First Claim
Patent Images
1. A wireless multi-charging method of a power transmitter that wirelessly transmits power, the method comprising:
- sensing a first power receiver;
increasing a transmission power required for charging the first power receiver when sensing the first power receiver;
sensing a second power receiver;
decreasing the transmission power required for suspending charging of the first power receiver when sensing the second power receiver; and
increasing the transmission power required for simultaneously charging both the first power receiver and the second power receiver.

11. A power transmitter for wireless multi-charging, the power transmitter comprising:
-
a resonator configured to generate a Radio Frequency (RF) field, and to wirelessly transmit power to a first power receiver and a second power receiver through the RF field; a sensor unit configured to sense the first power receiver and the second power receiver; and a controller configured to increase a transmission power to charge the first power receiver when the first power receiver is sensed, decrease the transmission power to suspend charging the first power receiver when the second power receiver is sensed, and increase the transmission power to simultaneously charge the first power receiver and the second power receiver. - View Dependent Claims (12, 13, 14, 15)
