摘要
A DC-coupled two-stage gate driver circuit for driving a junction field effect transistor (JFET) is provided. The JFET can be a wide bandgap junction field effect transistor (JFET) such as a SiC JFET. The driver includes a first turn-on circuit, a second turn-on circuit and a pull-down circuit. The driver is configured to accept an input pulse-width modulation (PWM) control signal and generate an output driver signal for driving the gate of the JFET.
