Study on energy management of high power LD driver power in laser

针对大功率LD泵浦固体激光器对驱动电源的要求,提出能量管理的概念,分别分析储能元件、开关元件、采样电阻、放电电阻在能量管理策略中的作用及降低损耗的方法,最后得出结论:降低电源内阻,降低电容压降,可以提高能量利用率,增加能量转化效率。经过具体实验结果分析,电源的能量转换效率可达到88%以上,验证能量管理策略的可行性。

For the requirements of high-power LD pumped solid-state lasers,the concept of energy management is put forward. The functions of energy storage components,switch components,sampling resistance,discharge resistance in the energy management and the methods for reducing the loss were analyzed in detail. When the resistance and capacitance drop in power source are reduced,this method can improve energy efficiency and increase the energy conversion efficiency. Through the analysis of the experimental results,the energy conversion efficiency of the power supply can be as high as 88 percent,which verifies the feasibility of energy management strategy.
