APPARATUS AND METHOD FOR CONTROLLING CHARGING POWER OF WIRELESS POWER RECEIVER
First Claim
1. A transmission apparatus for adjusting charging power of a wireless power receiver, the transmission apparatus comprising:
- a power supply unit which outputs a power signal; and
a transmission controller which calculates a sum of required charging powers of one or more wireless power receivers when a data signal for wireless charging is received from the one or more wireless power receivers, and generates a charging power adjustment signal for adjusting the required charging power of each of the one or more wireless power receivers and transmitting the generated charging power adjustment signal to each of the one or more wireless power receivers, when the calculated sum exceeds maximum supplied power capable of being supplied by the transmission apparatus.

Abstract
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.
