Hnub ci inverters tau faib ua lwm txoj hauv kev

1. Raws li qhov zaus ntawm cov zis AC fais fab, nws tuaj yeem muab faib ua lub zog zaus inverter, nruab nrab zaus inverter thiab high-frequency inverter. Lub zog zaus inverter nrog zaus ntawm 50-60Hz; Qhov zaus ntawm qhov nruab nrab zaus inverter feem ntau yog 400Hz txog ntau tshaj kaum kHz; Qhov zaus ntawm high-frequency inverter feem ntau yog kaum kHz rau MHz.

2. Raws li tus naj npawb ntawm cov theem tso zis los ntawm inverter, nws tuaj yeem muab faib ua ib theem inverter, peb theem inverter thiab ntau theem inverter.

3. Raws li cov kev taw qhia ntawm lub inverter tso zis zog, nws yuav muab faib ua active inverter thiab passive inverter. Lub inverters uas xa cov hluav taws xob hluav taws xob tso tawm los ntawm lub inverter mus rau lub zog hluav taws xob muaj npe hu ua active inverters; Lub inverter uas xa cov hluav taws xob hluav taws xob tawm los ntawm lub inverter rau qee qhov hluav taws xob hluav taws xob hu ua passive inverter.

4. Raws li daim ntawv ntawm lub ntsiab Circuit Court ntawm inverter, nws tuaj yeem muab faib ua ib qho kawg inverter, thawb-rub inverter, ib nrab choj inverter thiab tag nrho choj inverter.

5. Raws li hom kev hloov pauv tseem ceeb ntawm inverter, nws tuaj yeem muab faib ua thyristor inverter, transistor inverter, teb nyhuv inverter thiab insulated rooj vag bipolar transistor (IGBT) inverter. Nws tuaj yeem muab faib ua ob pawg: "semi tswj" inverter thiab "tag nrho tswj" inverter. Tus qub tsis muaj peev xwm tig tawm tus kheej, thiab cov khoom siv poob lawv cov kev tswj hwm tom qab muab tso rau, yog li hu ua "semi tswj" thyristor zoo tib yam belongs rau pawg no; Lub tom kawg muaj peev xwm tig tawm nws tus kheej, uas yog, rau thiab tawm ntawm cov khoom siv tuaj yeem tswj tau los ntawm kev tswj cov electrode, yog li nws yog hu ua "tag nrho tswj". Fais fab teb cov nyhuv transistors thiab insulated rooj vag dual hnyav transistors (IGBTs) nyob rau hauv qeb no.

6. Raws li DC fais fab mov, nws tuaj yeem muab faib ua qhov voltage qhov inverter (VSI) thiab tam sim no qhov chaw inverter (CSI). Nyob rau hauv lub qub, lub DC voltage yog ze li ntawm tas li, thiab cov zis voltage yog ib tug alternating square nthwv dej; Hauv qhov kawg, DC tam sim no yuav luag tas li thiab qhov kis tau tus mob tam sim no yog qhov hloov pauv square nthwv dej.

7. Raws li inverter tswj hom, nws tuaj yeem muab faib ua zaus modulated (PFM) inverter thiab mem tes dav modulated (PWM) inverter.

8. Raws li kev ua haujlwm ntawm inverter hloov hluav taws xob, nws tuaj yeem muab faib ua resonant inverter, ruaj khov zaus hloov inverter thiab tsau zaus mos hloov inverter.

9. Raws li lub inverter commutation hom, nws yuav muab faib ua load commutation inverter thiab nws tus kheej commutation inverter.
