ABSTRACT:
A power supply for a video display apparatus includes circuitry that produces a pulse width modulated signal in response to the selected horizontal deflection rate. The pulse width modulated signal controls the switching of an FET through a transformer to provide a load circuit operating voltage representative of the deflection frequency. A turn-off signal for the FET is provided to a turn-off transistor from the primary winding of the transformer to insure rapid turn off of the FET.
