Visita aos Conceitos de Modelo Chaveado, Médio e de Pequenos Sinais de um Conversor CC-CC

This paper, as part of the activities developed in scope a R&D+I, review is carried out fundamentals switched, average and small-signal models DC-DC converters, order to provide clear objective concepts. Starting from PWM modulator, concepts switching function its Fourier series decomposition are presented obtain switched model converter. Based on averaging operator, averaged stationary states defined, which starting point for linearization Writing state output vectors form multivariable functions, Taylor used linearized The results numerical solutions, their analysis conclusions reveal characteristics applications models.
