Abstract

전자 편향을 이용하는 전자 디스플레이류의 편향 전원 공급 회로에 관한 것으로, 편향 주파수에 따라 자동적으로 출력 편향 전력을 조절함으로서, 멀티 싱크용의 디스플레이 류에도 사용할 수 있도록 한 것이다.The present invention relates to a deflection power supply circuit for electronic displays using electronic deflection, which automatically adjusts the output deflection power according to the deflection frequency, so that the display can be used for multi-sink displays.

그리고 이를 위해 입력전압이 공급되면 소정주파수를 가지고 발진하여 구형파를 생성출력하되 소정 전류 센싱신호와 피드백 신호를 받아 그의 상태에 따라 상기 구형파의 듀티를 조절하는 스위칭 제어부(10)와, 상기 스위칭 제어부(10)의 출력신호를 받아 스위칭 동작함으로서 상기 입력전압을 교류신호로 변환 출력하는 스위칭부(20)와, 상기 스위칭부(20)에 의해 변환된 교류신호를 받아 정류 평활하는 정류부(30)와, 상기 정류부(30)가 정류한 전원을 최종적으로 편향 전력으로서 출력하되 그 전류의 흐름을 센싱한 후 그에 대응된 전류센싱 신호를 생성하여 상기 스위칭 제어부(10)에 공급하는 전류 센싱부(40)와, 소정 수평편향 출력신호를 받아 그에 대응한 피드백 신호를 생성하여 상기 스위칭 제어부(10)에 공급하여 상기 스위칭 제어부(10)가 출력신호의 듀티를 제어할 수 있도록 듀티제어부(50)로 구성한다.For this purpose, when the input voltage is supplied, the switching controller 10 generates and outputs a square wave by oscillating with a predetermined frequency, and receives a predetermined current sensing signal and a feedback signal and adjusts the duty of the square wave according to its state. A switching unit 20 for converting and outputting the input voltage into an AC signal by receiving the output signal of 10), a rectifying unit 30 for rectifying and smoothing the AC signal converted by the switching unit 20; A current sensing unit 40 for finally outputting the rectified power as the deflection power by sensing the flow of the current, generating a current sensing signal corresponding thereto, and supplying the current to the switching controller 10; Receives a predetermined horizontal deflection output signal, generates a feedback signal corresponding thereto, and supplies the feedback signal to the switching controller 10 so that the switching controller 10 To control the T constitutes a duty control section 50.
