Abstract

The inherent limitation of threshold voltage drift in silicon carbide metal-oxide-semiconductor field-effect transistors has restricted their broader applicability. This paper proposes a driving method that introduces an additional gate drive level, effectively reducing the threshold voltage drift in silicon carbide metal-oxide-semiconductor field-effect transistors while preserving the advantages of a negative gate turn-off voltage. The practical effectiveness of this method is validated through experiments.
