ABSTRACT:
An AC/DC converter power supply circuit includes an AC power supply source, a first rectifier for full-wave rectifying the AC power supply source voltage, a second rectifier for further rectifying and smoothing the voltage rectified by the first rectifier, a DC/DC converter for obtaining a desired rectified and smoothed DC voltage after converting the DC voltage rectified and smoothed in the second rectifier into a second AC voltage by a high frequency inverter, and an adder for adding the second AC voltage generated in the high frequency inverter in the DC/DC converter to the full-wave rectifier voltage from the first rectifier circuit.
