Circuit/System Description

The power inverter module, often referred to as the drive motor generator power inverter module, contains two motor control modules and the hybrid/EV powertrain control module 1. The motor control modules operate their respective drive motor generator based upon drive motor generator power inverter module commands. The hybrid/EV powertrain control module 1 controls the auxiliary transmission fluid pump motor. The hybrid powertrain control module and the motor control modules share the power inverter module ignition voltage circuit, battery voltage circuits and chassis ground.
