WIRELESS INDUCTIVE POWER TRANSFER |
摘要 |
A wireless power transfer system includes a power transmitter (101) arranged to provide a power transfer to a plurality of power receivers (105, 109) via a wireless inductive power signal. T power transmitter (101) comprises a receiver (203) for receiving data messages, load modulated on the wireless inductive power signal and a broadcast transmitter (205) broadcasting on a broadcast communication channel. The power receivers (105) comprise a transmitter (505) for load modulating data message on the power signal. The power transmitter (101) comprises a communication controller (207) which broadcasts first indications indicative of the wireless inductive power signal being available for load modulation in a time interval. A first power receiver comprises a broadcast receiver (507) receiving first indications from the power transmitter (101) and a transmission controller (509) aligning transmissions of data messages with received first indications. The invention may improve communication for scenarios where one power transmitter simultaneously supports a plurality power receivers. |
