Abstract:
1. A transformer capable of suppressing a common mode current, comprising: a primary winding coupled to a primary side of the transformer; a secondary winding coupled to a secondary side of the transformer; a magnet core; and a shielding winding layer comprising a first shielding winding and a second shielding winding, wherein both the first shielding winding and the second shielding winding are coupled to the primary side or the secondary side, and the shielding winding layer is arranged between the primary winding and the secondary winding, and the first shielding winding comprises a first jump terminal and a first static terminal, and the second shielding winding comprises a second jump terminal and a second static terminal, and a voltage jump direction of the first jump terminal of the first shielding winding is constantly opposite to that of the second jump terminal of the second shielding winding, wherein the first static terminal and the second static terminal are coupled to a static terminal that is coupled with the primary winding or the secondary winding, and the first jump terminal and the second jump terminal are not connected together.
