20130127410 | APPARATUS AND METHOD FOR CONTROLLING CHARGING POWER OF WIRELESS POWER RECEIVER - In an apparatus for adjusting charging power of a wireless power receiver, when one or more wireless power receivers require charging, it is determined whether the sum of required charging powers required by the one or more wireless power receivers exceeds maximum supplied power provided by a wireless power transmitter. When a result indicates that the sum exceeds the maximum supplied power, a control operation is performed to adjust the required charging power of each wireless power receiver. Therefore, it is possible to wirelessly charge each wireless power receiver without interruption. | 05-23-2013 |
