Kusintha kochokera: ndi chiyani, kusiyana ndi mzere, ndi chiyani?

kusinthidwa gwero

Una kusinthidwa gwero ndi chida chamagetsi chokhoza kusintha mphamvu zamagetsi kudzera mndandanda wa zigawo zamagetsi, monga ma transistors, ma voltage regulator, ndi zina zambiri. Ndiye kuti, ndi magetsi, koma ndizosiyana ndi zomwe zidafanana. Magwero awa amadziwikanso kuti SMPS (switch mode Power Supply), ndipo amagwiritsidwa ntchito pano pazambiri ...

Kodi magetsi ndi chiyani

Gwero la ATX

Una magetsi, kapena PSU (Power Supply Unit), ndi chida chomwe chimagwiritsidwa ntchito popereka magetsi moyenera kuzinthu zosiyanasiyana kapena makina. Cholinga chake ndikulandila mphamvu kuchokera pamagetsi yamagetsi ndikuisintha kukhala yamagetsi oyenera komanso apano kuti zinthu zolumikizidwa zizigwira bwino ntchito.

Mphamvu yamagetsi sidzangosintha mphamvu yazotulutsa zake malinga ndi kulowetsa kwake, komanso imatha kusintha mphamvu yake, konza ndi kukhazikika kuti musinthe kuchokera pakali pano kupita pakadali pano. Izi ndizomwe zimachitika pagwero la PC, mwachitsanzo, kapena mu adapter yolipiritsa batri. Zikatero, CA idzachoka pa 50 Hz ndi 220 / 240v, kupita ku DC pa 3.3v, 5v, 6v, 12v, ndi zina zotero ...

Zowonjezera vs magwero osintha: kusiyana

Ngati mukukumbukira ma adap kapena ma charger mwa matelefoni akale, anali okulirapo komanso olemera. Awo anali magetsi amagetsi, pomwe opepuka amakono komanso ophatikizika amasintha magetsi. Kusiyana:

  • Mu mzere wofanana Mphamvu yamagetsi imachepetsedwa pogwiritsa ntchito thiransifoma, kuti ikonzedwe kenako ndi milungu. Idzakhalanso ndi gawo lina lokhala ndi ma electrolytic capacitors kapena othandizira ma voltage. Vuto ndi mtundu uwu wa chosinthira ndikutaya mphamvu kwamtundu wa kutentha chifukwa chosinthira. Kuphatikiza apo, chosinthira ichi sichimangokhala chachitsulo cholemera komanso chachikulu, koma pamagetsi otulutsa kwambiri adzafunika waya wokulirapo kwambiri wamkuwa, ndikupitilizanso kulemera ndi kukula kwake.
  • ndi anasintha magwero Amagwiritsanso ntchito mfundo yomweyi pochita izi, koma imakhala ndi kusiyana. Mwachitsanzo, panthawiyi amachulukitsa pafupipafupi, kuyambira 50 Hz (ku Europe), mpaka 100 Khz. Izi zikutanthauza kuti zotayika zimachepetsedwa ndipo kukula kwa thiransifoma kumachepa kwambiri, chifukwa chake azikhala opepuka komanso ophatikizika. Kuti izi zitheke, amasintha AC kukhala DC, kenako kuchokera ku DC kupita ku AC mosiyanasiyana mosiyana ndi koyambirira, kenako amasintha AC kubwerera ku DC.

Masiku ano, magetsi ophatikizika ali pafupifupi iwo asowa, chifukwa cha kulemera kwake ndi kukula kwake. Zosintha tsopano zikugwiritsidwa ntchito koposa mitundu yonse yazofunsira.

Chifukwa chake, a mfundo zazikulu kutengera njira yoyambira yogwirira ntchito, ndi awa:

