摘要

Gate drivers for wide bandgap (e.g., 2eV) semiconductor junction field effect transistors (JFETs) capable of operating in high ambient temperature environments are described. The wide bandgap (WBG) semiconductor devices include silicon carbide (SiC) and gallium nitride (GaN) devices. The driver can be a non-inverting gate driver which has an input, an output, a first reference line for receiving a first supply voltage, a second reference line for receiving a second supply voltage, a ground terminal, and six Junction Field-Effect Transistors (JFETs) wherein the first JFET and the second JFET form a first inverting buffer, the third JFET and the fourth JFET form a second inverting buffer, and the fifth JFET and the sixth JFET form a totem pole which can be used to drive a high temperature power SiC JFET. An inverting gate driver is also described.
