Kev Hloov Fais FabPiav Qhia: Cov Zoo thiab Cov Kev Siv
Cov khoom siv hluav taws xob hloov pauv, tseem hu ua hom hloov pauvcov khoom siv fais fab (SMPS), nrov heev thoob plaws ntau yam lag luam vim lawv qhov ua tau zoo thiab yooj ywm. Vim lawv muaj peev xwm hloov pauv lub zog los ntawm ib daim ntawv mus rau lwm daim,cov khoom siv hluav taws xob hloov pauvtau dhau los ua qhov kev daws teeb meem rau ntau yam kev siv xws li cov khoom siv hluav taws xob rau cov neeg siv khoom mus rau cov khoom siv hauv kev lag luam.
Hauv cov khoom siv fais fab linear ib txwm muaj, lub zog raug tswj los ntawm kev tshem tawm lub zog ntau dhau hauv daim ntawv ntawm cua sov, ua rau kev ua haujlwm qis dua. Txawm li cas los xij,cov khoom siv hluav taws xob hloov pauvtau hloov pauv txoj kev lag luam los ntawm kev koom ua ke cov transistors fais fab uas tuaj yeem hloov pauv tau zoo ntawm lub xeev qhib thiab kaw, txo qis kev poob zog. Qhov kev ua haujlwm hloov pauv no ua rau muaj kev ua haujlwm zoo dua thiab txo cov cua sov tsim, ua rau nws zoo tagnrho rau ntau daim ntawv thov.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawmcov khoom siv hluav taws xob hloov pauvyog lawv qhov me me. Qhov txo qis hauv kev poob hluav taws xob tso cai rau kev siv cov khoom me me, ua rau lawv zoo tagnrho rau cov ntawv thov uas muaj qhov chaw txwv xws li cov khoom siv mobile. Tsis tas li ntawd, piv rau cov khoom siv fais fab linear, cov khoom siv fais fab hloov pauv yog qhov hnyav dua, ntxiv rau lawv qhov yooj yim nqa thiab yooj yim siv.
Cov khoom siv hluav taws xob hloov pauvkuj muab ntau yam hluav taws xob nkag, ua rau lawv sib xws nrog ntau yam khoom siv hluav taws xob hauv thaj chaw sib txawv. Qhov kev hloov pauv no ua kom ntseeg tau tias cov khoom siv hluav taws xob tuaj yeem ua haujlwm thoob ntiaj teb yam tsis tas yuav siv cov adapters lossis kev hloov kho ntxiv. Tsis tas li ntawd, cov khoom siv hluav taws xob hloov pauv kuj tseem tuaj yeem tswj tau ntau yam hluav taws xob tso zis, uas tso cai rau lawv kom muaj zog rau ntau yam khoom siv nrog cov kev xav tau hluav taws xob sib txawv.
Hais txog kev ntseeg tau,cov khoom siv hluav taws xob hloov pauvmuaj qhov zoo dua li cov khoom siv fais fab linear. Lawv cov qauv tsim solid-state tshem tawm qhov xav tau cov khoom loj thiab ua tsis tau zoo xws li transformers thiab capacitors. Qhov no thaum kawg ua rau lub neej ua haujlwm ntev dua thiab txhim kho kev ntseeg siab ntawm lub kaw lus tag nrho.
Qhov yooj ywm ntawmcov khoom siv hluav taws xob hloov pauvnthuav dav mus rau lawv ntau yam kev siv. Txij li kev siv hluav taws xob rau cov neeg siv khoom xws li smartphones, laptops, thiab gaming consoles, mus rau ntau daim ntawv thov kev lag luam xws li kev sib txuas lus, aerospace, thiab cov khoom siv kho mob, lawv tsis muaj qhov sib piv hauv lawv qhov kev hloov pauv tau. Tsis tas li ntawd, cov khoom siv hluav taws xob hloov pauv feem ntau siv rau hauv cov tshuab hluav taws xob rov ua dua tshiab xws li cov vaj huam sib luag hnub ci thiab cov cua turbines vim lawv cov kev hloov pauv hluav taws xob siab thiab kev tswj hwm zoo.
Txawm hais tiascov khoom siv hluav taws xob hloov pauvmuaj ntau yam zoo, lawv kuj muaj qee qhov kev txwv. Piv txwv li, lawv yuav ua rau muaj kev cuam tshuam hluav taws xob (EMI) vim yog kev ua haujlwm hloov pauv zaus siab. Txhawm rau kom txo qhov teeb meem no, cov khoom siv lim dej ntxiv feem ntau siv. Tsis tas li ntawd, kev tsim thiab tsim cov khoom siv fais fab hloov pauv xav tau kev paub tshwj xeeb thiab kev txawj ntse kom ntseeg tau tias muaj kev ua haujlwm zoo thiab kev nyab xeeb.
Xaus lus,cov khoom siv hluav taws xob hloov pauvtau hloov pauv kev lag luam fais fab nrog lawv cov kev ua haujlwm siab, me me, thiab kev hloov pauv tau yooj yim. Lub peev xwm hloov pauv lub zog tau zoo thiab cov hluav taws xob nkag thiab tawm dav dav ua rau lawv yog thawj qhov kev xaiv rau ntau daim ntawv thov. Raws li thev naus laus zis txuas ntxiv mus,cov khoom siv hluav taws xob hloov pauvyuav tsis muaj qhov tsis ntseeg ua lub luag haujlwm tseem ceeb hauv kev muab lub zog rau cov khoom siv thiab cov kab ke yav tom ntej.
