遮断することを特徴とする電源回路。 A rectifier circuit that rectifies AC voltage from a commercial power source.
a first switching transistor whose collector and emitter are connected between the rectifier circuit and a load having a capacitor coupled between both terminals; the collector and emitter are connected between the base of the first transistor and ground, and the base is connected through a bias resistor; A second switching transistor is connected to the control signal circuit, and a switching diode has one terminal connected to the load and the other terminal connected to the bias resistor. By turning on the second switching transistor and turning on the first switching transistor, the DC voltage rectified by the rectifier circuit is supplied to the load via the first switching transistor, and when the terminals of the load are short-circuited, the switching diode is switched on. A power supply circuit characterized in that the first switching transistor is turned off by turning on the first switching transistor and turning off the second switching transistor, thereby cutting off the supply of the DC voltage to the load.
