METHOD FOR TRANSFERRING POWER FROM A WIRELESS POWER OUTLET TO A WIRELESS POWER RECEIVER AND CONTROL CIRCUIT FOR A WIRELESS POWER OUTLET

摘要

In a method for transferring power from a wireless power outlet to a wireless power receiver the outlet transmits a first-type ping signal transferring a burst of energy to the wireless power receiver. The outlet includes a detector able to detect when the receiver activates an over voltage protection mechanism. When the OVP is activated the outlet may transmit a lower energy second-type ping signal.
