Ntawm tam sim no, Tuam Tshoj lub photricsoltaic lub zog tiam yog feem ntau yog DC lub zog tsim los ntawm lub roj teeb hluav taws xob, thiab lub roj teeb ncaj ncees rau cov khoom siv. Piv txwv li, lub hnub ci hauv tsev teeb pom kev zoo hauv Suav teb thiab microwave chaw nres tsheb hluav taws xob kom deb ntawm daim phiaj yog txhua lub DC system. Hom txheej txheem no muaj cov qauv yooj yim thiab tus nqi qis. Txawm li cas los xij, vim muaj cov qauv sib txawv DC voltent (xws li 12v, 248v, thiab lwm yam ntawm lub zog ntawm pej xeem, raws li feem ntau ntawm AC loads yog siv nrog DC lub zog. Nws yog qhov nyuaj rau lub photovoltaic fais fab mov kom muab hluav taws xob muab nkag mus rau hauv kev ua lag luam ua khoom lag luam. Tsis tas li ntawd, photovoltaic lub zog tiam yuav kawg yuav ua tiav cov kev ua haujlwm sib txuas, uas yuav tsum tau txais yuav tus qauv ua lag luam paub tab. Yav tom ntej, Ac photovoltaic lub zog tiam yuav dhau los ua lub ntsiab ntawm photovoltaic lub zog hluav taws xob.
Cov kev cai ntawm photovoltaic zog tiam rau inverter fais fab mov
Lub photovoltaic zog tiam siv hluav taws xob siv cov zis fais fab muaj plaub yam: roj teeb thiab Inverter yog qhov tseem ceeb. Photovoltaic muaj ntau dua yuav tsum muaj rau inverters:
1. Yuav tsum muaj kev ua haujlwm siab. Vim tias cov nqi siab ntawm cov hlwb ci ntsa iab tam sim no, txhawm rau ua kom ntau tshaj plaws kev siv cov hlwb solar thiab txhim kho kev ua haujlwm zoo, nws yog qhov tsim nyog los sim txhim kho kev ua haujlwm ntawm inverter.
2. Kev ntseeg siab siab yuav tsum muaj. Ntawm tam sim no, photovoltaic lub zog tiam yog tsuas yog siv rau hauv thaj chaw deb, thiab ntau lub zog hluav taws xob tsis muaj kev saib xyuas thiab tswj hwm. Qhov no yuav tsum muaj lub inverter kom xaiv cov kev tiv thaiv hluav taws xob tsim nyog, thiab xav tau cov inverter luv luv kev tiv thaiv, overheating, overheing tiv thaiv, thiab lwm yam.
3. Lub DC cov tswv yim voltage yog yuav tsum muaj ntau ntau ntawm kev yoog. Txij li thaum lub davhlau povthawj hluav taws xob ntawm lub roj teeb hloov pauv nrog lub nra thiab lub roj teeb hluav taws xob hloov pauv nrog kev hloov ntawm lub peev roj uas seem thiab sab hauv kev tiv thaiv. Tshwj xeeb tshaj yog thaum lub roj teeb yog kev laus, nws lub davhlau ya nyob voltage nws txawv. Piv txwv li, lub davhlau ya nyob voltage ntawm 12 V roj teeb tuaj yeem sib txawv ntawm 10 V. Qhov no yuav tsum muaj cov inverter kom ua haujlwm hauv lub ntsuas hluav taws xob ntau.
