The paper discusses the switching performance of the dual gate trench SiC JFET. In applications such as dc/dc converters, when fast switching is expected the standard totem-pole driver is not sufficient. The reason for this is that both the internal resistance and the parasitic capacitances of this device are significantly higher than for other designs. Instead, the gate driver with a dynamic current source is proposed in this paper to speed-up the switching process. Performed double-pulse measurements show improved dynamic performance of the tested DGTJFET with the new driver.
