How does a piezoelectric ceramic amplifier drive a piezoelectric transducer?

“A transducer refers to a device capable of energy conversion, that is, a device that can convert one form of energy into another. An ultrasonic transducer is an energy conversion device that amplifies and converts an alternating electrical signal into an acoustic signal within an ultrasonic frequency through a piezoelectric ceramic power amplifier, or converts an external acoustic signal into an electrical signal. Among them, the transducer used to transmit sound waves is called a transmitter, and the transducer used to receive sound waves is called a receiver.

I believe that the small partners who usually pay attention to piezoelectric ceramic amplifiers, about how piezoelectric ceramic amplifiers drive piezoelectric transducers, today, the editor of Aigtek will share with you a pure dry goods, how piezoelectric ceramic amplifiers drive piezoelectric transducers, then Without further ado, let’s continue reading with the editor!

A transducer refers to a device capable of energy conversion, that is, a device that can convert one form of energy into another. An ultrasonic transducer is an energy conversion device that amplifies and converts an alternating electrical signal into an acoustic signal within an ultrasonic frequency through a piezoelectric ceramic power amplifier, or converts an external acoustic signal into an electrical signal. Among them, the transducer used to transmit sound waves is called a transmitter, and the transducer used to receive sound waves is called a receiver.

There are many types of ultrasonic transducers, which can be divided into piezoelectric ultrasonic transducers, magnetostrictive transducers, capacitive transducers and mechanical ultrasonic transducers according to the mechanism of energy conversion and different transducer materials. Wait. Two of the most common are magnetostrictive transducers and piezoelectric ultrasonic transducers. With the wide application of piezoelectric ceramic materials, magnetostrictive transducers are still used in some special fields, and have been gradually replaced by piezoelectric ultrasonic transducers.

Piezoelectric ceramic power amplifier drives piezoelectric ceramics:

The piezoelectric ultrasonic transducer is designed according to the principle of inverse piezoelectric effect of piezoelectric materials such as quartz, piezoelectric ceramics, piezoelectric composite materials and piezoelectric films. In order to maximize the advantages of piezoelectric ultrasonic transducers, at present, piezoelectric ceramic materials are the most commonly used piezoelectric transducer materials. In most experiments of driving piezoelectric ceramic transducers, piezoelectric ceramic power amplifiers play an important role in the process of driving transducers and converting electrical signals into acoustic signals.

The piezoelectric ceramic drive power amplifier ATA-2021H series has a maximum differential output of 200Vp-p (±100Vp) high voltage, which can drive high voltage loads. The voltage gain can be adjusted numerically, and the settings can be saved with one key. It provides convenient and concise operation options. It can be used with mainstream signal generators to achieve perfect signal amplification.

Input interface: standard BNC interface;

The input resistance is 50Ω and 5kΩ, which can perfectly match the high and low internal resistance signal sources.

The output is a banana socket, the maximum output voltage is 200Vp-p (±100V), and the output current is 500mA.

Monitor output interface: 1/100 Monitor: The voltage of this port is 1/100 of the output port, and the monitor port is a BNC connector, which can be directly connected to an oscilloscope for real-time monitoring of the output voltage.

The fast response characteristics of piezoelectric ceramic power amplifiers are not only reflected in bandwidth and slew rate, but also closely related to the maximum output current, voltage, and capacitance characteristics of the load. The main technical indicators for selecting a power amplifier are: voltage, current, power, bandwidth, slew rate, impedance, load, etc.
