工业应用通常需要两个（或更多）变速电力驱动器，这些驱动器必须独立控制。一个例子是中心驱动的两电机卷绕机，其中交流电机传统上由各自的三相电压源逆变器 (VSI) 供电。在过去的十年中，人们一直致力于减少多电机驱动系统中所需的电力电子器件的数量，以降低驱动器的复杂性和成本。一种此类配置由两台三相感应电机组成，使用五桥臂 VSI 供电，其中一个逆变器桥臂为两台机器共用。最近开发了一种用于五桥臂 VSI 控制的 PWM 方法，可以在两台机器之间任意分配可用直流母线电压，并且通过仿真证明了其适用于两电机中心驱动卷绕机。本文报告了该驱动系统的实际实现结果。在第一阶段，通过在空载条件下执行绕线机仿真实验来构建和测试由五腿 VSI 提供的双电机驱动器。由此证明了该配置对于实际络纱机系统的适用性。在第二阶段，构建了完整的双电机中心驱动卷纸机并提供了实验测试结果。还讨论了所分析的解决方案相对于标准解决方案的优点。
Industrial applications often require two (or more) variable speed electric drives, which have to be controlled independently. An example is a centre-driven two-motor winder, where ac machines are traditionally supplied from their individual three-phase voltage source inverters (VSIs). Over the past decade research efforts have been made to reduce the number of power electronic devices required in multi-motor drive systems in order to reduce the complexity and hence cost of the drive. One such configuration consists of two three-phase induction machines, supplied using a five-leg VSI, with one inverter leg being common to both machines. A PWM method for the five-leg VSI control, which enables an arbitrary distribution of the available dc link voltage between the two machines, has been recently developed and its suitability for application in a two-motor centre-driven winder has been demonstrated by simulation. This paper reports results of the practical realization of this drive system. In the first stage the two-motor drive supplied from a five-leg VSI is built and tested by performing the winder emulation experiments under no-load conditions. Suitability of the configuration for real winder system is thus demonstrated. In the second stage the complete two-motor centre-driven paper winder is built and results of the experimental testing are provided. The advantages of the analyzed solution over the standard one are also addressed.
