ジ整流を行なうことを特徴とする電源回路。 A bridge rectifier that receives AC power to a pair of input terminals and outputs a rectified voltage from a pair of output terminals, two capacitors connected in series between the pair of output terminals, and a bridge rectifier that outputs a rectified voltage from a pair of output terminals. It comprises a voltage detection circuit for detecting a voltage, a switch means provided between one terminal of the input terminal and the connection point of the capacitor, and a drive means for opening and closing the switch means by the output of the voltage detection circuit. A power supply circuit characterized in that when the supplied voltage is 100V, the switch means is closed to perform voltage double rectification, and when the supplied voltage is 200V, the switch means is opened to perform bridge rectification.
