| Research Abstract |
A package method using gas insulated medium is proposed for power semiconductor devices in the high temperature range to 450 degree C and high voltage (1.2kV) region. Experiments were performed on discharge inception properties by changing kind and pressure of gas medium, and a prototype package was made. In addition, SiC inverter was developed so as to succeed in driving a motor. The inverter was installed in an electric vehicle system with 600W class. Furthermore, a partial discharge measuring system for inverter surge was constructed using optical and electromagnetic detection sensors. It was found that relative humidity gives the most significant effect on partial discharge inception voltage.
