Txheej txheem cej luam ntawm hnub ci ntsa iab photovoltaic
Lub hnub ci maub los yog ib qho tseem ceeb ntawm lub hnub ci fais fab, ib qho khoom siv hluav taws xob uas tuaj yeem tiv thaiv kom txhob muaj roj teeb ntim ntawm overcharged thiab overdischarged thiab muaj kev ntsuas yooj yooj yim. Txij li thaum lub roj teeb pob ntau dua thiab yuav ua rau nws qhov ua tau zoo thiab lub neej, qhov kev tswj thiab paug tswj yog feem ntau yog qhov tseem ceeb hauv cov tshuab photovoltaic. Nws feem ntau txiav txim siab qhov kev ntseeg ntawm hnub ci lub tshuab photovoltaic. Cov cim ntawm tus maub los yog tsuas yog los paub lub txim ntawm lub roj teeb los ntawm lub hnub ci zog thiab tiv thaiv lub roj teeb hauv lub tshuab fais fab.
Ntsiab cai ntawm cov hnub ci ntsa iab photovoltaic
Ib qho thaum uas tig mus ntaus nqi thiab pauv plawg:
Qhov hloov twj ntaus nqi T1 hauv tus nqi hluavtaws xob ntawm cov khoom siv sib luag thiab cov paug qis yog txuas nrog rau qhov tso zis xaus rau ntawm lub hnub ci ntsa iab. Thaum lub roj teeb voltage siab tshaj qhov "puv puv ntuag", qhov hloov twj ntaus T1 yog hluavtaws ua hluav taws xob thiab tsim tau tib lub sijhawm. A1 yog ib qho kev tshaj tawm tswj xyuas kev tswj hwm overvoltage. Lub ntsiab lus ntawm lub dav hlau ntawm A1 uas tsis raug xa tawm tau muab nrog qhov reference voltage sib thooj rau "overhead cutoff" los ntawm W1, thiab lub thawv qhov xa rov qab txuas nrog lub roj teeb sab. Thaum lub roj teeb voltage siab tshaj "kev siv hluav taws xob ntau tshaj", A1 cov zis tshav dav hlau G1 yuav tsis tshua muaj theem, cov twj T1 switching yog muab tua, tus nqi hluav taws xob yog txiav tawm, thiab kev tiv thaiv overvoltage yog siv. Thaum lub roj teeb voltage tee rau tsawg dua ntawm "kev siv lub zog rov tuaj" ntawm kev tiv thaiv overvoltage, cov tswv yim inverting ntawm A1 Thaum cov neeg muaj peev xwm tsawg tshaj li qhov tsis muaj kev tawm tswv yim, qhov tawm ntawm lub G1 hloov ntawm theem qis rau qib siab , thiab cov cuab yeej hloov T1 yog muab tua los ntawm kev xa tawm, thiab lub Circuit Court charging yog muab dua. Qhov "cutoff threshold overvoltage" thiab "overrevage recovery threshold" yog kho los ntawm W1 thiab R1.
A2 yog ib qho kev sib xyuas tswj kom tsis muaj kev sib tw uas nws qhov kev sib tshuam uas txuas mus txuas rau lub thev xaav ntawm W2, thiab lub tshav dav hlau uas tsis txuas rov qab yog txuas nrog lub roj teeb hluav taws xob (as opposed to Circuit Supervoltage Detection Control Circuit). Thaum lub roj teeb voltage tsawg tshaj li "qhov tsis muaj theem pib" Cov zis lub davhlau G2 ntawm A2 tsis tshua muaj theem, thiab cov twj T2 switching yog muab tua, thiab cov kauj voj khiav tawm ntawm tus maub los txiav tawm kom paub "kev tiv thaiv qis". Tom qab kev tiv thaiv tsis muaj teeb meem, raws li cov roj teeb hluav taws xob nce ntxiv, thaum lub qhov hluav taws xob siab tshaj qhov "rov ua tsis tau zoo dua", lub twj hloov T2 rov qab rau, thiab lub hwj huam mov rau lub nkoj rov pib dua. Qhov "kev tiv thaiv kev tiv thaiv qis" thiab "txo qis dua tus nqi" yog kho los ntawm W2 thiab R2.
Hnub ci PV xws li khoom nta
1. Lub photovoltaic controller txais cov kev hloov ntawm kev sib hloov ntawm cov neeg ua haujlwm, uas muaj kev hloov siab, kev hloov loj, me me thiab lub cev nyhav.
2. Lub photovoltaic maub tau txais kev kawm raws li hlau nanocrystalline sib nqus khoom uas muaj hlau nplaum permeability, tsawg poob thiab txuag hluav taws xob zoo.
3. Lub zog fais fab teb cov lus teb yog qhov zoo thiab qhov ripple me me.
4. Lub tswv yim tseem ceeb ntawm cov tswj fais fab PV yog tuaj thiab kuaj thiab cov laus, thiab cov txheej txheem tsim cov txheej txheem thiab kev soj ntsuam cov txheej txheem kom ntseeg tau tias muaj kev ntseeg siab.
5. Optimized circuit design tsim cov khoom kom muaj rectification thiab tswj kev them nqi zog tib lub sij hawm, tsis muaj cov khoom xyuas ntxiv.
6, nrog overvoltage, overcurrent, luv luv Circuit Court, anti-rov qab txuas, kub nyiaj them.
7, vaj huam sib luag ntawm qhov hluav taws xob, tam sim no muaj nuj nqi digital. Muaj nyob rau hauv hauv lub hauv screen los yog portable daim ntawv ceeb toom.
8, raws li tus neeg yuav tsum tau ua kom zoo tshaj plaws tsim kho cov khoom siv, muab kev daws teeb meem, tsim prototypes, thiab sim tsim cov khoom zoo rau cov neeg siv khoom.
