Desenvolvimento de um reator eletrônico para lâmpadas fluorescentes tubulares com variação automática da intensidade luminosa

Abstract

This work aims to develop a methodology for the design and development of an electronic ballast based on a half-bridge inverter with asymmetric resonant with the possibility of automatic adjustment of light intensity. To better understand the operation of electronic ballasts will be presented with a study of the behavior of fluorescent lamps and power characteristics, after which the study will be presented topologies frequency inverters and resonant filters. From the characteristics of the inverter and filters can determine the most suitable to be used in the project ultimately will be a proposal to integrate the circuit electronic ballast to control the luminous intensity of light according to ambient light, minimizing so unnecessary consumption of the lamp and maintaining the environment with a luminosity constant, and sogenerate energy savings.
