More Information
Summary:A wireless power transmission device includes a main body, a first transmitter coil and a second transmitter coil. The second transmitter coil is stacked over the first transmitter coil. If the wireless power transmission device is operated in a detecting mode, a magnetic flux is generated by the first transmitter coil and oriented in the direction toward the top surface of the main body. The magnetic flux is attenuated by the overlying second transmitter coil. Consequently, the electromagnetic wave is inhibited. If the wireless power transmission device is operated in a charging mode, both the first transmitter coil and the second transmitter coil are controlled to transmit magnetic fluxes. Since the intensity of the electric power is increased, the charging efficiency is enhanced.
