Abstract

본 발명은 CRT의 애노드에 고전압을 전달하기 위한 고압 플라이백 트랜스포머의 출력 펄스와 거의 일치하는 펄스를 출력하는 보조 트랜스포머를 플라이백 트랜스포머의 2차측의 3차 권선에 부가하여 구성하므로써 안정된 고전압을 발생시킬 수 있으며, 이 보조트랜스포머에 축적된 에너지를 이용하여 고전압 출력을 제어하므로써 보다 안정된 고전압회로를 구현할 수 있는 효과를 가진다.

Description

고압 안정화 회로
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제4도는 본 발명에 따른 고압안정화 회로를 나타내는 회로도이다. 제5도는 본 발명에 따른 신호 파형도이다.

Claims (1)

  1. 반전단자에 플라이백 트랜스포머의 2차측 코일로부터 출력되는 플라이백펄스를 정류하여 얻어지는 전압을 인가받고, 비반전단자에 기준전압을 인가받아 두 전압을 비교하는 오차 증폭기와; 상기 오차 증폭기의 출력에 의해 변조되고 동시에, 글라이백 펄스에 동기되는 출력신호를 발생하는 펄스폭 변조회로와; 상기 펄스폭 변조회로의 출력신호에 따라 스위칭 동작하는 스위칭부와; 상기 스위칭부의 동작에 따른 신호를 1차측 코일에 인가받고, 2차측 코일이 상기 플라이백 트랜스포머에 병렬로 접속되어, 상기 플라이백 트랜스포머의 출력펄스와 거의 일치하는 펄스를 출력하는 보조트랜스포머를 포함하는 고압 안정화 회로.
