Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power circuit capable of charging a capacitor for a power source in a short time to specified voltage and executing charging while suppressing the maximum current of a commercial power, simple in constitution, high in reliability of operation and low in cost. SOLUTION: This circuit is constituted so that the capacitor C2 for the power source is charged to the specified voltage. In this case, the energizing state of a transformer T1 for the power source to a primary side is controlled by providing a zero-cross nonarcing relay S1, and also the zero-cross nonarcing relay S1 is on/off controlled to attain the specified voltage while detecting the charge voltage of the capacitor C2 for the power source by providing a voltage detection control circuit DET.
