本文介绍了利用空间矢量调制（SVM）对五腿逆变器（5LI）供电的两台三相异步电动机（IMs）进行独立矢量控制的方法和实验结果。利用支持向量机可以自由选择切换次数。支持向量机也可以减少切换次数。但是，由于5LI的电路配置是独特的，通常的支持向量机技术在三电压源逆变器（3-VSI）中为电机输出电压，不能应用于5LI进行独立驱动。因此，需要新的支持向量机技术。本文介绍了支持向量机技术在5LI中的应用。实验的指令是调速驱动和常速驱动。实验结果证明，支持向量机的5LI可以通过矢量控制独立驱动两个IMs。
This paper presents the methodology and the experimental results of the independent vector control of two three-phase induction motors (IMs) fed by a five-leg inverter (5LI) with space vector modulation (SVM). We can select freely the switching count by using SVM. SVM can also reduce the switching count. But normal SVM techniques to output voltages for motor in three-voltage source inverter (3-VSI) cannot be applied to the 5LI for independent driving because the circuit configuration of 5LI is unique. Therefore, the new SVM technique is needed. This paper shows the SVM technique for 5LI. The commands of the experiments are the adjustable speed drive and the normal speed drive. The experimental results are proved that 5LI with SVM can drive two IMs independently by vector control.
