パワー半導体デバイスの最新動向

摘要

This paper discusses the history and recent progress in power semiconductor devices, which represent one of the most important technologies in power electronics.First, the fields of application of power semiconductor devices and the demands from power electronics application systems are explained. Next, the fundamental principles of operation and recent progress in MOSFETs and IGBTs, which have been major devices in recent years, are explained. Finally, the recent progress in and problems of new material power semiconductor devices, such as SiC and GaN devices, are discussed.Power semiconductor devices and magnetic devices are both important components in power electronics technologies. It is necessary to improve not only these components but also power electronics technologies to achieve actual energy saving.