4. Hauv nruab nrab thiab muaj peev xwm muaj peev xwm photovoltaic lub zog tiam, cov zis ntawm cov hluav taws xob inverter yuav tsum yog sine yoj nrog tsawg distortion. Qhov no yog vim hais tias hauv nruab nrab thiab loj-peev txheej, yog tias siv hluav taws xob square yog siv, cov zis yuav muaj ntau hom har hardonic, thiab ntau dua kev sib haum yuav tsim kom muaj kev sib haum xeeb ntxiv. Ntau cov photuavoltaic lub zog tiam tau thauj khoom nrog kev sib txuas lus lossis cov cuab yeej cuab tam. Cov khoom siv muaj cov kev yuav tsum muaj siab dua ntawm qhov zoo ntawm cov phiaj xwm fais fab. Thaum nruab nrab thiab muaj peev xwm loj photovoltaic lub zog tiam tau txuas nrog cov kab sib chaws nrog cov pej xeem muaj zog, lub inverter kuj yuav tsum tau tso tawm sine yoj tam sim no.
Inverter hloov siab dua tshiab tam sim no mus rau lwm qhov tam sim no. Yog hais tias ncaj qha cov hluav taws xob ncaj qha yog tsawg, nws yog boosted los ntawm kev hloov pauv tam sim no kom tau txais lwm txoj kev sib txawv ntawm cov hluav taws xob tam sim no thiab ntau zaus. Rau cov inverers loj-muaj peev xwm loj, vim muaj lub siab loj rau hluav taws xob, cov AC tso zis feem ntau tsis tas yuav muaj lub transformer los txhawb cov voltage rau 220V. Hauv nruab nrab thiab cov interverage me me, lub DC voltage yog qhov tsawg, xws li 12v, rau 24V, rau 24V, kev txhawb nqa Circuit Court yuav tsum yog tsim. Nruab nrab thiab cov tsis muaj peev xwm inverters feem ntau suav nrog Push-rub inverter ncig, Puv-Choj inverter Circuits thiab cov high-zaus betverter inverter voj voog. Thawb-rub tawm cov voj voog txuas cov nruab nrab ntsaws ntawm lub zog hloov mus rau qhov chaw ua haujlwm zoo, nws tuaj yeem txwv lub zog ua haujlwm, nws tuaj yeem ua rau muaj kev cuam tshuam nrog lub zog tam sim no, yog li kev ntseeg tau qhov kev ntseeg tau ntawm Circuit Court. Qhov tsis zoo yog tias kev hloov pauv hluav taws xob yog tsawg thiab muaj peev xwm tsav cov khoom inductive yog neeg pluag.
Tus Puv-Choj inverter Circuit Court kov yeej kev ua tiav ntawm lub laub-rub Circuit Court. Lub zog trantor kho cov zis padse dav, thiab tus nqi zoo ntawm cov zis tau hloov pauv tau raws li. Vim tias Circuit Coach muaj lub voj ywj pheej, txawm tias rau kev thauj khoom hauv inductive, cov zis voltage wavetform yuav tsis muaj kev cuam tshuam. Qhov tsis zoo ntawm Circuit Court yog lub zog tauv taws ntawm lub sab sauv thiab sab hauv av tsis sib koom nrog hauv av, yog li ib lub zog tsav tsheb lossis cov fais fab sib cais yuav tsum tau siv. Tsis tas li ntawd, txhawm rau tiv thaiv cov conduction ntau zaus ntawm cov caj npab sab saud thiab rov qab tsim, thiab lub sijhawm tuag yuav tsum tau ua kom nyuaj dua.
Cov zis ntawm Push-rub Circuit Court thiab puv-choj Circuit Court yuav tsum ntxiv ib kauj ruam hloov pauv. Vim tias cov hloov pauv kauj ruam hluav taws xob yog qhov loj me, cov khoom siv hluav taws xob ntau, nrog rau kev ua tiav cov hluav taws xob hloov kho, nrog rau kev hloov kho lub zog zoo dua qub, nrog rau kev hloov kho lub zog loj dua qub. Cov theem hauv ntej txhawb nqa hluav taws xob ntawm qhov inverter hluav taws xob tau txais kev siv nias-rub cov qauv, tab sis cov haujlwm ua haujlwm tau saum 20kHz. Lub Boost Transformer Admever Adopts High-zaus magricastic cov khoom siv cov khoom siv, yog li nws yog me me thiab lub teeb hauv qhov hnyav. Tom qab cov zaus ua ke tau hloov dua tshiab, nws hloov pauv mus rau hauv cov hluav taws xob siab dua tam sim no los ntawm kev siv hluav taws xob siab tam sim no (thiab tom qab ntawd ntau dua inverted los ntawm lub zog zaus inverter Circuit Coup.
