Lub hauv paus ntsiab lus ntawm lub xov tooj txawb charger

Lub hauv paus ntsiab lus ntawm lub xov tooj txawb charger:

Ua ntej, kho qhov tsawg zaus (50Hz) AC rau DC, thiab tom qab ntawd siv FET (sib npaug rau qhov hloov ntawm qhov hloov pauv) tig lub DC hloov mus rau qhov siab zaus (tsawg KHz) AC teeb liab, thiab tom qab ntawd hloov nws los ntawm lub transformer. Rectified rau DC. Lub hom phiaj ntawm qhov no yog txhawm rau txo qhov loj ntawm cov khoom sib nqus, piv txwv li transformer. 220 AC rectification, ces pib nrog ib tug oscillating circuit (feem ntau nws tus kheej excited), ua ib tug high-frequency teeb liab ntawm ntau kaum ntawm kilohertz, thiab ces hloov nws mus rau hauv ib tug tsawg-voltage high-frequency ntawm ob peb volts los ntawm ib tug cais high-frequency. transformer me me kom lim thiab ruaj khov Xovxwm thiab tom qab ntawd tso zis 5-6 volts DC (hauv xov tooj) kom them lub xov tooj. Zoo ib yam li cov hloov hluav taws xob me me, lub hwj chim zaus transformer (lub cev hnyav transformer) yog qhov ua tau zoo thiab lub teeb yuag.

Niaj hnub no lub xov tooj ntawm tes chargers feem ntau siv lithium-ion roj teeb. Thaum nws los txog rau lub roj teeb lithium-ion no, cia peb qhia luv luv rau nws. Lub roj teeb lithium-ion yog lub roj teeb uas siv cov khoom siv carbon uas tuaj yeem nqus tau thiab tshem tawm lithium ions ua cov khoom siv tsis zoo electrode. Lub cim ion yog Li-ion. Lub roj teeb feem ntau yog tsim los ntawm cov ntsiab lus tseem ceeb xws li cov khoom siv hluav taws xob zoo, cov hluav taws xob tsis zoo, cov khoom sib cais, thiab cov electrolyte.

Cov txheej txheem them nyiaj ntawm lithium-ion roj teeb tau muab faib ua ob kauj ruam: thawj zaug, kev them nyiaj tam sim no tsis tu ncua, nws qhov tam sim no tsis tu ncua, thiab qhov hluav taws xob tsis tu ncua. Thaum qhov hluav taws xob tau them rau 4.2V, nws tau hloov mus rau qhov kev them nyiaj tas li, thiab qhov hluav taws xob tsis tu ncua thaum lub sijhawm them nyiaj tas li. Nws tau txais me me thiab me dua kom txog thaum cov nqi them tam sim no tsawg dua tus nqi preset. Yog li ntawd, thaum ib tug neeg siv tus nqi ncaj qha los them lub roj teeb ntawm lub xov tooj ntawm tes, nws yog qhov tseeb tias lub hwj chim zaub puv, tab sis cov zaub tseem them. Qhov tseeb, qhov hluav taws xob tau mus txog lub sijhawm no. 4.2V yog li lub hwj chim tso tawm kom pom tag nrho, ces nws yog nyob rau hauv tus txheej txheem ntawm tas li voltage them.

Vim li cas koj thiaj xav tau kev them nyiaj tas li? Nws tsis txaus kom them ncaj qha rau 4.2V nrog qhov tam sim no tas li. Qhov tseeb, nws yog ib qho yooj yim los piav qhia, vim hais tias txhua lub roj teeb muaj ib qho kev tiv thaiv sab hauv. Thaum them nrog qhov tam sim no mus rau 4.2V, qhov 4.2V no tsis yog qhov tseeb ntawm lub roj teeb, tab sis qhov sib npaug ntawm qhov hluav taws xob ntawm lub roj teeb ntxiv rau qhov hluav taws xob siv los ntawm lub zog sab hauv ntawm lub roj teeb. Yog tias qhov tam sim no loj, qhov hluav taws xob tau siv rau ntawm lub hauv paus kuj tseem loj, yog li ntawd yog lub roj teeb tiag tiag. Qhov hluav taws xob yuav tsawg dua 4.2V, yog li siv cov txheej txheem them nyiaj tas li kom maj mam txo cov nqi them tam sim no, yog li qhov tseeb voltage ntawm lub roj teeb yog ze rau 4.2V.

Thaum lub xov tooj ntawm tes them, lub charger thawj zaug hloov 220V AC rau hauv high-voltage DC los ntawm lub rectifier Circuit Court, thiab tom qab ntawd hloov mus rau hauv high-frequency high-voltage mem tes los ntawm lub raj hloov, thiab tom qab ntawd dhau los ua qhov qis-voltage mem tes los ntawm lub transformer. Tus nqi tshwj xeeb ntawm qhov tsis tshua muaj hluav taws xob nyob ntawm cov khoom siv yuav tsum tau them. Qhov hluav taws xob. Thaum kawg, qhov tsawg voltage mem tes dhau los ntawm rectification thiab voltage stabilization Circuit Court thiab dhau los ua tus coj tam sim no. Uas yog hais tias, cov txheej txheem los ntawm 220V AC mus rau 5V DC yuav tsuas yog dhau los ntawm rectifier Circuit Court, transformer, voltage regulator circuit, thiab lwm yam. Lub charger tsuas yog hloov daim ntawv ntawm hluav taws xob hluav taws xob.
