Abstract

트랜지스터 정류소자에 발생하는 손실을 더욱 감소시킴으로서, 높은 전력변환효율의 스위칭전원장치를 얻을 수 있다.
정류소자로서의 트랜지스터(Q2)의 베이스와 어스 사이에 구동용 트랜지스터(Q3)를 설치한다. 구동용 트랜지스터(Q3)의 베이스에는, 트랜지스터(Q2)와 플라이백 전압을 발생시키는 쵸오크코일(L1)의 접속점에서 구동신호를 입력하며, 스위칭트랜지스터(Q1)의 ON, OFF 동작에 맞춰서 트랜지스터(Q2)에 OFF, ON동작을 실시하게 한다.
트랜지스터(Q2)가 OFF상태일 때에. 콜렉터로부터 베이스방향의 전류의 누설이 방지할 수 있고, 트랜지스터 정류소자의 손실이 감소하여 스위칭전원장치의 전력 변환효율이 향상한다.
(선택도) 제2도.
