为了降低现有大电流充电机在充电过程中注入电网电流的谐波含量，使之符合国家电网公司规定的电流标准，对现有充电机充电电流的谐波含量进行了理论分析，利用十二脉整流和增加并联APF的方式来抑制充电过程中注入电网的电流谐波含量过高的问题。在Matlab／Simulink环境下搭建不同充电机仿真模型进行仿真分析，证明了上述两种方法对现有充电机的谐波抑制有非常好的效果。

In order to reduce the current harmonic content of the existing electric bus heavy-cur-rent charger in the process of charging into the grid and meet the requirements of state grid corpo-ration current standards ,we made theoretical analysis and proposed to deal with problem of har-monic content overtop by using 12-pulse rectifier charger and adding parallel APF .Then we set up different type simulation models of electric bus charger for the simulation analysis in the envi-ronment of Matlab/Simulink ,and proved that the above two methods in harmonic suppression of existing electric bus charger have very good effect .
