报告摘要：Growing population and economy of this planet require us to build up a sustainable society. In electric power conversion and motor drive, more energy- and resource-saving, efficient systems must be developed. Power devices are the key for efficient power electronic systems. In this speech, state-of-the-art power devices and their applications are presented mainly on SiC and RC-IGBT. They increase the output power density, reduce the consumption of natural resources, and increase the efficiency of electric systems. Especially, the impacts of SiC and RC-IGBT on electric railway and EV drives are great.
