Zusammenfassung:	PURPOSE:To eliminate the flow of a large rush current to a rectifier circuit at the time of supplying a power voltage by charging a capacitor through a resistor until a predetermined voltage is obtained across the capacitor at the time of power source ON and then shortcircuiting the resistor. CONSTITUTION:When a power source voltage is supplied to an input terminal A, a smoothing condenser CD is charged through a rectifier circuit SR. A voltage is supplied from a DC/DC converter 4 to an inverter controlling circuit 2 during a period that a voltage across the condenser CD arrives at a normal value. A transistor 6 is turned OFF until the output voltage of an attenuator 7 arrives at a reference voltage V3, and a relay 5 is not energized. Accordingly, a charging current to the capacitor CD flows to a resistor RD. When the output voltage of the attenuator 7 exceeds a reference voltage V3, the transistor 6 is turned ON, and the relay 5 is energized. Thus, the resistor RD is shortcircuited by a contact (r).
