Itshaja ekhaya ibhetri ibhetri imoto: schemes, imiyalelo

Kweli nqaku uza kufunda ngendlela yokwenza ngezandla zabo ekhaya kwitshaja ukuba ibhetri yemoto. Schemes uyakwazi ukusebenzisa ngokupheleleyo nayiphi na kodwa ukhetho elula ngisho nokuveliswa yeyunithi unikezelo lwamandla computer. Ukuba ngaba une-unit ezinjalo, isicelo siya kufumana kulula kakhulu. Ukuba unikeze i motherboard esebenzisa amandla ombane ayi-5, 3.3, volts 12. Njengoko unokuthelekelela, nomdla kuni na lombane volts 12. Itshaja uya kuvelisa iibhetri ezibiza, amandla leyo isusela ukusuka 55 ukuya kwiiyure-ampere 65. Ngamanye amazwi, kuya kuba ngokwaneleyo uyitshaje iibhethri yeemoto ezininzi.

General umbono schema

Ukwenza saa, kufuneka uthathe ithuba inkqubo thaca kweli nqaku. Ibhetri itshaja, kunye ngezandla zakhe ukusuka PSU ye computer yakho wenza lula ukulawula ombane output kunye yokutshaja current. Kufuneka uhlawule ingqalelo into yokuba kukho ukhuseleko elifutshane yesekethe - fuse 10 Amp. Kodwa akunyanzelekanga ukuba yifake, njengoko uninzi computer PSU na isixhobo yokuvikela amvalele xa uthe lweempazamo. Ngoko ke, iitshaja wesiphaluka zitshajwe ukusuka kwiikhompyutha BP unako ngokwabo ukhuselwe circuit elifutshane.

Shih-isilawuli (DA1 kubonisiwe), ngokuqhelekileyo kwi BS isebenzisa iindidi ezimbini - KA7500 okanye TL494. Ngoku ithiyori kancinane. Ikha normal ibhetri recharge unit computer amandla? Impendulo - mhlawumbi neebhetri elikhokelayo iimoto ezininzi nomthamo 55-65 Ah. A abize eqhelekileyo kuba ufuna current we-10% ye umthamo kwebhetri - hayi ngaphezulu kwe 6.5 amperes. Ukuba umbane amandla abangaphezu kwama-150 W, ikhonkco walo "+12" uyakwazi ukunika yangoku efana.

Isanda kokulungiswa

Ukuphinda ibhetri itshaja ekhaya-ezenziwe lula, kufuneka ukuba ube ngcono unikezelo lwamandla:

1. Fumana lahlani bonke iingcingo ezingeyomfuneko. Ngoncedo lwe ngentsimbi ngelotha ukususa kubo, ukuba ungayingeni indaba.
2. Ngokutsho scheme thaca kwi sihloko siyazi resistor esisigxina R1, apho kuyimfuneko unsolder kwaye endaweni yayo ukuseka ukumelana trimmer 27 ohms. Kwi qha eliphezulu resistor ngoko ke kufuneka ukuba ufake i ombane rhoqo "+12". Ngaphandle akuyi kuba nako ukusebenza ifowuni.
3. yesiphaluka output 16-th le olusuka thabatha.
4. Okulandelayo, kufuneka disunite th 15 no-14 kwizigqibo th.

Kakhulu elula ifunyenwe ngcono itshaja ibhetri yemoto. Uyakwazi ukusebenzisa nasiphi na isikimu, kodwa kulula ukwenza esuka PSU kwikhompyutha - kuba lula, kulula ukuyisebenzisa, ifikeleleke ngakumbi. Ukuba thelekisa kunye isixhobo sombane, ubunzima isixhobo yahluke kakhulu (kunye nobukhulu).

esilungiswe itshaja

Udonga ngasemva yeyunithi umbane computer ngoku uya kuba ngaphambili, kungakuhle ukuba bavelise umsebenzi kwezinto (PCB efanelekileyo). Olu donga kufuneka ufake i sokutshajisa somlawuli lwangoku, okhethwe Scheme R10. ingqiqo zangoku resistor kungcono isetyenziswa enamandla kangangoko kunokwenzeka - thatha ezimbini kumandla ka-5 W kunye ukungawi 0.2 ohms. Kodwa konke oko kuxhomekeke ezikhethiweyo inkqubo tshaja ukuba iibhetri zitshajwe. Kwezinye yoyilo, akukho mfuneko yokuba ukusebenzisa resistor amandla.

