Lub hwj huam inverter (tsheb fais fab tuag) Yog ib lub hwj huam converter uas yuav hloov DC12V ncaj qha mus rau AC220V alternating tam sim no, Nws yog ib yam li lub hwj huam loj. Nws siv tau los ntawm cov hluav taws xob hluav taws xob.

Tus inverter yuav tsum tau ua los ntawm ib tug ntaus ntawv inverter ntaus kom tau hu ua ntawd. Nws yog ncaj qha los ntawm ib transformer. Uas yog hais, Nws yuav twb paub lawm DC input thiab ces tso zis AC. Tus thawj xibfwb ua hauj lwm yog tib yam li ntawd ib switching hwj huam mov, Tiam sis tus oscillation zaus yog nyob rau hauv ib chav ntau yam, piv txwv, yog hais tias qhov frequency yog 50HZ, Tso zis yog AC 50HZ. Tus inverter yog ib tug ntaus ntawv uas yuav hloov nws cov frequency. Yuav xaiv cov UPS fais fab inverter yuav tsum mas them xim rau cov ntsiab lus nram qab no.

1. Tso zis voltage: Tsis pub dhau lub specified fluctuation ntau yam ntawm cov input DC voltage, Nws qhia tus nqi voltage tus nqi uas tus inverter yuav tsum tau tso zis. Cov ruaj khov accuracy ntawm cov zis nyob voltage tus nqi feem ntau muaj cov kev cai raws li cov kev cai: Thaum lub xeev kho mob, Cov voltage fluctuation ntau yam yuav tsum tau txwv, piv txwv, Nws cov deviation yuav tsum tsis pub tshaj ±3% los yog ±5% ntawm tus nqi nyob. Nyob rau hauv dynamic teeb meem uas cov load hloov dheev los yog cuam tshuam dab tsi los ntawm lwm yam cuam tshuam, Cov zis voltage deviation yuav tsum tsis pub tshaj ±8% los yog ±10% ntawm tus nqi nyob.

2. Tso zis voltage imbalance: Raws li tej kev khiav hauj lwm rau cov neeg mob, Cov theem peb-theem voltage imbalance (piv ntawm reverse sequence theem kom zoo sequence) tso zis los ntawm tus inverter yuav tsum tsis pub tshaj tus nqi, feem ntau expressed hauv %, xws li 5 % Lossis 8%.

3. Waveform distortion ntawm cov zis voltage: Thaum cov inverter tso zis voltage yog sinusoidal, Qhov ntau pub waveform distortion (los sis cov ntsiab lus) yuav tsum tau muab cov ntaub ntawv uas yuav tsum tau muab teev tseg. Feem ntau expressed raws li tag nrho waveform distortion ntawm cov zis voltage, Nws tus nqi yuav tsum tsis pub tshaj 5% (10% pub rau ib zaug xwb tso zis).

4. Nyob tso zis frequency the frequency ntawm cov zis AC voltage yuav tsum yog ib tug nqi ruaj khov kuj ruaj khov, Feem ntau cov hwjchim frequency ntawm 50Hz. Tus deviation yuav tsum tsis pub dhau ±1% nyob rau hauv tej yam mob ua hauj lwm.

5. Load fais fab tuag: Characterizes lub inverter muaj peev xwm nqa inductive los yog peev loads. Raws li sine yoj tej yam mob, Lub hwj huam load yog 0.7.0.9 (lag luam), thiab tus nqi nyob 0.9.

6. Tso zis tam sim no: Indicates cov zis tso zis tam sim no ntawm cov inverter nyob rau hauv lub specified load fais fab ntau yam. Ib txhia inverter khoom muab tso zis peev xwm, expressed hauv VA los yog KVA. Lub peev xwm ntawm lub inverter yog thaum lub tso zis fais fab tuag yog 1 (uas yog, purely resistive load), Cov zis tso zis voltage yog qhov khoom ntawm cov zis tso zis tam sim no.

7. Tso zis efficiency: Lub efficiency ntawm tus inverter yog tus piv ntawm nws cov zis tso zis rau lub input fais fab nyob rau hauv specified ua hauj lwm rau cov neeg mob, expressed hauv %. Lub efficiency ntawm lub inverter ntawm nyob tso zis peev xwm yog tag nrho load efficiency, thiab cov efficiency ntawm 10% Cov zis tso zis peev xwm yog tsawg load efficiency.
