摘要

本文提出了一种分析变频供电六相交流电动机输出电流纹波的方法。基于分析方法，研究了采用PWM逆变器时的最优相位差。在产生气隙磁通的谐波组中，产生最小电流纹波的相位位移是最优的。经分析，最优相位位移为60°。这一结果得到了实验结果的支持。

Analysis and minimization of output current ripple of inverter-fed six-phase AC motors

An analysis method for output current ripple of inverter-fed six-phase AC motors is presented in this paper. Based on the analysis method, this paper investigates the optimal phase displacement when PWM inverter is used. The optimal phase displacement is the one that produce minimum current ripple in the harmonic sets for air gap flux production. Based on the analysis, the optimal phase displacement is 60°. This result is supported by experimental results.
