[0025] The present invention provides an ultrasonic wireless power transmission system based on adaptive control, which includes an energy transmission part and an adaptive control part. The energy transmission part includes an ultrasonic power supply, a transmitting transducer, a receiving transducer and a receiving circuit to realize energy Wireless transmission from the transmitter to the receiver; the adaptive control part includes an energy management module, a signal feedback path and dynamic impedance matching to achieve closed-loop control and efficiency optimization of the system.
[0026] In the energy transmission part, the ultrasonic power supply converts direct current into high-frequency alternating current to drive the transmitting transducer. The transmitting transducer uses the inverse piezoelectric effect to convert the alternating current into ultrasonic waves and send it to the medium, which is transmitted to the receiving transducer through the medium. The rec...
