Msika wamsika wama module amphamvu!

Msika wa msika wama modules amphamvu!

M'zaka zaposachedwa, ndi chitukuko chofulumira cha teknoloji yamagetsi yamagetsi, mgwirizano pakati pa zipangizo zamagetsi zamagetsi ndi ntchito ya anthu ndi moyo wakhala ukuyandikira kwambiri, ndipo zipangizo zamagetsi sizimasiyanitsidwa ndi magetsi odalirika.M'zaka za m'ma 1980, magetsi apakompyuta anazindikira modularization ya kusintha kwa magetsi., adatsogola pakumalizitsa kulowetsedwa kwa magetsi apakompyuta.M'zaka za m'ma 1990, magetsi osinthika adalowa m'madera osiyanasiyana a zipangizo zamagetsi ndi zamagetsi.Ma switch oyendetsedwa ndi pulogalamu, kulumikizana, zida zamagetsi zamagetsi zamagetsi, ndi zida zowongolera zida zakhala zikugwiritsidwa ntchito kwambiri.Kusintha magetsi kwalimbikitsa kusintha kwamagetsi Kukula mwachangu kwaukadaulo.Tsopano, kugwiritsa ntchito mwanzeru m'magawo omwe akutulukapo monga digito TV, LED, IT, chitetezo, njanji yothamanga kwambiri, ndi mafakitale anzeru zilimbikitsanso kukula kwa msika wosinthira magetsi.

Kusinthagawo lamagetsi ndi m'badwo watsopano wa kusintha magetsi katundu katundu, makamaka ntchito m'madera ambiri monga boma, mafakitale ndi asilikali, kuphatikizapo kusintha zipangizo, zipangizo mwayi, kulankhulana m'manja, mayikirowevu kulankhulana, kufala kuwala, routers ndi minda ina kulankhulana komanso magetsi magalimoto, zamlengalenga Dikirani.Chifukwa cha mawonekedwe a mawonekedwe afupikitsa, kudalirika kwakukulu komanso kusinthika kwadongosolo kosavuta, kugwiritsa ntchito ma modules kuti apange dongosolo lamagetsi kwapangitsa kuti ntchito yamagetsi ikhale yowonjezereka.Makamaka m'zaka zaposachedwa, chifukwa cha chitukuko chofulumira cha mautumiki a deta ndi kulimbikitsa kosalekeza kwa machitidwe ogawa magetsi, kukula kwa gawo la magetsi kwadutsa kuposa magetsi oyambirira.

Anthu ena m'makampaniwa amakhulupirira kuti kuchuluka kwamagetsi osinthira magetsi ndikomwe akuwongolera.Chitukukocho chikupita patsogolo, ndi kukula kwa chiwerengero cha manambala oposa awiri chaka chilichonse, kutsata njira yopepuka, yaying'ono, yopyapyala, phokoso lochepa, kudalirika kwakukulu ndi kusokoneza.

Kusintha ma module opangira magetsi kumatha kugawidwa m'magulu awiri: AC / DC ndi DC / DC.The DC/DC converter tsopano wakhala modularized, ndi luso mapangidwe ndi kupanga ndondomeko zakhala okhwima ndi yofanana kunyumba ndi kunja, ndipo akhala akudziwika ndi ogwiritsa.Komabe, ma modularization a AC/DC, chifukwa cha mawonekedwe ake, amakumana ndi zovuta zaukadaulo komanso zovuta kupanga popanga modularization.Kuonjezera apo, chitukuko ndi kugwiritsa ntchito magetsi osinthika ndizofunika kwambiri pakupulumutsa mphamvu, kupulumutsa chuma ndi kuteteza chilengedwe.

1. Kuchulukana kwamphamvu sikuli kokwezeka kwambiri, kokha kokwera

Pogwiritsa ntchito kwambiri ukadaulo wa semiconductor, ukadaulo wolongedza komanso kusintha kofewa kwapang'onopang'ono, mphamvu yamagetsi yamagetsi yamagetsi ikukulirakulira, kusinthika kwachangu kukukulirakulira, ndipo kugwiritsa ntchito kumakhala kosavuta komanso kosavuta.Kutembenuka kwatsopano ndi ukadaulo wapakatikati kumapangitsa kuti kachulukidwe wamagetsi azitha kupitilira (50W / cm3), kupitilira kuwirikiza kachulukidwe kamagetsi amtundu wamba, ndipo magwiridwe ake amatha kupitilira 90%.Kuchita bwino kwambiri, komwe kumakhala ndi mphamvu zochulukirapo 4x kuposa zosinthira zofananira zomwe zikupezeka pamsika, zimathandizira magwiridwe antchito a HVDC ogawa magetsi pamagwiritsidwe ntchito monga ma data center, matelefoni ndi mafakitale.

