ABSTRACT:
A switching regulated constant voltage power supply apparatus, wherein a direct current voltage obtained through rectification and smoothing of a commercial alternate current power supply input is applied to a direct current/alternate current converting circuit implemented by a blocking oscillator such that the oscillator makes self oscillation upon turning on of the commercial alternate current power supply to provide an output from the converting circuit, the oscillator is adapted to operate in synchronism with the output from a driver circuit which is energized with the output from the converting circuit, and an error detecter is provided to detect an error fluctuation after rectification and smoothing of the output voltage from the converting circuit such that the detected output controls the converting circuit, thereby to provide a direct current constant voltage.
