Non-destructive testing technology is an important non-destructive testing method, which is widely used in aviation, aerospace, nuclear power, petroleum and other industrial fields. In the non-destructive testing process, the high-voltage power amplifier, as a key device, plays an important role. The meaning and role of high-voltage power amplifiers in non-destructive testing will be introduced in detail below.
The role of high voltage power amplifiers
The high-voltage power amplifier is mainly responsible for amplifying the control signal and driving the actuator, so as to realize the scanning or detection of the detected object. It can increase the output voltage or current of the probe, thereby improving the sensitivity and resolution of nondestructive testing. In addition, the high-voltage power amplifier can also control the working frequency and pulse width of the probe to meet different non-destructive testing requirements.

Application of High Voltage Power Amplifier in Nondestructive Testing
Non-destructive testing technology is widely used in various industries, such as aviation, aerospace, nuclear power, petroleum, etc. Among them, the high-voltage power amplifier, as a key device, is mainly used in the following aspects:
Ultrasonic testing: In ultrasonic testing, a high-voltage power amplifier can drive an ultrasonic probe to generate high-energy ultrasonic signals, and receive reflected signals through the probe to detect internal defects and material states of the detected object. It can provide enough power and sensitivity to ensure the accuracy of non-destructive testing.
X-ray inspection: In X-ray inspection, the high-voltage power amplifier can drive the X-ray tube to generate high-energy X-rays, and receive the reflected signal through the detector to detect the internal structure and defects of the inspected object. It can provide stable high voltage output to ensure the normal operation of the X-ray source.
Electromagnetic detection: In electromagnetic detection, the high-voltage power amplifier can drive the electromagnetic probe to generate high-frequency electromagnetic field signals, and receive the reflected signals through the receiver to detect the defects and material properties of the detected object. It can provide sufficient power and frequency stability to ensure the accuracy of electromagnetic detection.

High-voltage power amplifier plays a very important role in non-destructive testing, and it can achieve the following functions:
Detect the internal structure and defects of metal materials: High-voltage power amplifiers can amplify the tiny signals in metal materials to a sufficiently large amplitude, so that the internal structures and defects of metal materials can be detected.
Detecting the physical properties of metal materials: high-voltage power amplifiers can amplify the physical quantities in metal materials (such as temperature, pressure, speed, etc.) to a sufficiently large amplitude, so that the physical properties of metal materials can be detected.
Detecting the quality of welded joints: The high-voltage power amplifier can amplify the tiny signals in the welded joints to a sufficiently large amplitude, so that the quality of the welded joints can be detected.
Detect internal structures and defects of pipes and containers: High-voltage power amplifiers can amplify tiny signals in pipes and containers to a sufficiently large amplitude, so that internal structures and defects of pipes and containers can be detected.
High-voltage power amplifier plays a vital role in non-destructive testing, it can improve the sensitivity and resolution of non-destructive testing, and ensure the accuracy and reliability of non-destructive testing.
