Abstract
A converter device comprising a converter and a coil arrangement that contains a number of coils. The coil arrangement has a plurality of interconnected coils. Torroidal cores of a soft magnetic nanocrystalline material are associated with each of said coils. A coupling toroidal core (11) is provided with a core opening (12) through which at least two windings (8, 9) of different coils can be guided and mounted. At least the winding of one coil is guided and mounted through a core opening of an individual toroidal core (13, 14). An an open/closed-loop control device is provided with a current controller that acts on the coils such that direct current components are compensated by currents flowing through the windings of the coils.

A converter device comprising a converter and a coil arrangement (1, 2, 3, 4, 31) that contains a number of coils, wherein
- the coil arrangement (1, 2, 3, 4, 31) has a plurality of interconnected coils, and wherein toroidal cores consisting of a soft magnetic material are associated with each of said coils,
- a coupling toroidal core (11, 11′, 16, 16′) is provided with a core opening (12, 12′, 16, 16′) through which at least two windings (8, 9, 381, 382, 38n-1, 38n) of different coils can be guided and mounted,
- at least the winding (8, 9) of one coil is guided and mounted through a core opening of an individual toroidal core (13, 14), and
- an open/closed-loop control device is provided with a current controller that acts on the coils such that direct current components are compensated by currents (i1, i2 . . . in) flowing through the windings (8, 9) of the coils.
A coil arrangement for voltage regulator circuits (5), comprising a coil that contains a toroidal core (11) consisting of a soft magnetic nanocrystalline material and a winding (8, 9) which is guided and arranged through a core opening (12) of the toroidal core (11), wherein a coupling toroidal core (11) is provided with a core opening (12) through which at least two windings (8, 9) of different coils can be guided and mounted, at least one winding (8, 9) is guided and mounted through a core opening of an individual toroidal core (13, 14), and an open/closed-loop control device is provided, by means of which electric currents (i1, i2) flowing through the windings (8, 9) are acted on such that direct current components of the currents (i1, i2) are compensated.
A coil arrangement comprising a coil that contains a toroidal core consisting of a soft magnetic nanocrystalline material and a winding which is guided and arranged through a core opening of the toroidal core, wherein a coupling toroidal core (11) is provided with a core opening (12) through which at least two windings (8, 9) are guided, no individual toroidal core is associated with a first winding (8), an individual toroidal core (14) is associated with a second winding (9), and wherein the second winding (9) can be switched in a currentless or current-carrying manner, so that an inductance (L1) of the first winding (8) can be modified between a first inductance in which the second winding (9) is open, and a second inductance in which the second winding (9) is current-carrying.
