摘要

通过对传统Boost型功率因数校正(PFC)电路电流滞环控制方法中开关时间的分析

提出了一种简单的控制方案.将电路的逻辑控制分为两个相对独立的部分

分别利用恒导通时间控制技术和平均电感电流信号来确定电感电流的上限和下限

即可实现PFC.实验电路用一只RC低通滤波器来代替传统控制方法中的模拟乘法器和输入电压检测环路

测试获得了接近1的功率因数.

Abstract

Based on the analysis of the switch time in the traditional Hysteretic-Current-Loop-Control Boost Type Power-Factor-Correction(PFC)circuit

this paper proposes a simple control mode.To achieve PFC

this mode divides the logical control into two parts

then it determines the prescribed maximum inductor current and the minimum inductor current respectively by constant turn-on time technology and the average inductor current signal.In experimental circuit

a RC low-filter replaces the multiplier and the input voltage sensor of traditional mode and the measurement gets near unit power factor.
