TL;DR: In this article, a gate drive circuit for an SiC-JFET in a bridge circuit that ensures a quick and stable switching has been proposed and demonstrated, where the gate voltage of an off-state transistor tends to rise up due to a steep drain-source voltage change caused by turning on of the transistor in the other side of the bridge circuit.
