グレギュレータ回路。A bridge that rectifies the AC input in a self-commutated switching regulator circuit in which two switching elements connected to the DC side that rectify the AC input repeatedly turn on and off each other to take out the AC output from the secondary side of the output transformer. Connection rectifier and 1. The first and second AC input terminals connected to the input end of the rectifier, two capacitors connected in series to the output end of the rectifier, and the neutral point of these 22 capacitors connected a third AC input terminal, and controls two switching elements connected to the primary side of the output transformer based on charging and discharging of the two capacitors; and a required commercial power supply voltage is applied to the second AC input terminal, and a voltage of one-half of the commercial power supply voltage is applied to the first and third AC input terminals. Switching regulator circuit.
