Abstract
Description
Claims (3)
- 펄스폭변조에 의한 스위칭 작용으로 변압기를 구동시킴으로써 입력되는 교류 전압에 대해 복수개의 변환된 직류 출력전압을 얻으며, 상기 출력전압의 변동을 에러전압 검출/궤환부로 검출하고, 이에 따른 펄스폭을 변화시킴으로써 항상 일정한 출력전압을 유지하는 스위칭모드 전원공급장치에 있어서,상기 출력전압을 입력받는 제너다이오드와; 설정전압 출력부와; 상기 출력전압과 상기 설정전압을 비교하여, 상기 출력전압이 상기 설정전압보다 더 큰 경우 스위칭 펄스의 듀티가 0이 되도록 하는 제어신호를 상기 에러전압 검출/궤환부로 출력하는 마이크로 컴퓨터를 갖는 과전압 보호회로를 포함하는 것을 특징으로 하는 스위칭모드 전원공급장치.
- 제 1 항에 있어서,상기 설정전압은 적어도 둘 이상이며,둘 이상의 상기 설정전압을 선택할 수 있는 스위치를 더 포함하는 것을 특징으로 하는 스위칭모드 전원공급장치.
- 제 1 항에 있어서,상기 제너 다이오드는 상기 출력전압의 허용 최대 전압에서 도통되는 항복전압을 가지는 것을 특징으로 하는 과전압 보호회로를 갖는 스위칭모드 전원공급장치.
