Claim 13:
14. A coil arrangement with reduced losses and a stabilized coupling factor, comprising
a coil core defining an axis;
a first winding having turns that are wound around the axis of the coil core, the turns of the first winding being grouped into at least a first section and a second section, the first section being separated from the second section by a region that lacks the turns of the first winding;
a second winding having turns that are wound around the axis of the coil core, the turns of the second winding being grouped into at least a third section and a fourth section, the third section being separated from the fourth section by a region that lacks the turns of the second winding; and
a switch positioned between the first section and the second section and configured to either (a) bypass the second winding by connecting the first section to the second section, or (b) arrange the first winding and the second winding in series by connecting the first section to the third section,
wherein the fourth section is connected to the second section,
wherein the first section and the second section are arranged at opposing ends of the coil core, and the third section and the fourth section are situated between the first section and the second section.
