Inverter, tseem hu ua lub hwj chim regulator, lub hwj chim regulator, yog ib qho tseem ceeb ib feem ntawm lub photovoltaic system.Qhov tseem ceeb tshaj plaws txoj hauj lwm ntawm lub photovoltaic inverter yog los hloov DC lub zog uas tsim los ntawm lub hnub ci vaj huam sib luag rau hauv AC zog siv los ntawm cov khoom siv hauv tsev.Tag nrho cov hluav taws xob tsim los ntawm lub hnub ci vaj huam sib luag tuaj yeem raug xa tawm los ntawm kev kho mob ntawm inverter.through-bridge Circuit Court, feem ntau siv SPWM processor los ntawm kev hloov kho, lim dej, kev txhawb nqa hluav taws xob, thiab lwm yam, kom tau txais qhov sinusoidal AC system txuam nrog lub teeb pom kev zoo. load zaus, ntsuas voltage rau cov neeg siv kawg.Nrog lub inverter, DC roj teeb tuaj yeem siv los muab AC fais fab rau cov khoom siv.
Hnub ci AC lub zog tsim hluav taws xob muaj cov hnub ci vaj huam sib luag, them nyiaj tswj, inverter thiab roj teeb;Hnub ci DC lub zog tsim hluav taws xob tsis suav nrog inverter.Cov txheej txheem ntawm hloov AC lub zog hluav taws xob rau hauv DC lub zog hluav taws xob yog hu ua rectification, Circuit Court ua kom tiav cov kev ua haujlwm rectification yog hu ua rectifier circuit, thiab cov cuab yeej uas paub txog cov txheej txheem rectification yog hu ua lub rectifier ntaus ntawv los yog lub rectifier.Correspondingly, cov txheej txheem ntawm converting DC lub zog hluav taws xob mus rau hauv lub AC hluav taws xob lub zog yog hu ua lub inverter, lub Circuit Court ua kom tiav lub inverter muaj nuj nqi hu ua lub inverter Circuit Court, thiab cov cuab yeej uas paub txog cov txheej txheem inverter. yog hu ua cov khoom siv inverter lossis lub inverter.
Lub hauv paus ntawm lub inverter ntaus ntawv yog lub inverter hloov Circuit Court, tsuas yog lub inverter Circuit Court.Lub Circuit Court ua kom tiav lub inverter muaj nuj nqi los ntawm lub on thiab tawm ntawm lub hwj chim hluav taws xob hloov.On-off ntawm lub hwj chim hluav taws xob switching li yuav tsum tau tej yam tsav tsheb pulses, uas tej zaum yuav. tswj los ntawm kev hloov lub teeb liab voltage.Cov circuits uas tsim thiab tswj pulses feem ntau hu ua ib tug tswj Circuit Court los yog ib tug tswj Circuit Court.Qhov yooj yim qauv ntawm lub inverter ntaus ntawv, ntxiv rau cov saum toj no-hais inverter Circuit Court thiab tswj Circuit Court, kuj muaj ib tug tiv thaiv Circuit Court, output circuit, output circuit, output circuit thiab lwm yam.
Centralized inverter feem ntau yog siv rau hauv cov tshuab nrog cov chaw nres tsheb loj photovoltaic (> 10kW).Ntau qhov sib npaug photovoltaic pawg txuas nrog DC cov tswv yim ntawm tib lub hauv nruab nrab inverter.Feem ntau, lub zog loj siv peb-theem IGBT fais fab module, lub zog me me siv cov nyhuv transistors, thiab siv DSP hloov dua siab tshiab maub los los txhim kho qhov zoo ntawm cov hluav taws xob tso zis hluav taws xob, ua rau nws ze heev rau qhov sinusoidal yoj tam sim no.Qhov loj tshaj feature yog qhov siab. lub zog thiab tus nqi qis.Txawm li cas los xij, vim yog qhov sib txuam ntawm cov pab pawg photovoltaic series thiab ib nrab shading, nws ua rau kev ua haujlwm thiab lub zog muaj peev xwm ntawm tag nrho cov photovoltaic system.Tam sim no, lub zog tsim kev ntseeg siab ntawm tag nrho cov photovoltaic system yog cuam tshuam los ntawm kev ua haujlwm tsis zoo ntawm ib pawg photovoltaic unit.Qhov kev tshawb fawb tshiab tshaj plaws yog kev tswj hwm ntawm spatial vectors, nrog rau kev txhim kho cov kev sib txuas topological ntawm cov inverter tshiab kom tau txais kev ua haujlwm siab hauv ib nrab ntawm cov teeb meem.On SolarMax ( SowMac) centralized inverter, lub thawv photovoltaic array interface tuaj yeem muab ntxiv los saib xyuas txhua series ntawm photovoltaic vaj huam sib luag series.Yog tias cov txheej txheem ntawm lawv tsis ua haujlwm zoo, lub kaw lus yuav xa cov ntaub ntawv mus rau cov chaw taws teeb tswj, thiab nws tuaj yeem nres cov koob los ntawm cov chaw taws teeb tswj, kom tsis txhob ua rau tsis ua haujlwm txo thiab cuam tshuam rau kev ua haujlwm thiab lub zog tawm ntawm tag nrho. photovoltaic system.
