Abstract
A primary winding of a power transformer is coupled to a source of DC voltage. First and second controllable switches are coupled to the primary winding in a push-pull arrangement. A control circuit responsive to a deflection rate input signal that is synchronized with deflection circuit scanning applies a turn-off switching signal alternately to the two controllable switches during each deflection cycle. In response to the turnoff of each one of the two controllable switches, a turn-on switching signal is applied to the other switch to develop a deflection rate alternating polarity output voltage across an output winding of the power transformer. The output voltage is rectified and applied to a deflection generator to thereby energize the generator into developing scanning current in a deflection winding.
