3000W Digital Piezoelectric Ultrasonic Generator Ultrasonic Cleaning Transducer Signal Generator

3000W Digital Piezoelectric Ultrasonic Generator Ultrasonic Cleaning Transducer Signal Generator

The purpose of this utility model is to provide a separately excited swept frequency ultrasonic generator, which can significantly improve power output and conversion efficiency by adopting PWM control. The utility model is a separately excited swept frequency ultrasonic generator, which includes a rectification circuit, a filtering circuit, an inverter, a power switch, and a transducer connected in sequence. The utility model is characterized in that it also includes an amplification circuit connected to the transducer, which amplifies the voltage and transmits it to the comparator; The other input end of the comparator is simultaneously connected to the given circuit, and the output end of the comparator is connected to an operational amplifier; The operational amplifier outputs a signal to a PWM (Pulse Width Modulation) controller, which is connected to another input for frequency regulation. The PWM controller controls the voltage and drives the power switch through a driver.
