Abstract
Presented are electric drive unit (EDU) assemblies with integrated power electronics, methods for making/operating such EDU assemblies, and motor vehicles equipped with such EDU assemblies. An EDU assembly includes an outer housing that mounts to a vehicle body. The EDU outer housing has internal motor and transmission chambers and an external cavity. A traction motor is mounted inside the motor chamber and drives one or more vehicle wheels to thereby propel the vehicle. A gear train is mounted inside the transmission chamber and drivingly connects the traction motor to the vehicle wheels. An integrated power electronics (IPE) unit, which is operable to control the traction motor, includes an IPE outer housing with a housing chassis mounted inside the external cavity, and a main housing mounted on the housing chassis to define therebetween a power electronics (PE) chamber. Multiple integrated circuit (IC) PE modules are mounted inside the PE chamber.
