ABSTRACT:
In a power supply circuit useful for a horizontal deflection circuit in a television receiver, there is provided a voltage-controlled semiconductor element, for example, such as silicon controlled rectifier, in order to stabilize effectively the output power voltage. The silicon controlled rectifier is switched between its OFF and ON states in response to two kinds of pulses: flyback pulses occurring within the television receiver and newly produced control pulses having relative phases with respect to the phase of the flyback pulses which relative phases differ depending upon variations in the input power voltage. Current flow through the silicon controlled rectifier charges a capacitor connected thereto which in turn provides the stabilized output voltage to the horizontal deflection circuit.
