Apparatus for wirelessly transmitting power after confirming location of receiver and method thereof

Abstract

Disclosed are an apparatus for wirelessly transmitting power characterized by confirming the location of a receiver and transmitting wireless power to the confirmed location. More particularly, the apparatus for wirelessly transmitting power includes a beamformer configured to form beams with a first width and sequentially transmit the formed beams with the first width to different spaces that are physically separated from each other and at least partially overlap; a reception part configured to receive reception power values corresponding to the transmitted beams with the first width; a calculator configured to calculate a phase of the receiver using a plurality of high reception power values based on magnitudes of the received reception power values; and an estimator configured to estimate a location of the receiver based on the calculated receiver phase, wherein wireless power is transmitted to the estimated receiver location.
