Yuav ua li cas lub Inverter hloov DC hluav taws xob los ntawm cov vaj huam sib luag hnub ci mus rau hauv AC rau koj lub tsev
Vim xav siv cov khoom siv hluav taws xob uas tsis ua rau ib puag ncig puas tsuaj, ntau tsev neeg tam sim no tig mus siv cov vaj huam sib luag hnub ci kom tau raws li lawv cov kev xav tau hluav taws xob. Ib qho tseem ceeb ntawm lub kaw lus no yog lub inverter. Lub inverter yog ib lub cuab yeej uas hloov cov hluav taws xob ncaj qha (DC) uas cov vaj huam sib luag hnub ci tsim tawm mus ua hluav taws xob hloov pauv (AC), uas cov khoom siv hluav taws xob hauv koj lub tsev siv tau. Tsab xov xwm no yuav tham txog qhov inverter ua haujlwm li cas thiab nws qhov tseem ceeb hauv lub kaw lus hluav taws xob hnub ci.
1. Vim li cas koj thiaj yuav tsum hloov DC mus rau AC?
Cov hluav taws xob muaj ob hom: hluav taws xob ncaj qha (DC) thiab hluav taws xob hloov pauv (AC). Cov khoom siv hluav taws xob hauv koj lub tsev, xws li TV, tub yees, thiab tshuab ntxhua khaub ncaws, feem ntau yog tsim los ua haujlwm ntawm hluav taws xob hloov pauv (AC). Cov vaj huam sib luag hnub ci, ntawm qhov tod tes, tsim hluav taws xob hauv daim ntawv ntawm hluav taws xob ncaj qha (DC). Yog li ntawd, txhawm rau koom ua ke lub zog los ntawm cov vaj huam sib luag hnub ci rau hauv koj lub tsev lub tshuab hluav taws xob, cov txheej txheem hloov pauv DC-rau-AC yog qhov tsim nyog, thiab qhov no yog qhov uas lub inverter ua lub luag haujlwm tseem ceeb.
2. Cov Vaj Huam Sib Luag Hnub Ci Ua Haujlwm Li Cas
Cov vaj huam sib luag hnub ci muaj ntau lub hlwb photovoltaic ua los ntawm cov khoom siv semiconductor xws li silicon. Thaum lub hnub ci ntsa iab rau cov hlwb photovoltaic, lub zog los ntawm cov photons hauv lub hnub ci ua rau cov electrons hauv cov khoom siv semiconductor zoo siab, tsim cov hluav taws xob ncaj qha (DC). Qhov no yog thawj kauj ruam hauv cov txheej txheem ntawm kev hloov lub zog hnub ci mus rau hauv lub zog hluav taws xob siv tau.
3. Kev Ua Haujlwm ntawm Inverter hauv Lub Hnub Ci Zog System
Lub inverter ua haujlwm ua tus neeg nruab nrab ntawm cov vaj huam sib luag hnub ci thiab koj lub tsev lub tshuab hluav taws xob. Nws lub luag haujlwm yog hloov cov hluav taws xob DC uas tsim los ntawm cov vaj huam sib luag hnub ci mus rau hauv hluav taws xob AC uas koj lub tsev cov khoom siv tuaj yeem siv. Cov txheej txheem no suav nrog ntau kauj ruam kev siv tshuab nyuaj kom ntseeg tau tias cov hluav taws xob tsim tau raws li cov qauv zoo thiab kev nyab xeeb.
4. Hom Inverters
Muaj ntau hom inverters siv rau hauv lub hnub ci zog, txhua tus muaj nws tus kheej qhov zoo thiab qhov tsis zoo:
a. Tus Qauv Inverter
Ib lub inverter txheem, lossis string inverter, txuas cov vaj huam sib luag hnub ci ua ib kab hu ua "string." Txhua lub vaj huam sib luag hauv cov hlua txuas nrog ib lub inverter. Yog tias ib lub vaj huam sib luag tsis ua haujlwm zoo, piv txwv li vim yog ntxoov ntxoo, tag nrho cov hlua yuav raug cuam tshuam, txo qhov kev ua haujlwm ntawm lub kaw lus tag nrho.
