Honda R&D Co Ltd and Rohm Co Ltd announced thattheyjointlydeveloped "the world's first" high-output powermodulecomposed ofonly SiC devices, for use in electric and hybridcars.

Rohm provided SiC device technologies, while HondaR&Dofferedpower module technologies.

The power module consists of a converter and aninverterandemploys a shot key barrier diode made of SiC and MOSFET,whichareboth manufactured by Rohm. The power module withstands1,200Vandits output current is 230A.

Rohm has been conducting research and development ofSiCdevicesand inverters jointly with Nissan Motor Co Ltd as wellasHondaR&D. In respect to inverters, Nissan recentlydisclosedaninverter manufactured by replacing the existing diodewith aSiCdiode (Seerelatedarticle).

Recently, research and development of automobilepowersystemsinvolving SiC has been accelerated. This is becausetheefficiencyof power systems can be enhanced by using SiCdevices,whiledownsizing the power systems.
