Abstract
An electronic device includes: coils; power conversion circuits configured to receive direct current (DC) power, convert the DC power into alternating current (AC) power, and output the AC power to the coils; and a processor. The processor is 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 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.
