摘要

本文提出了一种控制固定框架中供电两相感应电动机(TPIM)的三支路电压源逆变器(VSI)电流的新方法，该方法利用所提出的算法调制中性支路中点的电位，并使用带有优化比例和谐振(PR)控制器的两个闭环来调节电流。介绍了固定框架下常规三足VSI的两种常用电流控制策略。然后介绍了新的控制方法。计算机仿真和实验结果表明，该方法在总谐波失真(THD)、输出电流峰值超调值等方面取得了较好的性能。

A novel current control method of a three-leg inverter in the stationary frame for a two-phase AC motor

This paper proposes a novel method to control the current of a three-leg voltage source inverter (VSI) supplying a two-phase induction motor (TPIM) in the stationary frame by modulating the potential of neutral leg middle point with a proposed algorithm and using two closed loops with optimized proportional and resonant (PR) controllers to regulate the current. Two conventional current control strategies for conventional three-leg VSI in the stationary frame are presented. Then the novel control method is introduced. Both computer simulation and experiment results show the effectiveness of the proposed method in achieving better performance in terms of total harmonic distortion (THD), peak overshoot value of output current.
