Abstract

무정전 전원장치에 있어서, 정류부와 축전지부 사이에 반도체 스위치, 다이오드 및 평활용 콘덴서로 구성된 역률제어기를 부가하여 입력전압을 필요한 만큼 승압시킨후 펄스폭 변조방식에 의해 인버터로 직류전압을 교류전압으로 변환하는 디지탈 승압형 역률 제어기를 구비한 무정전 전원장치이다.In the uninterruptible power supply, a power factor controller composed of a semiconductor switch, a diode, and a smoothing capacitor is added between the rectifying unit and the battery unit to boost the input voltage as necessary, and then convert the DC voltage into an AC voltage by an inverter by a pulse width modulation method. It is an uninterruptible power supply having a digital step-up power factor controller.