  • El kukula ndi kulemera Zina zazingwe zingakhale zofunikira, mpaka 10 kg nthawi zina. Pomwe zidasintha, kulemera kwake kungangokhala magalamu ochepa.
  • Pankhani ya Linanena bungwe voteji, Zowonjezera zowongolera zimawongolera zomwe zatulutsidwa pogwiritsa ntchito voltages yayikulu kuyambira magawo am'mbuyomo kenako ndikupanga zotsika zochepa pazomwe akutulutsa. Pankhani yosinthira, atha kukhala ofanana, otsika, komanso osandulika kuposa omwe amathandizira, kuwapangitsa kukhala osunthika.
  • La Kuchita bwino ndi kutaya Zimasiyananso, popeza zomwe zasinthidwa ndizothandiza kwambiri, zimagwiritsa ntchito bwino mphamvu, ndipo sizimatha kutentha kochuluka, chifukwa chake sizidzafunika makina ozizira oterewa.
  • La zovuta ndiyokwera pang'ono pakusintha chifukwa cha magawo ambiri.
  • Zolemba zazitali sizimapanga kusokoneza Nthawi zambiri, zimakhala bwino ngati zosokoneza siziyenera kuchitika. Yosintha imagwira ntchito ndimafupipafupi, ndichifukwa chake siyabwino kwenikweni.
  • El mphamvu yamagetsi chifukwa magwero ofanana ndi otsika, chifukwa mphamvu imachokera pazitunda zamagetsi pamzere wamagetsi. Izi sizomwe zimachitika posintha, ngakhale magawo am'mbuyomu adawonjezeredwa kuti athetse vutoli kwakukulu, makamaka pazida zomwe zimagulitsidwa ku Europe.

Kuti mumvetse bwino magwiridwe antchito osinthira, magawo ake osiyanasiyana amayenera kukonzedwa ngati midadada, monga tingawonere m'chithunzichi. Mabuloguwa ali ndi ntchito yawo:

  • Sefani 1: Ili ndi udindo wothetsa mavuto amagetsi, monga phokoso, ma harmoniki, ma transients, ndi zina zambiri. Zonsezi zimatha kusokoneza kagwiritsidwe kazinthu zamagetsi.
  • Wokonza: ntchito yake ndikuletsa gawo la chizindikiro cha sinusoidal kuti lisadutse, ndiye kuti pakadali pano limangodutsa mbali imodzi, ndikupanga funde la mawonekedwe.
  • Wothandizira mphamvu: ngati pakadali pano gawo lake silikugwirizana ndi magetsi, mphamvu zonse za netiweki sizigwiritsidwa ntchito bwino, ndipo wowongolera uyu athetsa vutoli.
  • Condenser- Ma capacitors amachepetsa chizindikiritso chotuluka m'mbuyomu, ndikusunga chindapusa ndikupangitsa kuti chikhale chosangalatsa, pafupifupi ngati siginecha yopitilira.
  • Transistor / Mtsogoleri: imakhala ngati chiwongolero chadongosolo lamakono, kudula ndi kuyendetsa gawolo, lomwe limasintha nyengo yapitayi kuti ikhale yopanda pake. Chilichonse chizilamuliridwa ndi wowongolera, yemwe amathanso kukhala ngati chitetezo.
  • Kusintha: amachepetsa mphamvu yamagetsi pamagetsi ake kuti igwirizane ndi mphamvu yamagetsi yotsika (kapena ma voltages angapo) atatulutsa.
  • Zosintha: idzasintha zinthu zomwe zikusintha kuchokera ku thiransifoma kukhala zam'mapapo.
  • Sefani 2: imachoka pakukweza mpaka pano mopitilira muyeso.
  • Optocoupler: idzagwirizanitsa zomwe zimachokera ndi dera loyendetsa kuti likhale lolondola, mtundu wa mayankho.

Mitundu yazambiri

Chizindikiro kuchokera pamagetsi

Zosintha zitha kugawidwa m'magulu anayi mitundu pachimake:

  • AC athandizira / DC linanena bungwe: Amakhala ndi rectifier, commutator, thiransifoma, zotulutsa zowongolera komanso zosefera. Mwachitsanzo, magetsi a PC.
  • AC athandizira / AC linanena bungwe: imangokhala ndi chosinthira pafupipafupi komanso chosinthira pafupipafupi. Chitsanzo cha kugwiritsa ntchito chingakhale kuyendetsa kwamagetsi.
  • Kuyika kwa DC / kutulutsa kwa AC: Amadziwika kuti amagulitsa ndalama, ndipo samakhala pafupipafupi monga am'mbuyomu. Mwachitsanzo, amapezeka mumagetsi a 220v pa 50Hz kuchokera pa batri.
  • DC athandizira / DC linanena bungwe: ndi voliyumu kapena chosinthira chamakono. Mwachitsanzo, ngati ma charger ama batri azida zamagetsi zomwe zimagwiritsidwa ntchito mgalimoto.

Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
