Muaj ntau txoj hauv kev hauv qab no raulithium roj teebvoltage boosting:
Boosting method:
Siv boost chip:qhov no yog txoj kev txhawb nqa ntau tshaj plaws. Lub zog nti tuaj yeem nce qhov qis qis ntawm lub roj teeb lithium mus rau qhov xav tau ntau dua voltage. Piv txwv li, yog tias koj xav tsa lub3.7V lithium roj teebvoltage mus rau 5V los muab lub zog rau lub cuab yeej, koj tuaj yeem siv lub zog tsim nyog nti, xws li KF2185 thiab lwm yam. Cov chips no muaj kev hloov pauv siab, tuaj yeem ruaj khov nyob rau hauv cov ntaub ntawv ntawm cov tswv yim voltage hloov nyob rau hauv cov zis ntawm lub teeb boost voltage, lub peripheral Circuit Court yog kuj yooj yim, yooj yim rau tsim thiab siv.
Txais yuav transformer thiab lwm yam circuits:Boost voltage yog pom tau los ntawm electromagnetic induction txoj cai ntawm transformer. Lub DC tso zis ntawm lithium roj teeb yog thawj zaug hloov mus rau AC, ces qhov voltage yog nce los ntawm transformer, thiab thaum kawg lub AC yog rectified rov qab mus rau DC. Txoj kev no yuav siv tau rau qee lub sijhawm uas yuav tsum muaj hluav taws xob siab thiab lub zog, tab sis cov qauv tsim hluav taws xob yog qhov nyuaj, loj thiab kim.
Kev siv lub twj tso kua mis:charge twj tso kua mis yog ib lub voj voog uas siv cov capacitors ua lub zog cia khoom kom paub qhov kev hloov pauv voltage. Nws tuaj yeem sib ntxiv thiab nce qhov hluav taws xob ntawm lub roj teeb lithium, piv txwv li, nce qhov hluav taws xob ntawm 3.7V mus rau qhov hluav taws xob ntawm ob zaug lossis ntau dua. Charge twj Circuit Court muaj qhov zoo ntawm kev ua haujlwm siab dua, me me, tus nqi qis, tsim nyog rau qee qhov chaw siab dua thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob me me.
Bucking Methods:
Siv daim npav chip:Buck nti yog ib qho tshwj xeeb kev sib koom ua ke uas hloov cov hluav taws xob ntau dua mus rau qhov qis dua. Raulithium roj teeb, qhov voltage nyob ib ncig ntawm 3.7V feem ntau yog txo kom tsawg voltage xws li 3.3V, 1.8V kom tau raws li qhov yuav tsum tau ntawm cov khoom siv hluav taws xob sib txawv. Cov chips feem ntau suav nrog AMS1117, XC6206 thiab lwm yam. Thaum xaiv ib tug phaw nti, koj yuav tsum xaiv raws li cov zis tam sim no, voltage sib txawv, stability thiab lwm yam tsis.
Series tsis kam voltage divider:Txoj kev no yog los txuas cov resistor nyob rau hauv series nyob rau hauv Circuit Court, yog li ntawd ib feem ntawm qhov voltage tee ntawm tus resistor, yog li paub qhov txo ntawm lithium roj teeb voltage. Txawm li cas los xij, qhov cuam tshuam ntawm qhov txo qis ntawm txoj kev no tsis ruaj khov thiab yuav cuam tshuam los ntawm kev hloov pauv ntawm cov khoom thauj tam sim no, thiab cov resistor yuav siv qee lub zog, ua rau lub zog pov tseg. Yog li, txoj kev no feem ntau tsuas yog tsim nyog rau lub sijhawm uas tsis tas yuav tsum muaj qhov tseeb ntawm qhov hluav taws xob siab thiab cov khoom me me tam sim no.
Linear voltage regulator:Linear voltage regulator yog ib qho cuab yeej uas paub txog qhov tso zis hluav taws xob ruaj khov los ntawm kev kho qhov ntsuas qhov ntsuas ntawm transistor. Nws tuaj yeem ua kom ruaj khov lithium roj teeb hluav taws xob mus rau qhov yuav tsum tau muaj qhov ntsuas hluav taws xob, nrog cov khoom siv hluav taws xob ruaj khov, tsis tshua muaj suab nrov thiab lwm yam zoo. Txawm li cas los xij, qhov ua tau zoo ntawm cov kab hluav taws xob hluav taws xob qis qis, thiab thaum qhov sib txawv ntawm cov khoom siv hluav taws xob thiab cov zis hluav taws xob loj, yuav muaj ntau lub zog poob, ua rau muaj hluav taws kub ntau dua.
