Nyob rau hauv lub ntiaj teb niaj hnub no, peb cia siab rau ntau hom hluav taws xob chargers los txhawb peb cov khoom siv, xws li smartphones thiab laptops mus rau cov khoom siv hauv tsev thiab cov tshuab ua haujlwm. Ob yam ntawm cov khoom siv ntau tshaj plaws yog AC chargers (alternating tam sim no chargers) thiab DC chargers (direct tam sim no chargers). Thaum ob hom siv los them cov khoom siv hluav taws xob, lawv ua haujlwm sib txawv thiab ua haujlwm sib txawv. Kev nkag siab txog qhov sib txawv tseem ceeb ntawm AC thiab DC chargers yog qhov tseem ceeb rau kev xaiv lub charger zoo rau koj cov khoom siv thiab xyuas kom lawv ua haujlwm tau zoo thiab muaj txiaj ntsig.
Kab lus no yuav ua tib zoo saib ntawm AC thiab DC chargers, piav qhia txog lawv txoj haujlwm, lawv ua haujlwm li cas, lawv qhov zoo thiab qhov tsis zoo, thiab yuav xaiv hom zoo rau koj li cas.
1. Dab tsi yog AC Charger?
Ib AC charger yog ib qho khoom siv uas hloov pauv tam sim no (AC) los ntawm lub qhov hluav taws xob ntawm phab ntsa mus rau qhov hluav taws xob ncaj qha (DC) kom them cov khoom siv hluav taws xob xws li smartphones, laptops, thiab lwm yam khoom siv roj teeb. AC hluav taws xob los ntawm daim phiaj hluav taws xob tsis haum rau kev siv hluav taws xob feem ntau ncaj qha, vim tias feem ntau cov khoom siv hluav taws xob ua haujlwm ntawm DC. Yog li, AC charger ua raws li tus choj hloov pauv tam sim no rau hauv DC khov kho uas lub cuab yeej xav tau ua haujlwm.
Lub AC Charger ua haujlwm li cas?
Kev hloov pauv AC rau DC : Thaum koj ntsaws lub AC charger rau hauv lub qhov hluav taws xob, cov hluav taws xob ntws los ntawm cov xov hlau yog nyob rau hauv daim ntawv ntawm alternating tam sim no (AC). Lub charger ces siv cov khoom siv hu ua rectifier los hloov AC hluav taws xob mus rau DC, uas yog hom tam sim no uas feem ntau cov khoom siv yuav tsum tau them lawv cov roj teeb.
Voltage Regulation : Tom qab hloov dua siab tshiab, lub charger xyuas kom meej tias cov zis hluav taws xob tau hloov kho kom haum raws li qhov xav tau ntawm lub cuab yeej.
