Abstract
A gate driver circuit is provided that includes a turn-on path, a turn-off path, and a fast discharge path. The turn-on path is couplable between a gate of a solid-state switch and a voltage turn-on signal (VG) from a gate driver, where the turn-on path defines a turn-on time for the solid-state switch. The turn-off path is couplable between the gate and a voltage turn-off signal (VG) from the gate driver, where the turn-off path defines a turn-off time for the solid-state switch. The fast discharge path is selectively couplable in parallel with the turn-off path during a portion of a gate-to-source voltage (V) transition for the solid-state switch, where the turn-off path in parallel with the fast discharge path defines a turn-off delay for the solid-state switch and each of the turn-on time, the turn-off time, and the turn-off delay are independently configurable.
