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.

L'invention concerne un dispositif toroïdal inductif qui comprend un composant d'enroulement électrique (11) de forme généralement toroïdale et des composants magnétiques distincts (12) sous forme de sections toriques. Les composants magnétiques distincts (12) sont disposés sur le composant d'enroulement électrique de façon à être décalés de manière circonférentielle les uns par rapport aux autres et à entourer au moins partiellement le composant d'enroulement électrique (11). Les composants magnétiques (12) définissent des espacements de flux magnétiques dans des plans méridiens. L'invention concerne également un procédé de formation d'un composant magnétique selon lequel un câble magnétique est enroulé sur un composant d'enroulement électrique toroïdal sans faire passer de bobine dans une ouverture centrale du tore.
