  • Patent number: 11894689
    Abstract: The power supply system of the present invention includes a wireless electricity transmitter and a wireless electricity receiver transmitting electricity by electromagnetic coupling. The wireless electricity receiver is further connected to a vibrator of a vibrating processing apparatus to transmit electricity thereto. The wireless electricity transmitter has a controller to monitor the operating voltage and the operating current of the transmitter, and alternates the oscillation frequency of the operating voltage according to the phase difference between the operating voltage and the operating current. Thereby, the oscillation frequency may approach the resonance frequency of the vibrator in order to improve the efficiency of electricity transmission. Also, the distance between the wireless electricity transmitter and the wireless electricity receiver can be increased.
