摘要
通过对电压型不控整流电路拓扑结构的理论分析及仿真分析,比较每一种拓扑结构的输出电压波形、输出电压平均值、网侧电流谐波含量,总结电压型不控整流电路的优缺点。同时对电路中滤波电容的能量耗散、容值大小的选择进行了仿真分析,阐述拓扑结构中滤波电容大小选择的重要性。
Based on the theoretical analysis and the simulation analysis of the voltage-typed non-controlled rectifier circuit,analyzes and compares the output voltage waveform,the mean output voltage value and the at-side current＇s harmonic content of diftrent circuits,and then summarizes the advanlages and disadwmtages of each circuit. Also analyzes the energy dissipation of the fiher capacitor and the, seleet of the capacitor size,and then illustrates the imporlance of the capacitor size.
