Horizontal deflection circuits

摘要

A horizontal deflection circuit is provided in which a large retrace pulse voltage applied to a horizontal deflection yoke (4) can be taken to reduce the deflection current and which is capable of easily performing horizontal image size adjustment and distortion adjustment. A parallel connection of a switching element (11), a damper diode (12), and a resonance capacitor (13) is connected in series to a parallel connection of another switching element (21), another damper diode (22), and another resonance capacitor (23), and power is supplied from the connection point via a fly-back transformer (6). The comparison value of the retrace pulse voltages applied across both ends of the switching elements (11,21) is fed back through a switching element control circuit (40) to one of the switching elements (21) so that the deflection current of the horizontal deflection yoke (4) is controlled. <IMAGE>
