600W Digital Display Piezo Ultrasonic Cleaning Transducer Driver Board PCB Driver Circuit

The low-power ultrasonic PCB circuit board operates in a frequency sweep mode. After the frequency sweep is completed, the ultrasonic PCB circuit board starts working at the center of the resonant frequency, which is determined by the circuit structure and parameters. The series resonant frequency is determined by the l and c parameters in the series circuit, and is independent of the magnitude of the series resistance r and the applied excitation voltage. A low-power ultrasonic PCB circuit board will only resonate when the frequency of the external excitation is equal to the natural frequency of the circuit.
