  • High efficiency wireless charging system and its control method
    Patent number: 9419469
    Abstract: A control method for a wireless charging system has steps of performing impedance matching on an antenna of the wireless charging system; tracing an optimal frequency point by sending a sensing signal with a default transmission frequency, and calculating a transmission efficiency of the sensing signal; determining whether the transmission efficiency meets a transmission requirement. When the transmission efficiency does not meet the transmission requirement, repeats the previous steps with another default transmission frequency until the transmission efficiency meeting the transmission requirement. When the transmission efficiency meeting the transmission requirement, the default transmission frequency is defined as the optimal frequency point for charging.
