A power transformer combined with balance windings is used for driving a CCFL. The power transformer makes use of a ferrite core structure to achieve a closed magnetic circuit, and is combined with balance windings. When used in application circuits, the power transformer combined with balance windings can provide stable induction voltages and balance load currents to CCFLs to enhance the luminous efficiency and uniformity of the CCFLs, thereby improving the drawbacks of a irregular current flowing through the CCFLs and too high a manufacturing cost of conventional CCFL application circuits.
