Advanced DC/DC Full SiC Converter for On Board Heavy Traction Applications

The aim of this work has been the design and the manufacture of a DC/DC converter as a power supply for onboard rolling stock auxiliary systems. The converter is designed and made by means of Silicon Carbide device technology in order to achieve a compact and efficient design. Four modules connected in series as input stage can manage the nominal voltage of 3.6kV and the parallel connected output stages provide 45.5kW at 720Vdc.
