Ntawm inverter hom thiab qhov sib txawv

Nyob ntawm koj cov kev xav tau tshwj xeeb thiab cov kev xav tau, koj tuaj yeem xaiv los ntawm ntau hom sib txawv ntawm cov inverter.Cov no suav nrog cov square nthwv dej, hloov square yoj, thiab cov ntshiab sine yoj inverter.Lawv txhua tus hloov lub zog hluav taws xob los ntawm DC qhov chaw mus rau qhov hloov pauv tam sim no, uas yog siv los ntawm cov khoom siv.Lub inverter kuj tuaj yeem hloov kho kom tsim tau qhov hluav taws xob uas koj xav tau.

Yog tias koj xav yuav ib lub inverter tshiab, koj yuav tsum suav tag nrho lub zog siv ntawm koj cov khoom siv.Tag nrho lub zog ntsuas ntawm lub inverter piav qhia tias lub zog ntawm lub cuab yeej tuaj yeem muab tau rau lub nra.Qhov no feem ntau yog qhia hauv watts lossis kilowatts.Koj tuaj yeem nrhiav tau lub inverter nrog qhov ntsuas siab rau lub zog siab tshaj plaws, tab sis qhov no feem ntau kim dua.

Ib qho ntawm cov qauv yooj yim tshaj plaws ntawm inverters, square yoj inverter, converts DC qhov chaw rau hauv ib lub voj voog AC tso zis.Cov nthwv dej no kuj tsis tshua muaj hluav taws xob thiab tam sim no, ua rau nws zoo tagnrho rau cov ntawv thov uas tsis tshua muaj siab.Nws tseem yog hom inverter uas pheej yig tshaj.Txawm li cas los xij, cov qauv no tuaj yeem tsim lub suab "humming" thaum txuas nrog cov khoom siv suab.Nws tsis zoo rau cov khoom siv hluav taws xob thiab lwm yam khoom siv.

Qhov thib ob hom inverter, hloov square yoj, converts DC qhov chaw rau alternating tam sim no.Nws muaj txiaj ntsig zoo dua li cov square nthwv dej, tab sis tsis zoo li du.Hom inverter no tuaj yeem siv sijhawm ob peb feeb los ncaws hauv. Nws tsis yog qhov kev xaiv zoo rau cov khoom siv uas xav tau kev pib sai.Tsis tas li ntawd, THD yam (tag nrho harmonic distortion) ntawm nthwv dej tuaj yeem siab, ua rau nws nyuaj rau qee yam kev siv.Lub nthwv dej kuj tuaj yeem hloov kho kom tsim tau lub suab los yog hloov sine yoj.

Inverters tuaj yeem tsim nrog ntau yam sib txawv ntawm lub zog hluav taws xob sib txawv, txhua qhov teeb meem sib txawv.Inverters kuj tuaj yeem siv los tsim cov sine hloov pauv, hloov pauv lossis hloov cov xwm txheej tsis zoo, lossis cov sine tsis huv.Koj tuaj yeem xaiv lub zog-fed inverter, uas muaj cov yam ntxwv ntawm lub tshuab hloov pauv.Cov hom inverters no feem ntau me me, sib dua, thiab tsis tshua kim tshaj li qhov hloov pauv raws li qhov hloov pauv.

Inverters kuj muaj kev xaiv siv lub thyristor circuit.Lub thyristor Circuit Court yog tswj los ntawm ib tug commutation capacitor, uas tswj cov ndlwg ntawm tam sim no.Qhov no tso cai rau cov thyristors muab lub zog loj tuav lub peev xwm.Kuj tseem muaj cov kab hluav taws xob yuam kev uas tuaj yeem ntxiv rau SCRs.

Ib hom thib peb ntawm inverter, multilevel inverter, tuaj yeem tsim hluav taws xob siab AC los ntawm cov khoom siv qis dua.Hom inverter no siv ntau yam sib txawv ntawm qhov sib txawv topologies los txhim kho kev hloov pauv.Nws tuaj yeem ua tau raws li ib qho series lossis parallel circuit.Nws tseem tuaj yeem siv rau hauv lub zog hluav taws xob standby kom tshem tawm qhov hloov pauv hloov mus.

Dhau li ntawm hom inverters uas tau hais los saum toj no, koj tuaj yeem siv qhov sib txawv ntawm lub cev muaj zog tswj inverter los txhim kho lub waveform thiab tso cai rau koj los kho qhov tso zis voltage.Hom inverter no kuj siv tau ntau yam kev tswj cov tswv yim sib txawv los txhim kho lub inverter efficiency.de.
