Abstract

An AC-DC converter is disclosed which is so designed as to realize an improved power factor and thereby minimize generation of voltage distortion and higher harmonies in power supply line, without making the circuit arrangement complex and bulky. A step-down DC-DC converter is connected to an output side rectifier, and the arrangement is made such that the output current of the rectifier is permitted to flow only during a time period when the output voltage of the rectifier is higher than the voltage at an output capacitor of the DC-DC converter.
