WIRELESS INDUCTIVE POWER TRANSFER Russian patent published in 2018 - IPC H02J5/00 H02J50/10 

FIELD: electrical equipment.

SUBSTANCE: invention relates to electrical equipment. Power transmitter (101) comprises receiver (203) for receiving data messages, load modulated on the wireless inductive power signal and broadcast transmitter (205) broadcasting on a broadcast communication channel. Energy receivers (105) contain transmitter (505) for modulating the load of a data message on a power signal. Energy transmitter (101) contains communication controller (207), which broadcasts the first indications indicating that a wireless inductive power signal is available for modulation with a load over a time interval. First power receiver comprises broadcast receiver (507) receiving first indications from the power transmitter (101) and transmission controller (509) aligning transmissions of data messages with received first indications. Invention may improve communication for scenarios where one power transmitter simultaneously supports a plurality of power receivers.

EFFECT: improved performance and operation of a wireless power transfer system is provided due to wireless power transfer system that includes power transmitter (101) arranged to provide power transfer to a plurality of power receivers (105, 109) via a wireless inductive power signal.
