特徴とする電源回路。[Claims for Utility Model Registration] The control unit includes a rectifying means for converting input AC into a DC power source and a control unit, and the control unit converts the DC power by a comparison signal between the magnitude of the current supplied to the load and a reference voltage. In a power supply device that forms a DC current of a predetermined level from a power source and supplies it to a load, a voltage comparator that compares a divided voltage of the DC voltage applied to the load and a divided voltage of the DC voltage applied to the control unit; Controlled by the output signal of the voltage comparator, when the divided voltage on the load side exceeds a predetermined value with respect to the divided voltage of the control section, the DC voltage applied to the control section is lowered to a voltage corresponding to the predetermined value. A power supply circuit comprising: a voltage control section for lowering the voltage to .
