Description

BeschreibungDescription

Weichmagnetischer Schalenkern zur Aufnahme von Wicklungen.Soft magnetic shell core for holding windings.

Schalen- oder Ringkerne werden üblicherweise so bewickelt, daß der magnetische Fluß den Kern nur in einer Richtung durchflutet.Shell or toroidal cores are usually wound in such a way that the magnetic flux flows through the core in only one direction.

Die zunehmende Verkleinerung elektronischer Baugruppen, sowie der vielfälltige Einsatz von Induktivitäten, erfordert eine noch effektivere Ausnutzung des Kernmaterials; da ein erheblicher Platzbedarf (Gewicht) im Vergleich zu anderen Bauteilen benötigt wird,The increasing miniaturization of electronic components, as well as the diverse use of inductors, requires an even more effective use of the core material; since a considerable amount of space (weight) is required compared to other components,

In vielen Fällen, wie z. B. bei Leistungsanwendungen, kann dieses Problem nicht durch die Erhöhung der Taktfrequenz beseitigt werden. Es muß also eine andere Abhilfe gesucht werden.In many cases, such as power applications, this problem cannot be solved by increasing the clock frequency. So another solution must be found.

Der im Schutzanspruch 1 angegebeben Erfindung liegt das Problem zugrunde, einen Schalenkern so zu bewickeln, daß dieser in zwei Richtungen durchflutet wird.The invention specified in claim 1 is based on the problem of winding a shell core in such a way that it is flooded in two directions.

Dieses Problem wird mit den in Schutzansruch 1 aufgeführten Merkmalen von Innen- und Ringwicklung gelöst.This problem is solved with the features of inner and ring winding listed in claim 1.

Mit der Erfindung wird erreicht, daß der Schalenkern in zwei Richtungen magnetisiert wird. Die beiden voneinander unabhängigen Magnetfelder durchfluten den Kern gemeinsam und stehen in einem Winkel von 90° zueinander. Dadurch ergibt sich eine Einsparung von Kernvolumen und Kupfer.The invention ensures that the shell core is magnetized in two directions. The two independent magnetic fields flow through the core together and are at an angle of 90° to each other. This results in a saving of core volume and copper.

Eine weitere vorteilhafte Anwendung bietet die individuelle Wicklungsanordnung. Es ist z. B. möglich den Ringkern als Trafo zu bewickeln, während die innere Wicklung als Drossel gedacht ist.Another advantageous application is the individual winding arrangement. For example, it is possible to wind the toroidal core as a transformer, while the inner winding is intended as a choke.

Ein Ausführungsbeispiel der Erfindung wird anhand der Figur 1 erläutert. Es zeigt:An embodiment of the invention is explained with reference to Figure 1. It shows:

Fig. 1 einen Schalenkern mit Innen- und Ringwicklung.Fig. 1 a pot core with inner and ring winding.
