<P>PROBLEM TO BE SOLVED: To detect electric leakage and ground fault even under a separated state from a power system. <P>SOLUTION: A power conversion apparatus 1 includes an inverter section 10 that converts DC power into AC power and a ground circuit that individually grounds a pair of output ends of the inverter section 10 through current limit elements 11, 12. Accordingly, an output end of the inverter section 10 is grounded by the ground circuit and thus electric leakage and ground fault can be detected even under a separated state from a power system. <P>COPYRIGHT: (C)2013,JPO&INPIT |
