60W 28KHZ Ultrasonic Sound Generator Circuit Ultrasonic Pcb Drive Board Generator For Ultrasonic Cleaner

Aiming at the characteristics of narrow working frequency band and fast frequency tracking speed in low-power ultrasonic applications, a frequency automatic tracking scheme combining fuzzy control intelligent algorithm and direct digital frequency synthesis technology is proposed for low-power ultrasonic PCB drive circuit board. Based on experience, a fuzzy controller is developed to quickly track the working frequency, Adjust the driving frequency to near the resonant frequency. Subsequently, only direct digital frequency synthesis technology is used to fine tune the frequency, so that the power frequency operates at the resonant frequency point of the ultrasonic transducer
