1. Raws li cov zis AC fais fab zaus kev faib tawm, nws tuaj yeem muab faib ua cov zaus inverter, nruab nrab zaus inverter thiab siab zaus inverter. Lub zog zaus inverter yog inverters nrog zaus ntawm 50 txog 60 Hz; intermediate zaus inverters feem ntau muaj zaus ntawm 400 Hz mus rau ntau tshaj kaum kHz; High zaus inverters feem ntau muaj ntau tshaj kaum kHz rau MHz.

2. Raws li tus naj npawb ntawm cov theem tso tawm los ntawm inverter, nws tuaj yeem muab faib ua ib zaug -theem inverter, peb-phase inverter thiab multi-phase inverter.

3. Raws li qhov chaw nyob ntawm inverter lub zog tso zis, nws tuaj yeem muab faib ua active inverters thiab passive inverters. Ib qho inverter uas xa cov hluav taws xob tawm ntawm lub inverter mus rau cov kab hluav taws xob muaj hu ua active inverter; ib qho inverter uas tso tawm lub zog tso tawm los ntawm lub inverter mus rau qee lub zog thauj khoom yog hu ua passive inverter Device.

4. Raws li daim ntawv ntawm inverter lub ntsiab Circuit Court, nws tuaj yeem muab faib ua ib zaug -tiav inverters, thawb- rub inverters, ib nrab -bridge inverters thiab tag nrho-bridge inverters.

5. Raws li hom inverter lub ntsiab hloov khoom siv, nws tuaj yeem muab faib ua thyristor inverters, transistor inverters, field effect inverters, thiab insulated gate bipolar transistor (IGBT) inverters. Nws tuaj yeem muab faib ua ob pawg: "semi-tswj" inverter thiab "tag nrho- tswj" inverter. Tus qub tsis muaj tus kheej - kaw lub peev xwm, thiab cov khoom poob tswj tom qab lawv qhib. Yog li ntawd, nws yog hu ua "semi-tswj" zoo tib yam thyristor. Ob leeg rau thiab tawm tuaj yeem tswj tau los ntawm kev tswj cov electrode, yog li nws yog hu ua "tag nrho tswj hom". Fais fab teb cov nyhuv transistors thiab insulated rooj ob - nyhav transistors (IGBT) 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; Nyob rau tom kawg, DC tam sim no yuav luag tas li thiab cov tswv yim tam sim no yog qhov hloov pauv square nthwv dej.

7. Raws li hom inverter tswj, nws tuaj yeem muab faib ua zaus hloov pauv (PFM) inverter thiab pulse width modulation (PWM) inverter.

8. Raws li hom kev ua haujlwm ntawm lub inverter hloov hluav taws xob, nws tuaj yeem muab faib ua resonant inverters, tsau - zaus nyuaj- hloov inverters thiab tsau - zaus mos- hloov inverters.

9. Raws li tus txheej txheem inverter commutation, nws yuav muab faib ua load commutated inverter thiab tus kheej -hloov inverter.
