본문에 상술하고 도면에 예시한 바와 같이 교류 전원을 정류하여 직류로 사용하는 전가 기기에 있어서 그 입력 역률을 개선할 목적으로 교류 전압을 정류하여 맥류 전압을 얻은 후 그에 비례하는 입력 전류가 흐르도록 일정한 시비율로 스윗칭 소자를 구동하여 트랜스 포머의 1차측 인덕턴스에 에너지를 저장한 다음 2차측을 통하여 필터캐패시터에 전달함으로써 직류 출력 전압을 얻음과 동시에 입력 역률을 고역률로 하도록 하는 고역률 정류회로.As described in the text and illustrated in the drawings, in an electronic device that rectifies an AC power source and uses it as a direct current, a rectifying AC voltage is obtained to obtain a pulse current after rectifying the AC power to improve the input power factor. A high power factor rectifier circuit that drives the switching element at a rate and stores energy in the primary inductance of the transformer, and then transfers it to the filter capacitor through the secondary side to obtain a DC output voltage and make the input power factor high. 제1항에 있어서, 스윗칭 소자의 시비율을 제어하여 입력 전압보다 높거나 낮은 일정한 직류 출력 전압을 얻도록 하는 고역률 정전압 회로.2. The high power factor constant voltage circuit of claim 1, wherein the ratio of the switching elements is controlled to obtain a constant DC output voltage that is higher or lower than the input voltage. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
