摘要

与传统的三相驱动相比,由多相电机和电压源逆变器(VSI)组成的系统具有许多优点,但缺点是定子绕组中谐波电流大。本文提出了一种新的滤波方法。该滤波器的结构类似于多相感应电动机的定子。该滤波器能够有效地降低所选的谐波电流,但不受基波电流的影响。本文从理论上阐述了滤波器的原理。数值模拟和实验结果表明了该方法的有效性。

Research on Harmonics of Multiphase Induction Motors
Though a lot of advantages over the conventional three-phase drives, systems composed by multiphase motor and voltage source inverter (VSI) have a drawback of great harmonic currents in stator windings. In the paper, a novel filtering method is proposed. Construction of the filter is resembled that of the stator of a multi-phase induction motor. The filter is able to reduce the selected substantial harmonic currents effectively but free to the fundamental one. Principle of filter is expounded theoretically in the paper. Numerical simulation and experimental results show the validity of the method as well as expected.
