提出了一种半集中式开绕组初级永磁直线电机(HCOW-PPMLM)驱动系统，该系统需要两个独立的电压源逆变器(VSI)和一个公共电压源逆变器(VSI)来为两个开环电机供电。与传统的开绕组电机拓扑结构相比，该拓扑结构所需的半导体开关较少，可以降低系统的建设成本、系统体积、系统重量、运维成本和故障率。为了实现高性能的操作，提出了一种协同控制的拓扑结构。基于VSI最大电压最小化的原则，设计了以最大化直流母线电压利用率为目标的协同控制中的电压分配器。实验结果验证了所提出的拓扑结构和协同控制的有效性。通过变速和变负载实验，将该拓扑与传统开绕式PPMLM拓扑进行了比较。
Inthis article, a half-centralized open-winding primary permanent-magnet linear motor (HCOW-PPMLM) drives system is proposed, in which two independent voltage-source-inverters (VSIs) and one common VSI are required to supply two open-winding movers. Compared to the traditional open winding motor topology, the proposed topology requires less half-conductor switches, which can reduce the construction cost, system volume, system weight, operation and maintenance cost, and failure rate. To achieve high-performance operation, a collaborative control is proposed for the proposed topology. Based on the principle that minimizes maximum voltage of VSIs, the voltage distributor in the proposed collaborative control is designed to maximize the dc bus voltage utilization. The effectiveness of the proposed topology and the proposed collaborative control have been verified by experimental results. The proposed topology is also compared with conventional open-winding PPMLM topology by variable speed and load experiments.
