Plug-in hybrid electric vehicles (PHEVs) possess the merits of low carbon emissions, high fuel efficiency, and long driving mileage, and thus attract more and more attention. This article presents an integrated switched reluctance motor (SRM) powertrain topology for PHEVs, which owns multiple driving and battery-charging functions with less power electronic devices than traditional topology. In motor driving mode, four driving modes are achieved according to the road conditions. Motoring and braking operations can be successfully implemented. For battery-charging mode, three charging modes are implemented without extra battery chargers. A three-channel interleaved boost converter with power factor correction (PFC) capability is constituted by utilizing the SRM windings and integrated converter circuit to charge the traction battery from the grid. An integrated half-bridge isolation dc/dc converter is employed to charge the auxiliary battery from the generator or traction battery. A proof-of-concept prototype platform is built and experiments are carried out on a three-phase 12/8 poles SRM to verify the effectiveness of the proposed integrated drive topology and the corresponding control schemes.

具有多种驱动和车载充电功能的插电式混合动力电动汽车的集成 SRM 动力总成拓扑结构

插电式混合动力汽车（PHEV）具有碳排放低、燃油效率高、行驶里程长等优点，越来越受到人们的关注。本文介绍了一种用于 PHEV 的集成开关磁阻电机 (SRM) 动力总成拓扑，该拓扑具有多种驱动和电池充电功能，与传统拓扑相比，电力电子设备更少。在电机驱动模式下，根据路况实现四种驱动模式。可以成功实施电动和制动操作。对于电池充电模式，无需额外的电池充电器即可实现三种充电模式。具有功率因数校正 (PFC) 能力的三通道交错升压转换器是通过利用 SRM 绕组和集成转换器电路从电网为牵引电池充电而构成的。集成的半桥隔离 DC/DC 转换器用于从发电机或牵引电池为辅助电池充电。建立了一个概念验证原型平台，并在三相 12/8 极 SRM 上进行了实验，以验证所提出的集成驱动拓扑和相应控制方案的有效性。
