Abstract
A transformer includes first and second primary windings serially electrically connected in a primary-side series combination. The transformer further includes a secondary winding disposed between the first primary winding and the second primary winding. The transformer further includes first and second shielding windings serially electrically connected in a shielding series combination. The first shielding winding is disposed between the first primary winding and the secondary winding, and the second shielding winding is disposed between the second primary winding and the secondary winding.
Claims16
A transformer, comprising:
- a first primary winding and a second primary winding serially electrically connected in a primary-side series combination, the primary-side series combination having a first primary-side terminal and a second primary-side terminal;
- a secondary winding having a first secondary-side terminal and a second secondary-side terminal and being disposed between the first primary winding and the second primary winding;
- a first shielding winding and a second shielding winding serially electrically connected in a shielding series combination at an intermediate shielding terminal, the shielding series combination having a first shielding terminal and a second shielding terminal;
- wherein:
- the first shielding winding is disposed between the first primary winding and the secondary winding;
- and
- the second shielding winding is disposed between the second primary winding and the secondary winding.
A method comprising:
- forming a first primary winding of a transformer;
- forming a first shielding winding of the transformer;
- forming a secondary winding of the transformer, the secondary winding having a first secondary-side terminal and a second secondary-side terminal, and the first shielding winding being disposed between the first primary winding and the secondary winding;
- forming a second shielding winding of the transformer;
- forming a second primary winding of the transformer, the secondary winding being disposed between the first primary winding and the second primary winding, and the second shielding winding being disposed between the second primary winding and the secondary winding;
- electrically connecting the first primary winding and the second primary winding in a primary-side series combination at an intermediate primary-side terminal, the primary-side series combination having a first primary-side terminal and a second primary-side terminal;
- and
- electrically connecting the first shielding winding and the second shielding winding in a shielding series combination at an intermediate shielding terminal, the shielding series combination having a first shielding terminal and a second shielding terminal.
