Abstract

Very large number of power semiconductor devices(switch) are used in power electronics systems such as AC adapters for PCs, DC-DC converters for CPU, motor driver systems and induction heating systems for home appliances. This paper describes the possibility of GaN-HEMT for power electronics applications. The key design issue is to obtain high breakdown voltage of 600V with the HEMT structure. We employed the field plate structure to relax the electric field peak at the gate electrode edge. A high voltage DC-DC converter operation was also experimentally demonstrated showing possibility of the GaN-HEMT for power electronics applications.
