Patent ID: 8502571

Claim:
A gate driving circuit comprising: a control power; a transformer having a primary winding and a secondary winding; a first switching element; a second switching element; a rectifying element; and a capacitance element, wherein the first switching element is connected between the control power and one end of the primary winding, and the second switching element is connected to the other end of the primary winding, wherein both ends of the rectifying element are connected in parallel to both ends of the primary winding, wherein one end of the capacitance element is connected to either one of the one end and the other end of the primary winding, and wherein, when one of the first switching element and the second switching element is turned on, the capacitance element is charged by the control power, and when the other of the first switching element and the second switching element is turned on, the capacitance element is discharged.
