converters, power factor correction techniques, energy storage system and adjustable speed drive systems.

    He received the IEEJ Academic Promotion Award (IEEJ Technical Development Award) in 2007. In addition, he also received the Isao Takahashi Power Electronics Award in IPEC-Sapporo 2010 from IEEJ, Prizes for Science and Technology (Development Category) from the Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology, April 2017, 4th Nagamori Awards, 2018 and so on. Dr. Itoh is a senior member of the Institute of Electrical Engineers of Japan, the Society of Automotive Engineers of Japan and the IEEE.


    The requirement of the high-power density for power converters becomes stronger and stronger. Nowadays, the volume of cooling system is smaller and smaller by appearing wide band gap devices such as SiC and GaN. In contrast, passive components such as inductor and capacitor dominate the volume of the power converter.

    In this presentation, the minimization technologies for passive components are introduced with many kinds of circuit topology and control. The ac-to-ac direct power converters not requiring smoothing DC capacitor, the active power decoupling circuit reducing smoothing DC capacitor in the single-phase ac converters, the current discontinuous mode control reducing interconnection inductors and FRT control for minimum inductor will be presented.
