Using Design by Optimization for Reducing the Weight of a SiC Switching Cell

This paper uses the design by optimization method todetermine the best combination of passives, EMC filter, heatsink,taking into account the components constraints, in order to reducethe weight of a SiC switching cell, implemented in a simple buckconverter. All elements and associated restrictions are describedusing analytical expressions, and the optimizer performs thereduction of the objective function (weight) respecting allconstraints. The models and the optimization strategy are described,and the optimization results are presented and discussed, incomparison with a conventional Si switching cell.
