Toroidal Inductive Devices And Methods Of Making The Same

摘要

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.
