文档介绍：摘要 Y1867405 荧光灯作为一种节能光源,在当今世界能源形势日益紧张的情况下,已经越来越广泛的应用到照明系统的设计中。在电子镇流器设计阶段需要采用仿真平台对荧光灯及其电子整流器进行建模与仿真,论文通过荧光灯和电子整流器的建模仿真以简化电子镇流器的设计工作。论文在分析荧光灯及其电子镇流器工作原理的基础上,详细讨论了T5荧光灯的电气特性,采用曲线拟合的方式建立了荧光灯电流有效值和等效电阻之间的数学模型,并仿真验证了荧光灯建模的正确性;分析了·款电子镇流器主控芯片 IR2155的内部结构,建立了内部振荡、死区时间控制、欠压检测、脉冲产生、高电平位移及脉冲滤波等模块的模型,并进行了电路仿真验证;最后将荧光灯与电子镇流器模型连接构成完整的系统,实现了荧光灯电子镇流器的建模仿真。关键词:荧光灯电子镇流器PSpice仿真建模 Abstract As anew energy-saving lighting source,fluorescent lamp ismore usedin the design oflightingsystems today whiletheenergy inthe world es increasingly andsimulation offluorescentlamp andelectronicballastisneeded in thedesign ofthe electronicballastissimplified by modeling andsimulating fluorescentlamp and electronicballast. Electricalcharacteristicsoffluorescentlamp ale discussesin detailbased on the analysis oftheworking principle offluorescentlamp,and a mathematical model between the current RMS andequivalent resistance offluorescentlamps iscreatedusing a curve fittingway which issimulated andverified internal structure of IR2 ofmodules suchasinternaloscillator,dead timecontrol,UVLO,pulse generate,high levelshiftand pulse filter ,the modeling andsimulation ofelectronicballastfor fluorescentlamp isachievedby connecting themodel offluorescentlamp andelectronic ballast as acomplete system.
