Abstract: 영전압 스위칭 전원 장치의 주 스위칭 트랜지스터가 도통된 때, 전압(VR7)은 상기 트랜지스터와 직렬로 결합된 전류 감지 저항 내에 나타나게 된다. 전류 감지 저항 내의 전압은 제어 회로(Q2, Q3)의 비교 회로(Q3)의 제1 입력(베이스)에 결합된다. 비교기의 제2 입력(이미터)은 전원 장치의 출력 전압(IDOUT2)에 따라 변하는 전압(VC6)을 나타내는 커패시터(C6)에 결합된다. 트랜지스터의 주어진 도통 간격 동안, 비교기(Q3)는 전류 감지 저항의 전압과 커패시터 전압 사이의 차이에 따라 트리거 된다. 비교기(Q3)의 출력은 전류 펄스마다 트랜지스터의 즉각적인 턴오프를 제어하기 위해 트랜지스터의 베이스에 결합된다. 과부하 상태 하에서 트랜지스터가 턴오프된 때, 역콜렉터 전류는 트랜지스터의 베이스-콜렉터 접합을 통해 흐른다. 역콜렉터 전류는 트랜지스터의 순방향 도통 동안, 전류 감지 저항 전압에 대하여 반대 극성인 전압(음)을 전류 감지 저항 내에 생성한다. 감지된 역전류에 의해 생성된 전압은 다이오드(D10) 스위치를 턴온하고 피크 순방향 콜렉터 전류를 감소시키는 방법으로 제어 회로의 비교기에 결합된 커패시터를 충전한다. 이에 의해, 보호 없이 발생될 수 있는 값에 비례하여 트랜지스터 내의 피크 순방향 전류를 감소시킨다.
