Analysis of DC-DC converters for integrated photovoltaic solar-powered electric bus charging systems
| Resumo: | This dissertation aims to conduct a theoretical study and corresponding validation of the feasibility of using integrated photovoltaic systems for charging electric vehicles, specifically focusing on an electric bus as the model of study. The work begins with a theoretical analysis of photovoltaic systems, selecting the most suitable solar cells for application in an electric vehicle, considering performance, technical, and physical characteristics. This study includes the development of a mathematical model of the photovoltaic cells and their numerical simulation. Next, the design of an energy conversion system is addressed, using DC-DC converters. Different types of converters and their combinations are studied to maximize charging efficiency. The most appropriate topologies and control methods for the converters are discussed, aiming to optimize system performance. Finally, the proposed models are validated through simulations in Matlab/Simulink software, using lithium-ion batteries as the storage system. The dissertation seeks to demonstrate how the integration of photovoltaic solar energy can serve as a complementary and eco-friendly solution for charging electric buses, contributing to sustainability in transportation. |
