Horizontal deflection output circuit

Abstract

Disclosed is a horizontal deflection output circuit for providing a horizontal deflection signal to a deflection yoke of a cathode ray tube to horizontally deflect electron beams in accordance with the horizontal deflection signal, the horizontal deflection output circuit having a switching transistor responsive to a horizontal output driving pulse signal applied at its base, an emitter of the switching transistor being connected to a ground terminal, a deflection yoke coupled between a first node at a collector of the switching transistor and a second node, a S-deflection distortion correcting capacitor coupled between the second node and the ground terminal, and a dampening diode and a retrace capacitor coupled in parallel between the first node and the ground terminal, the horizontal deflection output circuit comprising, a choke coil connected between a voltage source and the second node, the choke coil reducing power loss in the horizontal deflection output circuit and providing a power loss current indicative of the power loss to the deflection yoke, and a raster position correcting circuit coupled between the first node and the second node, the raster position correcting circuit providing a correction voltage to the first node for correcting a distorted raster position caused by a DC signal corresponding to the power loss current during a trace interval.
