In this paper,the design scheme of switching pulsed laser power supply system is discussed,and the realization of its function is verified by MTALAB simulation.According to the characteristics of pulsed xenon lamp and the working principle of pulsed laser power supply,the main circuit of power conver-sion based on series resonant half-bridge converter is designed to ensure low voltage noise and good stability of power supply.At the same time,high-frequency high-voltage transformers are used to reduce electromag-netic interference and improve conversion efficiency.After the completion of the system design,the MATLAB simulation software is used to build the system model and verify its function.The results show that the soft start function,self-protection function and slow power-on function of the system can be realized normally and meet the design expectation.
