Dab tsi yog qhov txawv ntawm qhov siab -Cov khoom siv hluav taws xob ntau zaus thiab AC Hloov Cov Khoom Siv Hluav Taws Xob?
High zaus hloov hluav taws xob thiab AC hloov hluav taws xob yog ob hom khoom siv hluav taws xob sib txawv, uas muaj qee qhov sib txawv ntawm lawv cov qauv kev ua haujlwm, daim ntawv thov teb, qhov zoo thiab qhov tsis zoo. Cov hauv qab no yuav muab cov lus piav qhia ntxaws txog qhov sib txawv ntawm ob hom khoom siv fais fab no.
Ua ntej, lub hauv paus ntsiab lus ntawm kev ua haujlwm siab - zaus hloov lub hwj chim mov yog siv siab - zaus hloov cov raj los ua cov kev hloov pauv kom ua tiav cov haujlwm ntawm lub zog, thaum AC hloov hluav taws xob hloov pauv DC los ntawm AC fais fab mov. Cov khoom siv hluav taws xob hloov pauv ntau zaus feem ntau siv cov khoom siv hluav taws xob- lub xeev hloov khoom siv (xws li MOSFETs, IGBTs, thiab lwm yam) rau kev hloov pauv, uas tuaj yeem ua tiav siab - zaus hloov ua haujlwm thiab tso tawm qhov hluav taws xob ruaj khov DC. AC switching fais fab mov tau txais qhov yuav tsum tau DC voltage tso zis los ntawm cov txheej txheem xws li rectification, filtering, thiab kev hloov los ntawm inputting AC voltage.
Qhov thib ob, siab - zaus hloov cov khoom siv hluav taws xob feem ntau yog siv hauv cov khoom siv hluav taws xob, xws li khoos phis tawj, xov tooj ntawm tes, TV, thiab lwm yam khoom siv hauv tsev thiab khoom siv sib txuas lus. Lawv lub luag haujlwm tseem ceeb yog muab cov khoom siv DC ruaj khov. Cov khoom siv hluav taws xob hloov hluav taws xob AC tau siv dav hauv kev lag luam, xws li cov khoom siv hluav taws xob zaus, cov khoos phis tawj siv hluav taws xob, UPS cov khoom siv hluav taws xob, nrog rau cov khoom siv hluav taws xob rau cov khoom siv hauv tsev. AC hloov fais fab mov feem ntau yog siv los hloov cov hluav taws xob hauv hluav taws xob rau DC, thiab tuaj yeem siv rau ntau yam kev xav tau.
Tsis tas li ntawd, muaj qhov sib txawv ntawm kev ua haujlwm siab ntawm - zaus hloov cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hloov AC. Cov khoom siv hluav taws xob hloov pauv ntau zaus muaj qhov ua haujlwm ntau dua thiab ua haujlwm zoo dua piv rau AC hloov hluav taws xob khoom siv. Vim qhov kev hloov pauv ceev ceev ntawm qhov siab - zaus hloov cov khoom siv hluav taws xob, kev hloov hluav taws xob sai dua tuaj yeem ua tiav, yog li txo lub zog poob. Kev khiav hauj lwm zaus ntawm AC hloov cov khoom siv hluav taws xob yog qhov tsawg, ua rau lub zog poob qis.
Tsis tas li ntawd, siab - zaus hloov cov khoom siv hluav taws xob txawv ntawm AC hloov cov khoom siv hluav taws xob raws li qhov ntim thiab qhov hnyav. Cov khoom siv hluav taws xob hloov hluav taws xob ntau zaus feem ntau yog siv cov qauv tsim me me, nrog lub ntim me me, sib dua, thiab yooj yim nqa mus los thiab teeb tsa. Txawm li cas los xij, AC hloov cov khoom siv hluav taws xob xav tau ntau yam kev sib txuas thiab kev tsim hluav taws xob, ua rau muaj qhov ntim loj dua thiab hnyav dua. Qhov no ua rau AC hloov hluav taws xob tsis zoo rau cov ntawv thov nrog qhov chaw txwv thiab qhov hnyav hnyav hauv qee qhov xwm txheej.
Thaum kawg, muaj qhov sib txawv ntawm kev ntseeg siab thiab tus nqi ntawm siab - zaus hloov cov khoom siv hluav taws xob thiab AC hloov cov khoom siv hluav taws xob. Cov khoom siv hluav taws xob hloov pauv ntau zaus muaj kev ntseeg siab thiab yooj yim kom ua tiav cov kev tswj tsis siv neeg thiab kev tiv thaiv kev ua haujlwm vim yog siv cov khoom siv siab heev- lub xeev hloov cov khoom siv thiab kev tswj cov tshuab. Ntawm qhov tod tes, AC hloov cov khoom siv hluav taws xob yog qhov yooj yim, yooj yim rau kev siv thiab tswj, tab sis lawv qhov kev ntseeg siab yog qhov tsawg. Tsis tas li ntawd, kev tsim khoom thiab cov txheej txheem yuav tsum muaj siab - zaus hloov cov khoom siv hluav taws xob yog siab, yog li tus nqi feem ntau yog siab, thaum AC hloov cov khoom siv hluav taws xob tsawg.
Hauv cov ntsiab lus, muaj qee qhov sib txawv ntawm qhov siab - zaus hloov cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hloov hluav taws xob hauv cov ntsiab lus ntawm kev ua haujlwm, thaj chaw thov, kev ua tau zoo, ntim thiab qhov hnyav, kev ntseeg tau, thiab tus nqi. Kev nkag siab txog qhov sib txawv no tuaj yeem pab peb xaiv hom khoom siv hluav taws xob tsim nyog thiab siv nws tsim nyog hauv cov xwm txheej sib txawv kom tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob.
