It is difficult to control the feedback attempt and adjust the circuit parameters in the automatic frequency tracking system of low-power ultrasonic generator in the form of circuit board feedback. The step length and delay parameters of the frequency conversion of the ultrasonic generator of the utility model can be adjusted by software, which is very convenient, reflecting the function of hardware softening, so it has strong adaptability to various systems.
