Description
Claims (2)
- 플라이백 트랜스(FBT)의 출력 펄스 전압 레벨을 감지하여 수평 발진을 멈추게 하는 페일 세이프회로(10)와, 상기 페일 세이프 회로(10)의 출력으로 트랜지스터(Q2)를 구동시켜 주전원 공급용 릴레이 구동부(15)의 동작을 제어해주는 전원제어부(20)로 구성된 페일-세이프 회로 동작시 주전원 차단회로.
- 제 1 항에 있어서, 페일 세이프 회로(10)는 플라이백 트탠스(FBT)의 출력펄스를 다이오드(D1)와 콘덴서(C2)로 정류시키고 저항(R2)(R3)으로 분배시킨후 기준전압 유지용 제너다이오드(ZD1)의 구동을 제어하게 구성한 페일-세이프 회로 동작시 주전원 차단회로.
