摘要

本文采用传统的升压逆变器拓扑结构,建立了并网三相光伏逆变器的频率域电磁兼容模型。目的是估计直流和交流两侧的EMC噪声,以便设计例如EMI滤波器,或进行任何灵敏度分析或优化过程。该模型在实验样机上进行了开发和验证。通过考虑噪声的阻抗路径,重点讨论了每个变换器对直流和交流侧产生的噪声的贡献。

Frequency Model for EMI Study of Three-Phase Grid Connected Photovoltaic Inverter on Both DC and AC Sides
This paper presents an EMC model in the frequency domain for grid connected three-phase photovoltaic inverters using the conventional Boost-Inverter topology. The aim is to estimate the EMC noises on both DC and AC sides, in order to design for instance EMI filters, or for any sensitivity analysis or optimization process. The model is developed and validated on an experimental prototype setup. The results are discussed, focusing on the contribution of each converter to the noise produced, both on the DC and AC sides by considering the impedance path of noises.
