TRACTION MOTOR INVERTER : System Description

- The traction motor inverter controls the traction motor based on the drive command signal transmitted by
HEV system CAN from the HPCM.
- Traction motor inverter converts DC power from Li-ion battery to AC power, and drives traction motor accurately based on resolver detection signal and current sensor detection signal.
- At deceleration, traction motor is used as generator. It converts kinetic energy generated by rotary motion of tires (AC power) to electric energy (DC power) and charges Li-ion battery.
- If malfunction is detected, the system enters fail-safe mode. Fail Safe.
