Claims (4)
- 직류전원의 양단에 두개의 트랜지스터(Q1, Q2)를 직렬로 연결하고 그 연결점에 인덕터(L1)와 캐퍼시터(C1)를 결선하고 그 양단에 형광등과 캐퍼시터(C2, C3)를 연결하며 트랜지스터(Q1, Q2)의 베이스에 전류트랜지스포머(L1)의 2차권선(N1, N2)을 연결하여 두개의 트랜지스터(Q1, Q2)가 교호로 온, 오프 되도록 하여서 된 통상의 것에 있어서, 트랜지스터(Q1, Q2)의 베이스에 인가하는 전압을 트랜지스터(TR1)로 차단시키고 트랜지스터(TR1)의 개폐는 다이리스터(SCR)로 제어하며 다이리스터가 스위칭소자에 의해 트리거되도록 하여서 됨을 특징으로 하는 형광등용 안정기의 보호회로.
- 제 1 항의 것에 있어서, 트랜지스터(Q1, Q2)의 베이스에 가되는 전압을 공급하는 2차권선(N1, N2)에 제3의 권선(L3)을 추가하여 트랜지스터(Q1, Q2)의 인가전압을 쇼트시키도록 구성시킴을 특징으로 하는 형광등용 안정기의 보호회로.
- 제 1 항 내지 제 2 항의 것에 있어서, 다이리스터(SCR)의 게이트를 트리거하는 스위칭소자가 열반응소자임(PT1)을 특징으로 하는 형광등용 안정기의 보호회로.
- 제 1 항 내지 제 2 항의 것에 있어서, 다이리스터(SCR)의 게이트를 트리거하는 스위칭소자가 전압감응소자임을 특징으로 하는 형광등용 안정기의 보호회로.
