ABSTRACT:
A self-regulating horizontal deflection system with feedback indicative of the magnitude of an unregulated voltage source and of load variations to pulse width modulate the output of the horizontal oscillator is shown. Separate turn-on and turn-off drivers are transformer coupled by separate primary windings to the horizontal output transistor to optimize the driver stage and conserve power.
