Reator Eletrônico Auto-Oscilante com Variação Automática de Luminosidade e Detecção de Presença Empregando Microcontrolador

Abstract

Este artigo descreve um reator eletrônico com capacidade de variação automática de luminosidade e controle de presença aplicado a lâmpadas fluorescentes. Emprega-se comando auto-oscilante e microcontrolador de baixo custo. A proposta é de um reator que una a eficiência e simplicidade do comando auto-oscilante com a flexibilidade proporcionada por um microcontrolador, obtendo o máximo aproveitamento da luminosidade natural. O controle automático da potência na lâmpada é realizado através da variação da freqüência de comutação de um conversor half-bridge com comando auto-oscilante, utilizando o microcontrolador para o monitoramento e controle. O conversor alimenta uma lâmpada fluorescente de 40 W a partir de uma tensão de alimentação de 110 V, 60 Hz. O artigo inclui análise e descrição do sistema proposto, bem como resultados experimentais para a demonstração de seu desempenho.
