Wireless power multi-charging method and power transmitter

摘要

A wireless multi-charging method of a power transmitter 100 that wirelessly transmits power includes sensing a first power receiver 200, increasing a transmission power required for charging the first power receiver 200, sensing a second power receiver, decreasing the transmission power required for suspending charging of the first power receiver, and increasing the transmission power required for simultaneously charging both the first power receiver and the second power receiver.