b. Micro Inverter
Cov microinverters raug muab tso rau ntawm txhua lub vaj huam sib luag hnub ci. Txhua lub vaj huam sib luag ua haujlwm ywj pheej, yog li ntawd yog tias ib lub vaj huam sib luag ua haujlwm tsis zoo vim yog ntxoov ntxoo lossis av qias neeg, lwm lub vaj huam sib luag yuav tsis cuam tshuam. Qhov no ua rau lub kaw lus ua haujlwm tau zoo dua thiab yooj ywm dua, txawm hais tias tus nqi pib tuaj yeem siab dua.
c. Lub Tshuab Hloov Pauv Sib Xyaws
Lub inverter hybrid yog ib hom inverter uas tsis yog tsuas yog hloov DC mus rau AC xwb tab sis kuj tseem tuaj yeem tswj kev khaws cia lub zog hauv cov roj teeb. Qhov no yog qhov tshwj xeeb tshaj yog rau cov tshuab off-grid lossis hybrid, qhov twg lub zog hnub ci tuaj yeem khaws cia thiab siv thaum lub hnub tsis ci.
5. Cov Txheej Txheem Hloov DC mus rau AC
Cov txheej txheem tseem ceeb ntawm lub inverter yog hloov cov hluav taws xob ncaj qha (DC) mus rau cov hluav taws xob hloov pauv (AC). Qhov no ua tiav los ntawm ntau kauj ruam kev siv tshuab:
a. Kev Kho Tam Sim No
Kauj ruam thawj zaug yog kev kho qhov tam sim no, qhov twg lub inverter hloov cov tam sim no ncaj qha (DC) mus rau hauv cov tam sim no hloov pauv (AC). Qhov no ua tiav los ntawm kev siv lub qhov hloov digital uas qhib thiab kaw sai heev, hloov qhov kev taw qhia ntawm cov tam sim no kom nws zoo li cov tam sim no hloov pauv.
b. Kev lim dej
Cov hluav taws xob AC nyoos uas tsim los ntawm cov txheej txheem kho kom raug tseem muaj qhov tsis ruaj khov thiab kev cuam tshuam loj heev. Yog li ntawd, nws yuav tsum tau lim thiab ua kom du kom tsim tau cov hluav taws xob AC huv si thiab ruaj khov. Cov txheej txheem lim dej no suav nrog kev siv ntau yam khoom siv hluav taws xob xws li capacitors thiab inductors.
c. Kev Hloov Kho Lub Teeb Liab
Cov hluav taws xob AC uas tsim tawm yuav tsum tau hloov kho kom haum rau tus qauv zaus thiab voltage siv hauv tsev neeg, feem ntau yog 50Hz lossis 60Hz nrog lub voltage ntawm 120V lossis 240V, nyob ntawm cov cai hluav taws xob hauv zos. Cov txheej txheem modulation teeb liab ua kom ntseeg tau tias cov hluav taws xob AC uas tsim tawm ua tau raws li cov qauv no, ua rau nws muaj kev nyab xeeb thiab sib xws nrog cov khoom siv hluav taws xob hauv koj lub tsev.
6. Kev Ua Haujlwm Zoo thiab Kev Nyab Xeeb ntawm Inverter
Kev ua haujlwm tau zoo yog ib qho tseem ceeb ntawm lub inverter. Cov inverters niaj hnub no tuaj yeem ua tiav kev hloov pauv tau zoo heev, txhais tau tias ib feem tseem ceeb ntawm lub zog tsim los ntawm cov vaj huam sib luag hnub ci tuaj yeem siv tau zoo hauv tsev. Tsis tas li ntawd, kev nyab xeeb kuj yog ib qho tseem ceeb. Cov inverters yuav tsum muaj ntau yam kev nyab xeeb los tiv thaiv lub kaw lus los ntawm kev nce hluav taws xob, kev thauj khoom ntau dhau, thiab lwm yam xwm txheej tsis zoo.
