Special Issue: Inside the Toyota Prius: Part 5 - Inverter/converter is Prius' power broker Teardown 5/14/2007 1 comment
The inverter/converter unit (ICU) is the ringmaster of all of the electrical conversion in the Prius. The hybrid's two motor generator units have distinct roles: MG1 recharges the high-voltage (approximately 200-V) nickel metal hydride battery pack located in the rear of the car and also applies direct power to drive the MG2 assembly. MG1 additionally serves as the electric motor used to start the gas engine portion of the power train. MG2 is the primary electric drive motor when energized and
