Switching of a Bus Voltage of 1400 V at 10 MHz Using Vertical GaN Fin-JFETs
The fast-switching performance results of a 1200 V rated normally-off vertical GaN Fin-JFET are presented in this paper. A compact SPICE model which predicts its DC and dynamic behavior is presented and the anticipated switching performance is verified by measurement using a custom double pulse clamped inductive switching (CIS) circuit. As far as we know, this is the first report of a device switching 1400 V allowing for 10 MHz operation.
