Abstract

본 발명은 모드 변환시에 발생하는 이상 과전류로 인해 모니터의 수평 편향회로에 결함이 생기는 것을 방지하기 위하여, 수평 편향회로의 모스 스위칭단에 모드 변환 후의 일정기간 동안 동작하는 수평 편향보호회로를 구현하고, 모드 스위칭단의 모든 모스 트랜지스터들의 게이트로 일정한 전압을 인가하여 트랜지스터들을 턴-온시킴으로써, 트랜지스터에 연결되어 있는 캐패시터를 통해 이상 과전류가 고르게 분배될 수 있도록 한 것에 관한 기술이다.The present invention implements a horizontal deflection protection circuit that operates for a predetermined period of time after the mode conversion in the MOS switching stage of the horizontal deflection circuit, in order to prevent a defect in the horizontal deflection circuit of the monitor due to the abnormal overcurrent generated during the mode conversion, The present invention relates to a method of turning on transistors by applying a constant voltage to the gates of all MOS transistors of a mode switching stage, thereby allowing an abnormal overcurrent to be evenly distributed through a capacitor connected to the transistor.
