Abstract: Disclosed is a transmitter used in a wireless charging system. The transmitter includes at least one phase locked loop (PLL) that outputs a power signal, a first antenna that transmits the power signal transmitted from the at least one PLL to at least one receiver in an RF scheme, a second antenna that transmits the power signal to the at least one receiver in one of a magnetic resonance scheme and a magnetic induction scheme, and a controller that selectively drives at least one of the first and second antennas.

Abstract: Disclosed is a transmitter used for a wireless charging system. The transmitter includes a plurality of phase locked loops (PLLs) that outputs single-phase power signals, a plurality of antennas that transmits power signals transmitted from the plurality of PLLs to a receiver, and a controller that determines a specific frequency for the receiver based on a signal strength indication (RSSI) received from the receiver and allows output frequencies of the plurality of PLLs to be different from each other in a specific frequency band preset based on the specific frequency.
