SYSTEM AND METHOD FOR PROVIDING COMMUNICATIONS IN A WIRELESS POWER SUPPLY
摘要
A wireless power transfer system with a remote device having a communication transmitter configured to initiate communications with a framing pulse to prevent noise from being mistaken for legitimate data. The communication system may employ a bi-phase modulation scheme, and the framing pulse may be generated to present no transitions in the communication signal during a specified period of time. The communication transmitter may produce the framing pulse by applying a load in the remote device. The present invention also provides a method for transmitting communication signals in a wireless power supply system including the general steps of: (a) preceding each communication with a framing pulse configured to present a bit sequence that does not exist in legitimate data communications, (b) maintaining the framing pulse for a period of time sufficient to effectively "reset" the communications receiver and (c) transmitting communications following the framing pulse.
