The purpose of frequency tracking model and performance optimization of low-frequency ultrasonic circuit board is to make the ultrasonic electrical signal output by the ultrasonic processing system track the resonance frequency of the upper ultrasonic transducer in real time, quickly and accurately. Aiming at the equivalent electrical circuit of the transducer near the resonance frequency, the electrical impedance model of the ultrasonic transducer is established. On this basis, the relationship between the resonance frequency of ultrasonic transducer and various parameters is analyzed.
