In this paper, requirements of power devices for automobile applications are discussed , especially hybrid vehicles, and the development of GaN power devices at Toyota. AlGaN/ GaN HEMTs were fabricated and their characteristics were measured . The breakdown voltage was over 600 V. The drain current with a gate width of 31mm was over 8A. Observation by a thermograph image of the device under high current operation showed the AlGaN/GaN HEMT operated at more than 300 deg C. All the results of GaN are really promising to realize high performance and small size inverters for future automobiles.
