Claims (3)
- 주전원부의 1차추에 배치된 과부하 보호회로 및 전원을 분리하는 결합소자를 통해 1차측에 배치된 스위칭 트랜지스터를 부하에 의존하는 펄스폭 변조에 의해 구동시키는 2차측의 레귤레이팅회로를 가진 수상기의 전원분리를 위한 전력주파수로 동기화된 조합회로를 가진 텔레비젼 수상기의 전원회로에 있어서, 조합회로에 의해 발생된 2차전압은 비교기(32)의 한 입력에 인가되고 상기 비교기(32)의 다른 입력에는 조합회로와 무관하게 발생된 비교전압이 인가되며 비교기(32)는 비교기 입력에서 발생된 2차전압의 강하에 의해 1차 측의 보호회로의 응답시 2차측의 보호회로에 대한 비교기출력에 신호를 공급하고, 상기 보호회로는 스타팅회로(24)를 통해 강제 휴지기후에 조합회로의 구동을 위해 펄스폭 변조기를 다시 접속시키는 것을 특징으로 하는 텔레비젼 수상기의 전원회로.
- 제1항에 있어서, 스탠-바이전압을 발생시키기 위해 조합회로와 무관한 전압이 주전원부로 부터 인출되는 것을 특징으로 하는 텔레비젼 수상기의 전원회로.
- 제1항에 있어서, 예정된 강제휴지기를 삽입하면서 임의로 정해진 수만큼 접속시도가 이루어지지 않으면 조합회로를 더이상 접속시키지 않는 카운팅 회로가 설치되는 것을 특징으로 하는 텔레비젼 수상기의 전원회로.
