摘要

本文研究了一种可在连续和断续导通条件下工作的Cuk变换器的动态功率因数校正。它用于克服二极管桥式整流器从交流源引出非正弦电流而使输入功率因数很差的影响。用二极管桥式整流器、二极管桥式整流器加cuk变换器分析了交流电源输入电流的THD和输入功率因数。在MATLAB/Simulink中对该系统进行了CCM和DCM两种模式的仿真。采用PIC微控制器实现了cuk变换器的硬件样机，以辅助动态功率因数校正。

Dynamic power factor control using multi-model operation of Cuk converter

This paper deals with dynamic power factor correction using Cuk converter that can be operated in continuous and discontinuous conduction. It is used to overcome the effect of diode bridge rectifier that draws non-sinusoidal current from the AC source and makes the input power factor very poor. The THD of the input current at the AC mains and input power factor are analysed with the diode bridge rectifier, diode bridge rectifier with cuk converter. The proposed system is simulated in MATLAB/Simulink for CCM and DCM modes. A hardware prototype of the cuk converter is implemented using PIC microcontroller to assist in dynamic power factor correction.
