插电式混合动力电动汽车（PHEV）在减少温室气体排放方面提供了很大的希望，因此是研发的焦点。现有的车载充电能力是有效的，但需要使用多个电源转换设备和电源转换器，从而降低可靠性和成本效率。本文提出了具有集成充电功能（包括内燃机和电网充电）的新型三相切换不情愿（SR）电动机驱动器。传动系统中的电能流由电源电子转换器控制，其功率开关设备和磁性设备较少。它允许在不同的操作模式下，发动机发生器，电池和SR电动机之间的所需能量转换。开发了电池充电技术，可在电动机驾驶模式和停顿充电模式下运行。在磁化模式下，机器的相绕组通过直流链接电压通电。功率转换器和机器相绕组由三相继电器控制，以实现AC-DC整流器的使用。电源转换器可以用作降压型型或降压型DC-DC转换器，用于充电电池。模拟导致MATLAB/SIMULINK和3 kW SR汽车的实验验证了拟议技术的有效性，该技术可能具有重大的经济影响并改善了PHEVS的市场接受度。
Plug-in hybrid electric vehicles (PHEVs) provide much promise in reducing greenhouse gas emissions and, thus, are a focal point of research and development. Existing on-board charging capacity is effective but requires the use of several power conversion devices and power converters, which reduce reliability and cost efficiency. This paper presents a novel three-phase switched reluctance (SR) motor drive with integrated charging functions (including internal combustion engine and grid charging). The electrical energy flow within the drivetrain is controlled by a power electronic converter with less power switching devices and magnetic devices. It allows the desired energy conversion between the engine generator, the battery, and the SR motor under different operation modes. Battery-charging techniques are developed to operate under both motor-driving mode and standstill-charging mode. During the magnetization mode, the machine's phase windings are energized by the dc-link voltage. The power converter and the machine phase windings are controlled with a three-phase relay to enable the use of the ac-dc rectifier. The power converter can work as a buck-boost-type or a buck-type dc-dc converter for charging the battery. Simulation results in MATLAB/Simulink and experiments on a 3-kW SR motor validate the effectiveness of the proposed technologies, which may have significant economic implications and improve the PHEVs' market acceptance.
