Ua Koj Tus Kheej
Kauj ruam 1: QHOV TSEEB
Raws li peb txhua tus cuam tshuam nrog ntau lub peev xwm roj teeb piv txwv li 3.7v li-po li-ion roj teeb, 6v 9v, 12v, 24v roj teeb kua qaub. Nws tuaj yeem raug them siv nws cov roj teeb hwm tab sis yog tias peb xav saib xyuas tus nqi tam sim no peb yuav tsum yuav qhov ntsuas qhov sib txawv rau cov roj teeb sib txawv, peb yuav tsum ua qee yam rau qhov ntawd, Cov txiv neej peb tuaj yeem ua koj tus kheej uas tuaj yeem ntsuas qib ntawm txhua lub roj teeb hom.
Kauj ruam 2: Resistors
Peb yuav tsum siv ob peb resistors hauv txoj haujlwm no, koj tuaj yeem siv 4 band (+-5%) resistor tab sis 1% muab txiaj ntsig zoo rau koj. Siv 10 lub lauj kaub hloov pauv 1 tig rau cov txiaj ntsig zoo dua.
Kauj Ruam 3: Referance Voltage Source
Peb xav tau qhov tseeb Refrance voltage rau LM339 Quad Comparator IC. peb tuaj yeem siv pheej yig tab sis raug LM336 nws muaj qhov ntsuas hluav taws xob tsawg kawg yog 2.09v raws li TL431 muaj 2.5v, siv LM336 muab rau koj zoo tshaj plaws.
Kauj Ruam 4: LM339 (Quad Comparator IC)
LM339 yog plaub tus lej sib piv IC, Nws muaj plaub tus neeg sib piv ywj pheej.
Kauj Ruam 5: Daim duab qhia chaw
Siv Cov Duab Duab los ua Koj Tus Kheej.
Ua haujlwm:- Ua haujlwm ntawm cov qauv no yog qhov yooj yim LM339 Kev Hloov pauv Shunt Regulator Muab 2.09v ntawm Min Ref qhov hluav taws xob qhov ntsuas hluav taws xob tam sim no tau muab faib ua qee qhov siv Divider Network ntawm plaub tus tiv thaiv 2.09v, 1.56v, 1.04v, 0.52v raws li qhia hauv kab lus daim duab rau plaub tus neeg sib piv ntawm cov tswv yim uas tsis yog-inv, Inverting input yog txuas nrog 10k (10 tig) lauj kaub, qhov hluav taws xob ntawm inverting input tuaj yeem hloov kho los ntawm cov lauj kaub, Thaum qhov hluav taws xob ntawm kev hloov pauv cov tswv yim nce ntxiv (raws li nce ntawm Batt. Voltage) Cov Zis ntawm Cov Sib Piv rub tawm LOW Thaum kawg Lub teeb tig rau,
Kauj ruam 6: Txhua yam ua tiav
Ua Koj Tus Kheej, Yog tias koj muaj teeb meem Koj tuaj yeem Nug Cov Lus Nug.
