System and method for power transfer control based on available input power

摘要

The present invention employs system and method in for distinguishing between power capabilities of various external power sources and a system that can communicate the identified power capabilities to the secondary side of the wireless power transfer system. Once the secondary side of the wireless power transfer system receives the power capability information, it adjusts the current available for a payload in accordance with the information received on power source capabilities.
