High-voltage traction inverter

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.

Design considerations

  • Dual electric motor architecture is more economical than one electric motor and a mechanical differential
  • In premium BEVs trend is to have separate inverters – one for each axle or one for each electric motor
  • To maximise range, inverters need to be extremely efficient yet at the same time be as small as possible, often with multiple dies per switch (4 – 8) and multiple switches per inverter cell
  • Using GaN FETs eliminates the need for a separate body diode in the inverter switches.
