摘　　要：针对传统偶数相开关磁阻电机磁路不平衡带来的转矩输出性能降低的问题,提出了一种磁路平衡控制策略。首先,分析了不同绕组连接方式下偶数相开关磁阻电机的磁场分布情况,揭示了单极性励磁是不平衡磁路产生的主要原因。然后,提出采用集成式功率变换器拓扑进行双极性励磁,保证磁路的平衡,确定了双极性励磁下功率器件的开关顺序,阐述了所提磁路平衡控制策略的工作原理和实施方法。最后,进行了仿真和实验分析,验证了所提磁路平衡控制策略能够有效增强偶数相开关磁阻电机系统转矩输出能力,同时在系统成本、算法复杂度和可靠性方面有明显的优势。Focusing on the problem of reducing torque output performance caused by unbalanced magnetic circuit of traditional even-phase switched reluctance motor,a novel magnetic circuit balance control strat-egy was proposed.Firstly,the magnetic field distribution was analyzed in different winding connection methods for even-phase switched reluctance motor,indicating that unipolar excitation is the main cause of unbalanced magnetic circuit.Then,the integrated power converter topology was adopted to realize the bi-polar excitation and ensure the balance of magnetic circuit.Next,the switching sequence of power de-vices under bipolar excitation was determined,and the working principle and implementation method of the proposed magnetic circuit balance control strategy were described.Finally,the simulation and experi-mental analysis were carried out,proving that the proposed magnetic circuit balance control can enhance the torque output performance.Also,the proposed control strategy owns significant advantages in system cost,algorithm complexity and reliability.
