摘　　要：充电装置的高效性和稳定性要求随着电力车辆的普及而不断提高。研究了一种基于三电平的交流充电装置,除了具有参与网侧削峰填谷的功能,还能对用户侧产生的电能质量问题进行就地补偿。对于LCL型滤波器,通过数学建模的方法分析了其存在谐振峰值的理论依据,给出滤波电容串、并联电阻的阻尼控制框图,仿真和实验验证了有源阻尼控制方法对电流谐振和电压谐振的抑制效果显著。The higher efficiency and stability of the charging device is increasing with the popularization of electric vehicles（EV）.Therefore, a three-level converter based alternating current charging device is proposed, in addition to the participation in the network side of the peak clipping function, hut also to the user side of the power quality problems generated in situ compensation.For the LCL type filter,through the method of mathematical modeling analysis of the theoretical basis of its existence resonance peak, given filter capacitor series and parallel resistor damping control diagram, simulation and experimental results show the active damping control method has a significant effect on the current resonance and voltage resonance.
