Txog cov hom inverter thiab qhov sib txawv

Nyob ntawm seb koj xav tau dab tsi thiab xav tau dab tsi, koj tuaj yeem xaiv ntau hom inverters sib txawv. Cov no suav nrog cov square wave, modified square wave, thiab cov pure sine wave inverter. Lawv txhua tus hloov lub zog hluav taws xob los ntawm DC mus rau hauv alternating current, uas cov khoom siv hluav taws xob siv. Lub inverter kuj tseem tuaj yeem hloov kho kom tsim tau qhov voltage uas koj xav tau.

Yog tias koj xav yuav lub inverter tshiab, koj yuav tsum xam tag nrho cov hwj chim siv ntawm koj cov khoom siv. Qhov ntsuas hwj chim tag nrho ntawm lub inverter piav qhia txog ntau npaum li cas lub cuab yeej tuaj yeem muab 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 hom inverters yooj yim tshaj plaws, lub inverter square wave, hloov lub DC qhov chaw mus rau hauv lub square wave AC tso zis. Lub nthwv dej no muaj qhov hluav taws xob thiab tam sim no tsawg, ua rau nws zoo tagnrho rau cov ntawv thov uas tsis tshua muaj kev cuam tshuam. Nws tseem yog hom inverter pheej yig tshaj plaws. Txawm li cas los xij, lub waveform no tuaj yeem tsim lub suab "humming" thaum txuas nrog cov khoom siv suab. Nws tsis haum rau cov khoom siv hluav taws xob rhiab heev thiab lwm yam khoom siv.

Hom inverter thib ob, lub modified square wave, hloov lub DC source mus ua alternating current. Nws ua haujlwm tau zoo dua li lub square wave, tab sis tsis du zoo li. Hom inverter no siv sijhawm ob peb feeb los pib ua haujlwm. Nws tsis yog qhov kev xaiv zoo rau cov khoom siv uas xav tau kev pib ua haujlwm sai. Tsis tas li ntawd, THD factor (total harmonic distortion) ntawm lub wave tuaj yeem siab, ua rau nws nyuaj rau qee qhov kev siv. Lub wave kuj tseem tuaj yeem hloov kho kom tsim tau lub pulsed lossis modified sine wave.

Cov inverters tuaj yeem tsim nrog ntau yam kev sib txawv ntawm lub zog hluav taws xob, txhua tus daws teeb meem sib txawv. Cov inverters kuj tseem siv tau los tsim cov modified sine waves, pulsed lossis modified square waves, lossis pure sine waves. Koj tuaj yeem xaiv lub voltage-fed inverter, uas muaj cov yam ntxwv ntawm buck-converter. Cov hom inverters no feem ntau me dua, sib dua, thiab pheej yig dua li cov transformer-based inverters.

Cov inverters kuj muaj kev xaiv siv lub voj voog thyristor. Lub voj voog thyristor yog tswj los ntawm lub capacitor commutation, uas tswj cov dej ntws. Qhov no tso cai rau cov thyristors muab lub peev xwm loj hauv kev tswj hwm lub zog. Kuj tseem muaj cov voj voog yuam kev commutation uas tuaj yeem ntxiv rau SCRs.

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

Ntxiv rau cov hom inverters uas tau hais los saum toj no, koj tuaj yeem siv lub inverter tswj lub cev muaj zog zaus hloov pauv kom txhim kho cov waveform thiab kom koj tuaj yeem kho qhov hluav taws xob tso zis. Hom inverter no kuj tseem siv tau ntau yam kev tswj hwm sib txawv los ua kom zoo dua qhov ua haujlwm ntawm inverter.de.
