Transformers yog cov khoom siv uas ua si ib lub luag haujlwm tseem ceeb tshaj plaws hauv qhov chaw uas siv hluav taws xob hluav taws xob. Lawv lub hom phiaj tseem ceeb yog tsim hluav taws xob thiab nws cov khoom siv. Nyob rau hauv qhov kev tshwm sim uas tam sim no kis tau nyob rau hauv ntev, nws yuav tsum me me, thaum lub voltage yuav tsum siab. Qhov no tso cai rau kev txuag nqi tseem ceeb. Ntawm qhov tod tes, qhov tseem ceeb voltages xav tau ntau cov ntaub ntawv insulating, uas ua rau cov nqi siab. Transformers yog cov khoom siv uas siv los ua kom muaj qhov tsis sib xws. Nyob rau hauv ib lub ntsiab lus, lawv yog siv nyob rau hauv lub fais fab nroj tsuag ua ntej kom lub voltage, thiab ces txo nws. Ua tsaug rau qhov no, tus neeg siv khoom tau txais qhov zoo tshaj plaws tam sim no rau nws tus kheej.
Feem ntau, peb-theem transformers yog siv. Qhov no tuaj yeem piav qhia los ntawm qhov tseeb tias muaj peb theem hauv cov khoom siv hluav taws xob. Tsawg zaus, ob peb cov khoom siv ib leeg raug teeb tsa, cuam tshuam los ntawm lub hnub qub lossis daim duab peb sab. Qhov kev ua tau zoo ntawm cov transformers tam sim no siv mus txog 99feem pua. Txawm li cas los xij, ib feem tseem ceeb ntawm lub zog poob vim yog cua sov. Vim li ntawd lawv thiaj siv cov tshuab cua txias tshwj xeeb.
Lub network hom transformer circuit (uas yog qhov feem ntau hauv lub neej txhua hnub) yog tsim los ntawm lub hauv paus ntsiab lus uas muaj ntau yam khoom siv hluav taws xob hauv tsev sib txawv hauv qhov sib txawv ntawm qhov voltage. Qee lub sij hawm dhau los, qhov teeb meem tseem ceeb ntawm cov khoom siv no yog qhov hnyav thiab qhov ntev. Yuav kom daws tau nws, tam sim no lub voltage yog rectified, uas yog ces hloov dua siab tshiab rau hauv high-frequency pulses. Tsis tas li ntawd nyob rau hauv lub transformer, lawv raug txo mus rau qhov tsim nyog tsis. Qhov kev daws teeb meem no tso cai rau koj kom txo qis qhov ntsuas tag nrho ntawm lub zog hluav taws xob. Kuj tseem muaj cov khoom siv impulse. Lub hauv paus ntsiab lus ntawm no hom ntawm transformer yog hais tias nws kis tau tus thiaj li hu ua rectangular mem tes. Lub hom phiaj tseem ceeb ntawm cov cuab yeej no yog xa cov pulses yam tsis muaj kev cuam tshuam.
Cov khoom siv yooj yim tshaj plaws los siv yog autotransformers. Thawj thiab theem nrab windings nyob rau hauv lawv yog ncaj qha mus rau ib leeg. Ua tsaug rau qhov no, kev sib txuas hluav taws xob kuj tau txais ntawm lawv, thiab tsis yog ib qho hluav taws xob xwb. Lub winding muaj tsawg kawg yog peb qhov tawm. Los ntawm kev txuas mus rau txhua tus ntawm lawv, ib qho hluav taws xob raug tsim nrog cov ntsuas sib txawv. Cov khoom siv zoo li no yog tus cwj pwm los ntawm kev ua haujlwm siab, txij li kev hloov pauv tsuas yog tshwm sim nrog ib feem ntawm lub zog. Nyob rau tib lub sijhawm, cov circuits ntawm xws li transformers tsis muaj kev sib cais ntawm lawv tus kheej, uas ua rau lawv pheej yig dua. ATyog li ntawd, lawv feem ntau siv rau kev lag luam.
Nyob rau hauv xaus, nws yuav tsum tau muab sau tseg tias transformers yog cov khoom uas kuj muaj ib tug sib cais muaj nuj nqi. Hauv lwm lo lus, lawv pab tiv thaiv hluav taws xob poob rau ib tus neeg thaum tib lub sijhawm kov cov khoom siv hauv av thiab cov khoom siv tsis zoo. Qhov tseeb yog tias, yog tias hloov pauv los ntawm cov cuab yeej no, nws yuav ua tsis tau rau lub voj voog thib ob hu rau "hauv av" thiab ua rau hluav taws xob poob.
