Claims (2)
- 상용전원공급스위치와, 상기 상용전원공급스위치에 의해 전달되는 상용교류전원(110V-220V)을 직류전원으로 변환하는 정류부와, 상기 정류부에 의한 직류전원으로 충전하여 평활전압을 출력하는 평활수단과, 전원차단시 상기 평활수단의 평활전압에 대한 방전시간을 길게하여 전원 재투입시 과도한 돌입전류를 방지하고, 정상 운전시 제어전원을 출력하는 저전압차단수단과, 상기 저전압차단수단의 제어전원에 의해 전체 제어시스템에 전원을 공급하는 전원회로부와, 상용전원의 최초 돌입전류를 방지하는 부성온도특성(NTC)을 갖는 소자를 포함하여 이루어짐을 특징으로 하는 돌입전류 차단회로.
- 제1항에 있어서, 저전압차단수단은 평활전압이 제너전압보다 크거나 작음에 따라 전류를 차단하고 흘리게하는 제너다이오드와, 상기 제너다이오드에 의해 동작하는 제1,제2트랜지스터와, 상기 제너다이오드에 차단될 경우 충전된 평활전압에 대한 방전시간을 연장하는 발광다이오드를 포함하여 이루어짐을 특징으로 하는 돌입전류 차단회로.
