电子设计大赛实验报告

1/162014年江苏省大学生电子设计竞赛实验报告无线电能传输装置（F题）2014年8月15日摘要：本设计基于磁耦合式谐振荡电路来进行无线电能传输，点亮LED灯。由于输入和输出都是直流电的形式，因此本系统将分为以下四个部分：第一部分为驱动电路（DC-AC），为使直流分量转化成交流电并通过耦合线圈将电能传输给负载，采用LC谐振的方式让回路中电容和电感构成一个二阶LC谐振电路，驱动MOS管形成交流电。第二部分为发射电路（AC-AC），应用电磁感应原理，在二次线圈中产生感应电流并输给接受电路。第三部分为电能转换电路（AC-DC），输出的感应交流电经整流桥桥式整流后流入升压电路。第四部分为升压电路（DC-DC），对整流之后的直流进行升压，防止整流后的电压无法驱动LED。本设计分模块搭建并对各个部分电路进行原理分析。在调试时，采用分模块调试，根据调试结果修改参数，最终形成一个完整的稳定系统。关键词：磁耦合式谐振荡电路LC振荡电路桥式整流DC-DC升压[Abstract]Thedesignisbasedonmagneticresonanceoscillationcircuitcoupledtothewirelesspowertransmission,litLEDlights.Sincetheinputandoutputareintheformofdirectcurrent,sothesystemwillbedividedintothefollowingfourparts:Thefirstpartofthedrivecircuit(DC-AC),isconvertedintoalternatingcurrentsothattheDCcomponentandthepowertransmissionthroughthecouplingcoiltotheload,usingLCresonantcircuitinamannersothatthecapacitanceandinductanceformasecondorderLCresonantcircuit,theACdriveMOStubeformation.Thesecondpartisthetransmittercircuit(AC-AC),applicationoftheprincipleofelectromagneticinduction,2/16inducedcurrentinthesecondarycoilandlosttoacceptcircuit.Thethirdpartisthepowerconvertercircuit(AC-DC),alternatingcurrentoutputinducedbytheflowintotheboostercircuitbridgerectifierbridgerectifier.Thefourthpartistheboostcircuit(DC-DC),DCrectifiedafterboostingpreventrectifiedvoltagecannotdriveLED.Thedesignofthevariouspartsofsub-modulestructuresandprinciplesofcircuitanalysis.Whendebugging,usingsub-modulesdebug,modifyparametersbaseddebuggingresults,eventuallyformingacompletestabilizationsystem.[Keywords]MagneticallycoupledharmonicoscillatorcircuitLCoscillatorcircuitbridgerectifierDC-DCboost目录EquationChapter1Section12014年江苏省大学生电子设计竞赛实验报告.................................................1无线电能传输装置（F题）.............................................................................................................................1摘要：本设计基于............................................................................................................................................1关键词：................................................................................................................................................................1磁耦合式谐振荡电路LC振荡电路桥式整流DC-DC升压........................................................................11系统方案.............................................................................................................................................................31.1发射驱动电路方案的论证及分析..............................................................................................................41.2接收电路方案的论证及分析：..................................................................................................................41.3输出电路方案的论证和选择：..................................................................................................................42系统理论分析与计算.........................................................................................................................................52.1电路设计分析及原理..................................................................................................................................52.1.1发射驱动电路的设计分析...................................................................................................................62.1.2接收电路的分析...................................................................................................................................72.1.3输出电路的分析..................................................................................................................................92.2发射驱动回路器件的选择及参数计算..................................................................................................102.3接收电路回路器件的选择及参数计算...................................................................................................102.4发射与接收线圈的选择及参数计算......................................................................................................103电路与程序设计..............................................................................................................................................113.1电路的设计...............................................................................................................................................113/163.1.1系统总体框图....................................................................................................................................113.1.2发射驱动电路字系统框图与电路原理图........................................................................................113.1.3接收电路系统框图与电路原理图....................................................................................................123.1.4发射电路原理....................................................................................................................................124测试方案与测试结果......................................................................................................................................134.1测试方案...............................................................................................................................................
