摘　　要：随着电动汽车的大力发展,充电桩应运而生。而充电桩产生的谐波对电网损害严重,首先分析了传统的滞环电流跟踪控制策略的缺点:环宽固定会使补偿能力不足和补偿效果不佳,本文针对此缺点提出了一种基于模糊理论的变环宽电流控制,目的是通过改变环宽的方法来实现对电流的动态跟踪控制。最后对两种谐波抑制策略进行仿真对比分析,结果表明基于模糊理论的变环宽滞环电流控制能够很好地进行动态补偿电流,补偿效果更佳。With the vigorous development of electric vehicles,charging piles came into being.However,the harmonics generated by the charging pile cause serious damage to the power grid.In this paper,the Active Power Filter(APF)is used to suppress harmonics.The traditional hysteresis current tracking control has the shortcomings such as insufficient APF compensation ability and unsatisfactory compensation effect.In this paper,the variable-loop wide-hysteretic current control based on fuzzy theory is proposed.By changing the ring width,the dynamic tracking control of the current is realized.Finally,the two harmonic suppression methods are simulated and analyzed.The results show that the variable-loop wide-hysteresis current control based on fuzzy theory can dynamically compensate the current well,and the compensation effect is better.
