本文介绍了由四腿逆变器（FLI）供电的两台三相异步电动机（IMs）独立驱动特性的实验结果。FLI是一个可以独立驱动两个三相交流电机的逆变器。逆变器由四个支腿和两个串联的电容器组成。两台电机的U相和V相分别连接在每条支路上，而两台电机的W相连接在双电容的中性点上。三相电压源逆变器的脉宽调制技术由于只需要调制两相，不能直接应用于FLI。然后，对双电容的中性点电位和逆变器输出电压进行了分析。接下来，还展示了FLI中的调制技术。实验结果验证了两种与IM无关的驱动器的特性和分析结果的有效性。
This paper presents the experimental results of the independent drive characteristics of two three-phase induction motors (IMs) fed by a four-leg inverter (FLI). The FLI is a single inverter that can drive two three-phase ac motors independently. The inverter consists of four legs and two capacitors connected in a series. The U and V phases of both motors are connected in each leg, respectively, whereas the W phase of both motors is connected in the neutral point of two-sprit capacitors. The pulsewidth modulation technique in three-phase voltage source inverter is not directly applicable for the FLI because only two phases must be modulated. Then, this paper also analyzes about the neutral point potential of two-sprit capacitors and inverter output voltage. Next, the modulation technique in the FLI is also shown. The experimental results demonstrate the characteristics of two IM independent drives and the validity of those analytic results.
