Mitsubishi Electric Develops World's Smallest SiC Inverter for HEVs
Will help to reduce energy loss, further miniaturize inverters and improve fuel efficiency in future
TOKYO, March 9, 2017- Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed a working model of an ultra-compact silicon carbide (SiC) inverter for hybrid electrical vehicles (HEVs) that is believed to be the world's smallest SiC of its type at just five liters volume. It also is believed to offer the world's highest power density of 86 kVA / L for two-motor HEVs, thanks to incorporation of full-SiC power semiconductor modules that achieve superior heat dissipation. Mitsubishi Electric's unprecedented new inverter offers improved placement, fuel and energy efficiency, and frees up vehicle interior space. Commercialization for HEVs, electrical vehicles (EVs), and others is expected sometime around 2021.
Ultra-compact SiC inverter (working model)
Going forward, Mitsubishi Electric will continue developing its super-compact SiC inverter for mass production, aiming for commercialization around 2021.
This development has been partially supported by Japan's New Energy and Industrial Technology Development Organization (NEDO).
Technical details will be presented during the National Convention of the Institute of Electrical Engineers (IEEJ) from March 15-17, 2017.
