摘　　要：半导体激光器作为一种高效率、高稳定性的光电器件,其驱动电源的性能直接影响半导体激光器输出特性以及使用寿命。为解决半导体激光器输出功率的稳定性以及鲁棒性等问题,研制一种具有高效率、低纹波、抗干扰能力强的半导体激光器驱动电源。首先,提出一种减小元器件电流应力的LCC谐振腔参数设计方法,通过数学模型建立配合实验分析,采用变频移相复合控制策略和线性自抗扰控制算法,提高了半导体激光器电源效率,减小了器件的电流应力和开关的导通损耗,同时具有较好的抗干扰能力,对于高性能半导体激光器的驱动电源系统的设计具有一定的指导意义。最后,仿真与实验的结果表明,该电源在输出电流0~40A范围内连续可调,电流纹波<0.8%,工作效率最高可达92%,具有稳定性高、纹波小、效率高、成本低以及鲁棒性较好等特点。The performance of their driving power will directly affect the output characteristics and service life of semiconductor lasers as a high-efficiency,high-stability optoelectronic device.A constant current drive power supply with high efficiency,low ripple,and excellent anti-interference ability was created for semiconductor lasers in order to address the issues with stability and robustness of the output power.To begin,this paper proposes a method for designing LCC resonant cavity parameters to reduce component current stress.The frequency conversion phase shifting compound control strategy and linear active disturbance rejection control algorithm are implemented using a mathematical model and experimental analysis.The power supply efficiency of the semiconductor laser is improved,the device′s current stress is reduced,the switch′s conduction loss is reduced,and it has better anti-interference ability,It has some implications for the design of high-performance semiconductor laser driving power supply systems.In the end,according to simulation and experiment results,the power supply may be constantly adjusted between an output current range of 0to 40A,with a current ripple of less than 0.8%and a working efficiency of up to 92%.The system combines durability,cost-effectiveness,high efficiency,low ripple,and exceptional stability.
