动态电压恢复器功率电路设计

摘要

分析了动态电压恢复器的一种拓扑结构,通过基于稳态分析的等效电路对功率电路容量、变压器变比、输出滤波器进行理论分析,同时提出开关频率、开关器件及直流母线电容的选取方法,最后给出实例计算和MATLAB仿真结果.%This paper analyzes a topology of dynamic voltage restorer, proposes the theoretical analysis for power circuit capacity, transformer ratio and output filter by the equivalent circuit based on steady -state analysis, and derives the selection method of switching frequency, switching devices and the DC bus capacitors. Finally it gives an example and simulation results by Matlab simulation software.
