Fais fab hluav taws xob hluav taws xob rau ntau lub hom phiaj xav tau qhov hluav taws xob tas li. Hauv kev sib txuas hauv tsev ib txwm siv, qhov tam sim no hloov pauv, nws zaus feem ntau yog 50 Hz. Cov duab ntawm qhov hloov pauv hluav taws xob yog qhov sinusoid nrog lub sijhawm ntawm 0.02 vib nas this, thaum ib nrab-lub voj voog yog qhov zoo txheeb ze rau qhov nruab nrab, qhov thib ob yog qhov tsis zoo. Txhawm rau daws qhov teeb meem ntawm kev hloov nws mus rau tus nqi tas li, AC rectifiers yog siv. Lawv tuaj nyob rau hauv txawv designs thiab lawv designs yuav txawv.
Yuav kom nkag siab tias qhov yooj yim ib nrab-yoj rectifier ua haujlwm li cas, koj yuav tsum xub nkag siab qhov xwm txheej ntawm hluav taws xob conductivity. Qhov tam sim no yog qhov kev taw qhia ntawm cov khoom siv hluav taws xob, uas tuaj yeem muaj qhov sib txawv polarity, lawv tau muab faib ua cov khoom siv hluav taws xob thiab qhov, txwv tsis pub lawv yog cov neeg pub dawb thiab cov neeg txais khoom muaj cov conductivity ntawm "n" thiab "p" hom, feem. Yog tias cov khoom siv nrog n-conductivity txuas nrog lwm tus, p-hom, tom qab ntawd lub npe hu ua p-n hlws ris yog tsim los ntawm lawv tus ciam teb, txwv kev txav ntawm cov khoom siv hauv ib qho kev coj. Qhov kev tshawb pom no tau tso cai siv cov tshuab semiconductor,Hloov cov raj hluav taws xob feem ntau nrog nws.
Ib nrab-yoj rectifier pib muaj lub diode, ib qho khoom siv nrog ib qho p-n junction. Lub alternating voltage ntawm lub input ntawm lub Circuit Court muaj tsuas yog ib nrab ntawm nws nyob rau hauv cov zis, ib tug uas sib haum mus rau cov kev taw qhia ntawm switching rau lub rectifier diode. Qhov thib ob ntawm lub sijhawm, uas muaj qhov sib txawv, tsuas yog tsis dhau thiab "txiav tawm".
Daim duab qhia pom ib theem ib zaug rectifier, feem ntau siv hauv cov khoom siv hauv tsev yooj yim thiab tsim los rau hauv tsev. Hauv kev lag luam ib puag ncig, peb-theem network feem ntau yog siv, yog li AC-rau-DC hloov dua siab tshiab circuits tuaj yeem nyuaj dua. Tsis tas li ntawd, raws li txoj cai, fuses thiab lim tau suav nrog hauv Circuit Court. Ib kauj ruam-down transformer los yog lwm qhov chaw ntawm alternating voltage tuaj yeem hloov tau ntawm cov tswv yim ntawm lub voj voog. Rectifier diodes txawv nyob rau hauv lawv cov tsis, lub ntsiab ntawm uas yog tus nqi ntawm tam sim no rau cov diode tsim.
Ib nrab-yoj rectifier muaj qhov tsis zoo loj piv rau cov nthwv dej puv nkaus. Qhov voltage tom qab rectification tsis tas li, nws pulsates los ntawm tus nqi siab tshaj plaws mus rau xoom nyob rau hauv ib nrab-sine duab ntawm daim duab thiab muaj pes tsawg tus nqi nyob rau hauv lub sij hawm ntawm pulses. Cov khoom siv tsis sib xws no feem ntau yog them nyiaj los ntawm kev suav nrog lub capacitor smoothing ntawm tus nqi loj (qee zaum ntsuas hauv ntau txhiab.microfarads), tsim los rau qhov hluav taws xob tsis tsawg dua qhov tshwm sim ntawm qhov tso zis ntawm Circuit Court, raws li txoj cai, nrog cov npoo. Xws li kev ntsuas kuj tsis muab qhov zoo tagnrho qhov sib npaug ntawm daim duab, tab sis qhov loj ntawm qhov sib txawv ntawm cov nqi teeb tsa tau txo qis, uas ua rau nws muaj peev xwm siv ib nrab-yoj rectifier rau lub zog yooj yim circuits uas tsis tas yuav muaj kev ruaj ntseg siab.
Nyob hauv cov xwm txheej nyuaj, cov txheej txheem hloov kho tag nrho yog siv nrog kev ruaj khov tom qab.
