ABSTRACT:
A deflection current circuit having reduced power requirements. A switch 33 is controlled by a control circuit 71 in association with the horizontal deflection period. A switch 73 is controlled by the control circuit 72 in synchronization with the horizontal deflection period modulated by the vertical deflection period. Switch 33 is turned off in the retrace interval, and during the period in which the switch 33 is in the off-state, the switch 73 is turned off for a predetermined period. The off-period of the switch 73 is modulated by the vertical deflection period to produce greater horizontal deflection in the center of the screen.
