摘　　要：针对电动汽车充电机网侧电流控制效果不理想的问题,建立了LCL结构PWM整流充电机数学模型,对其网侧电流谐波特性进行分析,在所搭建的仿真模型中,采用传统PI控制方法,利用仿真和实验验证了该方案能抑制充电机网侧电流谐波,改善网侧电能质量。In order to solve the problem of unsatisfactory effect on charger grid side current control of electric vehicle charger,in this paper,a mathematical model of PWM rectified electric charger with the structure of LCL has been established,of which the grid side current harmonic characteristics has been analyzed.Additionally,the established simulation models are controlled by traditional PI control method.The simulation and experimental results verify that this scheme is able to suppress the charger grid side current harmonic so that the grid side electric power quality would be improved.
