Mitsubishi Electric Corp. said on May 23 that it had developed a silicon carbide output inverter that will aid the development smaller and lighter power-electronic equipment for cars, industrial machines and other applications.
Silicon has traditionally been used in power semiconductor devices, but silicon carbide is growing in popularity because it reduces power loss and cooling requirements, therefore cutting the size of the components.
Mitsubishi Electric’s new forced-air-cooled, three-phase 400V output inverter uses a silicon carbide metal oxide semiconductor field effect transistor and a silicon carbide schottky barrier diode, and offers a power density of 50kVA per liter.
