Abstract
Description
Claims (2)
- 모니터의 전압 안정화회로에 있어서, 수평측 FBT트랜스포머를 통한 전원과 전원단(V+)통해 입력되는 전원을 합성하는 합성수단(10)과, 상기 합성수단(10)의 출력을 평활하여 출력하는 제1평활수단(20)과, 상기 제1평활수단(20)의 출력을 기준값에 따라 비교하여 과전압시 스위칭하여 상기 평활전압을 바이패스하여 회로를 보호하는 과전압보호수단(30)과, 상기 과전압보호수단(30)을 통과한 상기 제2평활수단(20)의 출력을 검파하고 재평활하여 출력하는 제2평활수단(40)으로 구성됨을 특징으로 하는 전압안정회로.
- 제1항에 있어서, 과전압 보호수단이 상기 제1평활수단(20)의 출력을 저항(R13,R14)의 결정에 의해 결정되는 기준값에 따라 비교하여 과전압시 전계효과 트랜지스터(FET1)을 스위칭하여 상기 평활전압을 다이오드(D13)와 저항(R14)을 통해 바이패싱되도록 구성됨을 특징으로 하는 전압 안정화회로.
