ABSTRACT:
A switching regulator for a television receiver, wherein a non-stable dc voltage is periodically interrupted at the horizontal frequency by a chopper and the dc voltage obtained as the output of the chopper is applied to the horizontal output circuit. Flyback pulses generated by the horizontal output circuit are integrated to generate a saw-tooth waveform, and the dc component of the saw-tooth waveform is varied in accordance with the variation of the dc voltage delivered by the chopper. The duty ratio of the chopper is changed according to the variation of the dc component of the saw-tooth waveform.
