Drive Motor Power Inverter Module Description and Operation: Overview

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 under hood below the air inlet grill panel 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 .
