P1afe Saturn Description

The drive motor generator Power Inverter Control Module (PIM) contains two Motor Control Modules (MCMs) and the Hybrid Powertrain Control Module (HPCM). Each MCM operates its respective drive motor generator based upon HPCM commands. Each MCM controls the speed, direction and output torque of its respective drive motor generator through the sequencing actuation of high current switching transistors called insulated gate bipolar transistors (IGBTs). Each drive motor generator operates utilizing 3 phase Alternating Current (AC) electricity. Each IGBT operates a single phase of the drive motor generator. Each phase is individually identified as U, V and W. Each MCM monitors the current of each phase in order to detect PIM overcurrent conditions.

When high voltage is enabled, each MCM supplies its respective drive motor generator with just enough current to energize the magnetic field even when no motor generator torque is required. The MCM monitors the phase current sensors for this minimal current to ensure the drive motor phase circuits are functioning properly.
