High-voltage power supply for x-ray control of the structure of materials

Abstract
A high-voltage power supply, as an X-ray tube, is one of the main components of X-ray machines widely used in studying the structure of materials, assessing the internal structure of components and mechanisms, and non-destructive testing of technological processes. In monoblock-type devices, the X-ray tube and power supply are located in a common enclosure, while in cable-type setups, the X-ray emitter with the tube and the power supply are connected by a high-voltage cable. We present the results of research in creating a high-voltage stabilized power supply for X-ray tubes as a part of a cable-type apparatus. Electrical circuits and the design of the power supply based on a full bridge voltage inverter built on power bipolar transistors are developed. Adjustment of the output voltage and power of the source is carried out through PWM modulation of the rectified mains voltage applied to the primary winding of the high-voltage transformer. The use of a solid-state compound with increased thermal conductivity allowed us to use forced air cooling of the source and place it within the dimensions of the Rack Mount standard (4U form factor). The experience of the power supply operation in conditions of a large industrial enterprise has shown that its electrical and dimensional parameters provide the possibility of successful use in X-ray installations intended for the structure control of materials.
