Hloov DC mus rau AC: Nkag siab txog thev naus laus zis thiab nws cov ntawv thov
Hauv lub ntiaj teb niaj hnub no, qhov twg kev siv hluav taws xob zoo thiab kev ruaj khov yog qhov tseem ceeb tshaj plaws, thev naus laus zis DC-AC inverter tau dhau los ua ib qho tseem ceeb hauv ntau yam kev siv. Tsab xov xwm no yuav saib ze dua txog seb DC-AC inverters ua haujlwm li cas, lawv qhov tseem ceeb, thiab lawv ntau yam kev siv.
Lub inverter DC rau AC yog dab tsi?
Lub inverter DC-AC yog ib lub cuab yeej hluav taws xob uas hloov cov hluav taws xob ncaj qha (DC) mus rau cov hluav taws xob hloov pauv (AC). Qhov kev hloov pauv no yog qhov tseem ceeb vim tias feem ntau cov khoom siv hauv tsev thiab cov khoom siv hauv kev lag luam siv lub zog AC. Lub inverter tau txais DC input (piv txwv li, los ntawm lub roj teeb, lub hnub ci vaj huam sib luag, lossis lub roj teeb roj) thiab hloov nws mus rau AC output, ua rau nws siv tau rau txhua hnub.
Lub inverter ua haujlwm li cas?
Kev ua haujlwm ntawm DC mus rau AC inverter muaj ntau yam tseem ceeb thiab cov txheej txheem. Hauv nws lub hauv paus, lub inverter siv ntau lub qhov hloov hluav taws xob (feem ntau yog transistors) los tsim cov nthwv dej square lossis cov nthwv dej sine modified. Cov txheej txheem pib los ntawm kev nkag mus rau hauv DC voltage rau hauv lub inverter, uas tom qab ntawd qhib thiab kaw sai sai los tsim cov nthwv dej AC.
Muaj ntau hom inverters, suav nrog:
1. Cov Inverters Square Wave: Cov inverters no tsim cov zis square wave yooj yim, tsis ua haujlwm zoo, thiab tuaj yeem ua rau cov khoom siv hluav taws xob rhiab heev puas tsuaj.
2. Cov Inverters Hloov Kho Sine Wave: Lawv tsim cov waveform uas kwv yees li sine wave, ua rau lawv sib xws nrog ntau yam khoom siv.
3. Cov inverters sine wave ntshiab: Cov inverters no tso tawm cov sine wave du heev, ze rau lub zog uas lub tuam txhab fais fab muab. Lawv zoo tagnrho rau cov khoom siv hluav taws xob rhiab heev thiab cov khoom siv ua haujlwm zoo.
Inverter DC rau AC Daim Ntawv Thov
Qhov ua tau ntau yam ntawm inverter DC-to-AC thev naus laus zis ua rau nws siv tau rau ntau yam kev siv, suav nrog:
1. Cov Tshuab Fais Fab Hnub Ci: Ib qho ntawm cov ntawv thov tseem ceeb tshaj plaws ntawm DC rau AC inverters yog nyob rau hauv cov tshuab fais fab hnub ci. Lub zog DC tsim los ntawm cov vaj huam sib luag hnub ci yuav tsum tau hloov mus rau AC fais fab ua ntej nws tuaj yeem siv los ntawm cov tsev thiab cov lag luam. Cov inverters ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj zog ntau tshaj plaws thiab xyuas kom meej tias lub zog hnub ci tau koom ua ke rau hauv lub grid.
2. Lub Tshuab Fais Fab Tsis Txuas (UPS): Lub inverter yog ib feem tseem ceeb ntawm lub UPS system, muab hluav taws xob thaub qab thaum lub sijhawm hluav taws xob tsis ua haujlwm. Lub inverter hloov cov hluav taws xob ncaj qha (DC) uas khaws cia rau hauv lub roj teeb mus rau hauv hluav taws xob hloov pauv (AC), kom ntseeg tau tias cov khoom siv tseem ceeb tseem ua haujlwm tau.
3. Tsheb Fais Fab (EV): Cov inverters yog qhov tseem ceeb hauv tsheb fais fab, hloov cov hluav taws xob ncaj qha los ntawm lub roj teeb tsheb mus rau hauv cov hluav taws xob hloov pauv kom tsav lub cev muaj zog hluav taws xob. Qhov kev hloov pauv no yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov tsheb fais fab.
4. Cov khoom siv hauv tsev: Ntau yam khoom siv niaj hnub, xws li lub tub yees, cua txias, thiab tshuab ntxhua khaub ncaws, xav tau lub zog AC. Cov inverters tuaj yeem muab lub zog rau cov khoom siv no siv cov roj teeb lossis cov khoom siv hluav taws xob rov ua dua tshiab.
5. Kev Siv Hauv Kev Lag Luam: Cov khoom siv hloov zaus siv dav hauv kev lag luam rau kev tswj lub cev muaj zog thiab kev ua haujlwm tsis siv neeg. Lawv tuaj yeem muab kev tswj qhov ceev sib txawv rau AC motors, yog li txhim kho kev ua haujlwm zoo thiab kev ua tau zoo ntawm cov txheej txheem tsim khoom.
Hauv luv luv
Cov thev naus laus zis Inverter DC-rau-AC yog lub hauv paus tseem ceeb ntawm cov txheej txheem hluav taws xob niaj hnub, ua kom siv tau lub zog rov ua dua tshiab tau zoo thiab muab cov kev daws teeb meem hluav taws xob thaub qab. Thaum lub ntiaj teb txuas ntxiv mus rau kev coj ua kom muaj zog ruaj khov, cov inverters yuav tseem ceeb zuj zus. Kev nkag siab txog cov khoom siv no ua haujlwm li cas thiab lawv cov ntawv thov tuaj yeem pab cov neeg siv khoom thiab cov lag luam txiav txim siab ntse txog kev siv hluav taws xob thiab kev tswj hwm. Txawm hais tias nyob rau hauv cov txheej txheem hluav taws xob hnub ci, tsheb fais fab, lossis kev siv hauv kev lag luam, cov thev naus laus zis inverter DC-rau-AC tab tom paving txoj hauv kev rau yav tom ntej uas siv hluav taws xob tau zoo dua.
