Definitions
- the invention relates to a current-compensated radio interference suppression choke with a soft magnetic core for switching into the feed lines of a power electronics device.
- a current-compensated radio interference suppression choke is described for example in DE-A 35 26 047.
- the windings of this choke are switched so that the magnetic fluxes, which are induced due to the operating current, cancel each other out, while interference currents that flow in phase through both windings result in magnetization of the soft magnetic core.
- the resulting current-compensated radio interference suppression choke acts as a very small inductive resistor in relation to the operating currents, while interference currents, which originate, for example, from connected devices and close over ground, meet with a very high inductance.
- the core of the known current-compensated radio interference suppression choke is wound, for example, from an amorphous band.
- a very high permeability is achieved, which allows a high damping effect to be achieved with a small construction volume of the radio interference suppression choke.
- This is mainly due to the fact that the inductance of the choke depends not only on the number of turns and the core cross section, but essentially on the relative permeability of the soft magnetic material of the magnetic core.
- the object of the present invention is now to provide a radio interference suppression choke which has a good interference suppression effect even with such consumers, without requiring particularly large dimensions due to an increase in the number of turns and / or core cross section.
- the solution to this problem consists according to the invention in the choice of a core material for the soft magnetic core of a current-compensated choke with the features as listed in the characterizing part of patent claim 1. It is particularly advantageous if the core material consists of certain alloys specified in the subclaims and if the magnetic characteristic of this material is set accordingly by the measures mentioned there.
- the field is then applied in such a way that it acts as a transverse field, that is, the direction of magnetization of the applied field is transverse to the later direction of magnetization of the wound toroid.
- the nanocrystalline alloys described have a relatively high specific electrical Resistance R> 90 ⁇ cm. This limits the eddy current losses in the core caused by interference currents and can therefore also be used in relatively small sizes with regard to heating.
