Abstract: A planar transformer includes: a first primary winding layer; a second primary winding layer disposed adjacent to the first primary winding layer; a shielding layer disposed adjacent to the first primary winding layer; a first secondary winding layer disposed adjacent to the shielding layer; a second secondary winding layer disposed adjacent to the first secondary winding layer. The first primary winding layer and the second primary winding layer are located at one side of the shielding layer. The first secondary winding layer and the second secondary winding layer are located at another side of the shielding layer.
