Hloov chaw: nws yog dab tsi, sib txawv nrog kab, thiab nws yog dab tsi

hloov qhov chaw

Una hloov qhov chaw yog cov cuab yeej siv hluav taws xob muaj peev xwm hloov pauv lub zog hluav taws xob los ntawm kev ua ntu zus hluav taws xob Cheebtsam, xws li transistors, tus tswj hluav taws xob, thiab lwm yam. Ntawd yog, nws yog a fais fab mov, tab sis nrog qhov sib txawv nrog kev hwm rau cov kab tawm. Cov peev txheej no tseem paub tias yog SMPS (Hloov Hom Fais Fab Khoom), thiab tam sim no siv rau ntau qhov kev thov ...

Lub hwj huam mov yog dab tsi

ATX qhov chaw

Una fais fab mov, lossis PSU (Lub Hwj Huam Fais Fab), yog cov cuab yeej siv los xa hluav taws xob kom tsim nyog rau cov khoom sib txawv lossis cov txheej txheem. Nws lub hom phiaj yog kom tau txais lub zog los ntawm cov khoom siv hluav taws xob thiab hloov nws mus rau qhov tsim nyog hluav taws xob thiab tam sim no kom cov khoom sib txuas ua haujlwm tau zoo.

Lub zog siv hluav taws xob yuav tsis tsuas yog hloov qhov hluav taws xob ntawm nws cov zis nrog kev hwm rau nws cov tswv yim, tab sis nws tseem tuaj yeem hloov kho nws qhov kev siv, kho thiab ruaj khov nws los hloov pauv los ntawm hloov pauv tam sim no rau tam sim no. Qhov ntawd yog qhov tshwm sim hauv qhov chaw ntawm PC, piv txwv li, lossis hauv lub adapter kom them lub roj teeb. Hauv cov xwm txheej no, lub CA nws yuav mus los ntawm ib txwm 50 Hz thiab 220 / 240v, mus rau DC ntawm 3.3v, 5v, 6v, 12v, thiab zoo li ...

Cov peev txheej tawm vs hloov chaw: qhov sib txawv

hloov qhov chaw

Yog koj nco txog adapters lossis charger ntawm cov xov tooj qub, lawv loj dua thiab hnyav dua. Cov no yog cov khoom siv hluav taws xob tawm, thaum niaj hnub no sib dua thiab sib zog dua yog hloov cov khoom siv fais fab. Qhov sib txawv:

  • Hauv ib kab ntawv qhov nrawm ntawm qhov hluav taws xob tam sim no tau txo los ntawm kev hloov pauv, tom qab ntawd yuav raug kho los ntawm vaj tswv. Nws kuj tseem yuav muaj lwm theem nrog cov khoom siv hluav taws xob lossis lwm yam kev ruaj khov hluav taws xob. Qhov teeb meem nrog hom kev hloov pauv no yog poob lub zog hauv daim ntawv cua sov vim yog lub tshuab hloov pauv. Ib qho ntxiv, qhov kev hloov pauv no tsis tsuas yog muaj cov hlau hnyav thiab hnyav, tab sis rau cov zis siab tam sim no lawv yuav xav tau cov tooj liab tooj liab tuab heev, yog li kuj ua rau qhov hnyav thiab loj dua.
  • lub hloov chaw Lawv siv lub hauv paus ntsiab lus zoo sib xws rau txheej txheem, tab sis nws muaj qhov sib txawv. Piv txwv li, hauv cov xwm txheej no lawv nce qhov zaus ntawm tam sim no, nce los ntawm 50 Hz (hauv Tebchaws Europe), txog 100 Khz. Qhov no txhais tau tias kev poob qis raug txo thiab qhov loj ntawm lub tshuab hloov pauv tau txo qis heev, yog li lawv yuav sib zog dua thiab cog lus ntau dua. Txhawm rau ua tau qhov no, lawv hloov AC mus rau DC, tom qab ntawd los ntawm DC rau AC nrog qhov sib txawv ntau dua li qhov pib, thiab tom qab ntawd lawv hloov pauv hais tias AC rov qab mus rau DC.

Niaj hnub no, cov khoom siv hluav taws xob tawm tau ua tiav lawv tau ploj mus, vim nws qhov hnyav thiab qhov loj. Tam sim no hloov pauv tau siv ntau dua hauv txhua yam kev thov.

Yog li ntawd, cov Cov ntsiab lus zoo nyob ntawm txoj hauv kev yooj yim ntawm kev ua haujlwm, lawv yog:

