Automotive Drive System (Inverter)

Generally, HEVs, PHEVs and EVs use three-phase brushless motors for electric propulsion. Because the vehicle drive battery supplies a dc current, it needs to be converted to a three-phase ac current using an inverter. A three-phase inverter, which is composed of power devices, converts dc to ac during acceleration (powering) and converts ac to dc during braking (regeneration).
