Abstract
A vertical deflection distortion correction circuit, wherein there are provided a vertical deflection output circuit, a damping circuit, a vertical deflection yoke and a resonance circuit. A current is resonated in the resonance circuit, and on the other hand, a vertical deflection current is derived from the vertical deflection output circuit and supplied to the vertical deflection yoke. Then, the resonated current is superimposed on the vertical deflection current. The superimposed vertical deflection current is finally supplied to the vertical deflection yoke. The resonance circuit is constructed of an LC parallel circuit and a switching element circuit. The switching element circuit is compose of either FETs, or thyristors.