  • El qhov loj me thiab qhov hnyav ntawm cov kab tawm tuaj yeem yog qhov tseem ceeb, nrog txog 10 kg hauv qee kis. Thaum cov hloov pauv, qhov hnyav tuaj yeem tsuas yog ob peb grams.
  • Nyob rau hauv cov ntaub ntawv ntawm Cov zis hluav taws xob, cov peev txheej tawm los tswj cov zis uas siv cov hluav taws xob ntau dua los ntawm cov theem dhau los thiab tom qab ntawd tsim cov hluav taws xob qis dua ntawm lawv cov zis. Nyob rau hauv rooj plaub ntawm kev hloov pauv, lawv tuaj yeem sib npaug, qis dua, thiab txawm tias hloov pauv dua li cov ntawm cov tswv yim, ua rau nws muaj ntau yam ntxiv.
  • La kev ua haujlwm thiab kev xa tawm Nws kuj txawv, vim tias cov hloov pauv tau ua haujlwm tau zoo dua, ua kom siv lub zog zoo dua, thiab lawv tsis yaj cov cua sov ntau li, yog li lawv yuav tsis xav tau cov cua txias loj.
  • La tsis yooj yim nws yog me ntsis siab dua hauv qhov kev hloov pauv vim muaj cov lej ntau dua.
  • Linear fonts tsis tsim cuam ​​tshuam nrog feem ntau, yog li lawv zoo tshaj thaum cuam tshuam yuav tsum tsis txhob tshwm sim. Qhov hloov pauv ib qho ua haujlwm nrog ntau zaus ntau dua, thiab yog vim li cas nws thiaj li tsis zoo hauv qhov kev nkag siab no.
  • El zog zog ntawm cov peev txheej tawm tsawg, vim tias lub zog tau txais los ntawm qhov hluav taws xob siab ntawm cov kab hluav taws xob. Qhov no tsis yog qhov hloov pauv, txawm hais tias cov theem dhau los tau ntxiv los kho qhov teeb meem no mus rau qhov zoo, tshwj xeeb tshaj yog cov khoom siv muag hauv Europe.

Ua haujlwm

hloov qhov chaw

Tau qhov twg los: Avnet

Kom nkag siab zoo kev ua haujlwm ntawm kev hloov chaw, nws cov theem sib txawv yuav tsum tau txheeb raws li cov block, zoo li tuaj yeem pom hauv daim duab yav dhau los. Cov blocks no muaj lawv cov haujlwm tshwj xeeb:

  • Lim 1: nws yog lub luag haujlwm tshem tawm cov teeb meem ntawm cov khoom siv hluav taws xob, xws li suab nrov, sib haum xeeb, hloov pauv, thiab lwm yam. Txhua yam no tuaj yeem cuam tshuam nrog kev ua haujlwm ntawm cov khoom siv hluav taws xob.
  • Rectifier: nws txoj haujlwm yog txhawm rau tiv thaiv ib feem ntawm qhov teeb meem sinusoidal los ntawm kev hla, uas yog, tam sim no tsuas yog hla mus rau ib qho kev taw qhia, ua kom muaj nthwv dej hauv daim ntawv ntawm mem tes.
  • Lub zog hloov kho qhov tseeb: yog tias tam sim no tsis dhau theem nrog kev hwm rau qhov hluav taws xob, txhua lub zog ntawm lub network yuav tsis siv tau zoo, thiab tus kho qhov teeb meem no daws qhov teeb meem no.
  • Tshuab looj- Cov capacitors yuav ua rau lub teeb liab mem tes tawm los ntawm theem dhau los, khaws cia tus nqi thiab ua kom nws tawm los zoo dua, yuav luag zoo li lub teeb liab txuas mus.
  • Transistor / maub los: nws ua raws li kev tswj hwm txoj kev hla ntawm tam sim no, txiav thiab qhib txoj kev, uas hloov pauv yav dhau los yuav luag tiaj tus tam sim no rau hauv ib qho pulsating. Txhua yam yuav raug tswj los ntawm tus tswj hwm, uas tseem tuaj yeem ua lub luag haujlwm tiv thaiv.
  • Hloov pauv: txo qhov hluav taws xob ntawm nws cov tswv yim los hloov nws mus rau qhov qis dua (lossis ntau qhov qis dua) ntawm nws cov zis.
  • Diode: nws yuav hloov qhov hloov pauv tam sim no tawm ntawm lub tshuab hluav taws xob mus rau hauv pulsating tam sim no.
  • Lim 2: nws mus los ntawm pulsating tam sim no mus ntxiv hauv ib qho txuas ntxiv.
  • Optocoupler: nws yuav txuas qhov chaw tso tawm nrog rau kev tswj hwm kev tswj hwm kom raug, ib hom lus tawm tswv yim.

Hom ntawm cov khoom siv

Daim phiajcim los ntawm kev ntsuas hluav taws xob

Cov chaw hloov pauv tuaj yeem faib ua plaub yam hom siv:

  • AC input / DC tso tawm: Nws muaj cov rectifier, commutator, transformer, rectifier tso zis thiab lim. Piv txwv li, lub hwj chim ntawm lub PC.
  • AC tawm tswv yim / AC tso zis: nws tsuas yog suav nrog zaus hloov pauv thiab hloov pauv zaus. Ib qho piv txwv ntawm daim ntawv thov yuav yog lub tshuab hluav taws xob tsav.
  • DC input / AC tso zis: Nws tau paub tias yog tus nqis peev, thiab lawv tsis nquag li yav dhau los. Piv txwv li, lawv tuaj yeem pom hauv cov tshuab hluav taws xob 220v ntawm 50Hz los ntawm roj teeb.
  • DC input / DC tso tawm: nws yog qhov hloov pauv lossis qhov hloov pauv tam sim no. Piv txwv, zoo li qee lub roj teeb them nyiaj rau cov khoom siv mobile siv hauv tsheb.
