Cov khoom siv hluav taws xob txhuasyog cov khoom tseem ceeb hauv ntau yam khoom siv hluav taws xob thiab muaj peev xwm khaws thiab tso tawm lub zog hluav taws xob. Cov capacitors no feem ntau pom muaj nyob rau hauv cov ntawv thov xws li cov khoom siv fais fab, cov hluav taws xob circuits, thiab cov khoom siv suab. Lawv muaj nyob rau hauv ntau yam voltage ratings rau ntau yam kev siv. Txawm li cas los xij, tib neeg feem ntau xav tias nws puas siv tau lub capacitor voltage siab dua es tsis txhob siv lub capacitor voltage qis dua, piv txwv li 50v capacitor es tsis txhob siv 25v capacitor.
Thaum nws los txog rau lo lus nug txog seb lub capacitor 25v puas tuaj yeem hloov nrog lub capacitor 50v, cov lus teb tsis yog yooj yim yog lossis tsis yog. Txawm hais tias nws yuav ntxias kom siv lub capacitor voltage siab dua hloov lub capacitor voltage qis dua, muaj qee yam uas yuav tsum xav txog ua ntej ua li ntawd.
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab txog lub hom phiaj ntawm qhov ntsuas hluav taws xob ntawm lub capacitor. Qhov ntsuas hluav taws xob qhia txog qhov siab tshaj plaws uas lub capacitor tuaj yeem tiv taus yam tsis muaj kev pheej hmoo ntawm kev ua tsis tiav lossis kev puas tsuaj. Kev siv cov capacitors nrog qhov ntsuas hluav taws xob qis dua li qhov xav tau rau ib daim ntawv thov tshwj xeeb tuaj yeem ua rau muaj kev puas tsuaj loj heev, suav nrog lub capacitor tawg lossis hluav taws. Ntawm qhov tod tes, kev siv lub capacitor nrog qhov ntsuas hluav taws xob siab dua li qhov tsim nyog tsis tas yuav ua rau muaj kev pheej hmoo kev nyab xeeb, tab sis nws yuav tsis yog qhov kev daws teeb meem zoo tshaj plaws lossis txuag chaw.
Lwm yam tseem ceeb uas yuav tsum xav txog yog kev siv lub capacitor. Yog tias lub capacitor 25v siv rau hauv lub voj voog uas muaj qhov hluav taws xob siab tshaj plaws ntawm 25v, tsis muaj laj thawj siv lub capacitor 50v. Txawm li cas los xij, yog tias lub voj voog ntsib qhov hluav taws xob nce siab lossis hloov pauv ntau dua li qhov ntsuas 25v, lub capacitor 50v yuav yog qhov kev xaiv zoo dua los xyuas kom meej tias lub capacitor tseem nyob hauv nws qhov kev ua haujlwm nyab xeeb.
Nws tseem ceeb heev uas yuav tsum xav txog qhov loj ntawm lub capacitor. Cov capacitors uas muaj hluav taws xob ntau dua feem ntau loj dua li cov capacitors uas muaj hluav taws xob tsawg dua. Yog tias qhov chaw txwv yog qhov txhawj xeeb, kev siv cov capacitors uas muaj hluav taws xob ntau dua yuav ua tsis tau.
Hauv kev xaus lus, thaum nws muaj peev xwm siv lub capacitor 50v hloov lub capacitor 25v, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov yuav tsum tau ua kom zoo thiab kev nyab xeeb ntawm koj daim ntawv thov tshwj xeeb. Nws yog qhov zoo tshaj plaws los ua raws li cov lus qhia ntawm cov chaw tsim khoom thiab siv cov capacitors nrog qhov ntsuas voltage tsim nyog rau ib daim ntawv thov es tsis txhob pheej hmoo tsis tsim nyog.
Tag nrho hauv txhua yam, thaum nws los txog rau lo lus nug txog seb puas siv tau lub capacitor 50v hloov lub capacitor 25v, cov lus teb tsis yog yooj yim yog lossis tsis yog. Ua ntej txiav txim siab, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov yuav tsum tau ua ntawm lub zog hluav taws xob, kev nyab xeeb, thiab qhov txwv ntawm koj daim ntawv thov tshwj xeeb. Thaum tsis paub meej, nws yog ib qho tseem ceeb kom sab laj nrog tus kws ua haujlwm tsim nyog lossis tus tsim khoom capacitor kom ntseeg tau tias qhov kev daws teeb meem zoo tshaj plaws thiab muaj kev nyab xeeb tshaj plaws rau ib daim ntawv thov.
