Sweep Type Resonant Frequency Tracking for Dual Ultrasonic Transducers Under Water

Ultrasound transducer can convert electrical energy to mechanical energy, and vice versa, but the efficiency will be limited by the driving frequency. This paper proposes the sweep type resonant frequency tracking for dual ultrasonic transducer system. The result shows that this method can detect the driving frequency of maximum efficiency and increase the power transfer.
