Abstract:
(EN) The invention relates to a protection device for an inductive energy transmission system. A screen is provided between the primary coil and the secondary coil for inductive energy transmission, said screen being permeable to the magnetic field of the inductive energy transmission as well as reliably screening applied electric fields. For this purpose in particular, a suitable circuit path structure, in which no eddy currents form, can be provided.
(FR) La présente invention concerne un dispositif de protection pour un système de transfert d’énergie par induction. Un blindage est placé entre la bobine primaire et la bobine secondaire du système de transfert d'énergie par induction, ce blindage étant perméable aux champs magnétiques du système de transfert d'énergie par induction, mais protégeant de manière fiable contre les champs électriques produits. À cet effet, on peut prévoir en particulier une structure à pistes conductrices appropriée dans laquelle aucun courant de Foucault ne se forme.
(DE) Die vorliegende Erfindung schafft eine Schutzvorrichtung für ein induktives Energieübertragungssystem. Zwischen der Primärspule und der Sekundärspule einer induktiven Energieübertragung ist eine Abschirmung vorgesehen, welche zwar für die Magnetfelder der induktiven Energieübertragung durchlässig ist, jedoch auftretende elektrische Felder zuverlässig abschirmt. Hierzu kann insbesondere eine geeignete Leiterbahnstruktur vorgesehen sein, in welcher sich keine Wirbelströme ausbilden.
