COIL FOR A SWITCHING DEVICE WITH A HIGH-FREQUENCY POWER
First Claim
1. A coil former for use in forming an electrical coil comprising several windings, the coil former having a generally conical shape, the coil former comprising:
- a first, relatively larger end;
a second, relatively smaller end;
a spiral track along the exterior of the coil former, the spiral track configured to accept an electrically conductive wire to thereby form said electrical coil comprising said several windings,wherein the spiral track across the coil former proximate to the first end has a first diameter and wherein adjacent loops of the spiral track proximate to the first end have a first spacing between said adjacent loops;
wherein the spiral track across the coil former proximate to the second end has a second diameter and wherein adjacent loops of the spiral track proximate to the second end have a second spacing between said adjacent loops of the spiral track proximate to the second end;
wherein the first diameter is larger than the second diameter; and
wherein the first spacing is smaller than the second spacing.

Abstract
A coil provides several windings. A first winding is a winding at one edge of the coil, which provides a given first winding diameter and a given first winding spacing relative to the next winding. At the other end of the coil, a last winding provides a given second winding diameter and a given second winding spacing relative to the adjacent winding. In this context, the first winding diameter is larger than the second winding diameter. The first winding spacing in this context is smaller than the second winding spacing.
