SiC MOSFET Technology in Off-Highway Drive Trains; Unlocking advantages through system level design.

The growing requirement for higher-voltage power converters with increased power density for off-highway drive trains presents significant opportunities for SiC MOSFET technology; however, unlocking the full potential of this technology requires careful system-level design.

Williams Advanced Engineering has developed a 600kW DCDC converter for off-highway power conversion and portable EV battery charging, utilizing phase-interleaved 1k7V SiC MOSFET Modules.

This paper details the systems-level design decisions which were critical to overcome the significant challenges posed by ultra-fast switching, highly power-dense MOSFETs which need to operate in challenging environmental conditions, within stringent EMC regulations.
