Abstract: A transformer includes a magnetic core and four windings. The magnetic core includes a first flange, a second flange and a middle core part. The first terminal of the first winding, the third terminal of the second winding, the fifth terminal of the third winding and the seventh terminal of the fourth winding are disposed on the first flange. The second terminal of the first winding, the fourth terminal of the second winding, the sixth terminal of the third winding and the eighth terminal of the fourth winding are disposed on the second flange. The first winding and the second winding are twisted with each other to dispose around the middle core part. The third winding and the fourth winding are twisted with each other to dispose around the middle core part, or the third winding and the fourth winding are disposed around the middle core part in parallel.
