Abstract
An inverter includes a plurality of switching elements that convert between DC and AC power. A base plate includes a surface on which the switching elements are placed. Heat dissipating fins are provided on the opposite side of the base plate. Power is input and output through AC power terminals to and from a rotary electric machine to drive a vehicle. The terminals are electrically connected to the switching elements. A capacitor smoothes the DC power. The inverter is fixed to a case of the rotary electric machine. A rotating shaft of the rotary electric machine extends in a width direction of the vehicle. The base plate is disposed adjacent to the AC terminals in the width direction. A plurality of AC phase-terminals is sequentially arrayed perpendicular to the rotating shaft. The capacitor is disposed adjacent to the heat dissipating fins on the rear side of the vehicle.
