Abstract
This invention is directed to a circuit for permitting stable operation of horizontal deflection output, and comprises: a first parallel circuit P,composed of a first switching element,, a first damper diode,and a first resonance capacitor,; a second parallel circuit P,composed of a second switching element,, a second damper diode,and a second resonance capacitor,; a horizontal deflection yoke,connected to the second parallel circuit P,; a flyback transformer,; an integration circuit,operative to synthesize pulses from the first and second parallel circuits P,, P,to generate deflection current and to integrate inputted horizontal deflection drive signal; first and second comparison•latch circuits,for respectively comparing signal from the integration circuit,with first and second levels to latch comparison results; first and second drive circuits,for respectively driving the first and second switching elements,; and a control element for controlling the second level.
