Hitachi starts mass production of 800-volt EV inverter

Hitachi Automotive Systems is starting mass production of its 800-volt, high-output EV inverter. The company says that, thanks to its strong cooling performance, the new inverter delivers twice the voltage and 2.7 times the power density of previous generations. Most EVs are based on a 400-volt system, so in order to increase driving range, additional… Read more »

Cree to supply SiC semiconductors to ZF for electric drives

Cree, a US maker of silicon carbide (SiC) semiconductors, has partnered with German parts supplier ZF Friedrichshafen to supply SiC semiconductors for electric drives. ZF will initially use Cree’s technology to fulfill pre-existing orders from several auto manufacturers for silicon carbide-based electric drives, but ZF hopes to make silicon carbide electric drivelines available to the… Read more »
