ABSTRACT:
A synchronous switched vertical deflection circuit for use with a television receiver comprises first and second bidirectional switches coupled to conduct current in opposite directions. Horizontal rate energy is coupled into one end of the switches. Vertical deflection means are connected to the other end of the switches. Pulse-width modulated signals are applied to the control terminals of the switches to allow conduction of the horizontal rate energy in the vertical deflection means during selected portions of each vertical deflection interval.
