Abstract

PURPOSE:To prevent the generation of a rush current when a current is fed, by inserting a switching transistor (TR) between a step-down resistance and a gate voltage supply part, and turning on the TR in accordance with the across voltage of a rush-current preventing resistance. CONSTITUTION:A commercial power source is connected between input terminals 1 and 2, and its electric power is supplied to an output capacitor 5 and a thyristor 6 connected in series through a diode rectifying circuit 4. Then, a switching TR element 15 is inserted between a step-down resistance 10 and a gate voltage supply part 11, and a TR18 is driven to turn on the TR15 in accordance with the across voltage of a resistance 8. Consequently, the thyristor 6 in an off state is turned on in the beginning of power feed, and then the element 15 is turned off. After it is turned off, a low voltage generated by a DC-DC converting circuit 7 is supplied to the supply part 11.
