基于SG3525的新型二氧化碳激光器电源设计

摘要

Now,the carbon dioxide laser is widely used in the fields of laser cutting,welding, surface treatment, drilling and micro -processing. It is very important for laser processing and performance to keep stable source pump up and steady optical power output.This paper presents a design of new laser power based on the power management IC SG3525 .The test results show that the laser power has good reliability and stability,and it also has good applications prospects in the market.%目前二氧化碳激光器在激光切割、焊接、表面处理、打孔及微加工等领域应用十分广泛。稳定的泵补源以及稳定的光功率输出对于激光加工的成败及优良性起着至关重要的作用。提出了一款基于开关电源管理芯片SG3525的新型二氧化碳激光器电源设计方案，从样机实际效果来看该激光电源具有较好的可靠性和稳定性，具有较好的市场应用前景。
