Title:
DEFLECTING CIRCUIT
Document Type and Number:
Japanese Patent JP3487435
Kind Code:
B2
Abstract:
PURPOSE: To reduce the extension of vertical retracing due to a feedback signal.
CONSTITUTION: A vertical deflecting amplifier 53 has an output transistor(TR) Q1 which operates as a conductive switch for coupling a boosted source voltage with a vertical deflecting winding LV in a vertical retracing period. A feedback network (R7, R8, and C4) which bypasses the deflecting winding is coupled between the output terminal 5 and input terminal 1 of the amplifier 53 to advance the phase. A clamp diode D1 is coupled with this feedback network. The clamp diode D1 decrease the level of the feedback signal so as to postpone the point of time when the output TR Q1 begins to operate as an amplification state in a vertical retracing period.
