Baratieri, Cássio LucianoDapper, Amerson André2022-02-012022-02-012021http://repositorio.uricer.edu.br/handle/35974/382The growth of research on energies used intelligently has provided several actions and practical applications. One way aims to parameterize a public lighting system. In this mode of analysis, the work proposes the development of a system of intelligent lighting fixtures for installation in public environments, as well as their automatic communication and activation, bringing safety and convenience. In short, the evolution of lighting in terms of installation, use and performance of LEDs (Light Emitting Diode) stood out, integrating systems and solutions. Therefore, literature reviews become fundamental for the advancement of new tools, such as an adjustable current source, especially directed to the desired luminance level in a specific area, as well as its easy and remote communication, bringing comfort and agility to the user. Respecting current Brazilian standards, as well as its technical institutions, a variable electronic product was stipulated, seeking to serve a demanding consumer market with a lot of access to information. Designed and simulated in PSIM, MATLAB and Autodesk EAGLE software and implemented on a bench, an open-loop control system applied to a Buck converter, with the possibility of application in closed-loop, from an proportional-integral (PI) controller. In view of the results, it appears that the control of the output current becomes viable, satisfying practical application and future commercial equipment.pt-BREngenharia ElétricaTrabalho de Conclusão de Curso
