三相变流器PFC和APF组合实现研究

Research on Three Phase Converter Working as both PFC and APF

三相变流器在有源电力滤波器(APF)和功率因数校正(PFC)中有着广泛的应用。本文在建立三相变流器数学模型的基础上,分析了主电路参数对系统稳定性的影响。结合分析现有的三相变流器作为PFC和APF的主电路参数选择方法,提出了新的设计方法,以适用于三相变流器同时作为APF和PFC的场合。文中给出了相关的实验结果。

Three phase PWM converter are widely used in APF and PFC.This paper analyzes the influence of main circuit parameters on three phase converter system stability based on its mathematic model.The selection meth-ods of APF and PFC parameters are summarized,and a new design method is proposed in order to adapt three phase converter to working as both APF and PFC function.Some experimental results are given to ensure the analysis.
