Abstract
A power transfer unit of a system for inductive power transfer, wherein the power transfer unit includes a winding structure, and at least one flux guiding means for guiding a magnetic flux of the electromagnetic field, wherein the at least one flux guiding means provides at least one low reluctance section with a first reluctance and at least one high reluctance section with a second reluctance, and the second reluctance is higher than the first reluctance. Also, a method of manufacturing a power transfer unit and a method of operating a power transfer unit.
