120W 28KHZ Piezoelectric Ultrasonic Cavitation Generator Pcb Board For Ultrasonic Cleaner

120W 28KHZ Piezoelectric Ultrasonic Cavitation Generator Pcb Board For Ultrasonic Cleaner

The purpose of low-power ultrasonic PCB drive circuit board frequency tracking is to use feedback technology to adjust the output frequency of the ultrasonic generator to match the resonant frequency of the transducer, so that the transducer always works in the optimal state. There are two methods for frequency tracking of traditional ultrasonic power sources: acoustic tracking and electrical tracking. Currently, most tracking methods use electrical tracking. This method is divided into current feedback method, impedance bridge method, and phase-locked loop method.
