Abstract
A gate driving circuit includes a driving stage configured to receive an input signal and generate a gate drive signal for a gate of a transistor switch. The gate driving circuit also includes an LC circuit having an inductor and a gate capacitance of the transistor switch. The LC circuit is configured so that a pulse in the gate drive signal generates a ringing in the LC circuit at a resonance frequency of the LC circuit to transfer energy into and out of the gate capacitance of the transistor switch. A switch could selectively couple the gate of the transistor switch to ground in order to discharge the gate capacitance. A control circuit could be used to provide the input signal, and the control circuit could be configured to regulate a duty cycle of the gate drive signal by adjusting an off-time between consecutive pulses in the input signal.
