Microinversor Cuk de estágio único para aplicação em energias renováveis

Abstract

The present work has a theoretical and experimental approach about the application of electronic converters in power processing provided by renewable sources of electrical energy. Therefore, it brings an overview of the current state of the photovoltaic power generation, as well as the most usual methods for grid power injection. Followed by a presentation of the most used power convertes, specifying the Cuk microinverter, which is the main subject of this work. A quantitative and qualitative analysis of the proposed microinverter topology was made, followed by its validation through simulation. The designed prototype was implemented experimentally with resistive load, which represents the grid, to verify the converter operation and the research made.
