1. An apparatus, comprising:
- a first conductor within a laminated composite assembly, the first conductor (1) having a winding portion within a winding region of the laminated composite assembly and a terminal portion within a terminal region of the laminated composite assembly and (2) defining a first layer;
a second conductor within the laminated composite assembly, the second conductor (1) having a winding portion within the winding region and a terminal portion within the terminal region and (2) defining a second layer substantially geometrically parallel to the first layer, the winding region including at least one electrical interconnect electrically coupling the winding portion of the first conductor with the winding portion of the second conductor; and
a third conductor within the laminated composite assembly, the third conductor (1) having a winding portion within the winding region and a terminal portion within the terminal region and (2) defining a third layer substantially geometrically parallel to the first layer and the second layer, the winding region not including an electrical interconnect between the winding portion of the third conductor and the winding portion of the first conductor, the winding region not including an electrical interconnect between the winding portion of the third conductor and the winding portion of the second conductor, the terminal region including at least one electrical interconnect electrically coupling the terminal portion of the first conductor with the terminal portion of the second conductor and the terminal portion of the third conductor.

Abstract
In some embodiments, a system includes three conductors, each conductor being on a separate layer such that the layers are parallel to one another and stacked. Each conductor has a winding portion and a terminal portion. The conductors are configured such that at least one electrical interconnect electrically couples two adjacent conductors within the winding portion but the third conductor is electrically isolated from the other two conductors within the winding portion. Within the terminal portion all three conductors are electrically coupled.
