中文摘要在现代生活中，电力成为了人们不可分割的一部分，随着电力设备的不断发展，许多相应的问题都出现了。谐波污染和无功问题尤为严重。对此，许多国家都制定了相应的措施来解决这些问题，我国也对谐波污染出台了一系列标准，而我国对高功率因数单极性倍频电压型PWM整流器的研究起步较晚，对单极性倍频电压型PWM整流技术的工程应用研究还有待继续深入。因此，本文对单极性倍频电压型PWM整流器进行研究，对其进行单极性和双极性PWM调制分析，分析其工作原理，给出驱动、控制电路设计方案，并用仿真软件PLECS对理论分析进行验证。关键词电压型PWM整流器单极性倍频双极性毕业设计说明书（论文）外文摘要TitleResearchonUnipolarFrequencyDoubleVoltagePWMRectifierAbstractInmodernlife,electricityhasbecomeaninseparablepartofpeople.Withthecontinuousdevelopmentofpowerequipment,manycorrespondingproblemshaveappeared.Harmonicpollutionandreactivepowerproblemsareparticularlyserious.Inthisregard,manycountrieshaveformulatedcorrespondingmeasurestosolvetheseproblems.mycountryhasalsoissuedaseriesofstandardsforharmonicpollution.mycountry'sresearchonhighpowerfactorunipolarfrequencydoubledvoltagetypePWMrectifiersstartedlate.Theengineeringapplicationresearchofunipolarfrequencydoublingvoltage-typePWMrectificationtechnologystillneedstobefurtherdeepened.Therefore,thispaperstudiestheunipolarfrequency-doubledvoltage-typePWMrectifier,analyzesitsunipolarandbipolarPWMmodulation,analyzesitsworkingprinciple,givesadesignplanforthedriveandcontrolcircuit,andusesthesimulationsoftwarePLECStoanalyzethetheoryAnalyzetoverify.KeywordsVoltagetypePWMrectifierunipolarfrequencydoublerbipolar目录1绪论......................................................................................................................................11.1单相PWM整流器研究概况........................................................................................11.2单相PWM整流器的分类及其拓扑结构....................................................................11.3本课题的研究任务........................................................................................................42单相PWM整流器的原理及数学模型...............................................................................52.1单极性PWM调制........................................................................................................52.2双极性PWM调制........................................................................................................72.3单相PWM整流器的数学模型...................................................................................83单相PWM整流器的控制策略.........................................................................................113.1前馈型直接电流控制..................................................................................................113.2锁相环控制..................................................................................................................134主电路设计........................................................................................................................144.1交流侧电感设计..........................................................................................................144.2直流侧电容设计..........................................................................................................165仿真分析结果........................................................................................................
