Current-compensated choke and method for producing a current-compensated choke

A method for producing a current-compensated choke, comprising:

• a) providing a ring core having an interior space containing a non-conductive body disposed therein, the non-conductive body comprising a first set of holes and a second set of holes, each hole extending from a first surface to a second surface of the non-conductive body, wherein each hole of the first set of holes opposes a corresponding hole of the second set of holes to form opposed pairs in a mirror symmetrical manner relative to a symmetry axis of the ring core, wherein the holes lying on a first side of the symmetry axis form a first group and the holes lying on a second side of the symmetry axis form a second group,
• b) guiding a first end of a first wire section through a first hole of the first group,
• c) guiding a second end of the first wire section in a loop enclosing the ring core through a second hole of the first group, wherein the first end of the first wire section is guided through the first hole in a direction opposite to the direction in which the second end of the first wire section is guided through the second hole,
• d) guiding a first end of a second wire section through a first hole of the second group,
• e) guiding a second end of the second wire section in a loop enclosing the ring core through a second hole of the second group, wherein the first end of the second wire section is guided through the first hole in a direction opposite the direction in which the second end of the second wire section is guided through the second hole,
• f) applying a tensile force to the first wire sections after c), d), or e) and applying a tensile force to the second wire section after d) or e).
