摘要
在采用锂电池储能供电的降压斩波电路恒流激光二极管驱动源系统的设计中,建立了电池组、激光二极管的集成电路个人仿真程序( PSPICE)器件模型和闭环控制系统模型,经过仿真计算,确定了输出滤波电感电容的参数和实现闭环稳定的比列积分微分调节 (PID)参数,并研究了在负载变化和输入变化的条件下系统的稳定性。研究表明,采用该技术方案能实现恒流源输出电流大于 100 A,输出电压 230 V,电流纹波小于 3%。
Abstract
In the design of a power supply powered by energy storage system with a battery pack to drive laser diodes with BUCK chopper circuit for constant current and step-downvoltage,Personal Simulation Program with Integrated Circuit Emphasis(PSPICE) models,which of components such as the battery pack, laser diodes in series, and of system with a closed loop are constructed. Parameters of output inductances and capacitors for filtering circuit are determined by simulations as well as the optimized parameters of the Process Identifier(PID) to realize stability of the closed loop. The stability of the power supply is studied by simulation under different conditions. The results indicate that a constant current power supply made by this technology could output more than 100 A current and 230 V voltage with less than 3% ripple.
