Definitions

  • the invention relates to a ferrite core for an inductance component, with at least two parallel legs arranged at the ends by a Yoke are connected.
  • the invention relates to a Ferrite core for a so-called resonance choke preferably for use in Switching power supplies.
  • the core can be inserted several air gaps are sheared.
  • z. B a segmented toroid used in which air gaps with Alternated ring core segments. Disadvantages are the high price, as it is still There are no finished multipart ring cores to buy and gluing together the parts is quite difficult. In addition, it is difficult to distance to the strand go, otherwise the winding window is getting smaller and the deposit of the Winding is no longer possible.
  • the winding length is the shortest and due to a large Surface / volume ratio the thermal properties at cheapest.
  • the object of the invention is a ferrite core for a Inductance component to create, with a high power density of the inductance can be reached and it is relatively easy and inexpensive to produce.
  • the Ferrite core should be particularly suitable for use in resonance chokes.
  • An essential feature of the invention is that the legs of the ferrite core of consist of several individual segments, each through an insulator, the is called a material with a permeability ⁇ ⁇ 1, are separated from each other.
  • the Isolators act as "air gaps" between the individual segments or Sections of thighs.
  • the segments and the Insulators glued together.
  • the legs have a round or oval cross-section.
  • a round or oval shape of the areas of the legs to be wound results minimal copper losses and is easy to wrap.
  • the legs can also have a polygonal cross-section.
  • the yoke preferably has a rectangular cross-section so that the ends the legs can be easily attached to a flat surface of the yoke.
  • the ferrite core according to another embodiment of the invention as E-shaped Core with three legs, which are connected by a yoke are connected.
  • the longitudinal axes of the legs all in one common level.
  • the longitudinal axes of the legs at least partially in lie on different levels, so that seen from above a triangular Arrangement of the legs results.
  • the thighs are then through a triangular Yoke connected.
  • an inductance component manufactured with the ferrite core according to the invention is preferably a resonance choke, wherein the legs with a preferably single-layer winding are provided.
  • the winding consists of HF stranded wire.
  • an insulator be such that a distance between the winding and the core or the respective air gaps.
  • a bobbin be that surrounds the core at least in the winding.
  • Another advantage of the invention is that the ratio of Winding window width to winding window height optimally to the respective Use case can be adjusted, for example, a single-layered To allow winding. This results in small Cu losses through Current displacement and a low-capacitance component.
  • the winding window height can be adjusted so that you have an ideal distance between strand and Air gap can adjust.
  • the preferably cylindrical segments of the legs are with a relative to produce simple tools and as such cheap.
  • the pressed "Ferrite tablets” require little or no post-processing before they can be glued together.
  • the segments are easy to glue and easy to wrap (layer wrap). You can even wrap directly on the core.
  • composite ferrite core is very variable, since one with two to three segment sizes, i. different diameters and heights, very can do many different chokes.
  • the design of the ferrite core according to the invention can relatively easily with a Heat sink are provided so as to the highest possible power density realize. Both the winding and the core itself provide enough "Attack surface" for a passive heat sink.
  • FIG. 1 shows a side view of the ferrite core according to the invention.
  • the Ferrite core consists essentially of two preferably cylindrical Legs 1, 2, whose ends are connected to each other by a yoke 3, 4 are.
  • the cylindrical legs 1, 2, also called slugs, are each made a plurality of preferably uniform segments 5, wherein these segments are separated from each other by insulating discs 6.
  • the Segments 5 and insulating discs 6 are glued together, as well as the Legs 1, 2 are glued to the respective yoke 3, 4.
  • the two legs 1, 2 carry a winding 7, as indicated in Figure 1 can be wound directly on the slugs 1, 2.
  • a single-layer winding 7 used.
  • the winding 7 is not directly on the leg 1, 2 applied. Instead, the legs 1, 2 are first with a Insulating material 8 wrapped on which insulating material 8 then the winding. 7 is applied.
