Abstract
Description
Claims (1)
- 트랜스(TS)에 인가되는 110/220V의 전원을 절환하려 부하(3)에 공급하는 회로에 있어서, 상기 트랜스(TS) 이차측코일(L1)의 출력전압을 반파정류 하는 다이오드(D1,(D2)와, 상기 다이오드(D1)에서 반파정류된 전압을 저항(R1)과 콘덴서(C2)의 시정수에의해 지연시키는 지연회로(1)와, 상기 트랜스(TS) 이차측코일(L2) 출력전압을 반파 정류하는 다이오드(D3)와, 상기 지연회로(1)와 트랜스(TS) 이차측코일(LS)에서 인가된 신호에 의해 트랜지스터(Q3) (Q4)가 스위칭하는 인버터회로(2)와, 상기 인버터회로(2)의 트랜지스터(Q4)도통시 "턴온"되어 110V의 전원을 부하(3)에 공급하는 트랜지스터(Q1)와, 상기 인버터회로(2)의 트랜지스터(Q3) 도통시 "턴온"되어 220V의 전원을 부하(3)에 공급하는 트랜지스터(Q2)를 구비함을 특징으로 하는 110/220V 자동전압 조절회로.
