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.
