する電源回路。In the power supply circuit of a television receiver, a silicon-controlled rectifier is controlled on/off based on the horizontal pulse obtained from the horizontal output quadrance and the output pulse obtained from the error detection phase control circuit to obtain a stabilized DC output voltage. A DC voltage obtained by rectifying and smoothing the horizontal output pulse obtained from the horizontal output quadrance is superimposed on the stabilized DC output voltage and supplied to the error detection phase control circuit, and the DC output voltage is adjusted according to an increase or decrease in the high voltage load current. A power supply circuit characterized by changing the
