摘　　要：与传统开关磁阻电机相比,轴径向混合磁通开关磁阻电机具有功率密度高、转矩性能好等优点。传统的不对称半桥功率变换器无法实现新型轴径向混合磁通开关磁阻电机在轴向定子、径向定子、轴径定子串联三种工作模式之间的切换运行,为此,本文提出了一种实现三种模式在线切换的新型功率变换器。首先,介绍了新型功率变换器的拓扑结构和三种工作模式下的运行策略;其次在MATLAB/Simulink中建立新型功率变换器仿真模型进行仿真分析;最后在一台三相12/10/12结构轴径向混合磁通开关磁阻电机进行了实验测试,验证了新型功率变换器驱动系统的有效性。Compared with the conventional switched reluctance motor(SRM),axial-radial flux switched reluctance motor(ARFSRM)have the advantages of high power density and good torque performance.Conventional asymmetric half-bridge(AHB)power converter is unable to realize the switching operation of the ARFSRM between three modes of operation:axial stator mode,radial stator mode,and the mode of axial and radial stators connected in series.To this extent,a novel power converter was proposed in this paper to realize the online switching of the three modes.Firstly,the topology of the novel power converter and the operation strategies in three operation modes were introduced.Secondly,the novel power converter model was established in Matlab/Simulink for simulation and analysis.Finally,experimental tests were carried out in a three-phase 12/10/12 ARFSRM,which verified the validity of the novel power converter drive system.
