摘要:
针对电动汽车在启动、加速加载等工况下,蓄电池端电压因瞬间大电流放电而急剧下降,导致逆变器母线电压降低,电动汽车动力性能变差的问题,采用双向Z源逆变器代替传统的三相电压型逆变器驱动永磁同步电机,利用Z源逆变器独特的直通状态实现升压,并对其矢量控制算法进行了改进,搭建了矢量控制系统的仿真模型。结果表明逆变器母线电压得到了提升,输出电压谐波含量减少,有效改善了电动汽车的动力性能。
Abstract:
During the process of starting, accelerating, and loading of electric vehicles, the voltage at the battery terminal drops sharply due to the instantaneous high-current discharge, resulting in a decrease in the bus voltage of the inverter and a deterioration of the power performance of the electric vehicle. A bidirectional Z-source inverter was used. Instead of the traditional three-phase voltage-type inverter driving the permanent magnet synchronous motor, the Z-source inverter was used to achieve the boost state through a unique through-state, and its vector control algorithm was improved, and a vector control system simulation model was set up. The results show that the bus voltage of the inverter has been improved and the harmonic content of the output voltage has been reduced, which has effectively improved the power performance of the electric vehicle.
