1. A secondary-sided arrangement of at least one secondary winding structure, wherein the secondary-sided arrangement comprises:
at least one phase line and one secondary winding structure per phase line, wherein the secondary-sided arrangement comprises at least two magnetically conducting elements;
at least one lateral outer magnetically conducting element and at least one inner magnetically conducting element;
wherein at least one secondary winding structure extends along a longitudinal axis of the secondary-sided arrangement;
wherein the at least one secondary winding structure comprises two or more subwinding structures which extend along the longitudinal axis;
wherein successive subwinding structures of the at least one secondary winding structure are arranged adjacent to one another along the longitudinal axis;
wherein at least one subwinding structure comprises at least one winding section which extends along the longitudinal axis and at least one winding section which extends along a lateral axis;
wherein the lateral axis is oriented perpendicular to the longitudinal axis;
wherein a length is measured along the longitudinal axis and a width is measured along the lateral axis; and
wherein
a length of the at least one inner magnetically conducting element is smaller than a length of the at least one lateral outer magnetically conducting element, wherein the at least one secondary winding structure is substantially arranged within a two-dimensional plane spanned by the longitudinal and lateral axes, wherein at least one section of at least one magnetically conductive element extends into or through a volume or area enclosed by the at least one secondary winding structure or by a subwinding structure of the at least one secondary winding structure.