2. Low voltage ndi mkulu panopa

Ndi kuchepa kwa voteji yogwira ntchito ya microprocessor, mphamvu yotulutsa mphamvu ya gawoli yatsikanso kuchokera pa 5V yapitayi kupita ku 3.3V kapena 1.8V.Makampaniwa amalosera kuti mphamvu yotulutsa mphamvu yamagetsi idzatsikanso pansi pa 1.0V.Pa nthawi yomweyo, panopa chofunika ndi Integrated dera akuwonjezeka, amafuna kuti magetsi kupereka lalikulu katundu linanena bungwe mphamvu.Kwa magetsi a 1V / 100A module, katundu wogwira mtima ndi wofanana ndi 0.01, ndipo zamakono zamakono zimakhala zovuta kukwaniritsa zofunikira zapangidwe.Pankhani ya katundu wa 10m, kukana kwa mita kulikonse panjira yopita kumalo kudzachepetsa mphamvu ndi 10, ndi kukana kwa waya kwa bolodi losindikizidwa, kukana kwa inductor, kukana kwa MOSFET ndi kufa. mawaya a MOSFET, etc. ali ndi chikoka.

Chachitatu, ukadaulo wowongolera digito umagwiritsidwa ntchito kwambiri

Njira yosinthira magetsi imagwiritsa ntchito ukadaulo wa digito (DSC) kuwongolera mayankho otsekeka amagetsi, ndikupanga mawonekedwe olumikizirana a digito ndi dziko lakunja.Kuphatikizika kwamagetsi kogwiritsa ntchito ukadaulo wowongolera digito ndi njira yatsopano yakutsogolo kwamakampani opanga magetsi, ndipo pali zinthu zochepa pakadali pano., Makampani ambiri opangira mphamvu zamagetsi samadziwa luso lamagetsi loyendetsedwa ndi digito.Ogwira ntchito m'mafakitale amakhulupirira kuti m'mapulogalamu ambiri, kufunikira kokweza mphamvu zamagetsi kudzayendetsa kufunikira kwa ma IC oyang'anira mphamvu mchaka chamawa.Pambuyo pazaka zingapo zakukula pang'onopang'ono, kasamalidwe ka magetsi a digito tsopano alowa mu gawo lachitukuko chofulumira.Pazaka 10 zikubwerazi, kafukufuku wokhazikika pa zinthu zogwiritsa ntchito mphamvu zamagetsi akuyembekezeka kuyendetsa kukhazikitsidwa kwa kasamalidwe kamagetsi a digito pamagwiritsidwe ntchito ngati osinthira a DC-DC.

Chachinayi, gawo lamphamvu lanzeru limayamba kutentha

Mphamvu yamagetsi yanzeru sikuti imangogwirizanitsa chipangizo chosinthira mphamvu ndi dera loyendetsa galimoto pamodzi.Ilinso ndi mabwalo ozindikira zolakwika monga kuchulukira, overcurrent ndi kutenthedwa, ndipo imatha kutumiza zidziwitso ku CPU.Zimapangidwa ndi kufa kothamanga kwambiri komanso kotsika mphamvu, chowongolera cholowera pachipata komanso chitetezo chachangu.Ngakhale zitachitika ngozi ya katundu kapena kugwiritsidwa ntchito molakwika, IPM yokhayo ikhoza kutsimikiziridwa kuti siiwonongeka.Ma IPM nthawi zambiri amagwiritsa ntchito ma IGBT ngati zinthu zosinthira mphamvu, ndipo amakhala ndi zida zophatikizika zokhala ndi masensa apano komanso mabwalo oyendetsa.IPM ikupambana misika yochulukirachulukira ndi kudalirika kwake komanso kugwiritsa ntchito mosavuta, makamaka koyenera ma frequency converter ndi magetsi osinthira osiyanasiyana oyendetsa ma mota.Chida chabwino kwambiri chamagetsi chamagetsi.

Kusintha ma module opangira magetsi kukupitiliza kupititsa patsogolo kuphatikizika ndi luntha, ndipo makampaniwo akuthamangiranso kuti apereke ma CD apamwamba kwambiri, ndipo ma module anzeru apezanso chitukuko chachikulu.Ngakhale msika wosinthira magetsi uli ndi chiyembekezo chowoneka bwino, msika wapamwamba kwambiri pakadali pano ukulamulidwa ndi mitundu yapadziko lonse lapansi.Ma brand amderali akuyenera kupitiliza kulimbikitsa kamangidwe kazinthu, kuwongolera zabwino, ndi kudalirika kuti athetse msika waukuluwu.
