本文分析了双反星型整流电路工作原理及输出特性。采用MATLAB/Simulink工具建立双反星型整流电路模型,进行了无平衡电抗器存在时的输出测试;存在平衡电抗器时的电阻性、电感性输出测试。针对输出,进行了谐波仿真分析,结果表明,输出电压值、直流侧最低次为六次谐波,与理论分析相一致,为该电路在大电流直流供电领域的应用提供依据。

The working principle and output characteristics of double anti-star rectifier circuit are analyzed. Using MATLAB/Simulink tool to set up a dual anti-star rectifier circuit model, the output test of the unbalanced reactor was carried out and the resistivity and inductive output test when there is a balanced reactor. According to the output, the harmonic simulation analysis was carried out. The results show that the output voltage, the lowest six harmonics on the DC side are consistent with the theoretical analysis, and provide a basis for the application of this circuit in the field of high current DC power supply.
