  • E cores are used with as many turns, which thereby have a higher leakage inductance compared to toroidal cores, thus approaching the desired behavior in terms of a moderately high leakage inductance.
  • conventional cores such as E-cores or toroidal cores, add an additional shunt body at a suitable position to give a higher stray inductance.
  • the shunt body can be inserted in the form of a magnetic core with specified properties, so that a higher leakage inductance can be set in a targeted manner as a function of the magnetic properties.

  • the leakage flux is determined exclusively by the core geometry, given given magnetic data and overall dimensions of the core, so that large numbers of current-compensated chokes can be produced with small range fluctuations.
  • the current-compensated chokes of the present invention are useful for low power applications ranging from 100 milliamps to several amps when efficient suppression of snubber signals is desired, while also enabling suppression of high power components efficiently based on the "oval" core shape.
  • the core shape according to the present invention ensures an automatable windability in connection with easily adjustable magnetic values, for example for the leakage flux, and the like.
  • a multiphase system is understood to mean that signals and in particular supply voltages and currents take place via at least three supply lines or phases in a phase-shifted manner.
  • the signal supply or the supply of the supply energy in the most symmetrical manner possible via the individual phases, but pronounced noise should be attenuated by the current-compensated throttle, as already explained above with respect to the two-phase current-compensated throttle.
  • Fig. 7a shows a schematic plan view of a magnetic core 710, although representing a closed core shape, which may be referred to in principle as a ring-core-like shape, but significantly deviates from a toroidal core, as shown in dashed lines as 711, so as to achieve a specially designed leakage inductance behavior , That is, the core 710 deviates from the toroidal shape 711 to desirably cause a higher leakage inductance when the core 710 is used as a core for a current-compensated reactor.
  • the desired deviation from the toroidal core shape 711 is achieved in the exemplary embodiment shown by providing arcuate regions 713A, 713B, 713C which give the core 710 a fundamentally toroidal shape, wherein an associated connection region is provided between each two adjacent arcuate regions which has a suitable shape to achieve the desired overall core shape.
  • three connecting portions 715A, 715B and 715C are provided corresponding to the three arcuate portions 713A713A ... 713C.

That is, in the illustrated embodiment, the core 710 is designed for a three-phase current system, such that the core 710 has threefold rotational symmetry with respect to a center M and a rotation axis perpendicular to the plane of the drawing Fig. 7a and passing through the center M has.
  • this also generates a magnetic symmetry in accordance with the geometric geometry, so that then a symmetrical electrical and magnetic behavior is obtained in accordance with the geometric symmetry.
  • the arcuate Areas 713A, ..., 713C each have a distance D1 from the center M, except for manufacturing tolerances
  • the connection areas 715A ... 715C have a distance D2 from the center M, which is different from the distance D1.

  • the core material of the respective regions also has a corresponding extent in a direction perpendicular to the plane of the drawing Fig. 7a has, as in the perspective view Fig. 2d is shown in a similar form for the core 210, the aforementioned definition shall apply to that edge line which results from a section through the core 710 corresponding to the median plane according to the perpendicular to the plane of the drawing Fig. 7a equivalent.
  • the in Fig. 7a represented level corresponds to this median plane.
  • the core 710 can also be designed for polyphase systems which require more than three phases and thus windings, so that a correspondingly larger number of arcuate regions 713A ... 713C and associated connection regions 715A ... 715C is to be provided.
  • a corresponding rotational symmetry for example, correspond to one Fourfold rotational symmetry, a five-fold rotational symmetry and the like. That in the illustrated embodiment, when rotated 120 ° about the axis of rotation through the center M, the same core configuration is again substantially obtained, while with quadruple rotational symmetry, rotation through 90 ° results in substantially the same core configuration.
  • This type of definition that is, the indication of distances of core regions to a common center point, a deviation of the core geometry from the toroidal shape 711, can also be applied to those previously described with reference to FIGS Fig. 2a to 2f apply the described current-compensated chokes, in which case the arcuate areas the Winding areas 212, 213 and the connection areas correspond to the regions 215 designated as the leakage inductance area.
  • the corresponding rotational symmetry would therefore be a 180 ° symmetry.
  • the distance of the arcuate regions 212, 213 from an imaginary center corresponds to half of the total geometric length 210 L, wherein of this geometric length according to the in Fig. 7a shown definition of the associated distances D1, the diameter or the maximum lateral extent of the core material is deducted.
  • the distance D2 corresponds to Fig. 7a half inside 2101 in Fig. 2a ,
  • connection regions 715A... 715C may have a geometric shape, as, for example, in principle also for the leakage inductance region 215 of the core 210 in FIG Fig. 2b or the core 210 in Fig. 2c is shown, so that on the one hand the leakage inductance can be suitably adjusted and on the other hand also suitable winding areas, such as in the arcuate areas 713A ... 713C, are generated.
  • connection regions 715A ... 715C may be used therefor.
  • appropriately designed rectilinear regions for example as shown schematically in the form of the region 715G, may be provided. The resulting stray inductance ratios can thereby be detected by simulation and / or by measurement technology.

  • the windings 720A... 720C can be applied in a manner suitable for automating, since in particular the connecting regions 715A... 715C are designed such that processing by means of a winding machine is possible when threading through the wires of the windings, as previously also with reference to FIG the current-compensated chokes 200 is explained.
  • the current-compensated choke 700 can also be designed for current systems with more than three phases, if correspondingly more arc-shaped regions and connecting regions are provided, as also explained above.
