Abstract
An inductive coil comprises a plurality of wires wound about a winding axis. The plurality of wires comprises a first wire wound about the winding axis at a first distance from the winding axis and a second wire wound about the winding axis adjacently to the first wire and along a full length of the first wire and at a second distance from the winding axis. A first radial distance between the first distance and the winding axis is closer to the winding axis than a second radial distance between the second distance and the winding axis by a width of the first wire.

An inductive coil comprising:
- a plurality of wires wound about a winding axis and comprising:
- a first wire wound about the winding axis at a first distance from the winding axis;
- a second wire wound about the winding axis adjacently to the first wire and along a full length of the first wire and at a second distance from the winding axis;
- wherein a first radial distance between the first distance and the winding axis is closer to the winding axis than a second radial distance between the second distance and the winding axis by a width of the first wire.
An electrical transformer comprising:
- a core comprising a first lobe and a second lobe;
- a first primary winding comprising:
- a first wire encircling the first lobe at a first distance;
- and
- a plurality of additional wires, each additional wire positioned adjacently to a respective first primary winding neighboring wire positioned closer to the first lobe and encircling the first lobe at a distance greater than the respective first primary winding neighboring wire;
- a second primary winding comprising:
- a first wire encircling the second lobe at the first distance;
- and
- a plurality of additional wires, each additional wire positioned adjacently to a respective second primary winding neighboring wire positioned closer to the second lobe and encircling the second lobe at a distance greater than the respective second primary winding neighboring wire.
