Este artigo apresenta um conversor multifuncional para iluminação pública e injeção de energia na rede elétrica. O conversor proposto funciona no acionamento de uma luminária à LEDs durante a noite, utilizando energia proveniente da rede elétrica com elevado fator de potência e reduzida distorção harmônica. Durante o dia, o mesmo conversor opera injetando energia proveniente de um painel fotovoltaico na rede elétrica. A topologia utilizada é baseada na integração de dois conversores flyback, onde cada conversor opera em um semiciclo da rede elétrica, propiciando o fluxo bidirecional de energia. Um protótipo foi desenvolvido para comprovar a praticabilidade do sistema proposto. Resultados experimentais são apresentados.
