摘要

本文旨在提出一种新的选型方法,以减少使用并网单相微型逆变器的光伏系统中 LCL 滤波器的占地面积并优化其性能。具体来说,分析是在单相全桥逆变器上进行的,并假设以下两个条件:(1)交流电网与 LCL 滤波器连接点的单位功率因数;(2)基于单极正弦脉宽调制 (SPWM) 的控制电路。其中,分析了 LCL 滤波器输入电流的纹波和谐波以及注入电网的电流。Simulink 仿真和实验测试的结果证实,与现有文献相比,通过优化每个无源元件,可以大大减少滤波器的体积,同时保证出色的滤波性能。具体来说,电感值减少了近 40%,电容值减少了近 100%。这种新的设计方法主要应用于与电网连接的单相微型逆变器,以及电力电子学和优化方面的研究。

A New LCL Filter Design Method for Single-Phase Photovoltaic Systems Connected to the Grid via Micro-Inverters
This paper aims to propose a new sizing approach to reduce the footprint and optimize the performance of an LCL filter implemented in photovoltaic systems using grid-connected single-phase microinverters. In particular, the analysis is carried out on a single-phase full-bridge inverter, assuming the following two conditions: (1) a unit power factor at the connection point between the AC grid and the LCL filter; (2) a control circuit based on unipolar sinusoidal pulse width modulation (SPWM). In particular, the ripple and harmonics of the LCL filter input current and the current injected into the grid are analyzed. The results of the Simulink simulation and the experimental tests carried out confirm that it is possible to considerably reduce filter volume by optimizing each passive component compared with what is already available in the literature while guaranteeing excellent filtering performance. Specifically, the inductance values were reduced by almost 40% and the capacitor value by almost 100%. The main applications of this new design methodology are for use in single-phase microinverters connected to the grid and for research purposes in power electronics and optimization.
