Circuit/System Description

WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.

The drive motor generator power inverter control module (PIM) contains two motor control modules (MCMs). Each MCM operates its respective drive motor generator based upon hybrid powertrain control module (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 IGBT assembly is monitored for fault conditions.
