110V 220V 200W Digital Display Ultrasonic Generator PCB Circuit Board Power Supply

The impedance characteristics of ultrasonic motors were analyzed on the 40KHZ ultrasonic circuit PCB circuit board. Based on this, the reasons and adverse effects of motor frequency drift were studied, and various methods for achieving frequency tracking were summarized. A self-excited swept frequency ultrasonic generator, comprising sequentially connected rectification circuits, filtering circuits, inverters, power switches, and transducers, as well as an amplification circuit connected to the transducer, which amplifies the voltage and transmits it to the comparator; The other input of the comparator is simultaneously connected to the given circuit
