Abstract
A winding for a power transformer comprises a wire at least partially covered with a bonding material. The wire comprises a first winding formed into a first winding layer comprising a first plurality of turns positioned adjacently to each other, wherein the first plurality of turns are bonded together. The wire also comprises a second winding formed into a second winding layer from a first continuous wire portion extending from the first winding layer, the second winding layer comprising a second plurality of turns positioned adjacently together.

A winding for a power transformer, the winding comprising a wire at least partially covered with a bonding material;
- wherein the wire comprises:
- a first winding formed into a first winding layer comprising a first plurality of turns positioned adjacently to each other, wherein the first plurality of turns are bonded together;
- and
- a second winding formed into a second winding layer from a first continuous wire portion extending from the first winding layer, the second winding layer comprising a second plurality of turns positioned adjacently together.
A power transformer comprising:
- a primary winding formed from a continuous, single wire comprising a plurality of individual windings, each individual winding comprising a first plurality of turns bonded together via a bonding material at least partially covering the single wire;
- and
- a first secondary winding having a portion thereof positioned between a first individual winding of the plurality of individual windings and a second individual winding of the plurality of individual windings;
- wherein each individual winding of the plurality of individual windings is unbonded from each other individual winding.
A power transformer comprising:
- a multi-layer primary winding comprising multiple single layer, multi-turn windings stacked relative to each other;
- a plurality of secondary windings interleaved with the multi-turn windings of the multi-layer primary winding;
- wherein each multi-turn winding is formed in a respective portion of a continuous, single wire at least partially covered via a bonding material;
- and
- wherein each multi-turn winding is formed from a plurality of turns of the single wire positioned adjacently to each other in a planar layer.
