Daim ntawv thov lub ntsiab ntawm qhov rectifier yog hloov AC zog rau DC fais fab. Txij li txhua lub cuab yeej hluav taws xob yuav tsum siv DC, tab sis lub tuam txhab hluav taws xob' s lub zog hluav taws xob yog AC, yog li tshwj tsis yog siv roj teeb, txhua cov khoom siv hluav taws xob muaj qhov txuas tawm sab hauv.
Raws li rau qhov voltage hloov dua siab tshiab ntawm DC fais fab mov, nws muaj ntau yam ntxiv nyuaj. Ib txoj kev ntawm DC-DC hloov dua siab tshiab yog los xub hloov lub hwj huam mov rau AC (siv cov cuab yeej siv hu ua inverter), tom qab ntawd siv hluav taws xob hloov mus hloov AC voltage, thiab thaum kawg kho nws rov mus rau DC lub zog.
Rectifiers tseem siv nyob rau hauv qhov ntau cov kev hloov kho (AM) xov tooj cua los kuaj pom. Cov teeb liab yuav raug nthuav dav (ua kom muaj zog ntawm lub teeb liab) ua ntej kuaj pom. Yog tias nws tsis nthuav dav, yuav tsum siv cov diode uas muaj qhov hluav taws xob tsawg kawg. Thaum siv qhov txhim kho qhov ntsuas ntawm qhov hluav taws xob, lub capacitor thiab load resistance yuav tsum ua kom zoo. Yog hais tias lub capacitance yog qhov tsawg heev, ntau dhau ntawm qhov muaj peev xwm yuav raug xa mus, thiab loj dhau lawm yuav tswj hwm lub teeb liab.
Cov khoom siv txuas hluav taws xob tseem siv los muab lub zog ruaj khov qhov xav tau rau lub tshuab hluav taws xob. Cov khoom tawm tam sim no hauv Circuit Court qee zaum xav tau tswj hwm. Lub sijhawm no, thyristor (hom ntawm thyristor) yog siv los hloov lub diode hauv tus choj txuas, thiab nws qhov tso tawm hluav taws xob tau hloov kho los ntawm txoj kev ntsuas theem tswj.
Thyristors tseem tseem siv tau nyob rau hauv ntau theem ntawm kev siv tsheb ciav hlau hauv kev ua haujlwm kom ua tiav kev ua kom zoo ntawm cov tsheb sib tsoo. Thyristors tua hluav taws xob (GTO) tuaj yeem siv los tsim hluav taws xob AC ntawm DC lub zog hluav taws xob. Piv txwv, tus qauv no yog siv los muab lub zog rau peb-theem kev tsheb nqaj hlau ntawm Eurostar tsheb ciav hlau.
