Drive Motor Generator Power Inverter Module

Overview 

The power inverter module contains 3 motor control modules and the hybrid powertrain control module. Two of the motor control modules operate their respective drive motor generators based upon power inverter module commands. The third motor control module 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. All four modules are flash-programmable micro-processors.
