Hi

I saw your recent newsletter, SiC MOSFET modules were promoted for ebusses to run in auxiliary drives. What is the logic to shift to SiC for this application? Which benefits can I expect?

Many thanks

Hi Nick,

by using SiC Mosfets in eBus auxiliary drives you can provide silent operation without big penalty on losses. A drive based on silicon devices targeting the same noise level needs bigger output filter and bigger heatsink. Weight saving on these parts together with the increased efficiency of the drive will make the complete bus more efficient.

Best regards,
