摘要

本文对具有DC/DC反激变换器的光伏系统进行了稳定性分析。由于变换器的非光滑特性，传统的稳定性分析方法有一定的局限性，但用菲利波夫方法分析分段光滑系统是可能的。给出了由不同开关状态定义的每个曲面的函数。使用标称操作参数模拟转换器的行为。最后，我们通过相空间图分析了系统的稳定性，改变了负载电阻。

Stability analysis of a photovoltaic system with DC/DC flyback converter using Filippov's method

This paper presents stability analysis of a photovoltaic (PV) system with DC/DC flyback converter. Traditional methods of stability analysis have limitations due to the non-smooth nature of the converter, but it is possible to analyze a piecewise smooth system with the Filippov's method. Functions are presented for each of the surfaces defined by different switching states. Simulates the behavior of the converter using nominal operating parameters. Finally, we analyze the stability of the system, through a phase space diagram, varying the load resistance.
