A gate driver of a power device includes a power supply and a resonant circuit. The power supply may have a positive potential and a negative potential. The resonant circuit may include an inductor and be configured to recirculate charge during turn-off by inducing a first field based on a positive charge from a gate caused by the positive potential, and in response to reversal of a voltage across the inductor, collapsing the first field to draw charge from the gate.
