Performance of a 25kW 700V Galvanically Isolated Bidirectional DC-DC Converter Using 1.2kV Silicon Carbide MOSFETs and Schottky Diodes

Article Preview

Abstract:

This paper presents the development and experimental evaluation of a 25kW, 700V galvanically isolated bidirectional converter based on silicon carbide (SiC) MOSFETs and Schottky diodes. Compared with a similarly rated silicon (Si) IGBT version, the SiC converter exhibits a 3% improvement in peak efficiency, 2.6 times reduction in total losses, and three times improvement in power density.
