Projeto e simulação de módulo conversor CC - CC trifásico série ressonante para processamento de microgeração fotovoltaica

Abstract

The demand for electric energy has significantly increased over the last few years. As a result, research centers, universities, companies, and government electric Power agencies have spared no effort in finding ways to overcome these new barriers to electricity production. However, concern for the environment and the future of energy sources has been a major obstacle in this journey. Therefore, solar power generation, also called photovoltaic generation, has become increasingly popular with the promise of addressing all these issues. In solar power plants connected to the electrical grid, a fundamental component is the photovoltaic inverter, which has the function of adapting the energy generated by the solar panels to the characteristics of the local grid energy. This study aims to analyze the topology of resonant series converters applied in a fullbridge three-phase converter in the scope of photovoltaic microgeneration, seeking to validate its operation at lower powers. The work consists of the mathematical development of the proposed model, followed by the design of the main and complementary circuits and their numerical analysis. These simulation results allow us to affirm that the project was well balanced, considering the small variation when compared to the theoretical data obtained.
