电动汽车和混合动力汽车是绿色交通和建立低碳经济的发展方向。本文提出了一种分离式变换器馈电的四相开关磁阻电动机（SRM）驱动器，以实现灵活的综合充电功能（直流和交流电源）。该电机具有一个中心抽头绕组节点、八个定子槽和六个转子极（8/6）。在驱动模式下，所开发的拓扑具有与传统的非对称桥拓扑相同的特性，但具有更好的容错性。该系统支持电池能量平衡和车载直流和交流充电。当与交流电网连接时，该拓扑具有多电平变换器的优点，可以通过改进的滞环控制来实现充电电流控制。两个电池之间的能量流通过基于其荷电状态的滞后控制来平衡。在MATLAB/Simulink中的仿真结果和150 W SRM原型上的实验验证了所提出的技术的有效性，这可能提供与重要基础设施要求相关的EV充电问题的解决方案。
Electric vehicles (EVs) and hybrid EVs are the way forward for green transportation and for establishing low-carbon economy. This paper presents a split converter-fed four-phase switched reluctance motor (SRM) drive to realize flexible integrated charging functions (dc and ac sources). The machine is featured with a central-tapped winding node, eight stator slots, and six rotor poles (8/6). In the driving mode, the developed topology has the same characteristics as the traditional asymmetric bridge topology but better fault tolerance. The proposed system supports battery energy balance and on-board dc and ac charging. When connecting with an ac power grid, the proposed topology has a merit of the multilevel converter; the charging current control can be achieved by the improved hysteresis control. The energy flow between the two batteries is balanced by the hysteresis control based on their state-of-charge conditions. Simulation results in MATLAB/Simulink and experiments on a 150-W prototype SRM validate the effectiveness of the proposed technologies, which may provide a solution to EV charging issues associated with significant infrastructure requirements.
