Abstract

A wireless power transmitter to wirelessly transmit power applies a current or voltage to a transmitter coil based on an indication of coupling being in a predetermined range. The current or voltage which is applied causes the transmitter coil to transmit a high power (HP) DPING. A response to the HP DPING indicates that a wireless power receiver is located on a charging surface and a power signal is then transmitted to the wireless power receiver to charge or power an electronic device coupled to the wireless power receiver. Use of HP DPING improves the wireless power transmission performance including transmission area and interoperability of wireless power transmitters with low coupling to wireless power receivers.
