Resumo: | Photovoltaic power systems have been widely spread in the last years, especially for their versatility, the price reductions provided by production scale, the advances in the solar panels conversion efficiency and the incentives for use of renewable sources of energy. However, the power conversion stage necessary to inject the generated power into the grid involves the use of electronic devices whose switching process may generate voltage and current waveforms with a high frequency spectral content that interacts with other system components, frequently producing unexpected and undesirable effects, related with electromagnetic interferences, mainly the common-mode current flow. This work proposes to investigate the different particularities of the system which propitiate the occurrence of these phenomena and how to mitigate their effects, focusing grid-connected PV systems usually installed in commercial buildings, schools and residential installations. |
