ABSTRACT:
A high voltage limiting circuit for a television receiver employs a negative pulse sample from a tertiary winding on a flyback transformer as a measure of high voltage. When the amplitude of the negative pulse sample exceeds a predetermined value, indicating excessive high voltage, a limiting circuit applies a voltage to an automatic frequency control input of a horizontal oscillator to increase the frequency of the horizontal oscillator. The increased frequency limits further increase in high voltage.
