Dab tsi yog lub hnub ci charger?
Lub hnub ci tus nqi tswj (tseem hu ua lub hnub ci vaj huam sib luag voltage regulator) yog tus tswj xyuas cov txheej txheem them nqi thiab tawm hauv lub hnub ci zog.
Lub luag haujlwm tseem ceeb ntawm tus tswj hwm tus nqi yog tswj cov kev them nqi tam sim no los ntawm PV vaj huam sib luag mus rau lub roj teeb, ua kom cov dej ntws ntws los ntawm qhov siab dhau los tiv thaiv lub txhab nyiaj roj teeb kom tsis txhob overcharge.
Ob hom ntawm lub hnub ci nqi tswj
MPPT & PWM
MPPT thiab PWM yog cov kev tswj fais fab uas siv los ntawm cov tswj hwm los tswj cov dej ntws ntawm lub hnub ci mus rau lub roj teeb.
Thaum PWM chargers feem ntau yuav tsum tau pheej yig thiab muaj 75% kev hloov pauv tus nqi, MPPT chargers yog me ntsis kim dua los yuav, MPPT qhov tseeb tuaj yeem nce qhov hloov pauv ntau txog 99%.
Lub PWM maub los yog qhov tseem ceeb hloov pauv uas txuas lub hnub ci array rau lub roj teeb.Qhov tshwm sim yog tias qhov voltage ntawm lub array yuav raug rub los ze rau qhov voltage ntawm lub roj teeb.
Lub MPPT maub los yog qhov nyuaj dua (thiab kim dua): nws yuav kho nws qhov hluav taws xob tawm tswv yim kom siv lub zog siab tshaj plaws los ntawm lub hnub ci array, thiab tom qab ntawd txhais lub zog ntawd mus rau qhov sib txawv ntawm qhov yuav tsum tau muaj rau lub roj teeb thiab lub nra.Yog li, nws yog qhov tseem ceeb decouples qhov voltages ntawm cov array thiab cov roj teeb, yog li ntawd, piv txwv li, muaj 12V roj teeb ntawm ib sab ntawm MPPT tus nqi tswj thiab cov vaj huam sib luag txuas rau hauv series los tsim 36V ntawm sab nraud.
Qhov sib txawv ntawm MPPT & PWM hnub ci nqi tswj hauv daim ntawv thov
PWM controllers feem ntau yog siv rau cov tshuab me me nrog cov haujlwm yooj yim thiab lub zog qis.
MPPT controllers yog siv rau me me, nruab nrab, thiab loj PV systems, thiab MPPT controllers yog siv rau nruab nrab thiab loj systems uas muaj ntau yam yuav tsum tau, xws li fais fab mov.
Tshwj xeeb MPPT controllers yog siv nyob rau hauv me me off-grid systems, caravans, nkoj, txoj kev teeb, hluav taws xob qhov muag, hybrid systems, thiab lwm yam.
Ob lub PWM thiab MPPT controllers tuaj yeem siv rau 12V 24V 48V systems, tab sis thaum lub zog wattage siab dua, MPPT maub los yog qhov kev xaiv zoo dua.
MPPT maub los kuj txhawb cov tshuab hluav taws xob loj loj nrog cov hnub ci vaj huam sib luag hauv cov koob, yog li ua kom siv cov hnub ci vaj huam sib luag.
The Charge Difference of MPPT & PWM Solar Charger Controller
Pulse width modulation technology tsub lub roj teeb nyob rau hauv 3-theem them nqi ruaj khov (bulk, ntab, thiab nqus).
MPPT thev naus laus zis yog qhov ntsuas siab tshaj plaws thiab tuaj yeem suav hais tias them nyiaj ntau theem.
Lub zog hloov dua siab tshiab ntawm MPPT lub tshuab hluav taws xob yog 30% siab dua piv rau PWM.
PMW suav nrog 3 theem ntawm kev them nyiaj:
Batch them;Absorption them;Float charging
Qhov twg ntab them yog qhov kawg ntawm 3 theem ntawm kev them nyiaj, tseem hu ua trickle charging, thiab yog daim ntawv thov ntawm tus nqi me me rau lub roj teeb ntawm tus nqi qis thiab tsis tu ncua.
Feem ntau cov roj teeb rechargeable poob lub zog tom qab lawv them tag nrho.Qhov no yog tshwm sim los ntawm tus kheej tso tawm.Yog tias tus nqi khaws cia ntawm qhov qis tam sim no raws li qhov ntsuas tus kheej tawm, tus nqi tuaj yeem khaws cia.
MPPT kuj muaj 3-theem them cov txheej txheem, thiab tsis zoo li PWM, MPPT muaj peev xwm hloov pauv them raws li PV cov xwm txheej.
Tsis zoo li PWM, lub sijhawm them nyiaj ntau muaj qhov them nyiaj ruaj khov.
Thaum lub hnub ci muaj zog, qhov tso zis hluav taws xob ntawm PV cell nce ntau heev thiab cov nqi them tam sim no (Voc) tuaj yeem ncav cuag qhov pib sai.Tom qab ntawd, nws yuav tso tseg MPPT them thiab hloov mus rau txoj kev them nyiaj tam sim no.
Thaum lub hnub ci tsis muaj zog thiab nws tsis yooj yim los tswj kev them nyiaj tam sim no, nws yuav hloov mus rau MPPT them.thiab hloov dawb kom txog rau thaum qhov hluav taws xob ntawm lub roj teeb sab nce mus rau qhov saturation voltage Ur thiab lub roj teeb hloov mus rau qhov hluav taws xob tas li.
Los ntawm kev sib txuas MPPT them nrog kev them nyiaj tas li tam sim no thiab hloov pauv tsis siv neeg, hnub ci zog tuaj yeem siv tau tag nrho.
Xaus
Hauv cov ntsiab lus, kuv xav tias MPPT kom zoo dua, tab sis PWM chargers kuj xav tau los ntawm qee tus neeg.
Raws li qhov koj tuaj yeem pom: ntawm no yog kuv qhov xaus:
MPPT tus nqi tswj yog qhov zoo tshaj plaws rau cov tswv lag luam tab tom nrhiav tus tswj uas tuaj yeem ua cov haujlwm xav tau (lub zog hauv tsev, RV fais fab, nkoj, thiab kab hluav taws xob txuas hluav taws xob).
PWM tus nqi tswj tau zoo tshaj plaws rau cov ntawv thov hluav taws xob me me uas tsis tas yuav muaj lwm yam nta thiab muaj peev nyiaj ntau dua.
Yog tias koj tsuas yog xav tau tus maub los yooj yim thiab pheej yig rau cov teeb pom kev zoo me me, ces PWM controllers yog rau koj.
