Application of Power Amplifier in Ultrasonic Atomization

Ultrasonic atomizers are divided into two categories: hydrodynamic type and electro-acoustic transducer type.

Ultrasonic atomization is the process of using ultrasonic energy to make liquid form fine droplets in the gas phase, that is, ultrasonic waves are generated on the vibrating liquid surface, and the vibration peak formed by the amplitude separates and breaks the droplets from the surface. As the ultrasonic frequency increases, the atomized droplets are getting finer and finer. Generally, fine droplets can be obtained under the action of the vibration frequency of the ultrasonic wave.

Ultrasonic atomizers are divided into two categories: hydrodynamic type and electro-acoustic transducer type. The electro-acoustic transducer type ultrasonic atomization uses a transducer to convert high-frequency electromagnetic oscillations into mechanical oscillations of the liquid, so that the liquid is broken into mist. In this process, the power amplifier amplifies the voltage excitation to drive the ultrasonic transducer. The other is that the liquid flows to the surface of the ultrasonic transducer and forms a thin liquid layer. The thin liquid layer excites surface tension waves under the action of ultrasonic vibration. When the amplitude of the vibrating surface reaches a certain value, the liquid droplets fly from the wave crest. Out and form atomization.

The ATA-2000 series independently developed by Aigtek is 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, and the voltage gain is digitally adjustable. At the same time, the output of the dual-channel high-voltage amplifier can also be adjusted synchronously, and can be used with mainstream signal generators to achieve perfect signal amplification. It is widely used in the research field of ultrasonic atomization.
