Modelagem e Controle de um Inversor Diferencial Buck-Boost com Técnica de Linearização de Ganho Estático para Redução de Distorção Harmônica

Abstract

Este trabalho contribui no estudo do inversor diferencial Buck-Boost com técnica de linearização de ganho estático. O modelo dinâmico é desenvolvido e validado via comparação da reposta ao degrau e da resposta em frequência do modelo comutado e do modelo de pequenos sinais. O uso da linearização e da modelagem permitem a redução da distorção harmônica da tensão de saída do inversor, projeto do controlador através de técnicas clássicas e aplicação de um controlador proporcional ressonante para seguimento de referência. As especificações utilizadas são: potência de 250 W, tensão de entrada de 100 V e tensão eficaz de saída de 110 V. Por fim, são apresentados os resultados de simulação com o intuito de validar o estudo e verificar a qualidade da tensão de saída. Ao comparar a distorção harmônica da tensão de saída com e sem técnica de linearização, tem-se uma redução de 5,96% para 0,274%.
