<P>PROBLEM TO BE SOLVED: To provide a driver for vehicle which is miniaturized by integrating a step-up converter and an inverter. <P>SOLUTION: The driver for vehicle comprises a motor generator MG2, a power control unit 21 for controlling the motor generator MG2, and a case for containing the motor generator MG2 and the power control unit 21. The power control unit 21 comprises a first inverter for driving the motor generator MG2, and a voltage converter for supplying the first inverter with a power supply voltage while boosting. The voltage converter includes a reactor L1. Heat is radiated from the reactor L1 by lubricant touching the reactor L1 and the case as heat transfer agent. A circulation path of lubricant is formed in the case and the reactor is arranged on the circulation path. <P>COPYRIGHT: (C)2007,JPO&INPIT |
