Beschreibung
Zusammenfassung:	The invention relates to a power conversion device. The power conversion device includes an electric leakage detection unit, a failure determination unit that outputs a pulse current for simulating and reproducing an electric leakage, and a power conversion control unit that controls conversion of power. The power conversion control unit is configured to determine a failure of the leakage detection unit on the basis of whether or not the pulse width of the pulse current as the leakage detection signal acquired by the leakage detection unit is within a predetermined range. 本发明涉及一种电力变换装置。该电力变换装置具备漏电探测部、输出用于模拟地再现漏电的脉冲电流的故障判定部、以及控制电力的变换的电力变换控制部。而且，电力变换控制部构成为根据由漏电探测部获取到的作为漏电探测信号的脉冲电流的脉宽是否处于规定的范围内来判定漏电探测部的故障。