Nrog cov qauv Circuit Cer Circuit Court, lub zog ntawm Inverter tau txhim kho tau zoo heev, tsis muaj-thauj cov inverter nrog kev txo qis, thiab ua tau zoo dua qub. Qhov tsis zoo ntawm cov Circuit Court yog tias lub Circuit Court yog qhov nyuaj thiab kev ntseeg tau yog qis dua ob lub voj voog saum toj no.
Kev tswj Circuit Coupraccuit Co Center
Lub cig cig lub ntsiab ntawm cov inverers saum toj no tau xav tau kom paub los ntawm kev tswj hwm hluav taws xob. Feem ntau, muaj ob txoj kev tswj hwm: Square yoj thiab wave thiab weak. Lub Inverter Fais Fab Cov Khoom Siv Hluav Taws Xob nrog Square yoj cov lus tawm yog yooj yim, qis hauv kev ua haujlwm tsawg, tab sis loj hauv cov nyom. Cov. Sine yoj tawm cov khoom tawm yog qhov kev txhim kho ntawm lub inverters. Nrog rau kev txhim kho ntawm microelectronics technology, microprocessors nrog PWM kev ua haujlwm kuj tseem tuaj tawm. Yog li ntawd, cov thev naus laus zis thev naus laus zis rau sine yoj tawm tau matured.
1. Invererers nrog square wruture tawm tam sim no feem ntau siv cov mem tes ntawm cov mem tes-dav kev sib xyaw ua ke, xws li SG 3 525, TL 494 thiab lwm yam. Kev xyaum tau ua pov thawj tias kev siv SG3525 kev sib xyaw ua ke ua ke ua ke ua tiav cov khoom siv hluav taws xob muaj peev xwm ua tiav cov kev ua haujlwm siab thiab tus nqi siab. Vim tias SG3525 muaj peev xwm muaj peev xwm tsav tsheb ncaj qha rau kev siv hluav taws xob ncaj qha thiab muaj kev tiv thaiv sab hauv, yog li nws txoj kev tiv thaiv hluav taws xob yog yooj yim heev.
2. The Inverter Controlational Circuit Court nrog sine yoj cov zis tuaj yeem tswj hwm los ntawm lub tuam txhab kev lag luam, thiab tsim los ntawm Motorola tuam txhab. MP 16 thiab PI C 16 C 73 tsim los ntawm Mi-Cro Chip Company, thiab lwm yam-nti Computers, thiab tuaj yeem teeb tsa sab saud thiab sab saud. Thaum lub sijhawm tuag, siv Intel Tuam Txhab
Xaiv cov khoom siv fais fab hauv lub circuit Court ntawm cov inverter
Qhov kev xaiv ntawm lub zog tseem ceeb ntawm lubinverteryog ib qho tseem ceeb heev. Tam sim no, cov hluav taws xob siv hluav taws xob feem ntau suav nrog Darlington Hwjchim Tower Tawv (Mos-Fairs Nyom Clistors (Ofulated Gate Clistors (iGB). T) thiab tig-off thyristor (GTO), thiab lwm yam uas siv hluav taws xob me me, cov pob hluav taws xob tsawg dua ntawm ig-voltage thiab lub tshuab muaj peev xwm loj. Qhov no yog vim hais tias lub xeev tsis kam ua rau muaj kev kub siab ntxiv, thiab IG BT yog nyob rau hauv super-loj-peev txheej (saum toj 100 kva) cov tshuab, gtos feem ntau siv cov hluav taws xob.
