Abstract:
An inductive device including a first and second concentric winding wound around a center axis of the inductive device, where the second winding is placed outside of the first winding and provided in two separate parts a first upper part and a second lower part, wherein there is an opening between the first and second parts of the second winding and the first winding has a first winding connection that passes through said opening, the inductive device further including a concentric electric shielding element around the center axis and stretching all the way between the upper and the lower part of the second winding, the shielding element including a metal shield layer.
