ABSTRACT:
A television synchronous switched vertical deflection circuit couples energy from horizontal deflection circuit to a vertical deflection winding by means of a pair of controllable switches to form the vertical deflection current. One switch of the pair couples energy during the horizontal retrace interval and the other couples energy during the horizontal trace interval.
