ABSTRACT:
A switching voltage regulator control circuit incorporating a switching device including a control electrode comprises means for sampling the output voltage of the regulator. A horizontal rate signal is combined with the sampled output voltage to provide a horizontal rate sample signal. The sample signal is compared to a predetermined reference and provides a control signal for the switching device which is applied to one input of a gating means. A second horizontal rate signal is applied to a second input of the gating means and disables it during a portion of each horizontal deflection interval.
