| 摘 要： | 交流充电桩是家用电动汽车主要的能源供给设施，利用车载式充电机为动力电池充电。随着电动汽车充电站日益增多，其产生的谐波污染也越来越严重。搭建了单相车载式充电机的完整模型，详细分析了其谐波特点和充电机台数变化对谐波含量的影响。针对充电桩的谐波问题，将有源电力滤波技术应用到交流充电桩中。在所搭建的仿真模型中，针对单相车载式充电机的负载特性，采用传统PI控制与重复控制相结合的复合控制方法，新型交流充电桩有效地抑制了车载式充电器谐波，提高电网侧电能质量。

| Abstract: | AC charging spot, a major energy supply facility for electric vehicles, uses on-mounted charger to power the battery of household electric cars. The harmonic pollution of electric vehicle chargers is increasing rapidly as the scale of electric vehicle charging stations enlarge. This paper builds a model of single-phase vehicular charger. Besides, it analyzes the harmonic characteristics in detail. The influence on grid harmonic by the changes in the number of charging stations is analyzed. In view of the harmonic problem of charging spot, the active power filter technology is applied to the AC charging spot. In the simulation model, based on the load characteristics of single-phase vehicular charger, the traditional PI control and repetitive control are combined, which can improve the quality of the grid side power and reduce the influence of harmonics on electric energy.
