Vim li cas cov ntaub qhwv fais fab hu ua kab
Qhov laj thawj yog vim li cas txoj kev ua kom lub cev tawm yog hu ua "linear" yog vim tias kev sib raug zoo ntawm nws cov zis hluav taws xob thiab cov tswv yim voltage yog linear.
Nyob rau hauv cov ntaub ntawv fab, cov tswv yim voltage yog nce (los yog nce qib) los ntawm transformer, thiab cov zis voltage yog nyob ruaj khov los ntawm txoj kev tswj hwm kab. Tawm Regulators tswj cov zis voltage los ntawm kev kho kom haum rau thiab tawm cov khoom siv hluav taws xob xws li cov raj lossis cov tauv taws los tswj kev ruaj khov.
Tus txheej txheem ua hauj lwm ntawm txoj kev siv hluav taws xob linear kuj yooj yim, thiab cov khoom siv hluav taws xob uas tau hloov kho ncaj qha rau hauv cov zis hluav taws xob. Thaum cov tswv yim voltage hloov, cov ntaub qhwv hluav taws xob linear muab cov zis hluav taws xob los ntawm cov kev tswj hluav taws xob ntawm cov zis hluav taws xob tsis tu ncua.
Vim tias qhov tseeb tias cov txheej txheem kev cai ntawm cov kev cai lij choj ntawm cov khoom siv hluav taws xob yog ua raws linear kev sib raug zoo, lawv tau hu ua "linear" fais fab. Ntawm qhov tod tes, hloov lub zog fais fab kho cov zis hluav taws xob los ntawm kev hloov ua ntawm hloov cov cuab yeej, thiab lawv cov cai ua haujlwm tsis yog linear.
Txawm hais tias cov khoom siv hluav taws xob tau muab cov khoom tawm dag zog tawm, lawv txoj kev siv hluav taws xob tsawg heev vim tias cov khoom siv hluav taws xob siv ntau npaum li cas. Qhov no tseem yog ib qho ntawm cov laj thawj yog vim li cas hloov cov khoom siv fais fab muaj ntau dua hauv cov ntawv thov kev ua haujlwm siab.
Dab tsi Transformer yog qhov zoo rau cov khoom siv hluav taws xob linear
Cov khoom siv hluav taws xob cov hluav taws xob feem ntau siv transformers rau voltage hloov dua siab tshiab.
Rau linear fais fab khoom, nws yog ib qho tsim nyog los xaiv cov hloov pauv uas tsim nyog kom tau raws li cov khoom siv hluav taws xob kom ua tau. Nov yog qee cov ntsiab lus tseem ceeb rau kev xaiv tus transformer:
1. Ua kom muaj hwj chim rau lub zog: Ua ntej, nws yog qhov tsim nyog los txiav txim siab lub zog theem yuav tsum tau los ntawm cov ntaub so fais fab. Thaum xaiv cov transformer, lub hwj chim yuav tsum tau siab dua li qhov siab tshaj plaws uas yuav tsum tau los ntawm cov ntaub pua hluav taws xob kom paub tseeb thiab txhim khu kev qha lub zog hloov dua siab tshiab.
2. Txheeb xyuas cov tswv yim / cov zis hluav taws xob: xaiv cov hloov pauv raws li cov tswv yim thiab cov zis voltage yuav tsum muaj ntawm cov khoom siv hluav taws xob linear. Cov tswv yim voltage yuav tsum sib phim cov tswv yim ntawm lub zog hluav taws xob, thaum cov zis voltage yuav tsum phim cov zis uas yuav tsum muaj ntawm lub zog.
3. Cov zaus txuam: Xav txog cov kev ua haujlwm ntawm cov khoom siv hluav taws xob linear thiab xaiv cov hloov pauv nrog tib yam lossis zoo sib xws. Feem ntau, cov feem pua ntsuas ntawm tus hloov pauv yuav tsum phim cov kev ua haujlwm ntawm lub zog hluav taws xob.
4. Muaj peev xwm tam sim no: Tam sim no muaj peev xwm ntawm cov kev hloov pauv yuav tsum ua kom tau raws li qhov siab tshaj plaws tam sim no yuav tsum tau los ntawm cov ntaub so haujlwm. Xyuas kom meej tias qhov ntsuas nyob tam sim no ntawm tus hloov pauv yog loj dua lossis sib npaug nrog kev ua haujlwm tam sim no ntawm lub zog hluav taws xob kom tsis txhob muaj ntau dhau thiab ua kom puas.
5. Lub zog poob: Nkag siab txog lub zog hluav taws xob los xyuas kom ntseeg tau tias ua tau zoo thiab ruaj khov ntawm lub zog. Xaiv lub transformer nrog lub zog tsis muaj zog kom txo lub zog thaum lub zog hloov dua siab tshiab.
