摘　　要：在多电机协同运行的交流电机驱动系统中,开关器件的数量会随着电机的数量而成倍增加,这会给驱动系统的设计带来一系列的挑战。基于此,桥臂复用型电机驱动系统逐渐进入人们的研究视野。桥臂复用型电机驱动系统将一个开关器件同时连接至两相及两相以上电机绕组,可以有效降低开关器件的数量,但也带来了控制自由度降低等问题。对桥臂复用型电机驱动系统的常见拓扑进行介绍,包括五桥臂双电机系统、四桥臂双电机系统、三桥臂双电机系统和半集中式开绕组电机系统,分析了每种拓扑的结构特征以及供电特征,总结了每种拓扑结构对应控制策略的研究方向。最后,探讨和展望了桥臂复用型电机驱动系统的未来发展方向。In AC motor drive system with multi motor,the number of switching devices will increase exponentially with the number of motors.This will bring a series of challenges to the design of the drive system.Based on this consideration,the leg-sharing motor drive system has attached more attentions.The leg-sharing motor drive system connects one switching device to two or more windings.It can effectively reduce the number of switching devices,but introduce challenges including decreased control freedom.The common topologies of the leg-sharing motor drive system are summarized,including the five-leg dual motor system,the four-leg dual motor system,the three-leg dual motor system,and half centralized open winding motor systems.The structural characteristics and power supply characteristics of each topology are analyzed.Afterwards,the research directions of control strategies are summarized for each topology.Finally,the future development direction of the leg-sharing motor drive system is discussed and anticipated.
