1. An impedance control method of a wireless power transmitter configured to transmit power to at least one of target device, the method comprising:
generating power for charging by determining an impedance of a source resonator, and a signal level of a direct current (DC) voltage to be supplied to a power amplifier; transmitting the charging power to the at least one of target device through magnetic coupling; and adjusting the impedance of the source resonator based on at least one of the number of the at least one of target device and a device information of the at least one of target device. |
