电动汽车（EV）为减少温室气体排放提供了可行的解决方案，因此成为研究和开发的热门话题。开关磁阻电动机是电动汽车应用的理想电机之一。为了延长电动汽车的行驶里程，在车辆上使用光伏（PV）面板有助于减少对车辆电池的依赖。基于开关磁阻电机的相绕组特性，本文提出了一种三端口变换器来控制太阳能电池板、蓄电池和开关磁阻电机之间的能量流动。提出了六种操作模式，其中四种用于驾驶，两种用于静止车载充电。在驱动模式下，实现了光伏电池最大功率点跟踪（MPPT）能量解耦控制和开关磁阻电机转速控制。在静止充电模式下，开发了并网充电拓扑结构，而无需外部硬件。当光伏板直接对蓄电池充电时，采用多段充电控制策略以优化能量利用。基于MATLAB/Simulink的仿真和实验结果证明了所提出的三端口变换器的有效性，这对提高电动汽车的市场接受度具有潜在的经济意义。
Electric vehicles (EVs) provide a feasible solution to reduce greenhouse gas emissions and thus become a hot topic for research and development. Switched reluctance motors (SRMs) are one of the promised motors for EV applications. In order to extend the EVs' driving miles, the use of photovoltaic (PV) panels on the vehicle helps to decrease the reliance on vehicle batteries. Based on the phase winding characteristics of SRMs, a tri-port converter is proposed in this paper to control the energy flow among the PV panel, battery, and SRM. Six operating modes are presented, four of which are developed for driving and two for standstill onboard charging. In the driving modes, the energy decoupling control for maximum power point tracking (MPPT) of the PV panel and speed control of the SRM are realized. In the standstill charging modes, a grid-connected charging topology is developed without a need for external hardware. When the PV panel directly charges the battery, a multisection charging control strategy is used to optimize energy utilization. Simulation results based on MATLAB/Simulink and experiments prove the effectiveness of the proposed tri-port converter, which have potential economic implications to improve the market acceptance of EVs.
