Abstract
Versions of the present invention have many advantages, including operation under high temperatures, or high frequencies while providing the required current for switching a SiC VJFET, providing electrical isolation and minimizing dv/dt noise. One embodiment is a silicon carbide gate driver comprising a first group of silicon on insulator devices and passive components and a second group of silicon carbide devices. The first group may have equivalent temperatures of operation and equivalent frequencies of operation as the second group.
