Power Transfer Unit of a System for Inductive Power Transfer, a Method of Manufacturing a Primary Power Transfer Unit and of Operating a Primary Power Transfer Unit

A power transfer unit of a system for inductive power transfer, wherein the power transfer unit comprises a winding structure, wherein the power transfer unit further comprises at least one flux guiding means for guiding a magnetic flux of an electromagnetic field,

• wherein
• the at least one flux guiding means comprises or provides at least one low reluctance section with a first reluctance and at least one high reluctance section with a second reluctance, wherein the second reluctance is higher than the first reluctance, wherein the at least one high reluctance section extends parallel to a lateral axis of the winding structure, and
• wherein
• a geometric centre or centreline of the at least one high reluctance section is arranged within a centre plane between two adjacent poles provided by the winding structure.
