Kev sib cav ntawm DC thiab AC cov neeg txhawb nqa tau ploj mus ntev. Thaum kaj ntug ntawm kev siv hluav taws xob, cov teeb meem ntawm kev thauj mus los ntawm hluav taws xob tau sib tham heev. Kuv xav paub seb cov hluav taws xob niaj hnub no yuav zoo li cas yog tias muaj qhov hluav taws xob tas li hauv qhov hluav taws xob? Tab sis cov proponents ntawm alternating tam sim no yeej, thiab tam sim no koj yuav tsum siv ntau yam circuits los hloov nws. Ntau ntawm lawv tau dhau los ua classic thiab tau siv dav hauv kev tsim ntau yam khoom siv.
Ib tug ncej hauv hluav taws xob thiab hluav taws xob yog DC rectifier. Nws yog ib qho nyuaj rau overestimate cov txiaj ntsig ntawm nws siv, qhov hluav taws xob tas li yog qhov tsim nyog rau lub zog yuav luag txhua yam khoom siv. Xws li lub hwj chim yog tsim nyog rau kev ua haujlwm ntawm cov khoom siv hauv tsev. Nws yog dav siv hauv kev tsim khoom.
Cov txheej txheem kev sib txuas ntawm diode classic, thov rau lub sijhawm los ntawm Hertz, rau lub sijhawm ntevtsis tau thov. Muaj lus piav qhia txog qhov no, siv plaub lub diodes los kho qhov AC voltage yog yam tsawg kawg nkaus. Thaum lub sij hawm ntawd, cov khoom ntawm semiconductors tau kawm me ntsis, thiab lub tshuab nqus tsev vacuum yog kim heev. Lub DC rectifier saib txawv thiab nws qhov kev ua tau zoo nyob deb ntawm qhov zoo tagnrho.
Qhov xwm txheej tau hloov pauv ntau nrog qhov tshwm sim ntawm cov khoom siv semiconductor. Ntau yam rectifier circuits tau tshwm sim, txhua tus muaj nws tus kheej zoo thiab qhov tsis zoo. Tab sis DC rectifier raws li Hertz Circuit Court tseem yog qhov kev ntseeg siab tshaj plaws. Qhov tsis zoo ntawm cov cuab yeej no suav nrog nws qhov ntev thiab kev ua haujlwm qis. Nws ntseeg tau tias cov peev txheej no tau sau raws li lub npe hu ua linear scheme.
Ib daim duab sib txawv kiag li tau pom nyob rau hauv cov khoom siv rectifier sib sau ua ke raws li cov txheej txheem tsis-linear. Qhov kev vam meej tshaj plaws, raws li kev xyaum tau pom, tau hloov cov khoom siv hluav taws xob. Lawv tsis muaj tag nrho cov kev tsis zoo nyob rau hauv cov khoom siv linear rectifier, tab sis lawv muaj lub suab nrov ntawm cov zis thiab tsis tshua muaj kev ntseeg siab hauv kev ua haujlwm. Xws li DC rectifier tawg ntau zaus, vim tias lawv cov khoom tsim tau cuam tshuam nrog ntau cov khoom siv.
Lub zog semiconductor diodes sib sau ua ke rau hauv tus choj diode tuaj yeem siv los sib sau ua ke DC vuam rectifier. Cov cuab yeej zoo li no yooj yim ua nrog koj tus kheej tes. Diodes los ntawm 250 Amperes thiab siab dua yog mounted raucua sov dab dej. Lawv yog mounted rau ib tug nruj textolite puag. Cov cathodes ntawm cov khoom siv txuas nrog ua ke, qhov no yuav yog qhov ntxiv. Cov anodes kuj tau txuas nrog siv cov phaj tooj liab ua ke, qhov no yuav yog qhov rho tawm ntawm cov cuab yeej. Nws muab tawm ob khub ntawm diodes. Qhov kawg ntawm txhua tus khub kuj tau txuas nrog ua ke nrog tooj liab tuav tsim los nqa lub vuam loj tam sim no. Lawv tau muab nrog alternating voltage los ntawm vuam transformer. Koj tau sib sau ua ke ib lub cuab yeej uas tuaj yeem muab qhov ncaj qha tam sim no rau lub nra. Lub vuam tshuab rectifier siv rau hauv Circuit Court yog txhim khu kev qha txaus los muab lub sijhawm ua haujlwm ntev rau tag nrho cov cuab yeej.
