Abstract

A wireless power receiver (6) for receiving a power signal over an inductive coupling (300) from a power transmitting circuit (100) comprising a voltage generator (101) and for passing it to a load (800), the wireless power receiver (6) comprises: - a resonator (601, 602, 603) for receiving a power signal over the inductive coupling (300), the resonator (601, 602, 603) being suitable for converting a changing magnetic flux at its input port to an AC voltage at its output port; - energy storage means (601, 602) comprising at least one inductive component (601) and at least one capacitive component (602) for storing energy comprised in the power signal received by the resonator (601, 602, 603); and - a rectifying and regulating circuitry (610) for rectifying and regulating the received power signal before passing it to a load (800). The improvement is characterized in that the rectifying and regulating circuitry (610) comprises a buck regulator (611, 612, 613, 614, 615, 616) that is configured to carry out impedance matching between the load (800) and the resonator (601, 602, 603). The patent application comprises also an independent patent claim for an improvement in the method for operating a wireless power receiver.
