ABSTRACT: In this paper, a high frequency driving circuit of surface acoustic wave transducer has been designed to separate oil from oil/water mixed droplet. The transmission frequency of the surface acoustic wave transducer driving circuit can be up to 1 MHz. The transmit frequency of conventional ultrasonic driving circuit is mostly 40 kHz. However, the high transmit frequency driving circuit presents a good stability and accuracy. By establishing the surface acoustic wave driving circuit model, the actual circuit and debugging verification, the driving circuit can excite the frequency signal required for the experiment. Thus, the surface acoustic wave driving circuit could provide necessary technical support for application in other fields.
