First order design by optimization method: Application to an interleaved buck converter and validation

This paper presents a design methodology of power converter and its components using deterministic algorithms associated with differentiable models. This “first order” design by optimization method is illustrated in the case of an Interleaved Buck Converter used in a stratospheric airship. The requirements and the models are briefly presented as well as the optimization results in the imaginary space of continuous variables. The method to come back in the power electronics world with its discrete variables is presented and validated with a prototype of Interleaved Buck Converter.
