Abstract of the Disclosure A horizontal deflection system driven auxiliary supply for a television receiver has as a rectifying device an integrated thyristor-rectifier (ITR). When the deflection system is operating under normal conditions the rectifier portion of the ITR provides direct operating current through conventional filter circuitry to other receiver circuits, such as the vertical deflection system whose performance is essential to the production of a viewable display. When the horizontal deflection system generates excessive voltage which results in an undesirable increase in the picture tube anode voltage derived from the deflection system, the peak cathode voltage of the …
