Cov hloov pauv tam sim no ua tiav lub luag haujlwm tseem ceeb hauv kev ntsuas thiab saib xyuas hluav taws xob hauv ntau cov ntawv thov. Lawv tau tsim los hloov cov dej siab rau hauv cov qauv no, qis-theem uas tuaj yeem ntsuas tau yooj yim thiab saib xyuas yooj yim. Thaum nws los txog rau cov hloov pauv tam sim no, ob hom loj yog siv tau: AC (hloov pauv tam sim no) thiab DC (DC (kho tam sim no). Nkag siab txog qhov sib txawv ntawm no yog qhov tseem ceeb rau kev xaiv cov hloov pauv tau rau ib daim ntawv thov tshwj xeeb.
Ib qho ntawm thawj qhov sib txawv ntawm AC thiab DC cov hloov pauv tau nyob hauv hom kev tam sim no lawv tau tsim los ntsuas.Ac Tam sim no hloov pauvtau tsim tshwj xeeb los ntsuas kev hloov pauv, uas yog tus cwj pwm los ntawm kev hloov pauv thiab qhov ntau. Cov dej no feem ntau pom nyob rau hauv lub hwj huam faib khoom, cov hluav taws xob hluav taws xob, thiab ntau yam kev siv khoom lag luam thiab cov ntawv thov kev lag luam. Ntawm qhov tod tes,DC Hloov Hloovyog tsim los ntsuas ncaj qha los yog cov dej ntws, uas ntws hauv ib qho kev taw qhia yam tsis tau hloov pauv polarity. Cov dej no feem ntau siv nyob rau hauv cov roj teeb hluav taws xob, hnub ci ntsa iab, thiab qee yam kev muaj cov txheej txheem.
Lwm qhov sib txawv ntawm AC thiab DC cov hloov pauv tam sim no yog lawv kev tsim kho thiab kev tsim qauv. AC tam sim no hloov pauv yog feem ntau tsim nrog cov tub ntxhais ua los ntawm Laminically steel lossis hlau, uas pab tau hloov cov hlau nplaum flux tsim los ntawm kev hloov tshiab. Lub xub ntiag ntawm lub transformer ntawm lub transformer tau txuas nrog lub nra, tso cai rau nws ntsuas qhov tam sim no ntws los ntawm Circuit Court. Hauv kev sib piv, DC cov hloov pauv tam sim no xav tau kev tsim qauv sib txawv vim yog qhov xwm txheej tas li ntawm kev ncaj qha. Lawv feem ntau siv cov tub ntxhais toroidal ua los ntawm cov khoom siv ferromagnetic kom ntseeg tau tias kev ntsuas tau yog ntawm Unidirectional tam sim no.
Hais txog kev ua tau zoo, AC thiab DC cov hloov pauv tam sim no tseem pom sib txawv ntawm lawv cov lus teb raug thiab zaus.Ac Tam sim no hloov pauvYog paub rau lawv qhov tseeb ntawm kev ntsuas kev hloov pauv tsis pub dhau qhov ntau zaus ntau zaus, feem ntau los ntawm 50Hz. Lawv tau tsim los muab cov kev ntsuas cuav hauv qab sib txawv thauj khoom thiab siv dav hlau siv rau hauv kev faib khoom siv thiab hluav taws xob tswj hwm. DC cov hloov pauv tam sim no, ntawm qhov tod tes, tau tsim kho kom raug ntsuas ncaj qha nrog qhov kev cuam tshuam tsawg tsawg nrog kev cuam tshuam tsawg kawg nkaus thiab qib siab. Lawv feem ntau siv nyob rau hauv cov ntawv thov uas yog kuaj xyuas qhov kev saib xyuas ntawm DC tseem ceeb, xws li hauv cov roj teeb them thiab lub zog txuas ntxiv dua.
Thaum nws los txog rau kev nyab xeeb thiab rwb thaiv tsev, AC thiab DC cov hloov pauv tam sim no tseem muaj qhov yuav tsum muaj. Ac Cov hloov pauv tam sim no yog tsim los tiv thaiv cov hluav taws xob siab thiab cov kev mob ntawm cov khoom noj kom sib txawv. Lawv tau nruab nrog rwb thaiv tsev rwb thaiv tsev uas tuaj yeem ua rau cov kev hloov pauv ceev hauv cov hluav taws xob thiab muab kev tiv thaiv hluav taws xob. Hauv kev sib piv,DC Hloov HloovYuav tsum tau cov rwb thaiv tsev tshwj xeeb kom tiv thaiv cov hluav taws xob tsis tu ncua thiab cov kev hloov pauv ntawm polarity cuam tshuam nrog ncaj qha. Qhov no ua kom muaj kev nyab xeeb thiab txhim khu kev qha ua haujlwm ntawm tus transformer hauv DC daim ntawv thov.
Hauv kev xaus, qhov sib txawv tseem ceeb ntawm AC thiab DC cov hloov pauv tam sim no nyob rau hauv hom tam sim no lawv tau tsim los ntsuas, lawv cov yam ntxwv, kev txiav txim siab kev ua tau zoo, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb. Nkag siab cov kev sib txawv no yog qhov tseem ceeb rau kev xaiv cov hloov pauv txoj cai rau ib qho kev thov tshwj xeeb thiab kev txhim khu kev qha ntawm hluav taws xob hauv ntau yam system siv hluav taws xob thiab khoom siv. Seb nws yog rau kev faib khoom siv hluav taws xob, kev siv tshuab, lossis lub zog txuas ntxiv dua, xaiv cov hloov pauv tau tsim nyog tam sim no rau kev ua haujlwm zoo thiab muaj kev nyab xeeb.
