Claim 20:
21. The load control device of claim 12, wherein the first closed-loop gate drive circuit comprises:
a turn-on wave-shaping circuit configured to shape the first drive signal to generate a first target signal with a first shape during a first portion of a turn-on period and shape the first target signal with a second shape during a second portion of the turn-on period; and
a turn-off wave-shaping circuit configured to shape the first drive signal to generate the first target signal with a first shape during a first portion of a turn-off period and shape the first target signal with a second shape during a second portion of the turn-off period; and
wherein the first closed-loop gate drive circuit is configured to generate the first gate control signal in response to the first target signal and the drain-source current through the first semiconductor switch.
