Lub npe tag nrho ntawmmicro-inverteryog micro solar grid-tied inverter.Nws yog tsuas yog siv nyob rau hauv lub tshuab hluav taws xob photovoltaic thiab feem ntau yog hais txog inverters thiab module-theem MPPTs nrog lub zog ntsuas tsawg dua 1500W.Micro-invertersyog qhov me me piv rau cov pa hauv nruab nrab inverters.Micro-invertersinvert txhua module ib tus zuj zus.Qhov zoo dua yog tias txhua qhov module tuaj yeem tswj hwm nws tus kheej los ntawm MPPT.Qhov no zoo heev txhim kho lub zuag qhia tag nrho efficiency.Tib lub sijhawm,micro-inverterstuaj yeem zam qhov teeb meem ntawm qhov siab DC voltage, tsis zoo lub teeb pom kev zoo, thiab cov txiaj ntsig ntawm lub hauv paus inverters.
Micro-inverterstswj cov kev sau ntawm lub hnub ci zog ntawm ib tug neeg vaj huam sib luag los ua kom cov efficiency ntawm lub hnub ci installation, es tsis ua hauj lwm nyob rau hauv tag nrho cov system raws li ib tug central inverter yuav.Yav dhau los, cov txheej txheem tswj kev nyuaj siv los xyuas kom meej qhov ua tau zoo tshaj plaws thaum sau hnub ci tau nce cov nqi thiab txwv qhov kev siv ntawm micro-inverters.Integrated Circuit Court thiab processor-raws li kev daws teeb meem yog ob qho tib si sophisticated thiab nqi-zoo los tswj cov logic tswj ntawmmicro-invertertsim.Ntau yam voltage controllers thiab regulators kuj muab cov kev daws teeb meem ntxiv rau kev tsim hluav taws xob los ntawm DC tso zis ntawm hnub ci vaj huam sib luag.
Hauv qhov yooj yimmicro-invertertsim, interleaved active clamped flyback inverter txhim kho qhov tsawg voltage DC voltage los ntawm lub hnub ci vaj huam sib luag thiab high voltage AC waveform xav tau los ntawm daim phiaj.
Zoo li kev tsim khoom siv hluav taws xob,micro-invertertsim kom muaj ntau yam txuj ci los txhim kho kev ua tau zoo thiab kev ntseeg tau.Ib qho interleaved flyback topology yog siv, uas yuav pab txo cov rms ripple tam sim no los ntawm lawv, yog li ncua lub neej ntawm electrolytic capacitors nyob rau hauv cov qauv no.Tsis tas li ntawd, kev siv cov txheej txheem clamping nquag tso cai rau lub voj voog ua haujlwm siab tshaj plaws, ua kom muaj kev siv ntau dua lem.Qhov no tuaj yeem txo qhov kev thauj khoom tam sim no ntawm thawj sab thiab qhov hluav taws xob hluav taws xob nyob rau sab thib ob.
Txhawm rau kom ntseeg tau tias lub zog siab tshaj plaws, lub inverter yuav tsum muaj peev xwm teb taumicro-invertertswj logic.Cov logic no yog tsim los ua kom qhov voltage thiab tam sim no ntawm lub converter kom ze li sai tau rau cov yam ntxwv xav tau tsim los ntawm MPPT algorithm.Qhov tseem ceeb tshaj, kab sib chaws-txuasmicro-invertersyuav tsum muaj peev xwm txiav tawm ntawm kab hluav taws xob thaum muaj hluav taws xob tsis ua haujlwm.Cov kev tiv thaiv txhaum cai no, nyob rau hauv lem, yuav tsum tau lub inverter kom muaj tsawg kawg yog overvoltage thiab undervoltage nrhiav kom tau.
Tus tsim ntawmmicro-invertersimposes tswj, hwj chim hloov dua siab tshiab thiab efficiency yuav tsum tau txwv lawv cov kev siv dav hauv yav dhau los.Txawm li cas los xij, nrog kev loj hlob ntawm kev sib xyaw ua ke, cov neeg tsim qauv siv tau ntau yam khoom siv tsim nyog.Thaum cov txheej txheem siab tshaj plaws tuaj yeem muab cov kev tswj hwm qib siab thiab MPPT kev ua haujlwm xav tau raumicro-inverters, cov qauv tsim rau theem hloov hluav taws xob xav tau cov khoom siv uas tuaj yeem muaj kev nyab xeeb thiab muaj txiaj ntsig zoo xa cov kev ua haujlwm thiab kev ua haujlwm uas yuav tsum tau ua rau daim phiaj.Nrog rau ntau yam kev hloov pauv kev tswj hwm thiab PMICs muaj, cov kws tshaj lij tuaj yeem tsim kom muaj txiaj ntsig zoo, raug nqi hluav taws xob hloov pauv theem hauv micro-inverter tsim.
