<P>PROBLEM TO BE SOLVED: To provide a power conversion device that allows achievement of downsizing the device and cost reduction and allows efficient suppression of a leakage current due to parasitic capacitance. <P>SOLUTION: A power conversion device comprises an insulating-type DC-DC converter 16, an insulating-type DC-DC converter 17, and a control circuit 19. The control circuit 19 causes the insulating-type DC-DC converters 16 and 17 to operate in parallel and controls the ON/OFF operations of semiconductor switching elements 21 to 24 and semiconductor switching elements 61 to 64 so as to form a circulation path in which a leakage current flowing through parasitic capacitances to ground 103 and 105 circulates and a circulation path in which a leakage current flowing through parasitic capacitances to ground 104 and 106 circulates during the parallel operation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
