摘要
提出了一种新型中性线谐波治理装置,通过三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要求,同时避免承受电网基波电压,有效降低开关损耗以及控制复杂程度;介绍了重复学习控制策略并给出其控制模型;最后使用FPGA和DSP给出了该控制的数字算法实现并研制了一套容量为10kVA的装置进行实验。
This paper introduces a new principle diagram of the active neutral line filter system that only uses one singlephase inverter to realize compensation by connecting three single-phase transformers all with turn ratio 1：1. The primary side is Y0 type connection and the secondary side triangle type, of which both ends are connected with the output of the inverter, instead of closing. Based on the new diagram, a method of repetitive learning control is achieved by FPGA and DSP. The achievement has the features of robustness, zero steady-state error, fast dynamic response.
