摘要：A wireless power transmitting device may transmit power wirelessly to awireless power receiving device. The wireless power receiving device may be a portable
electronic device with an array of wireless power receiving coils that receive wirelesspower from wireless power transmitting coils in the wireless power transmitting device.Each receiving coil in the array of wireless power receiving coils may be coupled to arespective rectifier. Control circuitry of the wireless power receiving device may beconfigured to determine which rectifiers to enable for synchronous rectification. Thecontrol circuitry may be configured to enable at least one rectifier based on thealternating-current voltages produced by each coil in the array of receiving coils. Thecontrol circuitry may also be configured to enable at least one rectifier based on theoutput current from each rectifier.
