135Khz 900W Dual Frequency High Power Ultrasonic Sound Generator Adjustable 20-40Khz Converts Transducer Power Supply

1. The sound field distribution and energy transfer process of the dual frequency ultrasonic power supply are calculated according to the relevant formula. Theoretically, the dual frequency switching mode can effectively eliminate the influence of standing waves. High frequency ultrasonic can deeply clean the pollutants in the gaps of objects. Low frequency ultrasonic can clean the pollutants on the surfaces of objects. The dual frequency cleaning mode is more efficient and cheaper.
2. Aiming at the matching problem of dual frequency ultrasonic power supply, the impedance characteristics of dual frequency transducer are analyzed, two matching circuits are designed according to the test parameters, and electromagnetic relay is used to switch the matching circuit, and the calculation method of matching circuit parameters of transducer is described.
3. As for the speed and accuracy of the ultrasonic power supply, this paper uses DDS digital synthesis frequency technology to achieve frequency output
