Abstract
Description
Claims (1)
- 전원회로(30)의 출력전원이 트랜지스터(Q1), 접지콘덴서(C3) 및 코일(L1)을 통해 수평출력회로(60)에 공급되고, 상기 트랜지스터(Q1)에서 출력되어 저항(R9) 및 가변저항(VR2)에서 검출되는 전압 및 핑큐션회로(40)의 출력전압에 의해 오피앰프(OP2)의 출력전압이 제어되어 트랜지스터(Q2)의 도통율이 제어됨에 따라 상기 트랜지스터(Q1)의 도통율이 제어되는 모니터의 수평회로에 있어서, 상기 가변저항(VR2)의 가변단자는 오피앰프(OP3) 및 저항(R8)을 통하고 상기 핀큐션회로(40)는 콘덴서(C2)를 통해 상기 오피앰프(OP2)의 마이너스 단자에 공통접속하여, 그 접속점을 저항(R7)을 통해 그 오피앰프(OP2)의 출력단자에 접속하고, 수평동기신호단(Hsync)은 주파수/전압콘버터(10), 오피앰프(OP1), 저항(R1) 및 가변저항(VR1)을 통해 상기 오피앰프(OP2)의 플러스단자에 접속함과 아울러 전원단자(Vcc)를 저항(R2)를 통해 콘덴서(C1) 및 제너다이오드(ZD1)에 접속한 후 그 접속점을 다이오드(ZD1)를 통해 상기 저항(R1)를 통해 상기 저항(R1) 및 가변저항(VR1)의 접속점에 접속하여 구성된 것을 특징으로 하는 모니터의 수평 편향 진폭 자동 보정회로.
