Cov inverters sine wave hloov khoyog cov khoom tseem ceeb hauv ntau lub tshuab fais fab, muab lub zog AC txhim khu kev qha rau ntau yam kev siv. Tsab xov xwm no yuav tshawb nrhiav lub tswv yim ntawm cov inverters hloov kho sine wave, lawv cov txiaj ntsig thiab lawv tuaj yeem hloov kho li cas los txhim kho lawv cov kev ua tau zoo.
Lub inverter sine wave modified yog lub inverter fais fab uas hloov DC fais fab los ntawm lub roj teeb lossis lwm qhov chaw fais fab mus rau hauv AC fais fab. Tsis zoo li lub inverter sine wave ntshiab uas tsim cov waveform du thiab sib xws zoo ib yam li cov khoom siv hluav taws xob tseem ceeb, lub inverter sine wave modified tsim cov waveform uas yog qhov kwv yees ntawm sine wave. Txawm hais tias cov waveform no tsis huv npaum li cov sine wave ntshiab, nws tseem tsim nyog rau kev muab hluav taws xob rau cov khoom siv hluav taws xob thiab cov khoom siv feem ntau.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov inverters hloov kho sine wave yog lawv cov nqi tsim nyog. Lawv feem ntau pheej yig dua li cov inverters ntshiab sine wave, ua rau lawv yog qhov kev xaiv nrov rau cov tshuab hluav taws xob tawm thiab cov tshuab hluav taws xob thaub qab. Tsis tas li ntawd, cov inverters hloov kho sine wave muaj peev xwm muab hluav taws xob rau ntau yam khoom siv, suav nrog cov khoom siv resistive xws li cov teeb incandescent thiab cov khoom siv cua sov, nrog rau ntau hom khoom siv hluav taws xob.
Txawm li cas los xij, muaj qee qhov kev txwv rau kev ua haujlwm ntawm cov inverters hloov kho sine wave. Qee cov khoom siv hluav taws xob rhiab heev, xws li qee hom khoom siv suab, yuav tsis ua haujlwm zoo thaum siv lub inverter hloov kho sine wave. Tsis tas li ntawd, cov motors thiab lwm yam inductive loads yuav ua haujlwm tsis zoo thiab tsim suab nrov ntau dua thaum siv lub inverter hloov kho sine wave.
Yuav kom daws tau cov teeb meem no thiab txhim kho kev ua haujlwm ntawm lub inverter modified sine wave, muaj ntau yam kev hloov kho uas ua tau. Ib qho kev hloov kho uas feem ntau yog ntxiv cov lim dej kom du thiab txo qhov kev cuam tshuam ntawm harmonic. Qhov no pab coj cov inverter cov zis ze rau lub sine wave ntshiab, txhim kho nws qhov sib xws nrog cov khoom siv hluav taws xob rhiab heev.
Lwm qhov kev txhim kho ntxiv rau lub inverter modified sine wave yog qhov ntxiv cov hluav taws xob tswj hluav taws xob. Qhov no pab kom lub inverter lub zog hluav taws xob tso zis ruaj khov, ua kom nws tseem nyob hauv qhov kev kam rau siab txawm tias nyob hauv ntau yam kev mob hnyav. Qhov no tseem ceeb heev rau kev muab hluav taws xob rau cov khoom siv hluav taws xob rhiab heev uas xav tau lub zog hluav taws xob ruaj khov.
Ntxiv rau cov kev hloov kho no, muaj ntau txoj kev siv tshuab siab heev uas siv tau los txhim kho kev ua haujlwm ntawm cov inverters sine wave. Piv txwv li, kev ua cov teeb liab digital tuaj yeem siv los tsim cov waveforms kom raug thiab sib xws dua, txo qhov kev cuam tshuam harmonic thiab txhim kho qhov sib xws ntawm inverter nrog ntau yam khoom siv.
Zuag qhia tag nrho, lub inverter sine wave modified yog ib qho kev daws teeb meem uas siv tau ntau yam thiab pheej yig rau kev muab hluav taws xob AC hauv cov tshuab hluav taws xob tawm thiab cov tshuab hluav taws xob thaub qab. Txawm hais tias nws yuav muaj qee qhov kev txwv hauv kev sib raug zoo nrog qee hom khoom siv, ntau yam kev hloov kho tuaj yeem ua kom nws ua tau zoo dua thiab nthuav nws cov ntawv thov. Los ntawm kev siv cov kev hloov kho no, kev ua tau zoo thiab kev hloov pauv ntawm lub inverter sine wave zoo dua tuaj yeem txhim kho, ua rau nws muaj txiaj ntsig zoo dua hauv lub tshuab hluav taws xob.
