[Power amplifier application] Ultrasonic transducer static matching system

发布:2021-09-02

       Ultrasound is a mechanical wave with a frequency higher than 20KHz. It has the characteristics of strong directionality, strong carrying energy, and strong penetrating power. It can obtain relatively concentrated sound energy. Ultrasound interacts with the medium in the propagation process, which can be divided into the following four ultrasonic effects: mechanical effect, cavitation, thermal effect, and chemical effect. Different ultrasound effects can be used to apply ultrasound to different fields, and the device used to convert between ultrasound and other forms of energy is called an ultrasound transducer, which plays a vital role in ultrasound applications.

With the rapid development of piezoelectric ultrasonic transducers, they are used in different fields such as ultrasonic cleaning, ultrasonic processing, ultrasonic welding, ultrasonic medical treatment, ultrasonic testing, and so on. In the field of power ultrasonic applications, ultrasonic cleaning occupies most of the market. The power amplifier in the excitation source of the ultrasonic cleaning machine generates an alternating electrical signal to drive the piezoelectric ceramic sheet in the piezoelectric ultrasonic transducer to vibrate, generate ultrasonic waves, and realize energy conversion.

ATA-2000 series power amplifieris a power amplifier that can amplify AC and DC signals. The maximum differential output is 1600Vp-p (±800Vp) high voltage, which can drive high-voltage loads. It can be used in conjunction with mainstream signal generators and is widely used in the composition of excitation sources to achieve signal power amplification and drive ultrasonic transducers. Aigtek power amplifiers are also used in underwater communications, mems drives, sonar systems and many other fields.
