< introduction >
 UV (ultraviolet) power supply is a key electronic equipment, which is used to provide electric energy for ultraviolet lamps. It plays an important role in many fields, including ultraviolet disinfection, ultraviolet curing, lithography and so on. This paper will introduce the principle, working mode and application of UV power supply in different fields.
 < the principle of UV power supply >
 The principle of UV power supply is to convert alternating current into direct current suitable for ultraviolet lamps. It usually consists of three main parts: input circuit, converter and output circuit. The input circuit is used to convert alternating current into direct current, the converter converts direct current into high-frequency alternating current, and the output circuit converts high-frequency alternating current into electric energy suitable for ultraviolet lamps. This conversion process can ensure the stable operation of the ultraviolet lamp and ensure that the ultraviolet generated by it has the required spectral characteristics.
 < how the UV power supply works >
 The working mode of UV power supply can be divided into two types: constant voltage and constant current. In constant voltage mode, the power supply will keep the output voltage unchanged and adjust the output current according to the demand of the load. This working mode is suitable for applications that need stable output voltage, such as ultraviolet disinfection. In constant current mode, the power supply will keep the output current constant and adjust the output voltage according to the demand of the load. This working mode is suitable for applications that need stable output current, such as ultraviolet curing.
 < application of ultraviolet disinfection >
 Ultraviolet disinfection is an effective sterilization method, which is widely used in medical treatment, food processing, water treatment and other fields. In ultraviolet disinfection, the UV power supply provides electric energy for the ultraviolet lamp to generate high-energy ultraviolet radiation, thus killing bacteria, viruses and other microorganisms. The constant voltage working mode of UV power supply can ensure the stable operation of UV lamp and ensure the consistency and reliability of disinfection effect.
 < application in ultraviolet curing >
 Ultraviolet curing is a rapid curing method of materials, which is widely used in printing, coating, lithography and other fields. In ultraviolet curing, UV power supply provides electric energy for ultraviolet lamp, which makes it produce high-energy ultraviolet radiation, thus triggering the curing reaction of photosensitive materials. The constant current working mode of UV power supply can ensure the stable operation of UV lamp and the consistency and reliability of curing effect.
 < application in lithography >
 Lithography is a lithography technology, which is widely used in semiconductor manufacturing, flat panel display and other fields. In lithography, the UV power supply provides electric energy for the UV mask aligner to generate high-energy UV radiation, thus forming the required pattern on the photoresist. The constant voltage working mode of UV power supply can ensure the stable operation of UV mask aligner and ensure the accuracy and consistency of patterns.
 < the development trend of UV power supply >
 With the continuous progress of science and technology, the supply of UV power is also developing. In the future, UV power supply will be more compact, efficient and intelligent. Miniaturized UV power supply will be more portable and suitable for various scenes. Efficient UV power supply will reduce energy consumption and improve energy utilization. Intelligent UV power supply will have automatic adjustment function to achieve the best working state according to different load requirements.

< conclusion >
 UV power supply is a key electronic equipment, which is widely used in ultraviolet disinfection, ultraviolet curing, lithography and other fields. Its principle is to convert alternating current into direct current suitable for ultraviolet lamps, and its working modes can be divided into constant voltage and constant current. The constant voltage working mode of UV power supply is suitable for ultraviolet disinfection and lithography, and the constant current working mode is suitable for ultraviolet curing. In the future, UV power supply will be more compact, efficient and intelligent, providing better support for applications in various fields.
