Los ntawm kev tswj hwm ntawm thiab tawm ntawm plaub lub tshuab hloov mus, qhov zaus thiab amplitude ntawm cov zis hloov tshiab tuaj yeem hloov kho.
2.2 ib nrab-choj inverter:Nws muaj ob lub tshuab hloov chaw, S1 thiab S2, uas tso tawm cov ib nrab voj voog ntawm lwm lub sijhawm (AC) thaum S1 yog OF thiab S2 yog ON thiab S1 tau tawm. Ib nrab-tus choj inverters muaj cov zis tsawg muaj peev xwm thiab feem ntau yog siv rau cov ntawv thov hluav taws xob tsawg.
3. Tswj cov tswv yim rau ib leeg-theem inverter Circuits
Cov tswv yim tswj hwm rau ib-theem inverter ncig suav nrog cov hauv qab no:
3.1 Mem Tes Dav Teeb (PWM) Tswj:Cov kev cai ntawm lub amplitude thiab zaus ntawm cov zis hloov tshiab tam sim no yog pom tau los ntawm kev kho lub sijhawm thiab tawm lub sijhawm ntawm cov khoom siv hloov. Lub PWM tswj muaj qhov zoo ntawm cov lus teb nrawm nrawm, muaj kev tswj hwm siab tau, thiab cov khoom zoo ntawm cov zis Wirevorm.
3.2 sine yoj tes (SPWM) tswj:Tsim cov cim tswj cov cim los ntawm cov cim qhia txog sine yoj
3.3 Chaw vector kev hloov kho (SVPWM) tswj:Los ntawm kev thov cov txheej txheem tswj ntawm peb-theem inverter rau ib-theem inverter, nws paub txog kev tswj hwm ntawm lub amplitude thiab theem ntawm cov zis hloov tshiab. Lub SVPWM tswj muaj qhov zoo ntawm kev tswj hwm siab thiab zoo ntawm cov zis Wirevorm.
3.4 Kev tswj kev nrhiav tau:Kev tswj hwm lub sijhawm tiag tiag ntawm lub inverter yog pom tau los ntawm kev kwv yees yav tom ntej lub xeev ntawm lub system. Kev tswj kev twv ua ntej muaj qhov zoo ntawm cov muaj zog ruaj khov thiab zoo adaptability.
4. Kev ua tiav Indexes of Tib-Theem Inverter Circuits
Cov kev ua tau zoo ntawm ib-theem inverter Circuit Court tsuas yog suav nrog cov hauv qab no:
4.1 tso zis ntau:Qhov zaus ntawm cov AC tso tawm los ntawm Inverter, uas feem ntau yog tib yam li ntau zaus ntawm cov tswv yim DC cov khoom siv DC.
