Zusammenfassung

Komponenten im elektrischen Antriebsstrang von Kraftfahrzeugen müssen strenge Normen bezüglich der abgestrahlten Magnetfeldemissionen erfüllen. Hochvoltkabel spielen eine wichtige Rolle bei der Verteilung von beabsichtigten funktionalen und unbeabsichtigten parasitären Strömen. Diese Ströme führen zu gestrahlten Magnetfeldemissionen, die durch geometrische Konfigurationen beeinflusst werden.

Die Übertragungsfunktionen werden vorgestellt, um die Auswirkung der geometrischen Konfiguration der Stromschleifen auf die resultierenden Magnetfelder zu quantifizieren. Darüber hinaus werden sie auf der Grundlage der Verteilung von funktionalen und parasitären Strömen in geometrische Teilbereiche zerlegt.

Abstract

Components in the electric drive train of motor vehicles must meet strict standards with regard to radiated magnetic field emissions. High-voltage cables play an important role in the distribution of intended functional and unintended parasitic currents. These currents result in radiated magnetic field emissions that are influenced by geometric configurations.

The transfer functions are presented to quantify the effect of the geometric configurations of the current loops on the resulting magnetic fields. Furthermore, they are decomposed into geometric subareas based on the distribution of functional and parasitic currents.
