System and Method for wireless power transfer based on collaboration

摘要

The present invention relates to a collaborative wireless power transmission system and method capable of meeting human body stability standards while increasing energy transmission efficiency by distributing and transmitting at low power through a plurality of wireless power transmitters. And a plurality of wireless power transmitters that transmit RF power signals based on energy beamforming, wherein the plurality of wireless power transmitters receive beacon signals transmitted from the wireless power receivers, and the location of one and the same wireless power receivers The phase of the RF power signal is determined so that a phase difference between radio channels for the identified one wireless power receiver and a phase difference between other wireless power transmitters is calculated, so that a power signal of the same phase is received by the one wireless power receiver. Correct.
