MOSFETs under short circuit conditions for aeronautical applications

The short circuit performance of silicon carbide MOSFETs has been evaluated in a 270 V system designed to mimic the characteristics of a commercial airliner power system. The devices demonstrated the ability to withstand being short–circuited for a period of 8 µs before suffering a catastrophic failure when that coincided with the turn–off transient for a 9 µs pulse. At the point of turn off the j...
