Lub hwj chim mov (12 V) nrog nws tus kheej txhais tes. Lub hwj chim mov Circuit Court unit 12 Volt

Fais fab mov 12 volt fais fab mov yuav cia rau zoo twg hauv tsev kws, xws li txawm tias ib tug laptop. Thov nco ntsoov tias cov laptop yog cov tswv yim voltage 19 volts. Tab sis nws yuav ua hauj lwm cia li zoo yog hais tias koj tuav lub ntxuav ntawm 12. Txawm li cas los, lub siab tshaj plaws tam sim no ntawm 10 Amps. Tsuas yog rau tej qhov tseem ceeb noj los heev tsis tshua muaj, qhov nruab nrab yog khaws cia nyob rau hauv 2-4 amps. Ib yam yuav tau xav txog - nrog ib tug txheej txheem hloov fais fab mov siv lub tsev ua ua-nyob rau hauv roj teeb yuav tsis ua hauj lwm. Tseem, lub hwj huam mov mus rau 12 lub volts yog zoo tagnrho, txawm rau xws li ib tug ntaus ntawv.

Fais fab mov tsis

Qhov tseem ceeb tshaj tsis muaj ib yam hwj huam mov - nws yog tso zis voltage thiab tam sim no. Lawv qhov tseem ceeb yog nyob ntawm seb ib tug - los ntawm cov hlau siv nyob rau hauv lub thib ob winding ntawm lub transformer. Rau cov lus qhia yuav ua li cas rau kev xaiv nws yuav tsum tau tham ib tug me ntsis rau yav tom ntej. Rau kuv tus kheej, koj yuav tsum txiav txim siab nyob rau hauv ua ntej lub hom phiaj uas koj npaj yuav siv lub hwj huam mov ntawm 12 volts. Yog hais tias koj xav tau faiv fab tso lub uas tsis muaj-power apparatus - navigators, LEDs, thiab hais txog, nws yog txaus mus tso zis 2-3 amps. Thiab qhov no yuav tsum yog ib tug ntau.

Tab sis, yog hais tias koj npaj yuav siv nws mus nqa tawm loj kev nqis tes ua - piv txwv li, them lub roj teeb ntawm lub tsheb, koj yuav tsum tau tawm 6-8 amps. Them tam sim no yuav tsum tau kaum lub sij hawm tsawg tshaj li lub peev xwm ntawm lub roj teeb - qhov no yuav tsum tau yuav tsum coj mus rau hauv tus account. Yog hais tias muaj yog ib tug yuav tsum tau mus cuag lub pab kiag li lawm, lub mov voltage uas yog ho sib txawv los ntawm lub 12 Volt, nws yog tsim nyog los muab cov kev haum.

Yuav ua li cas los xaiv tus transformer

Tus thawj lub caij - ib tug voltage converter. Transformer yuav pab tau txia ua lub AC voltage ntawm 220 volts rau tib lub amplitude, tab sis tus nqi yog heev me me thiab. Thaum tus heev tsawg, koj xav tau ib tug me me nqi. Rau high-hwj chim rau lwm raws li ib lub hauv paus peb yuav noj lub transformer TS-270. Nws muaj hwj chim, txawm muaj 4 windings, uas qhov teeb meem rau 6.3 volts txhua. Lawv siv lub tshuab nqus tsev hlab rau cua sov cov khoom noj. Yooj yim tawm ntawm nws, koj yuav ua tau lub hwj huam mov 12 Volt 12 Amp, uas muaj peev xwm txawm them lub roj teeb ntawm lub tsheb.

Tab sis yog hais tias koj tsis tag txaus nrog nws winding, nws yog tau tawm tag nrho cov theem nrab, tawm hauv tsuas yog tus network. Thiab los tuav lub winding nyob ntawm tej. Qhov teeb meem yog li cas los xam yuav tsum tau tus xov tooj ntawm koj lem. Rau no peb yuav siv ib tug yooj yim muab xam tswvyim - suav tus xov tooj ntawm windings comprises ib theem winding uas ua 6.3 volts. Tam sim no cia li faib 6.3 los ntawm cov xov tooj ntawm koj lem. Thiab koj tau txais ib voltage nqi, uas yuav tsum tau muab tshem tawm nrog ib tug hluas voj hlau. Nws tseem raug nyob tsuas xam ntau npaum li cas koj yuav tsum poob lub coils tau qhov hluav taws xob 12.5-13 volts. Nws yuav txawm zoo dua yog tias cov qhov tso zis yuav tsum nyob rau 1-2 volts ntau dua li cov kev kawm voltage.

Qhuav rectifier

Yuav ua li cas yog ib tug rectifier, thiab dab tsi yog nws rau? Qhov no ntaus ntawv yog raws li nyob rau hauv semiconductor diodes, uas yog ib tug transducer. Nrog nws, ib tug alternating tam sim no yog hloov dua siab tshiab rau DC. Rau kev tsom xam ntawm lub rectifier theem siv ib tug oscilloscope dlaim phaj. Yog hais tias koj pom nyob rau hauv pem hauv ntej ntawm lub diodes sinusoid tom qab lawv yuav tsum zoo tiaj kab. Tab sis tus me daim ntawm cov sine yoj yuav tseem nyob twj ywm. Muab tshem ntawm lawv tom qab.

