With both battery electric vehicles (BEV) or plug-in hybrid electric vehicles (PHEV), transferring the stored energy from the high-voltage (400 / 800 V) battery to the electric motors used to drive the wheels is the job of the high-voltage traction inverter. Traction inverters currently come in all shapes and sizes, ranging from 50 kW up to more than 500 kW with currents of several hundred amps. So safe and efficient DC to AC conversion is critical. In addition a small efficient traction inverter using GaN FETs can help eliminate the high-frequency whine associated with many battery powered vehicles.
