Abstract
A coil of electrically conductive material includes first and second sections, the first section including a first plurality of turns and the second section including a second plurality of turns. Both the first plurality of turns and the second plurality of turns are arranged around a winding axis of the coil. The first plurality of turns are smaller than the second plurality of turns such that when viewed along the winding axis of the coil, the first plurality of turns fit within the second plurality of turns. When viewed perpendicular to the winding axis of the coil, the first and second sections are adjacent.
Claims18
An electrical transformer comprising:
- a winding arrangement arranged around a transformer core, the winding arrangement including:
- a first coil and a second coil of electrically conductive material, each of the first coil and the second coil including a winding axis, each of the first coil and the second coil including:
- a first section including a first plurality of turns arranged around the winding axis;
- and
- a second section including a second plurality of turns arranged around the winding axis, the second plurality of turns being integral with the first plurality of turns;
- wherein
- an outer periphery of the first plurality of turns fits within an inner periphery of the second plurality of turns when viewed along the winding axis, and the first and second sections being adjacent when viewed perpendicular to the winding axis;
- the first coil and second coil are arranged coaxially such that the first section of the first coil is disposed within the second section of the second coil, and the first section of the second coil is disposed within the second section of the first coil;
- a spacing between adjacent turns of each of the first coil and the second coil is greater than a thickness of the electrically conductive material in a direction of the winding axis;
- and
- the first coil is coupled to an input of the electrical transformer and the second coil is coupled to an output of the electrical transformer.
