Short Current Protection Circuit In EV Applications Based On GaN Transistors
In this presentation, an original derivative pulsed-current sensor in conjunction with the fast response 2-stage shutdown circuit is evaluated for various short-circuits. The protection circuit is developed and tested with the half-bridge converter evaluation board for 650 V / 80A GaN devices in various short circuit conditions.
