摘　　要：介绍了一种大功率激光二极管阵列驱动电源的设计方法。对电源的组成、工作原理和电流上升前沿影响因素进行了详细分析,对输出线结构和反馈电路进行优化,有效地解决了大电流、长距离传输条件下电流脉冲前沿缓慢的问题。测试结果验证了设计思路的可行性,驱动电源实现了0~300 A连续可调、稳定度优于0.3%的输出,在300 A,40 m输出时脉冲前沿24.7μs,为同类型的大功率激光二极管阵列驱动电源的工程化应用奠定了基础。A design method for a high-power laser diode array power supply is introduced. The structure, component and working principle of the proposed power supply are analyzed as well as the influencing factors on the output current pulse rise time. The structure of output cable and the sampling circuit are optimized. The output current pulse rise time is greatly shortened under the high-current and long-distance conditions. The testing results verify the feasiblity of the power design idea. The high-power laser diode array power supply features a continuous adjustable laser dirving current of 0-300 A,and the stability of output current achieves 0.3%. The output current pulse rise time is 24.7 μs given the current of 300 A and the output cable length of 40 m. It provides reference for the same type of designs and a basis for engineering applications.
