Claim 4:
5. The gate driving device according to claim 1, further comprising:
a resistor and a regulator device coupled in series and coupled between the positive power rail and the negative power rail, wherein a node between the resistor and the regulator device is coupled to the low-voltage terminal;
a transformer having a primary side coupled to a first capacitor, wherein a secondary side of the transformer has a first end and a second end, the first end of the secondary side is coupled to the UVLO circuit, and the second end of the secondary side is coupled to the low-voltage terminal;
a pulsating alternating-current (AC) voltage source coupled to the primary side through the first capacitor;
a diode having an anode coupled to the first end of the secondary side and a cathode coupled to the positive power rail; and
a second capacitor coupled between the positive power rail and the negative power rail;
wherein the AC voltage source is configured to provide the driving voltage, the positive power voltage, and the negative power voltage through the first capacitor, the diode, the resistor, and the regulator device.
