摘要
在低压电力系统的供电方式中,三相四线制以其特有的优越性在工业中得到广泛应用,因此解决谐波以及负载不平衡的问题也日益迫切。为此,基于三电平空间矢量脉宽调制(SVPWM)方法,针对三相四桥臂拓扑结构有源电力滤波器(APF)进行了研究,重点分析了谐波抑制及零序电流的补偿。使用仿真和实验进行了验证,结果表明该方法具有良好的补偿效果。
In low-voltage power supply, the three-phase four-wire system is widely used due to its specific advantages in industrial applications.Therefore,to solve the harmonic problem becomes urgent.This literature is based on the three-level space vector pulse width modulation (SVPWM) method, aiming to do research on active power filter (APF) of three-phase four-leg topology, and emphasize on analysis of harmonic suppression and compensation of zero-sequence current.The method is proved to be useful with simulations and experiments.
