On Friday Nissan said it has developed the world’s first inverter using silicon carbide diodes for use in alternative-fuel vehicles, including fuel-cell vehicles, electric and hybrid vehicles. The inverter is regarded as one of the key pieces in electric-powered vehicle development. Nissan has kicked off tests using an X-Trail fuel cell vehicle with their new technology, which is called the SiC inverter. The inverter controls the electricity coming from the power source in electric-powered vehicles, which also improves reliability.
