Conversor CC-CC de Alto Ganho Boost-Quadrático-Duplo-Flyback

Abstract

O condicionamento entre fontes de tensão com baixa amplitude e cargas que exigem elevados níveis de tensão, especialmente para potências acima de 500 W, mostram-se como um desafio a ser resolvido. Nesse contexto, este artigo apresenta um novo conversor de elevado ganho e de elevado rendimento baseado em indutores acoplados e na estrutura boost-quadrática. O conversor proposto utiliza apenas um semicondutor controlado, indutores acoplados e capacitores na saída com baixa capacitância. A topologia permite o aproveitamento da energia oriunda das indutâncias de dispersão e possibilita que a corrente da entrada opere no modo de condução contínua. A validação dos conceitos foi realizada num protótipo de 1 kW com uma tensão de entrada entre 48 V e 96 Ve uma tensão de saída de 800 V. Os resultados experimentais foram coerentes com a teoria, o conversor permitiu elevado ganho de tensão e elevado rendimento para ampla faixa de potência, além do aproveitamento da energia das indutâncias de dispersão.
