攀枝花学院本科毕业设计（论文）单周期控制及其在电力电子中的应用学生姓名：XXX学生学号：XXXXXXXXXXXX院（系）：电气信息工程学院年级专业：电气工程及其自动化指导教师：XXX教授二〇一三年六月攀枝花学院本科毕业设计（论文）摘要Ⅰ摘要20世纪90年代初期，在PWM控制技术基础上发展起来一种非线性大信号理论，即单周期控制技术，它是一种模拟的PWM控制技术。其实质是通过控制开关占空比，让每个开关周期内开关变量的平均值严格等于或正比于控制参考量。因其平均输入电流跟踪参考电流而且不受负载电流约束，故即便负载电流在谐波很大时也不会让输入电流畸变。就现有PWM控制法而言，单周期控制的特点有：简单结构、快速度响应、良好稳定性及高精度、高速度和高抗干扰等，这使其发展迅速且遍及各个领域,如:DC/DC变换、不间断电源、有源电力滤波器、光伏电源最大功率点跟踪控制、功率因数校正和功率放大等。本论文首先介绍了单周期控制技术的理论、研究现状和应用；分析了单周期控制的原理和单周期控制的控制机理；分析了单周期控制单相BoostPFC电路的基本原理；分析了单周期控制逆变电源在双极性和单极性两种工作模式下的工作原理；简单介绍了电力电子电路仿真的相关内容，并分别进行了对单周期控制单相BoostPFC电路和单周期控制逆变器下的双、单极性工作模式的MATLAB仿真验证。关键词单周期控制，单相BoostPFC，全桥逆变，MATLAB仿真攀枝花学院本科毕业设计（论文）ABSTRACTⅡABSTRACTInearly1990s,thePWMcontroltechnologydevelopedthetheoryofanonlinearsignal,onecyclecontroltechnologywhichisananalogPWMcontroltechnology.Itsessenceisbycontrollingtheswitchingdutycycle,sothattheaverageofeachswitchingcycleswitchvariableinputcurrenttotrackthereferencecurrentandisindependentoftheloadcurrentconstraints,soeveniftheloadcurrentislargeintheharmonicwillnotlettheinputcurrentdistortion.ThepurposeoftheexistingPWMcontrolmethod,thesimplestructureoftheonecyclecontrol,andrapidresponse,stabilityanditsdevelopmentofhigh-precision,highspeedandhighnoiseimmunityandcoveredawiderangeofareas,suchas:DC/DCconversion,uninterruptiblepowersupplies,activepowerfilter,photovoltaicmaximumpowerpointtrackingcontrol,powerfactorcorrectionandpoweramplifier.Thispaperintroducestheprinciple,researchstatusandapplicationofcontroltechnology.Principleofone-cyclecontrolandonecyclecontrolmechanismareanalyzed,andanalyzedthebasicprincipleofone-cyclecontrolofsingle-phaseBoostPFCcircuit.Onecyclecontrolimprovesinverterworkingprincipleandworkingprincipleoftwopairsofunipolarmode.Briefintroductionofthepowerelectroniccircuitsimulation,andthesingle-phasePFCcontrolcircuitandonecyclecontrolimprovecontrolinverterdualmonopoleoperationmodeoftheMATLABsimulation.KeywordsOneCycleControl，Single-phaseBoostPFC，Full-bridgeinverter，MATLABsimulation攀枝花学院本科毕业设计（论文）目录目录摘要.................................................................................................................................IABSTRACT..........................................................................................................................II1绪论...............................................................................................................................11.1单周期控制技术概述.................................................................................................11.2单周期控制技术的理论研究......................................................................................11.2.1单周期控制变换器可行性研究...........................................................................11.2.2单周期控制变换器的建模..................................................................................11.2.3单周期控制变换器的稳态和动态性能研究..........................................................11.3单周期控制技术在电力电子领域的应用.....................................................................22单周期控制技术...........................................................................................................42.1单周期控制的基本原理.............................................................................................42.2单周期控制的控制机理.............................................................................................62.3单周控制与PWM控制方法的比较...............................................................................93单周期控制在功率因数校正中的应用.....................................................................103.1单周期控制单相BOOSTPFC工作原理........................................................................103.2单周期控制单相BOOSTPFC控制回路设计.................................................................114单周期控制技术在全桥逆变器中的应用.................................................................144.1单周期控制单相全桥逆变器的原理..........................................................................144.2双极性控制模式......................................................................................................154.3双极性控制模式数字控制算法的实现......................................................................164.4单极性控制模式......................................................................................................175电力电子电路的仿真.................................................................................................205.1MATLAB/SIMULINK仿真平台.......................................................................................205.2示波器的使用和数据保存........................................................................................215.3SIMULINK模块库.......................................................................................................235.4单周期控制单相BOOSTPFC仿真...............................................................................255.5单周期控制器双极性控制模式的仿真......................................................................27攀枝花学院本科毕业设计（论文）目录5.6单周期控制器单极性控制模式的仿真......................................................................30结论.............................................................................................................