Los ntawm cov kev xaiv ntawm diodes yuav tsum tau noj nrog lub utmost seriousness. Yog hais tias lub hwj huam mov mus rau 12 lub volts yog siv raws li ib tug roj teeb zaryadchika, qhov yuav tsum tau siv cov ntsiab uas nws rov qab tam sim no tus nqi mus rau 10 amperes. Yog hais tias peb npaj siab yuav mus nqa tawm tsawg-voltage fais fab mov ntawm cov kev pab, nws yog txaus yuav tsim ib tug choj. Ntawm no muaj nqis rau ib tug nres. Preference yog muab rau tus rectifier Circuit Court, sau los ntawm hom choj - plaub diodes. Yog hais tias peb xav tau lub tib semiconductor (ib nrab-yoj Circuit Court), lub hwj huam mov efficiency yog txo los ntawm yuav luag ib nrab.

lim module los ua ke

Tam sim no, thaum cov qhov tso zis muaj ib tug DC voltage, nws yog tsim nyog tias lub thaiv daim duab ntawm lub hwj chim ntawm 12 volts twb me ntsis tuaj. Rau lub hom phiaj no nws yog tsim nyog los siv cov ntxaij lim dej. Faiv fab tso lub tsev khoom siv siv LC-saw txaus. Nyob rau nws yog tsim nyog los qhia rau ntau yam. Yuav kom qhov zoo tawm ntawm qhov rectifier theem yog kev cob cog rua inductance - throttle. Tus tam sim no yuav tsum dhau los ntawm nws, qhov no yog thawj pom theem. Tom ntej no los lub thib ob - ib tug electrolytic capacitor nrog peev xwm loj (ntau txhiab microfarads).

Tom qab lub reactor yog kev cob cog rua rau lub zoo electrolytic capacitor. Nws ob zis txuas nrog rau hauv av (rho tawm). Lub essence ntawm lub electrolytic capacitor yog hais tias nws tso cai rau koj kom tshem tau ntawm tag nrho cov AC tivthaiv. Nco ntsoov tias, nyob rau ntawm lub tso zis hauv lub rectifier tau tej daim me me ntawm ib tug sine yoj? Ntawm no, nws yog tsim nyog los tau tshem ntawm nws, los yog lub hwj huam mov 12 Volt 12 Amp yuav cuam tshuam nrog rau cov pab kiag li lawm kev cob cog rua rau nws. Piv txwv li, lub xov tooj cua los yog cov xov tooj cua yuav emit ib tug muaj zog buzz.

Stabilization ntawm cov zis voltage

Rau cov stabilization ntawm cov zis voltage tsuas siv tau ib tug semiconductor caij. Qhov no yuav ua tau ib tug diode nrog ib tug ua hauj lwm voltage ntawm 12 volts, thiab ntau niaj hnub thiab sophisticated los ua ke hom LM317, LM7812. Tsis ntev los no tsim rau voltage stabilization nyob rau hauv 12 volts. Yog li ntawd, txawm nyob rau hauv cov mob uas cov qhov tso zis rectifier theem 15 volts tom qab stabilization yuav tsuas 12. Tus so mus rau hauv tshav kub. Qhov no txhais tau tias nws yog qhov tseem ceeb rau nruab ib lub stabilizer rau lub radiator.

voltage cai 0-12 V

Rau ntau dua versatility ntawm lub ntaus ntawv yuav tsum siv ib tug yooj yim Circuit Court uas yuav yuav tsum tau ua nyob rau hauv ob peb feeb. Qhov no yuav muab los siv los ntawm txhais tau tias ntawm lub yav tas los hais LM317 los ua ke. Tsuas yog qhov txawv ntawm lub Circuit Court switching hom stabilization yog me me. Lub so nyob rau hauv lub hlau, uas mus rau Rho tawm, hloov nce mus nce los resistor 5 ohms. Nruab nrab ntawm lub qhov hluav taws xob los ua ke thiab ib tug nce mus nce los resistor muaj kuj hais txog 220 ohms. Ib tug ntawm cov tswv yim thiab tso zis ntawm stabilizer rov qab voltage tiv thaiv - cov semiconductor diode. Yog li, lub hwj huam mov ntawm 12 volts, lub ob txhais tes sau, hloov dua siab tshiab rau hauv multifunction ntaus ntawv. Tam sim no nws tseem tsuas ua kom nws los ua ke thiab calibration ntawm lub scale. Thiab koj yuav ua li cas tso zis rau muab tso rau lub tshuab hluav taws xob voltmeter, nyob rau hauv uas thiab saib tam sim no voltage.
