Abstract:
A wireless power transferring device, a wireless power transferring unit and a wireless power receiving unit for transferring and receiving power. The power receiving unit includes an induction coil adapted to be subjected to an alternating magnetic field so that an alternating current is induced in the induction coil, a receiving concentrator core adapted to concentrate the magnetic field wherein the receiving concentrator core is surrounded by a medium, and a receiving guide member arranged to provide a smooth transition for the magnetic field between the medium and the concentrator core, and abutting the receiving concentrator core. The receiving guide member has a magnetic permeability in the range between the magnetic permeability of the receiving concentrator core and the medium.
