I. Introduction 
The development of material processing technologies plays an important role in promoting modern industrial progress. As a key device, high-voltage power supplies are widely used in various material processing processes, such as thin film deposition, surface modification, and electrostatic dust removal. The performance parameters of high-voltage power supplies, including output voltage stability, waveform characteristics, and control accuracy, directly affect the effect and efficiency of material processing. In recent years, with the continuous emergence of new materials and new processes, the application research of high-voltage power supplies in material processing has also made remarkable progress.
II. Key Applications of High-Voltage Power Supplies in Material Processing 
1. Applications in Thin Film Deposition Technology 
In chemical vapor deposition (CVD) and physical vapor deposition (PVD) and other thin film deposition technologies, high-voltage power supplies are used to generate plasmas or provide accelerating electric fields. By precisely controlling the output parameters of high-voltage power supplies, the thickness, composition, and structure of thin films can be precisely regulated. For example, using high-frequency high-voltage power supplies to generate strong electric fields can increase the plasma density, thereby accelerating the thin film deposition rate and improving the compactness and uniformity of the thin films.
2. Applications in Surface Modification Technology 
Plasma surface modification is an important means to improve the surface properties of materials, such as enhancing the wear resistance, corrosion resistance, and biocompatibility of materials. High-voltage power supplies provide energy for the plasma generator. By adjusting parameters such as voltage and frequency, the energy density and chemical activity of the plasma can be controlled. Studies have shown that appropriate settings of high-voltage power supply parameters can form specific functional layers on the material surface, thereby significantly improving the surface properties of the materials.
3. Applications in Electrostatic Dust Removal Technology 
Electrostatic dust removal is a commonly used technology in industrial waste gas treatment. High-voltage power supplies generate high-voltage electric fields, causing dust particles to be charged and adsorbed onto electrodes, thus realizing the separation and collection of dust. Efficient high-voltage power supplies can provide stable electric field strength and improve dust removal efficiency. At the same time, by optimizing the waveform and voltage regulation mode of high-voltage power supplies, electrode corrosion and dust accumulation can be reduced, extending the service life of the equipment.
III. Challenges and Development Trends of High-Voltage Power Supply Technologies in the Field of Material Processing 
Although high-voltage power supplies have achieved many results in material processing, there are still some challenges. For example, how to further improve the stability of the output voltage to meet the needs of higher-precision material processing processes; how to reduce the volume and weight of the power supply to achieve miniaturization and portability of equipment; and how to reduce energy consumption and improve energy utilization efficiency, etc. 
In the future, the application of high-voltage power supply technology in the field of material processing will develop in the directions of intelligence, high efficiency, and environmental protection. Intelligent control systems can automatically adjust power supply parameters according to the real-time needs of material processing; the application of efficient power supply topological structures and component technologies will further improve energy conversion efficiency; and the design concept of environmental protection will prompt high-voltage power supplies to reduce their impact on the environment during the material processing process.
IV. Conclusion 
The application of high-voltage power supplies in material processing is of great significance. With the continuous innovation and development of technology, high-voltage power supplies will be able to better meet the needs of the material processing field for high performance, high quality, and high efficiency, and promote the continuous progress of material processing technology.
