Abstract
A method, system, and apparatus for driving a Silicon Carbide (SiC) Junction Field Effect Transistor (JFET) are provided. A boosting capacitor is used in combination with two drivers to efficiently provide a boosting current to the SiC JFET and then a holding current to the SiC JFET. The boosting capacitor, upon discharge, creates the boosting current and once discharged the holding current is provided by one of the first and second drivers.
