Stromkompensierte Ringkerndrossel mit erhöhter Streuinduktivität Current-compensated toroidal core choke with increased leakage inductance

In der Entstörtechnik sind allgemein stromkompensierte Ringkern drosseln mit magnetisch leitendem Kern, insbesondere aus einem geeigneten Ferrit bekannt. Diese Art von Drosseln beseitigt im Normalfall nur die sogen, asymmetrischen Störungen. Nun treten in störenden Geräten darüber hinaus aber auch noch symmetrische Störungen auf, die ggf. durch zusätzliche Maßnahmen, z.B. Stabkerndrosseln, beseitigt werden müssen. Der Aufwand ist somit hc und es war eine Lösung zu finden, die sowohl die asymmetrischen als auch die symmetrischen Störungen mit einem Bauteil zu besei tigen.In interference suppression technology, current-compensated toroidal core chokes with a magnetically conductive core, in particular made of one suitable ferrite known. This type of chokes eliminates im Normally only the so-called asymmetrical disturbances. In addition, symmetrical ones also occur in interfering devices Malfunctions that may have to be eliminated by additional measures, e.g. rod core chokes. The effort is therefore hc and it was to find a solution that was both asymmetrical as well as eliminating the symmetrical interference with one component.

Die Lösung wurde gefunden in einer stromkompensierten Ringkerndrössel mit erhöhter Streuinduktivität, die durch einen speiche förmig in den Ringkern eingefügten magnetischen Bypass erreicht wird.The solution was found in a current-compensated toroidal drill with increased leakage inductance, which is achieved by a spoke-shaped magnetic bypass inserted into the toroidal core will.

Diese Anordnung, bei der der magnetische Widerstand des sogen. Bypasses je nach Anordnung an das Entstörverhalten durch Auswal: eines entsprechenden magnetischen Materials in großen Grenzen 1 liebig angepaßt werden kann, weist erfindungsgemäß vorteilhaft« Eigenschaften auf.This arrangement, in which the magnetic resistance of the so-called. Bypasses depending on the arrangement of the interference suppression behavior by selecting: a corresponding magnetic material within large limits 1 can be adapted at will has advantageous properties according to the invention.

Zunächst sei in Gegenüberstellung der Feldlinienverlauf der hei kömmlichen und der erfindungsgemäßen Drossel in Abb. 1 und Abb, au,f gezeigt. - ·In opposition initially was the field lines of the hot conventional and the throttle of the invention in Fig. 1 and Fig, au, f shown. - ·

Mit dieser Anordnung wird erreicht, daß die Impedanz der Wicklungen sich nicht ändert, jedoch eine die symmetrischen Störungen beseitigende Streuinduktivität entsteht.With this arrangement it is achieved that the impedance of the windings does not change, but the symmetrical one Leakage inductance eliminates interference.

Der Bypass zum Schließen der Feldlinien wird durch Ausbildung des Ringkerns mit einer Speiche dargestellt, wobei der Luftspalt (5) durch entsprechende (Preß)-Formgestaltung erreicht wird.The bypass for closing the field lines is represented by the formation of the toroidal core with a spoke, whereby the air gap (5) is achieved by appropriate (press) -form design.

Ein weiterer Vorzug der erfindungsgemäßen Drossel ist, daß die räumlichen Abmessungen bei gleichen sonstigen elektrischen Eigenschaften kleiner ausfallen.Another advantage of the choke according to the invention is that the spatial dimensions with the same other electrical properties turn out smaller.
