Abstract

A new type of non-metallic ultrasonic transducer driving system is designed in this paper.Based on the analysis of the traditional ultrasonic transmitting circuit, a new type of ultrasonic transmitting circuit is designed by using the principle of inductance energy storage to generate high power pulse.The design uses the FET as the switching control component.Compared with the traditional capacitive ultrasonic transmitting system, the whole circuit design has the advantages of high security and no need to provide DC high voltage power supply. It also has the advantages of small size and easy adjustment of driving waveform parameters.The system outputs a trigger pulse signal through the two-core system to control the operating state of the entire circuit.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.Finally, experimental verification is carried out, the effect is good, and the hidden danger of safety is eliminated.
