METHOD FOR MANAGING A WIRELESS POWER TRANSFER FROM AN EMITTER TO A RECEIVER, AND CORRESPONDING EMITTER

Method for managing contactless energy transfer from a transmitter (1) to a receiver (2) mutually coupled, comprising generation by the transmitter (1) of a magnetic field from a control at a control frequency of a resonant switching circuit (100, 103), communication of information by the receiver (2) comprising a modulation of said magnetic field, detection by the transmitter of said modulation so as to extract said information and an adjustment of said control frequency as a function of said information received. Said detection of the modulation comprises detection (11, 14) of variations in the control frequency.
