Inversor Zeta Monofásico como Filtro Ativo de Potência para Sistemas Fotovoltaicos Conectados à Rede Elétrica

Abstract

Currently, with greater awareness about environmental impacts arising from electricity generation, there is a growing demand for forms of energy generation through renewable sources, such as solar and wind energy, to the detriment of known harmful impacts forms of energy, such as the burning of fossils fuels. In addition, the increase in the use of non-linear loads in recent decades has resulted in greater disturbances in the electrical network, such as harmonics, for example. Thus, this study aims to carry out an analysis and development of an integrated topology based on the DC-DC Zeta converter, which, in addition to operating as an interface converter when connected to a photovoltaic (PV) system, is responsible for injecting current into the electrical grid, can act as an parallel power active filter (FAPP) mitigating problems related to harmonics generated by non-linear loads, it is should be noted that this operation will be done through computer mathematical modeling and simulations.
