Abstract
A wireless power transmitter device that includes a transmitter circuit, a transmitter coil, a transmitter communication unit and a transmitter control unit is provided. The transmitter circuit generates a transmitting current. The transmitter coil receives the transmitting current to generate an electromagnetic field to induce a receiving current in a wireless power receiver device. The transmitter communication unit is configured to receive a report of a received power of the wireless power receiver device therefrom. The transmitter control unit receives the report of the received power and determines whether a frequency splitting phenomena occurs according to the received power. When the frequency splitting phenomena occurs, the transmitter control unit adjusts at least one of a configuration of the transmitter coil and a configuration of the transmitter circuit or adjusts a transmitting frequency of the transmitting current.
