摘　　要：提出了一种新型中性线谐波治理装置,通过3个单相变压器的特殊连接方式,仅使用一个单相全桥逆变电路即可完成补偿,同时避免承受电网基波电压,有效降低系统成本、开关损耗以及控制复杂程度;建立了其等效电压源模型,有效解决了电压型有源滤波器(APF)的控制跟踪问题;介绍了重复学习控制策略并给出其控制模型;研制了一套容量为10 kVA的实验装置,实验结果证明了算法的有效性。This paper introduces a new principle diagram of the active neutral line filter system in which the compensation was implemented by usage of only one single-phase inverter and connection of the three-phase four-wire system through three single-phase transformers all with turn ratio 1：1.The primary side used Yo type connection and the secondary side type,of which both ends were connected with the output of the inverter,instead of closing.Based on the new diagram and equal voltage source modelling,a method of repetitive learning control was achieved by FPGA and DSP.Simulative and experimental results provide the verification of these salient features.
