“…Many researchers have explored the driving power of light sources. Xue Huiyun from Tianjin University has studied the driving of semiconductor lasers, using the synchronous buck chip TPS40304 and peripheral circuits to design [5] ; Chen Wanwan from Zhejiang University of Technology has studied the driving of combined deuterium-tungsten-halogen light sources, using the UC3843AN type BUCK chip as the main driver, with comparators and The design of the driver circuit was completed with a UC3843AN BUCK chip, together with a comparator and a Schmidt trigger [6] ; the National Institute of Standards and Technology of the United States conducted a study on the driving of LED light sources, and designed a V-I conversion circuit to drive LED light sources [7] . This project is designed to drive a tungsten halogen lamp.…”

In the field of radiation calibration of micro-optical loads, the stability of the light source is a technical problem that researchers must solve, the stability of the light source determines the accuracy of the radiation calibration results, at the same time, the stability of the light source is determined by the stability of the driving power supply, so based on the driving requirements of the radiation calibration light source, a tungsten halogen lamp driving power supply with an output current stability better than one thousandth of a percent is designed as a tungsten halogen lamp light source The thesis first analyses the advantages and disadvantages of switching power supplies and linear power supplies, and selects the linear power supply as the power supply structure according to the requirements, and analyses the working principle of the linear power supply, and then designs the corresponding circuit structure based on the working principle; finally, the experimental platform is built for power supply experiments, and after testing, the experimental results show that the output current stability of the power supply reaches After testing, the experimental results show that the output current stability of the power supply reaches three ten thousandths, and the stability of the light source reaches one ten thousandth when driving a 5W tungsten halogen lamp, which can meet the requirements of the tungsten halogen lamp driving power supply index.
