In this master thesis work, a 600/28V full-bridge DC/DC converter has been designed and investigated regarding its efficiency. As switching elements a SiC BJT and a conventional IGBT has been used. In addition, the Ebers-Moll parameters have been identified for a conventional BJT and the SiC BJT. Comparisons of the converter with the SiC BJT setup and the conventional IGBT setup have been made by simulations in MATLAB/Simulink. It was found that estimating the losses of the SiC BJT was not possible. Calculations of losses in the transformer and filter inductor of the DC/DC converter have also been made.
