摘 要：

The present invention relates to a power conversion device. It is an object of the present invention to limit an inrush current while reducing overall weight and volume of the device even under a high rated power. In order to achieve the object, one and the other ends of an initial charging circuit (6) having a DC power source (16), a switch (18) and a diode (19) connected in series are connected to an inductive load (50) and a lower potential source line (NN), respectively in a power conversion device. The initial charge controller unit (70) turns ON and OFF one switching element (24) of the power conversion device repeatedly during an initial charging operation prior to the normal operation. As a result, a charging current (ICHG) flowing through the initial charging circuit (6) is supplied to a capacitor (12) through the inductive load (50)

repeatedly. After the capacitor (12) is
