Abstract

스위치-모드 전원 회로에서, 스위치가 긴주기(또는 매우 빈번하게)동안 전원 회로에 접속된 부하에 따라서 도통되므로써, 변압기가 충분한 에너지를 2차 권선측에 전송하여 출력 캐페시터를 충분하게 충전시키도록 한다. 변압기 자체에 저장된 모드 에너지를 2차 권선측에 공급시키기 위하여, 탈자기 검출 회로는 변압기의 탈자기화 여부를 검출한다. 만일 부하가 감소되면(예를 들어, 예비 동작시에), 스위치의 온-타임은 감소된다.
그러나, 이 온-타임은 전원 회로가 더이상 적절하게 기능하지 못하도록 최소값이 되어야만 한다. 전원 회로를 정상 동작 및 저부하 상태에서 효율적으로 동작시키기 위하여, 전원 회로의 제어회로는 적어도 두가지 모드, 즉, 제1모드(예비동작) 및 가변 주파수인 제2모드(정상 동작)을 갖는데, 상기 제1모드에서 제어펄스는 고정된 주파수로 스위치에 인가되고, 상기 제2모드에서 제어 펄스의 주파수는 가변되고 필요한 경우 탈자기 신호는 변압기가 완전히 탈자기되지 않았을때 스위치에 인가되는 제어 펄스를 지연시킬 수 있다.
