Frequency Model for EMI Study of Three-Phase Grid Connected Photovoltaic Inverter on Both DC and AC Sides
Résumé
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.
