Drive Motor Power Inverter Module Description and Operation: Overview
WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
The power inverter module, often referred to as the drive motor generator power inverter module, converts high voltage direct current (DC) electrical energy to 3-phase alternating current (AC) electrical energy. It is mounted directly to the transmission and is cooled with pre-mixed DEX-COOL® circulating through a cooling system that is separate from the engine cooling system. The hybrid cooling system utilizes a heat exchanger at the front of the vehicle and electric pumps to circulate the coolant. Refer to Hybrid/EV Cooling System Description and Operation .
