Abstract

이 발명은 파워 써플라이의 역률 보정회로에 관한 것으로서, 역률을 보정하기 위해 역률 보정용 트랜스포머와, 입력전압을 스위칭하는 두개의 스위칭용 모스 트랜지스터와, 스위칭용 모스 트랜지스터의 스위칭 동작을 제어하는 제 1 및 제 2 제어기를 구비하여 입력 전류와 동일한 주파수의 스위칭 파형으로 모스 트랜지스터를 제어하고, 쵸크코일을 트랜스포머와 일체형으로 구성함으로써, 부품의 사이즈를 소형화 시켰다. 이 발명은 모든 파워 써플라이에 적용 가능하다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power factor correction circuit for a power supply, comprising: a power factor correcting transformer, two switching MOS transistors for switching an input voltage, and a first and second controlling the switching operation of the switching MOS transistors for correcting the power factor. The MOS transistor is controlled by a switching waveform having the same frequency as the input current with two controllers, and the choke coil is integrally formed with the transformer to reduce the size of the component. This invention is applicable to all power supplies.
