摘　　要：电动汽车充电机是非线性很强的负载,充电时会给电网带来较大的谐波污染,分析充电机谐波并进行谐波抑制对今后大规模充电站的建设具有重要意义。利用MATLAB/Simulink软件建立6脉波不控整流充电机模型,分析单台和多台充电机接入电网产生的谐波。最后,使用无源滤波器来抑制谐波,达到了预期效果,为今后大规模充电站建设提供一种理论参考。Electric vehicles charger is a kind of strong nonlinear load, which brings harmonic pollution to grid when it works. To analyze and suppress its harmonic is of great significance for large-scale construction of charger in the future. Utilizing MATLAB/Simulink software, simulation model for 6-plus uncontrolled rectifier was built, and harmonic of single or multiple chargers was analyzed in this paper. Finally, passive filter was used in the suppression of harmonic, and the expected effect was achieved, which provided a theoretical reference for large-scale construction of charging stations in the future.
