Micro inversor monofásico não conectado à rede para aplicação em fontes renováveis de energia e corrente a alternativa

Abstract

The renewable energy market is quickly increasing nowadays, as these alternatives have proven to be a way of meeting human needs while maintaining a respectful relationship with nature and everything it provides to people. The purpose of this work is to develop converters that are capable of adapting the energy generated by wind generators, making it possible to use it to supply power to conventional electrical devices. Initially, a rectifier is going to be developed to convert the AC generated energy to DC. Then this energy is going to be converted to the needed voltage level using a DC-DC converter. Finally, an inverter circuit is going to be developed to transform this energy back to AC, but with single-phase grid compatible voltage and frequency. An MPPT control is going to be implemented through the converter circuit to provide the maximum power available from the source. The following work presents a brief introduction to the renewable energies currently used, and then introduces the reader to the subjects to be addressed in it. After the explanation of the concepts and topologies that are going to be used, the project proposal can be observed, contemplating a detailed simulation of each stage of the circuit to be developed, in addition to a final simulation of the results of the circuit as a whole. Next, is the methodology for developing the prototype and analyzing the results obtained in practice. [resumo fornecido pelo autor]
