Abstract

In this paper, a new type of non-metallic ultrasonic transmitting circuit is designed. This circuit uses the principle of flyback pulse excitation, The charging and discharging time of RC circuit is controlled by a frequency adjustable pulse output from Double core system, so that the transmitting voltage and radio frequency rate can be adjusted flexibly. By establishing the circuit model of the ultrasonic transmitting circuit and making the actual circuit, it is proved that the circuit can generate the ultrasonic pulse excitation signal with adjustable frequency and amplitude, thus improving the common problem that the transmitting efficiency of the probe in the traditional circuit is lower than the actual one, and improving the transmitting efficiency of the probe. Finally, the experiment was verified and the effect was good.
