<P>PROBLEM TO BE SOLVED: To reduce a ripple component of a current flowing to a reactor to thereby control vibration of the reactor. <P>SOLUTION: A control unit 18 controls a driving side voltage VH of a voltage conversion circuit 12 based on a vehicle traveling state and drive operation. The control unit 18 determines whether the driving side voltage VH read from a voltmeter V is larger than VL1+VL2. Here, the voltage VL 2 is a voltage larger than the voltage VL1. When the driving side voltage VH is larger than VL1+VL2, the control unit 18 sets the power supply side voltage VL to the voltage VL1 by the control of DC voltage source 10. Meanwhile, when the driving side voltage VH is the VL1+VL2 or less, the power supply side voltage VL is set to the voltage VL2 by the control of the DC voltage source 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
