Title:
ELECTRONIC DEVICE AND METHOD FOR CONFIRMING POWER RECEPTION DEVICE BY ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/059899
Kind Code:
A1
Abstract:
According to various embodiments, an electronic device comprises: coils; power conversion circuits configured to receive direct current power, convert same into alternating current power, and output same to the coils; and a processor. The processor can be configured to: apply to the coils a ping signal of which a ping power section is repeated periodically and which has a plurality of ping power levels increasing in phases; confirm an SSP signal responding to the ping signal; and perform wireless power transmission by means of the coils on the basis of a ping power level in which the SSP signal is confirmed from among the plurality of ping power levels. Other embodiments can be possible.
