Abstract
A combined inductive power receiving system and method for selectively providing at least one of power and communication reception. The combined inductive power receiving system comprises at least one inductive power receiver module configured to couple with at least one Near Field Communication (NFC) module possibly using a combined communication antenna. The inductive receiver module may comprise a power reception circuit operable to receive power from a secondary inductor and to provide power to an electric load; a selection switch operable to allow transmission of wireless power from the secondary inductor to the power reception circuit; and a matching circuit operable to filter transmission of NFC signals to the NFC reader module.

24. A method for charging an electrochemical cell of a mobile communication device, said mobile communication device comprising a near field communication antenna, a near field communication circuit, a power receiving circuit and a switching unit operable to selectively connect said communication circuit or said power receiving circuit to said near field communication antenna, the method comprising the steps:
-
providing a rectification unit wired to said electrochemical cell; connecting said power receiving circuit to said near field communication antenna; and bringing said near field communication antenna into the vicinity of an operating inductive power outlet; such that a secondary voltage, induced in said near field communication antenna, is rectified by said rectification unit thereby providing a charging voltage for said electrochemical cell.
