FPGA aplicado no controle de um conversor boost com técnica de rastreamento de máxima potência para sistemas fotovoltaicos

Abstract

Faced with the global trend of energy transition to renewable sources, such as solar energy, this work seeks to contribute with improvements to the technology of photovoltaic systems that has been gaining popularity over the years. In this sense, using the MODELSIM simulator, this work aims to validate a modeling for tracking the maximum power of a photovoltaic system, contemplating the characteristics of the solar panel, the boost converter and the electrical load. The device used for the control was the FPGA and, through a logic written in the VHDL language, the signals that command the ADC were produced. It was also carried out, the tracking of the maximum potency, through the P&O method.
