METHOD, ELECTRONIC DEVICE, AND STORAGE MEDIUM FOR PERFORMING ADAPTIVE IMPEDANCE MATCHING

WIPO Patent Application WO/2020/204408

A1

The present disclosure relates to an artificial intelligence (AI) system which simulates functions such as cognition, judgment, and the like of the human brain by utilizing machine learning algorithms such as deep learning and the like, and to an application thereof. According to various embodiments, an electronic device may comprise: a first impedance matching circuit which performs a first impedance matching on a power signal wirelessly received from a wireless power transmission device; a second impedance matching circuit which performs a second impedance matching on the first impedance-matched power signal using any one impedance value among a plurality of impedance values; a control circuit which controls to change an impedance value of the second impedance matching circuit to an impedance value learned by using an impedance matching network model, corresponding to a power and a frequency of the second impedance-matched power signal; and a power conversion circuit which converts a second impedance-matched AC type power signal into DC type power for a battery according to the changed impedance value. Other embodiments are possible.
