Using design by optimization for reducing the weight of a SiC switching cell

摘要

This paper uses the design by optimization method to determine the best combination of passives, EMC filter, heatsink, taking into account the components constraints, in order to reduce the weight of a SiC switching cell, implemented in a simple buck converter. All elements and associated restrictions are described using analytical expressions, and the optimizer performs the reduction of the objective function (weight) respecting all constraints. The models and the optimization strategy are described, and the optimization results are presented and discussed, in comparison with a conventional Si switching cell.
