峰值电流控制DC-DCBoost变换器优化斜坡补偿（英文） Title:PeakCurrentControlOptimizationofDC-DCBoostConverterwithSlopeCompensation Abstract: ThispaperpresentsacomprehensivestudyandoptimizationapproachforslopecompensationinpeakcurrentcontrolofDC-DCBoostconverters.Peakcurrentcontrolisawidelyusedtechniqueinpowerelectronicstoregulatetheoutputvoltageofpowerconverters.However,thistechniquemaysufferfromcontrolinstabilityandinaccuracy,particularlyathighswitchingfrequencies.Slopecompensationisatechniquethatcaneffectivelyovercomethesechallengesbycompensatingforthenon-idealcharacteristicsofthepowerinductor. Introduction: DC-DCBoostconvertersareextensivelyemployedinvariousapplications,suchasrenewableenergysystems,electricvehicles,andtelecommunications.Thekeyobjectiveindesigningpowerconvertersistoachieveefficientpowertransferwhilemaintainingastableoutputvoltage.Peakcurrentcontrolisacommonlyutilizedmethodtoregulatetheoutputvoltageandlimitinductorcurrentintheseconverters.However,controlinstabilityandaccuracydegradationoftenoccurduetothenon-idealcharacteristicsoftheinductor,suchasitsinternalresistanceandparasiticcapacitance. Methods: TooptimizetheperformanceofpeakcurrentcontrolinDC-DCBoostconverters,slopecompensationisintroduced.Slopecompensationisatechniquethatcompensatesforthenon-idealcharacteristicsoftheinductor,resultinginimprovedstabilityandaccuracy.Thepaperproposesasystematicapproachtooptimizeslopecompensationbyanalyzingthedynamicsoftheconverterandselectingappropriatecompensationparameters. Theoptimizationprocessinvolvesthefollowingsteps: 1.ModelingtheDC-DCBoostconverterandidentifyingthetransferfunctionthatrelatestheoutputvoltagetothedutycycleandload. 2.Analyzingthestabilityoftheconverter'scontrolloopandidentifyingpotentialinstabilityissues. 3.Introducingslopecompensationandderivingthecompensationparameterbasedontheinductor'sinternalresistanceandparasiticcapacitance. 4.Simulatingtheperformanceoftheconverterwithandwithoutslopecompensationtoevaluatetheeffectivenessofthecompensationtechnique. 5.Exper
