According to one embodiment of the invention, a 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 receiverand 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. 根据实施例，用于无线充电系统的发射机包括：多个锁相环，用于输出单相位的多个功率信号；多个天线，用于向接收机发送从上述多个锁相环传递的多个功率信号；以及控制器，以从上述接收机接收的接收信号强度指示为基础来确定与上述接收机有关的特定频率，并基于上述特定频率，在预先设定的范围的特定频带内，将上述多个锁相环各自的输出频率控制成不同。
