Samenvatting

A shielded inductive power transfer unit (10,20 30,40) comprising a winding of a first coil (13,34,44) arranged for power transfer and a shielding member (60,70) arranged for covering at least a part of a first surface of the first coil in a direction of power transfer. The shielding member comprises a plurality of elongate electrically conductive strips (11) arranged for spanning an area all along the winding of the first coil, wherein the plurality of conductive strips have longitudinal axes are arranged parallel to the surface. The first coil defines a substantially void central (25) area about the first winding axis, wherein a part of the shielding member overlapping the central area (25) is essentially void of electrically conductive shielding material.
