Kev siv hluav taws xob yooj yim tshaj plaws ob zaug rectification (ob npaug) txoj kev yog siv ob pawg ntawm kev hloov kho ib nrab ntawm nthwv dej kom tsim tawm ob lub zog tsim cov hluav taws xob nrog cov lus qhia sib txawv thiab qhov tsis zoo nrog kev tawm tsam diodes, thiab lim lawv sib cais. Txuas qhov kawg thiab qhov tsis zoo kom tau txais qhov tso tawm voltage ob zaug AC input voltage. Hom Circuit Court no hu ua Delon Circuit (German: Delon-Schaltung). Yog tias tsim nyog, lub Circuit Court no tseem tuaj yeem muab cov hluav taws xob nruab nrab lossis siv tau rau qhov zoo thiab qhov tsis zoo rau lub zog hluav taws xob.
Lub Deron Circuit Court tau piav saum toj no tuaj yeem muab tau los ntawm lwm qhov txawv: ob lub tshuab hluav taws xob txuas rau hauv koob yog siv los ua lim capacitors ntawm qhov tso zis kawg ntawm tus choj rectifier, thiab ib qho hloov tau txuas ntawm qhov nruab nrab ntawm cov lim capacitor thiab ib kawg ntawm AC input. Cov. Thaum tus tes hloov qhov hloov, lub Circuit Court no yuav coj zoo li tus choj txuas qhov qub; thaum tus tes hloov qhov hloov mus, nws yuav dhau los ua aforementioned Deron Circuit Court, ua hluav taws xob voltage Douler rectifier. Piv txwv li, thaum AC tawm tswv yim yog 100 ~ 120V, tus tes hloov qhov hluav taws xob tuaj yeem tig mus; thaum AC tawm tswv yim yog 220 ~ 240V, lub pob nyem tuaj yeem hloov mus; qhov no ua kom yooj yim hloov ntawm txhua lub zog los ntawm lub zog hauv ntiaj teb, uas ua rau kwv yees A DC voltage ntawm 320V (li ± 15%) tuaj yeem nkag mus rau hauv txoj kev hloov pauv yooj yim ntawm lub zog hluav taws xob.
Lub Greinach voltage doubler Circuit tuaj yeem txuas ntxiv qhov sib txuas ntawm diodes thiab cov capacitors los ua cov hluav taws xob voltage nrog ntau qhov ntsuas, hu ua Cockcroft-Walton lub tshuab hluav taws xob Circuit Court (Lus Askiv: Cockcroft-Walton lub tshuab hluav taws xob), lub sijhawm ntawd nws siv nyob rau hauv cov hluav taws xob tawg. Txawm hais tias xws li qhov hluav taws xob voltage doubler Circuit Court tuaj yeem muab qhov hluav taws xob ntau ntau zaus ntawm tus nqi siab ntawm cov tswv yim AC, cov khoom tso tawm tam sim no thiab qhov hluav taws xob tsis xwm yeem. Hom kev siv hluav taws xob ntau ntawm cov xov hluav taws xob feem ntau yog siv los muab qhov hluav taws xob siab rau cathode ray tube (CRT), photomultiplier tube, lossis hluav taws xob yoov tshaj lij cov xov hluav taws xob qub.
Rectifier daim ntawv thov
Daim ntawv thov lub ntsiab ntawm qhov rectifier yog hloov AC zog rau DC fais fab. Txij li tag nrho cov khoom siv hluav taws xob xav tau siv tam sim no ncaj qha, tab sis lub tuam txhab hluav taws xob' s lub zog hluav taws xob tau hloov pauv tam sim no, yog li tshwj tsis yog cov roj teeb siv, cov roj hluav taws xob tsis muaj qhov tsis txaus nyob hauv lub hwj chim muab ntawm txhua cov khoom siv hluav taws xob.
Raws li rau qhov hloov mus rau qhov hluav taws xob ntawm DC lub zog hluav taws xob, nws muaj ntau qhov nyuaj ntxiv. Ib txoj kev ntawm DC-DC hloov dua siab tshiab yog los xub hloov lub zog mus 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 me me ntawm lub teeb liab) ua ntej kev 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 ntov hluav taws xob uas yuav tsum muaj 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 qhov tso zis hluav taws xob tau hloov kho los ntawm txoj kev 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 li, cov qauv no yog siv rau ntawm Eurostar cov tsheb ciav hlau los muab lub zog rau peb-theem kev tsheb ciav hlau. [2]
cua txias txoj kev
Nws muaj peb hom kev siv cua txias rau cov khoom siv kho qhov ncauj: cua txias, ntshiab kiv cua txias, kev sib xyaw ntawm ntuj txias thiab kiv cua txias. Ntuj cua txias muaj cov yam ntxwv ntawm tsis muaj tshuab tsis ua hauj lwm, muaj kev ntseeg siab; tsis muaj cua ntws, tsis tshua muaj plua plav, zoo rau cov cua sov ua kom sov, thiab tsis muaj suab nrov. Lub kiv cua ntshiab txias muaj qhov nyhav thiab cov nqi qis. Kev sib xyaw ntawm cov kiv cua thiab lub tshuab ua kom txias txias muaj cov yam ntxwv ntawm kev txo qis ntim thiab hnyav ntawm cov khoom siv, kev pab lub neej ntev ntawm tus kiv cua, thiab muaj zog muaj peev xwm hloov kho kom tsis ua haujlwm ntxuam.
