Abstract
In an embodiment a choke includes a core assembly and a winding block having a predetermined number of turns for each conductor of a multi-conductor system, wherein the core assembly comprises at least one stacking unit comprising a closed ring and a separation unit, wherein the separation unit comprises a separation segment for each conductor, the separation segments being arranged on a first surface of the ring in a pre-determined spaced-apart relationship along a circumferential line of the ring such that a gap is present between each of the adjacent separation segments, wherein each separation segment comprises a ferromagnetic material and/or the closed ring is formed as a closed magnetic toroidal core, wherein the core assembly has an inner opening enclosed by the ring and at least partially by the separation unit, and wherein the winding blocks are arranged in correspondence with the separation segments so that windings of respective winding blocks extend through the inner opening of the core assembly and enclose the ring and the corresponding separation segment.
