Claim 12:
13. A method for performing adaptive impedance matching by an electronic device, the method comprising;
performing first impedance matching on a wirelessly received power signal through a first impedance matching circuit;
performing second impedance matching on the first impedance-matched power signal through a second impedance matching circuit using one of a plurality of impedance values;
controlling to change an impedance value of the second impedance matching circuit to an impedance value learned using an impedance matching network model in accordance with a power and a frequency of the second impedance-matched power signal; and
converting a second impedance-matched power signal in an AC form to a power in a DC form for a battery according to the changed impedance value,
wherein the impedance matching network model is configured to sequentially acquire second impedance-matched power signals using the plurality of impedance values, identify a high power signal among the second impedance-matched power signals based on a comparison between powers of the second impedance-matched power signals, and change the impedance value of the second impedance matching circuit to the learned impedance value, which is an impedance value corresponding to the high power signal, among the plurality of impedance values.
