<P>PROBLEM TO BE SOLVED: To provide a power conversion apparatus which restrains noise generated by the vibration of currents flowing in a reflux diode. <P>SOLUTION: The power conversion apparatus comprises: a power conversion circuit, having a plurality of switching elements Q1 to Q6 and reflux diodes D1 to D6, which switches on/off of the plurality of switching elements Q1 to Q6 to convert input power and outputs the converted power to a load; a drive circuit 20 which drives the plurality of switching elements Q1 to Q6; and control means of controlling the power conversion circuit and the drive circuit 20. When a supply current supplied from the power conversion circuit to the load is near 0 amperes, the control means lowers a switching speed at which the switching elements Q1 to Q6 are turned on, so that it is lower than a switching speed applied in cases when the supply current is not near 0 amperes. <P>COPYRIGHT: (C)2013,JPO&INPIT |
