1. An inductive device, comprising:
- an electrical winding component of generally toroidal shape; and
a plurality of discrete magnetic components, each formed as a toric section bundle of magnetic wires or magnetic ribbons which is generally circular sector-shaped in plan view and at least partially embracing said electric winding component to complete a magnetic flux path in a meridional plane and further having end portions arranged to form at least one magnetic flux gap in the meridional plane.

Abstract
A toroidal inductive device has an electrical winding component (11) of generally toroidal shape and discrete magnetic components (12) shaped as toric sections. The discrete magnetic components (12) are arranged on the electrical winding component such that the discrete magnetic components (12) are offset circumferentially from each other and at least partially embrace the electrical winding component (11). The magnetic components (12) define magnetic flux gaps in meridional planes. A method for forming a magnetic component is also provided wherein magnetic wire is wound onto a toroidal electrical winding component without the need for passing a spool through a central opening of the toroid.

7. A magnetic component, comprising:
-
a member constructed of a bundle of magnetic wires or magnetic ribbons arranged as a generally toric-section having a circular sector-shape in plan view defined by an inner peripheral portion and an outer peripheral portion and opposite sides that diverge from respective spaced ends of the inner peripheral portion to respective spaced ends of the outer peripheral portion, and constructed such that the member can at least partially embrace an electrical winding of generally toroidal shape; and a magnetic flux gap in a meridional plane of said member of magnetic material. - View Dependent Claims (8, 9, 10, 11)
