Abstract

In this paper, we realize the active PFC(Power Factor Correction) system of the BF(Boost Forward) converter with the PWM-PFM control technique to control DC output voltage, to rermve the noise like hanronics at the output voltage, amd to control the input ClUTent with sinusoidal wave synchronized by the source voltage. We take the simulation and analyze the switching signal of the BF converter, input/output voltage and current, its harmonics and power factor through PSpice. And it has bren obtained harmonic reduction and efficiency improverrent.errent.

본 논문에선 BF컨버터의 능동 PFC시스템을 구성하고, 전력변화시 입력전류를 전원 접압과 동상인 정형파로 제어하여 동시에 출력전압에 포함되는 고조파 등의 잡음을 제거하고 직류 출력 전압을 제어하기 위한 PWM-PFM제어 기법을 제시하였다. 제시간 BF 컨버터의 스위칭 신호와 입·출력 전압, 전류 그리고 함유된 고조파 역률 등을 PSpice를 이용하여 시뮬레이션하고 분석하여 고조파 성분의 감소와 효율을 개선하였다.
