Research fields

We have been engaged in studies on power electronics, especially electric power conversion systems and the applications.

The power electronics is applied to various fields such as home electronics, industrial applications, vehicle and transportation field, and power distribution field. The technique, however, always has some problems to solve, for examples, higher efficiency, small sized systems, higher quality of the converted electric power, noise and vibration suppression, and higher perfoemance of driven tergets. Futhermore, challenges to the global environmental problems, rare metals and rare earths saving, and the development of suitable control for power conversion systems with new semiconductor devices such as SiC and GaN devices are required.

Based on the above situations, our current topics are follows;

(1) Improvement of characteristice for power conversion systems with wide-gap semiconductors,
(2) Development of higher perfoemance controller for motor drive systems,
(3) Development of higher efficiency power conversion systems for distributed power generation systems by renewable energy and energy storage systems, and
(4) Development and expanded usage environment of the circuit simulator "TAP-T" (Transient Analisys Programs, "TOKUZO").

Our techniques can be also applied to robotics and electric power-assisted systems as the advanced topics.
