This invention discloses a driving circuit for a power device, including a negative voltage capacitor circuit, a pre-charge module, a power output stage, and a charging pull-down module. The negative voltage capacitor circuit provides a negative voltage for turning off the gate of the power device when the received unipolar output drive signal is a turn-off signal. The pre-charge module pre-charges the negative voltage capacitor circuit. The power output stage outputs a unipolar output drive signal to the negative voltage capacitor circuit according to the input signal. The charging pull-down module pulls the gate voltage of the power device to ground during pre-charging and replenishes the charge of the output capacitor when the power output stage outputs the unipolar output drive signal. This invention, while ensuring a simple, reliable, low-pin-count, and low-power structure, can effectively generate a negative voltage turn-off signal, ensuring the power device topology's anti-interference capability against voltage spikes under high-speed switching and improving the reliability of driving the power device topology.
