WIRELESS POWER TRANSMISSION SYSTEM Russian patent published in 2020 - IPC G06F1/32 H02J7/00 H02J50/23 

FIELD: energy transmission systems.

SUBSTANCE: invention in general relates to energy transmission systems and charging devices for storage batteries and, in particular, to wireless transmitter and wireless receiver of electromagnetic energy. Wireless electromagnetic energy transmitter comprises: a controller and a phased antenna array having a plurality of electromagnetic grid transceivers, each for transmission of electromagnetic energy transmission signal, wherein transceivers are adaptively phased by controller, in order to transmit its respective power transmission signals with the corresponding selected phase. Each transceiver further operates to receive multi-beam calibration signals from the device, which must be charged with electromagnetic energy transmission signals, and phase detection, with which each multi-beam calibration signal is received by corresponding transceiver. Controller is further configured to adjust the corresponding selected phase for use in transmitting the corresponding power transmission signal to the corresponding determined phase, wherein corresponding determined phase is based on corresponding detected phase, wherein corresponding determined phase indicates optimum phase for energy transfer signal, which must be transmitted to device to be charged.

EFFECT: technical result consists in provision of higher efficiency of energy transfer to device, which should be charged.
