Abstract
A power transmitter and method are provided for wireless multi-charging. A power transmitter includes a resonator configured to wirelessly transmit power to one or more power receivers; and a controller configured to increase a transmission power of the resonator to charge a first power receiver when the first power receiver is located in a charging area of the resonator; decrease the transmission power of the resonator when a second power receiver is located in the charging area of the resonator; and increase the transmission power of the resonator to charge both of the first power receiver and the second power receiver.
