INDUCTIVE WIRELESS TRANSMISSION OF POWER WITH SYNCHRONIZED MEASUREMENT OF POWER Russian patent published in 2020 - IPC H02J50/60 H02J7/02 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. Disclosed is an inductive wireless power transmitter for transmitting an inductive wireless power signal to at least two inductive wireless power receivers. Power transmitter coordinates communication with power receivers in time intervals. It allocates time interval of measurement for synchronized power measurement by power transmitter and power receivers. During the measurement time interval, the power transmitter measures the power it transmits. After the end of the measurement time interval, it receives the measured values of the received power from the power receivers. Based on measured transmitted power and received power it determines value of lost power. If the value of the lost power exceeds a threshold value, it reduces the power of the inductive wireless power signal.

EFFECT: technical result consists in enabling detection of foreign objects using one inductive wireless power transmitter transmitting power to multiple wireless power receivers.
