Definitions

  • the invention relates to an inductive component for damping common-mode and push-pull interference in n-conductor systems with n ⁇ 2 conductors.
  • Push-pull interference only spreads along the connected lines, with the interference current in a two-conductor system flowing on one conductor to the interference sink and back on the other conductor to the interference source.
  • the two interference currents are therefore in push-pull mode, which is why this fault is referred to as push-pull fault or also as symmetrical fault.
  • Parasitic capacitances in the interference source and sink or the intended ground connections also result in an interference current in the earth circuit.
  • the interference current flows back on the conductors to the interference sink and via earth lines.
  • the interference currents on the lines are in common mode, which is why this interference is referred to as common mode or asymmetrical interference.
  • the object of the present invention is to provide an inductive component which combines the components for interference suppression of symmetrical and asymmetrical interference in one component for use in locking n (n ⁇ 2) lines, which component can be produced cost-effectively and has low self-losses.
  • the component consists of a body made of a permeable material, that the body has n holes and that the electrical conductors are arranged in the holes.
  • an inductive component 1 for suppressing a three-phase current with a 120 ° phase rotation is shown with three lines 2.
  • the inductive component 1 consists of a disk 3 with the radius R made of a permeable, preferably highly permeable, material. Holes 4 are arranged in the disk 3 on a radius r through which the electrical conductors 2 are guided. The holes 4 are arranged at an angle of 120 °, which results in zero as the sum of the currents of the introduced conductors 4. With this arrangement, the compensation of the magnetic fluxes generated by the operating current is achieved. This enables the use of highly permeable materials with very low saturation limits, which leads to very high inductances at high nominal currents.
  • the inductive component 1 acts like a current-compensated inductor with a high asymmetrically acting inductance depending on the radii R, r and the thickness of the disk 3.
  • the resulting symmetrically acting inductance is due to the shape of the disk 3, influenced by the type and location as well as the number of holes 4.
  • the saturation limit of the symmetrically acting inductor is increased, whereby the nominal current can also be increased further by this measure.
  • the location and type, as well as the number of air gaps is an instrument for adapting to a wide variety of requirements. By bridging an air gap, new air gaps can also be formed.
  • the inductive component according to the invention can be used in networks of alternating and direct current with a wide variety of harmonic and wave forms, current and voltage pulses for damping common and push-pull interference.
  • it is suitable for locking cables for a frequency range from a few kHz to a few GHz.
  • the operating currents range from a few mA to the kA range.
  • the inductors, which are used as interference elements in the interference suppression circuits have low self-losses.
  • Variants of the inductive component described in the above-mentioned exemplary embodiment are, for example, number of turns ⁇ 1 or different number of turns (based on individual conductors). Furthermore, by selecting different materials (permeability), arrangement and number of holes, design and number of air gaps and / or combination of different materials, adjustments can be made to the individual application. Furthermore, cascading (for example increasing the inductance by means of several, even different, panes in a row) and interconnecting differently shaped panes with a common conductor are also possible. When combined with that in the Multiple feedthrough capacitors described in DE 43 11 124 A1 provide filters for applications in the MHz range.
  • the body can also be designed in a different way (for example cylindrical, prismatic or the like).
  • the design depends on the requirements and, if necessary, on the number n of conductors.
  • the cross section of the body can be elliptical or oval for two conductors, rectangular for four conductors, pentagonal for five conductors and hexagonal for six conductors.
