220V 120W ultralydgenerator kretskort tilpasset 60W 40Khz transduser ultralyd rengjøring PCB montering

The design of PCB circuit of low-frequency ultrasonic circuit board is the key technology in the application of corresponding ultrasound, and its impedance matching has always been the focus of research. With the ambient temperature and the aging of components, the resonance frequency of the load transducer drifts, resulting in the decline or even stop of output energy, which is limited in application. Based on the research of ultrasonic power supply, combined with digital control technology, a digital ultrasonic power supply is designed based on frequency tracking and DC power regulation.
