Análise da modulação de um conversor multinível cascata com módulos integrados do tipo fonte dividida para sistemas fotovoltaicos

Abstract

The generation of electric energy, being generated, mainly through hydroelectric plants, grows every year, as the demand that technological evolution demands. With the worldwide concern for the environment, as well as the little incentive to maintain it, it is necessary new alternatives for the world’s energy generation, without the nature being extremely damaged in the process. One of these energies is the photovoltaic energy, which over the years, with the development of solar panels, and the great solar potential of Brazil, has the greatest strength in relation to researches currently. Research on the concept of multilevel cascaded has obtained new topologies, as well as great compatibility with the application in photovoltaic systems, with this, the application of solar panels on an industrial scale is very attractive due to its commercial and energetic attractiveness, with the use of converters, maximum power point tracking models, because they have the possibility of being applied directly to the grid, represent the new technological momentum in the field of world energy. The H bridge converters have been widely used in PV systems applications. However, a new topology called a split source converter can present better results and already shows potential for connection to the power grid. With this, this work proposes the modulation of a multilevel converter with cascade cells, with the split source inverter being used as the integrated converter.
