In this chapter, power losses and mass of optimally designed Si-vs. SiC-based isolated DC-DC converters are compared in quantitative terms. To that end, an adapted version of a computer-aided design tool, previously published by the authors, is used. The database of the existing tool was completed with new wide band gap semiconductor devices currently available from manufacturers. The results are presented for two switch-mode power supplies, each constituted of an isolated DC-DC converter, operating at very different power levels a kW auxiliary railway power supply and a multiple output . W power supply intended for a space application. The gains in terms of power losses and mass from one technology to the other can advantageously be evaluated thanks to the developed tool.

“…These specifications, used in the present paper, match with the nominal value of the catenary voltage of 1.5 kV dc . Moreover, the continuous failure‐free operation of the ARPS must be guaranteed within the following limits of the supply voltage (in dc traction systems) (Vinnikov and Bolgov, 2009): Equation 19 where V d,nom is the standardized nominal value of the catenary voltage.…”

Purpose -This paper presents a computer-aided design (CAD) tool for the design of isolated dc-dc converters. Design/methodology/approach -This tool, developed in Matlab environment, is based on multiobjective optimization (MO) using genetic algorithms. The Elitist Nondominated Sorting Genetic Algorithm is used to perform search and optimization whereas analytical models are used to model the power converters. The design problem requires minimizing the weight, losses and cost of the converter while ensuring the satisfaction of a number of constraints. The optimization variables are, as for them, the operating frequency, the current density, the maximum flux density, the transformer dimensions, the wire diameter, the core material, the conductor material, the converter topology (among Flyback, Forward, Push-Pull, half-bridge and full-bridge topologies), the number of semiconductor devices associated in parallel, the number of cells associated in series or parallel as well as the kinds of input and output connections (serial or parallel) of these cells. Finally, the design of an auxiliary railway power supply is presented and discussed. Findings -The results show that such tool to design dc-dc power converters presents several advantages. In particular, it proposes to the designer a set of solutions -instead of a single one -so that he can choose a posteriori which solution best fits the application under consideration. Moreover, interesting solutions not considered a priori can be found with this tool. Originality/value -To the best of the authors' knowledge, such a CAD tool including a MO procedure taking several topologies into account has not been suggested so far.
