Informações sobre o curso: Esse curso ensina como projetar o sistema de controle de uma fonte chaveada. O modelo de circuito equivalente encontrado nos cursos anteriores é extendido para modelo de pequenos sinais variações ca. Esse modelos são solucionados, para encontrarmos as funções de transferência dos conversores e sua malha de controle. Finalmente, a malha de feedback é modelada, analizada, e projetada para atender requisitos como regulação da saída, banda de passagem e resposta transiente, e rejeição de perturbações. Ao completar o curso, você será capaz de projetar e analisar sistemas de controle de fontes chaveadas. Esse curso tem como pré-requesito os cursos de Introdução a Eletrônica de Potência e Circuitos de Conversores.

good course!!!
I have got another great experience through this coursere. Thanks to Professor and the community on the forum, I was able to understand much better the converter control techniques. I am looking forward to finish all the Power Electronic Specialisation courses. Thank you!
This is the important part of converters to learn.It shows how much complex the systems will be and shows how can we minimize complexity by taking approximations.
