Patent ID: 8643235

Claim:
A drive device for a vehicle comprising: a rotating electric machine generating drive force; and a power control unit provided integrally with said rotating electric machine for controlling said rotating electric machine, said power control unit including a low-voltage circuit section to which a relatively low voltage is applied, a high-voltage circuit section which is located at a rear side of the vehicle relative to said low-voltage circuit section and to which a relatively high voltage is applied, and a cooling plate located between said low-voltage circuit section and said high-voltage circuit section in a longitudinal direction of the vehicle for cooling said high-voltage circuit section, wherein said high-voltage circuit section includes an inverter converting between a DC voltage and an AC voltage between said rotating electric machine and a battery, and a converter boosting and down-converting a voltage, the converter including a smoothing capacitor smoothing the voltage after being boosted, and said low-voltage circuit section includes a controller sending control signals to said inverter and said converter.
