Conexão diferencial, Processamento Parcial de Potência, Rastreamento do Ponto de Máxima PotênciaAbstract
Este artigo apresenta o conversor Buck–Boost diferencial simétrico, obtido da conexão diferencial entre dois conversores Buck-Boost. A topologia é caracterizada por apresentar baixa ondulação de tensão, processamento parcial de potência, capacidade de fornecer ganhos de tensão intermediários (1<M<10) e simplicidade de dimensionamento. O artigo apresenta a descrição do conversor proposto, suas principais equações e formas de onda em modo de condução contínua com modulação phase-shift, uma análise matemática que demonstra sua capacidade de realizar o processamento parcial de potência e uma análise comparativa com topologias similares publicadas na literatura. Além disso, resultados experimentais extraídos de um protótipo projetado para operar com frequência de comutação de 40 kHz, tensão de entrada de 105 V, tensão de saída de 400 V e potência nominal de 800 W são apresentados. Por ser destinado ao processamento de energia solar fotovoltaica, o conversor é validado em malha aberta e como rastreador do ponto de máxima potência, cuja eficiência CEC obtida é de 97,8%.
