Nws tau ntev tau ib tug tshaj plaws ntawm yav dhau los sib cav tswv yim ntawm AC thiab DC. Nyob rau hauv thaum ntxov hnub ntawm hluav taws xob electrification ntawm tsheb thauj mus los tej teeb meem tau los sib tham tiag. Kuv xav yuav ua li cas yuav zoo niaj hnub hluav taws xob circuits, yog hais tias muaj yog ib tug tsis tu ncua nro nyob rau hauv lub nplos? Tab sis los ntawm UFW ntawm cov AC yeej, thiab hloov nws yog tam sim no tsim nyog los siv sib txawv schemes. Muaj ntau ntawm lawv tau ua classics thiab yog lug siv nyob rau hauv lub tsim ntawm ntau yam pab kiag li lawm.
Ib tug ntawm cov ncej nyob rau hauv qhov hluav taws xob thiab electronics yog DC rectifier. Kev pab los ntawm nws cov kev siv tsis tau overestimated, lub DC voltage tsim nyog rau lub hwj chim zoo tag nrho li. Xws li ib tug khoom noj yog tsim nyog rau lub qub lag luam los ntawm lub tshuab. Nws yog dav siv nyob rau hauv qhov.
Classical diode kev twb kev txuas tswvyim npaj nyob rau hauv vim lub sij hawm los ntawm Hertz, tau ntev lawm tsis siv. Nws yog ua tau kom nrhiav tau ib zajlus kom piav, siv plaub diode rau muab daws kom tiav cov AC voltage yog tsawg kawg yog tsis tau yus. Thaum lub thaj chaw ntawm semiconductors tau me ntsis kawm, thiab lub tshuab nqus tsev hlab heev kim. Rectifier DC ntsia sib txawv, thiab nws tus yam ntxwv nyob deb ntawm zoo tagnrho.
Qhov teeb meem no tau hloov dramatically nrog lub advent ntawm semiconductor pab kiag li lawm. Muaj ntau yam rectifier circuits, txhua yam uas nws tus kheej zoo thiab disadvantages. Tab sis lub DC-raws li Hertz tswvyim tseem yog feem ntau txhim khu kev qha qhov chaw. Qhov tsis zoo ntawm no ntaus ntawv muaj xws li nws zuag qhia tag nrho qhov ntev thiab tsis muaj hauj lwm zoo. Nws yog ntseeg hais tias xws springs tau koom ua ke rau hauv lub thiaj li hu ua linear qauv.
Ib tug txawv kiag li daim duab yog cai nyob rau hauv lub rectifier pab kiag li lawm sau nyob rau hauv ib tug uas tsis yog-linear Circuit Court. Cov vam meej tshaj plaws, raws li qhia, yog switching khoom siv fais fab. Lawv yog deprived ntawm tag nrho cov tsis zoo ntawm cov linear daws kom tiav ntaus ntawv, tab sis muaj ib theem ntawm cov suab nrov tso zis thiab tsawg ntseeg. Tej DC rectifier feem ntau lov, txij li thaum lawv cov khoom yog txuam nrog ib tug loj tus naj npawb ntawm cov ntsiab siv.
Haib semiconductor diodes, tuaj txoos ua ke nyob rau hauv ib tug diode choj, yuav siv tau los sau vuam rectifier DC. Xws li ib tug ntaus ntawv yog yooj yim los mus ua kom nrog koj tus kheej txhais tes. Diodes 250 Amp thiab saum toj no yog mounted rau ib tug thaum tshav kub kub lub dab ntxuav tes. Lawv yog mounted rau ib tug txhav paus ntawm textolite. Cathodes pab kiag li lawm yog kev cob cog rua ua ke, qhov no yuav ua tau ib tug ntxiv. Anodes kuj cob cog rua ntawm tooj liab daim hlau ua ke, nws yuav ua tau ib tug rho tawm ntaus ntawv. Ob tug khub ntawm diodes. Lub xaus ntawm ib khub kuj cob cog rua ua ke Shinko tooj liab, xam rau lub khiav ntawm loj vuam tam sim no. Lawv noj nrog alternating voltage ntawm lub vuam transformer. Koj tau sau ib tug ntaus ntawv muaj peev xwm ntawm loading loj cov ntaub ntawv mus rau hauv ib tug tib neeg tam sim no. Rectifier rau vuam siv lub tshuab siv nyob rau hauv lub tswvyim, sufficiently robust los xyuas kom meej ib tug ntev kev khiav hauj lwm lub sij hawm rau tag nrho cov ntaus ntawv.
