Abstract

A suppression choke arrangement is described, forming a structural unit having a single core of magnetic material, which arrangement can simultaneously attenuate and overcome both balanced and unbalanced interference in the current supply of electrical or electronic apparatuses. <IMAGE>

Description

Elektrische Störspannungsquellen erzeugen in den meisten Fällen sowohl (netz-)symmetrische als auch (netz-)asymmetrische Störungen. Um diese zu be­ seitigen, ist es bisher erforderlich gewesen, zwei verschiedene Drosselarten einzusetzen, und zwar eine stromkompensierte, vorzugsweise mit einem Ferrit­ ringkern aufgebaute Drossel zur Bedämpfung der symmetrischen Störungen und eine zweite Drossel zur Bedämpfung der asymmetrischen Störungen, die nicht stromkompensiert, mit einem zweiten (Ring-)Kern aus Metallpulver aufgebaut ist, Metallpulverkern deshalb, um die Sättigung zu vermeiden.In most cases, electrical interference voltage sources generate both (Grid) symmetrical as well as (grid) asymmetrical interference. To be this sided, it was previously necessary to use two different types of throttle use, namely a current-compensated, preferably with a ferrite Toroidal choke to dampen the symmetrical interference and a second choke to attenuate the asymmetrical interference that is not current-compensated, with a second (ring) core made of metal powder metal powder core to avoid saturation.

Diese bisher übliche Entstörmethode ist aufwendig und somit nicht nur viel Raum benötigend, sondern auch teuer.This previously common interference suppression method is complex and therefore not only a lot Requiring space, but also expensive.

Es konnte nun gefunden werden, daß mittels eines Bauteils, einer kombinierten Entstördrossel, beide Störkomponenten ausreichend bedämpft werden können. Diese kombinierte Entstördrossel weist folgende Merkmale auf:
Ein E-Kern mit entsprechend angepaßten magnetischen Querschnitten trägt auf den beiden Außenschenkeln je einen zwei- oder vierkammerigen Spulenkörper, der jeweils mit mindestens vier Anschlußstiften versehen ist. Diese Spulenkör­ per sind derart bewickelt, daß der eine eine stromkompensierte Wicklung auf­ weist, der andere zwei Wicklungen, die nicht kompensiert sind.It has now been found that both interference components can be adequately damped by means of one component, a combined interference suppressor. This combined suppressor choke has the following features:
An E-core with correspondingly adapted magnetic cross sections carries a two- or four-chambered coil body on each of the two outer legs, each of which is provided with at least four connecting pins. These spools are wound in such a way that one has a current-compensated winding, the other two windings that are not compensated.

Der Schenkel des E-Kerns, der die nicht kompensierte Wicklung aufnimmt, besitzt einen Luftspalt, damit der fließende Strom in diesem magnetischen Kreis keine Sättigung bewirken kann. Der Schenkel des E-Kerns, der die kompensierte Wick­ lung trägt, weist einen solchen Luftspalt nicht auf, da die Sättigung durch die Stromkompensation vermieden wird.The leg of the E core, which receives the uncompensated winding, has an air gap so that the current flowing in this magnetic circuit does not Can cause satiety. The leg of the E core, which the compensated Wick lung, does not have such an air gap, because the saturation through the current compensation is avoided.

Die beiden Teildrosseln werden in üblicher Weise über die gedruckte Schaltungs­ platine entsprechend verbunden, wobei die Möglichkeit besteht, noch einen X-Kondensator dazuzuschalten, um die Entstörwirkung zu optimieren.The two partial chokes are connected in the usual way via the printed circuit board connected accordingly, with the possibility of another Add the X capacitor to optimize the interference suppression.

Der konstruktive Aufbau der erfindungsgemäßen kombinierten Entstördrossel geht aus Fig. 1a und b hervor. The structural design of the combined interference suppression choke according to the invention is shown in FIGS. 1a and b.

Hierbei ist (1) der E-Kern, der an einem Außenschenkel einen Luftspalt aufweist, (2) die baugleichen Spulenkörper mit den Kammern (3), in denen die (nicht ge­ zeichneten) Wicklungen untergebracht sind, deren Enden jeweils an die Stifte (4) angelegt sind.Here, ( 1 ) the E core, which has an air gap on an outer leg, ( 2 ) the identical bobbins with the chambers ( 3 ), in which the windings (not shown) are housed, the ends of which are each connected to the pins ( 4 ) are created.

Die Pfeile deuten den magnetischen Fluß in den jeweiligen Teildrosseln an.
