Abstract
An active voltage-clamping gate driving circuit comprises a difference comparison circuit for receiving a reference voltage, a gate driving signal, and a preset voltage level, and outputting a voltage comparison signal; and a gate driving circuit for receiving an input signal and the voltage comparison signal, and outputting a gate driving signal. The voltage comparison signal controls the gate driving circuit. When a level difference between the gate control signal and the reference voltage is equal to the preset voltage level, the gate driving circuit is turned off, so that the level of the gate control signal is clamped to the preset voltage level, and the gate driving circuit does not output quiescent direct current under the clamped state.
