介绍了一种用于插电式混合动力汽车（PHEV）的开关磁阻电机（SRMs）的集成多电平变换器，该变换器采用模块化前端电路供电。通过改变前端电路中开关的ON-OFF状态，可以实现多种工作模式。在发电机驱动模式下，采用蓄电池组提高相电压，实现快速励磁和退磁。在电池驱动模式下，将变换器重新配置为四电平变换器，并将电容器作为附加充电电容器产生多级电压输出，增强了转矩能力。对所提出的驱动器的工作模式进行了说明，并对相电流和电压进行了详细分析。电池充电自然是由运动模式下的退磁电流和制动模式下的再生电流来实现的。此外，当车辆处于静止状态时，电池可以通过拟议的转换器由外部交流电源或发电机充电。基于srm的插电式混合动力汽车可以通过协调发电机和电池之间的功率流以不同的速度运行。在MATLAB/Simulink中的仿真和在三相12/8 SRM上的实验验证了所提出的转换器拓扑结构的有效性。
This paper presents an integrated multilevel converter of switched reluctance motors (SRMs) fed by a modular front-end circuit for plug-in hybrid electric vehicle (PHEV) applications. Several operating modes can be achieved by changing the ON–OFF states of the switches in the front-end circuit. In generator driving mode, the battery bank is employed to elevate the phase voltage for fast excitation and demagnetization. In battery driving mode, the converter is reconfigured as a four-level converter, and the capacitor is used as an additional charge capacitor to produce multilevel voltage outputs, which enhances the torque capability. The operating modes of the proposed drive are explained and the phase current and voltage are analyzed in details. The battery charging is naturally achieved by the demagnetization current in motoring mode and by the regenerative current in braking mode. Moreover, the battery can be charged by the external ac source or generator through the proposed converter when the vehicle is in standstill condition. The SRM-based PHEV can operate at different speeds by coordinating the power flow between the generator and battery. Simulation in MATLAB/Simulink and experiments on a three-phase 12/8 SRM confirm the effectiveness of the proposed converter topology.
