电视机电源电路的分析与仿真摘要：进入21世纪以来,利用计算机仿真辅助设计开关电源已成为国际电源领域的一项新技术。利用这些计算机仿真软件不仅能完成开关电源的优化设计，还能对开关电源进行仿真,彻底改变了依赖于人工计算、样机制作和调试的传统设计模式，降低开发研制的成本、缩短了设计周期。本文论述了普通电源电路的分析与仿真以及具体电视机电源的分析与仿真并简要介绍了PSPICE的功能。给出了电视机开关电源电路实例，详细论述了日立CTP-236D电视机电源工作原理，对日立CTP-236D电视机电源电路进行了仿真。本文采用通用电路分析软件PSPICE，在保证模拟电路精度的情况下，建立实时电路仿真模型，进而对电视机开关电源系统进行计算机实时仿真分析，该方法可优化系统的设计方案，验证实际电视机电源的工作特性。关键字：电视机；开关电源；PSPICE仿真TVPowerSupplyCircuitAnalysisandSimulationAbstract:Enteringthe21stcentury,usingcomputerdesignofswitchpowersupplyareashasbecometheinternationalnewtechnology.Usingthesoftwarenotonlycanfinishtheoptimizationdesignofswitchpowersupply,alsocanswitchpowersimulation,thoroughlychangedthedependentonartificialcalculation,theprototypemanufacturingandtestingoftraditionaldesignpatterns,reducethecost,shortenthedevelopmentcycleofdesign.ThispaperdiscussesthegeneralpowercircuitanalysisandsimulationandanalysisandsimulationoftheTVset,andbrieflyintroducesPSPICEfunction.GiventheTVswitchingpowersupplycircuitexamples,expounds236D-HitachiCTPpower,workingprincipleofTVsets236D-HitachiCTPofpowerissimulated.Basedoncommoncircuitanalysissoftware,PSPICEsimulatingcircuits,theestablishmentoftheaccuracyofreal-timesimulationmodel,thentheTVswitchingpowersupplysystembycomputersimulationanalysis,thismethodcanbeoptimizeddesignschemeofthesystem,theactualworkingcharacteristicsofTVset.Keywords:sets；switchpowersupply；PSPICEsimulation目录1引言...............................................................................................................12电源电路综述.................................................................................................12.1电源电路组成及电路作用...............................................................................12.1.1电源电路的整流电路..............................................................................................22.1.2电源电路的滤波电路..............................................................................................22.1.3电源电路的稳压电路..............................................................................................22.1.4电源电路的保护电路..............................................................................................32.2电源电路各部分的分析与仿真.......................................................................32.2.1整流电路的分析与仿真.........................................................................................32.2.2电容滤波电路的分析与仿真...............................................................................42.2.3电感滤波电路的分析与仿真...............................................................................62.2.4稳压电路的分析与仿真.........................................................................................73开关电源电路.................................................................................................93.1开关电源简介...................................................................................................93.2并联型开关稳压电源组成.................
