摘要
电动汽车充电过程中会产生谐波,常采用并联有源电力滤波器(Active Power Filter,APF)的方式来补偿谐波。但是并联APF在补偿谐波时会产生谐波放大效应。文中通过采用等效电路分析的方法,提出一种量化谐波放大程度方法,根据此方法来改进谐波补偿电路的拓扑结构,以消除谐波放大效应,最后在MATLAB仿真软件上验证此方法的正确性。文章的研究有利于提高电动汽车充电站中并联APF的设计和利用。
Electric vehicle charging process will produce harmonics, we often adopt shunt active power filter （APF） to compensate harmonics. However, shunt APF will generate harmonic amplification effect during compensating har- monics. This paper proposes a method to quantify the degree of harmonic amplification by using equivalent circuit a- nalysis, as a result, the topological structure of harmonic compensation circuit is improved according to this method, and the harmonic amplification effect is also eliminated. Finally, the correctness of the method is verified by MATLAB simulation software. This study will help to improve the design and utilization of shunt APF in electric vehicle charging stations.
