Resumo

In this paper, a data driven approach is used to obtain the static gain of dc-dc power converters in terms of the duty cycle and a set of linear coefficients. A known number of measurements, dependent on the dc-dc converter topology, are used to built-in a rational function obtained by linear coefficients. This solution shows how to use measurements to determine a function to represent the static gain of dc-dc power converters in the continuous-conduction mode (CCM). To validate the proposed approach, PSIM simulations, as well as experimental results are presented. The analysis was performed with a Interleaved Boost with Voltage Multiplier (IBVM) converter. Finally, the proposed approach is shown to be an alternative to the classical scanning methods or to the conventional solution of differential equations. Copyright (C) 2020 The Authors. (AU)
