Aya mabwiriza azagufasha kuvuga amashanyarazi kugirango ufungure 3-25 V. Niba ufite imbaraga muri mudasobwa igendanwa na 19 V cyangwa akarere ko nk'izi zishobora guhinduka, hanyuma ushireho voltage iyo ari yo yose yo kuzenguruka imenyekanisha rihinduka.
Birakenewe
- Intera ebyiri 470 μf 25 V.
- Kurwanya impinduka 10 com.
- Kurwanya 2.2 com.
Guhindura Ishami rishinzwe gutanga imbaraga hamwe na voltage ihamye mu nkomoko ifite voltage ingirakamaro
Fungura umubiri wahagaritswe hamwe na screwdriver. Birumvikana ko imitsi yose idafite ibishishwa, iyo bifatanye, nubwo wansetsa hano -
Bigaragara amafaranga yose yingufu za pulse.
Ibyo byose ibumoso bwumuhindura ubururu ntituzakoraho. Iki nigice kinini-voltage kandi ntabwo idushimisha. Iburyo, igice gito cyumuyaga kigizwe nibintu byinshi, hano bizatungwa.
Gahunda nigitekerezo cyo kunonosorwa
Igice gifite ubudakemwa kubitekerezo binyuze muri Optocoupler. Iyi Oprone igenzura microciriirizse ya TL431. Ifite ibisabwa 3 kandi isa na transistor.
.
) Umurwanya umwe muri optics urunigi rubuza, izindi ntagererariro ebyiri kumurongo wa chip. Inyuma y'Inama y'Ubutegetsi, aba bazungura baragaragara neza.
Ni ukuvuga, niba uhinduye ibintu byo guhubuka kuri chip, noneho ibisohoka voltage kubisohoka byingufu bizahinduka kandi ibisohoka voltage. Ibi birakenewe kugirango usimburwe Guhuza amavuta. Hafi nkibi:
Turoha abanyamahanga.
Witondere gusimbuza ubushobozi bwo gusohoka mubindi hamwe na voltage yo hejuru.
Na bo barabatererana.
Gutandukanya ibishya.
Tweguriwe umutware 2.2 com, ukurikije inzira yo kunonosorwa.
Dufata itandukaniro, umugurisha insinga.
Tweguriwe insinga mu kibaho aho kuba chip yo kurwanya.
Noneho, witonze cyane, duhindukira igice murusobe tukagenzura akazi. Huza imiyoboro kubisohoka.
Niba ibintu byose bikora neza, noneho dukusanya urubanza. Kubera ko nta mwanya windi uhari, tuzazana hanze hanze tukabimenagura kuruhande rwa kole.
Reba munsi yumutwaro. Inkomoko igengwaga neza kandi ikareka voltage murwego rwa 3.4-21.5 V.
Ibintu byose bikora neza.
Amagambo make yerekeye umutekinisiye ushinzwe umutekano
- Mbere yo gusezererwa, niba warabujije gusa kumurongo, menya neza gutegereza iminota mike kugeza igihe ibintu byose byimbere bisezerewe.
- Ibisohoka voltage, hamwe numwanya muto wo kurwanya impinduka, ntigomba kurenga 25 v, nkuko imbaraga zisohoka zishobora kunanirwa. Kugabanya voltage ihinduka, ongera kurwanya umurwanya 2.2 com.
