Modelagem Do Conversor Boost Com Células A Capacitor Chaveado Por Meio De Um Conversor Equivalente De Ordem Reduzida

Abstract

Uma das formas de alcançar elevado ganho estático por meio do conversor boost clássico consiste na adição de células a capacitor chaveado a sua estrutura, originando os denominados conversores boost híbridos. Devido ao elevado número de elementos armazenadores de energia contidos nestes conversores, as funções de transferência que os representam são de ordem elevada e exigem grande esforço para serem obtidas. Neste artigo propõe-se uma metodologia que permite simplificar conversores boost híbridos genéricos (de ordem n) a um conversor dinamicamente equivalente, mas de segunda ordem. São apresentadas as equações que permitem determinar os parâmetros de equivalência, as funções de transferência orientadas ao controle e resultados experimentais, extraídos de um protótipo de 150 W, que validam a equivalência entre as respostas dinâmica do conversor boost híbrido e de seu modelo simplificado.