Xa uqhagamshele ukwanda ezinxuseneyo ngamandla ifunyenwe izihlandlo ezibini, yaye uxhathiso uba ilingana no 0.1 ohms. Udonga ngaphambili kwakhona zizalathisi - voltmeter kunye ammeter, ezivumela ukulawula parameters achaphazelekayo kwitshaja. Kuba ulungiso kakuhle trimmer zaryadchika wasebenzisa ngayo ombane lusetyenziswa 1 st kwimveliso Shi isilawuli.

hardware Requirements

Ziziphi izinto ezifunekayo wenza kwitshaja ekhaya ukuba ibhetri yemoto? indibano yokugqibela scheme iya kuxoxwa ngezantsi. Ukuze kupheliswe uqhagamshelwano umzimba okungafunwayo unikezelo lwamandla wire eqhelekileyo circuit yokutshaja (inxalenye sele iqokelelwe kuni), kufuneka ukuba ukucoca yoshicilelo indlela. Iyunithi umbane yezindlu eyenziwe ngenkcenkce, yaye ngenxa yezizathu zokhuseleko akunakwenzeka ukuba ahlawulise yesekethe ibhetri wayenaye uxhulumaniso galvanic. Kwaye okona kubalulekileyo - oku umnyinyiva womserbia ekumfimfitheni yesekethe yangoku (ngokudlula resistor R11). Ngexesha ukusebenza, indlela yesiphelo mazingabhidaniswa - oko enokuwona zaryadchik.

ibandla lokugqibela

K 1, 14, 15 kunye ezinjengeetheminali 16 soldered wire obhityileyo balahleke. Le ukwambathisa ukuba kufuneka oluthembekileyo, ukuba umthwalo zange ngumsindo, kungenjalo kwitshaja imoto ekhaya lutshitshe. Emva kwendibano ukufaka trimmer lombane 14 volts (+/- 0.2). Yiyo le kwempixano kuyinto eqhelekileyo womserbia ibhetri. Ngaphezu koko, eli xabiso kufuneka iduma (akukho umthwalo enxulumene).

On the ngcingo adibanayo kwi ibhetri, kufuneka ufake umboniso ezimbini nengwenya. Enye ezibomvu, enye emnyama. Ezi zingathengwa kuyo nayiphi na impahla bawagcine kunye namalungu auto. Nantsi uzenzele elula ujikele Charger ukuba ibhetri yemoto. iikhompawundi Scheme: emnyama edityaniswe lokususa, kwaye bomvu ezakhayo. Inkqubo ehlaselayo ezenzekelayo ngokupheleleyo, koncedo lomntu iyafuneka. Kodwa ke kubalulekile ukuqwalasela inqanaba iphambili yale nkqubo.

Inkqubo ukutshajisa

Xa umjikelo voltmeter yokuqala ayinakubonisa lombane malunga 12,4-12,5 V. Ukuba ibhetri ithe amandla ka 55 Yeha, ngoko ufuna ukutshintsha iinqanam de de ammeter ubonisa ixabiso 5.5 Amps. Oku kuthetha ukuba ndibuvelela yangoku 5.5 A. Kamsinya nje ibhetri, nokuncipha zangoku kunye ombane uyabaleka eliphezulu. Ngenxa yoko, ekupheleni current ilingana no0, amandla ombane ayi-14 V.

Enoba yintoni yayisetyenziselwa eyimveliso ukhetho kweepateni yokuyilwa iitshaja, umgaqo osebenza kuyafana ngeendlela ezininzi. Xa ibhetri igcwaliswe ngokupheleleyo, ifowuni iqalisa ukuvala self-wokuqhuba yangoku. Ngoko ke musa kukho ingozi yokuba kubonakale kugesi ibhetri. Ngoko ke, i itshaja nga kuqhagamshelaniswa ibhetri kunye ngosuku, iveki, okanye inyanga.

Tips for akaqali

Ukuba awunaso isixhobo ukuba akukho uxolo kufakwa isixhobo yokulinganisa, ukuze nakujikwa. Kodwa oku kuyimfuneko ukwenza isikali for potentiometer - uphawu isikhundla amaxabiso ezibiza yangoku ilingana no 5.5 A no 6.5 A. Kakade, esi ammeter efakiweyo kulula kakhulu - unako abangaboniyo bagcine inkqubo nokungena ukutshaja ibhetri. Kodwa itshaja ibhetri, ezenziwe ngezandla zakhe ngaphandle kokusebenzisa zingaba isebenzisa lula.
