In recent years, ultrasonic cleaning technology has been widely applied in many fields due to its advantages such as low cost, high degree of automation, and good cleaning effect. Ultrasonic power supply is the core part of ultrasonic cleaning machines. The ultrasonic circuit board design uses DSP as the main control chip, and a PI-DPLL frequency tracking system based ultrasonic cleaning machine test device has been designed. The experiment shows that the ultrasonic power supply controlled by PI-DPLL has a simple circuit, Good frequency tracking performance and high power input factor

In terms of frequency tracking in the design of ultrasonic circuit boards, a novel composite frequency tracking control strategy based on fuzzy control combined with digital phase-locked loop (fuzzy-PLL) is proposed to address the shortcomings of traditional frequency tracking methods. This strategy uses a fuzzy controller to find the resonant frequency of the load, and then uses a phase-locked loop frequency tracking circuit to accurately track the frequency, Always ensure that the transducer load operates at the resonant frequency. In terms of matching network selection, based on a detailed analysis of several tuning schemes, an improved series resonant matching network was ultimately selected, which meets the system’s requirements for impedance matching and improves the adaptability of the matching circuit to changes in transducer electrical parameters
