Harmonic Analysis of Four-phase Rectification Circuit

根据四相整流电路的工作原理,分析并推导了不同负载情况下四相整流电路中交、直流侧谐波特性,建立了四相整流电路的仿真模型并对四相整流电路在不同负载情况下的谐波特性进行了仿真分析.研究结果表明四相整流电路直流侧只存在4的倍数次谐波,提高了整流电路中最低谐波次数.对于四相整流电路的进一步理论及应用研究具有重要的参考价值.

According to the principle of four- phase rectification, the harmonic characteristic of AC/DC side of four- phase rectifier circuit have been analyzed and been deduced in the condition of different rectification load. The simulation model has been built and the simulation experiment on the harmonic characteristic of four - phase rectifier circuit has also been done. The results of study show that DC side of four - phase rectifier circuit exists only in multiples of four harmonics and it can enhance the lowest harmonic order number. The study of this paper has an important reference value for the further research of theory and application on the four- phase rectifier circuit.
