摘要： A symmetric planar transformer having adjustable leakage inductance has a circuit board, two first bobbins mounted respectively on opposite side surfaces of the circuit board, two primary windings mounted respectively on the first bobbins, two secondary windings disposed respectively between the circuit board and the first bobbins, two second bobbins disposed respectively between adjacent first bobbins and primary windings, two pad sets disposed respectively between adjacent first bobbins and second bobbins, and a magnetic core assembly mounted through the circuit board, the first and second bobbins, the secondary and primary windings and the pad sets. Adjusting the numbers of the at least one pad of each pad set also adjusts distances between the primary and secondary windings to allow the secondary windings to have the same leakage. Thus, a balanced electric current is induced.
