Suitability of silicon carbide diodes in buck converters with high input voltages and high voltage conversion ratios

This paper presents a suitability analysis of silicon carbide diodes in buck converters with high input voltage and high voltage conversion ratio functional requirements. It provides a comparison of a conventional buck converter with silicon carbide diodes and ultrafast silicon diodes, illustrating the benefits of silicon carbide diode zero reverse-recovery losses. Experimental results are provided for a 768 W prototype.
