Hatchi yabwino ndiyoyenera kukhala ndi chishalo chabwino! Kuti mumvetse bwino za zida za SIC, ndikofunikiranso kuwirikiza dongosolo la madera ndi ma cartactors abwino. Kuchokera pamayendedwe akulu pamagalimoto pamagetsi okwera kwambiri monga mawonekedwe apamwamba kwambiri ozungulira ngati chithunzi
Posachedwa, Shanghai Yongming Entractonic Co. Amathandizanso kuthana ndi zovuta zokhazikika, kudalirika, kakang'ono, ndi mtengo mu stic systems.
Makanema a filimu amakwaniritsa pafupifupi 90% kuloweza pamagalimoto a Mage. Chifukwa chiyani SIC ndi IGBT imawafuna?
M'zaka zaposachedwa, ndikukula kwamphamvu kwa makompyuta atsopano monga kusungidwa kwa mphamvu, kulipira, komanso magalimoto amagetsi (evs), kufunikira kwa calactitors DC kwachulukirachulukira. Mwachidule, ma carpoctitors a DC-Lumikizani amakhala ngati mabwalo a mabwalo a mabasi ndikutha kwa mabasi a mabasi, motero amateteza ma stage a mafunde am'mapapo ndi magetsi otsika.
Nthawi zambiri, ma car Cavactor a aluminiyal amagwiritsidwa ntchito mu pulogalamu ya DC. Komabe, magetsi a basi yamphamvu yamagetsi yatsopano yowonjezereka kuchokera pa 400V mpaka 800V ndi 300V ndi 300V ndi 2000V, zomwe akatswiri ogwiritsa ntchito mafilimu amakwera kwambiri.
Zambiri zikuwonetsa kuti mu 2022, mphamvu yokhazikitsidwa yamagetsi yamagetsi yolumikizirana ndi mafilimu a DC Kutsogolera makampani amagetsi monga mphamvu ya fidi, tesla, ukadaulo, nidec, ndi wojambula wa Winning Propever ma traclers, ndi chiwerengero chophatikizika cha 82.9%. Izi zikuwonetsa kuti capoctors filimu yasinthanitsa ma electrolytic monga chinsinsi cha msika wamagetsi.
Izi ndichifukwa choti mphamvu yamagetsi yayikulu kukana kwa aluminium ma electrolytic ndi pafupifupi 630v. M'magetsi apamwamba komanso mphamvu zogwiritsira ntchito pamwamba pa 700V, ma carvactors angapo a electrolytic amafunika kulumikizidwa mu mndandanda komanso wofanana kuti akwaniritse zofunika kugwiritsidwa ntchito, zomwe zimabweretsa zowonjezera zowonjezera, mtengo wotsika mtengo, komanso nkhani zodalirika.
Pepala lofufuzira kuchokera ku Yunivesity of Malaysia limawonetsa kuti makatoni a electrolytic amagwiritsidwa ntchito mu ulalo wa DC Poyerekeza ndi nthiti ya Silicon, SICS osics ali ndi ma pafupipafupi osintha kwambiri, zomwe zimapangitsa kuwongolera mphamvu kwambiri mu dc kulumikizana kwa olumikizana ndi BRIGH Briber. Izi zitha kubweretsa kuwonongeka kwa chipangizo kapena kuwonongeka kwa ma capactortic a ma electrolytic ndi 4kHz, osakwanira kuyamwa komwe kumayenderana ndi zovuta za SICS.
Chifukwa chake, mu mafomu a DC omwe ali ndi zofunikira kwambiri, monga magetsi oyenda pamagetsi ndi chithunzi cha zithunzi ndi chithunzi. Poyerekeza ndi ma car Cavactors a Allaminic, maubwino awo amagwiritsa ntchito mphamvu zapamwamba, ESR, palibe polated, okhazikika, komanso njira yayitali yodalirika yolimba.
Kuphatikiza apo, kugwiritsa ntchito ma carluctors filganictors mu dongosololi kungaphunzitse mobwerezabwereza, maubwino otsika kwambiri a sctetes, kuchepetsera kukula ndi kulemera kwa zigawo zikuluzikulu (maapopoctor) m'dongosolo. Malinga ndi kafukufuku wa Wolfspeeed, yemwe anali ndi vuto la 10kW lilibettic amafunika 22 ma aluminiyal a aluminiyal, pomwe wolamulira wa 40kw wachifaniziro amangofunika 8 mafilimu, amachepetsa dera la PCB.
YMM imayambira makanema atsopano a kanema wokhala ndi zabwino zinayi zothandizira makampani atsopano
Kuti athe kuthana ndi zofuna zamisika, Ymin yafika posachedwa pa MDP ndi MDR mndandanda wa makanema a DC. Kugwiritsa ntchito njira zapamwamba kwambiri komanso zida zapamwamba kwambiri, ma capuctors awa ndiogwirizana bwino ndi zofunikira za ntchito za SICS mostecs ndi atsogoleri a silika padziko lonse lapansi monga infonducton.
JMM's MDP ndi MDR mndandanda wa ma carditors ali ndi zinthu zingapo zowoneka bwino: mndandanda wofanana (esr), magetsi apamwamba kwambiri, ndi kutentha kwambiri.
Choyamba, makanema ojambula a YMM amakhala ndi kapangidwe kotsika kwambiri, moyenera kuchepetsa nkhawa za magetsi pakusintha kwa SICS masic masic ndi igbts okhazikika a silicon, potero kuchepetsa kutaya kwapamwamba ndikuwongolera dongosolo lonse. Kuphatikiza apo, magetsi awa ali ndi magetsi okwera kwambiri, okhoza kukhala apamwamba kwambiri komanso kuwonetsetsa kuti akonzekere dongosolo lokhazikika.
MDP ndi MDR mndandanda wa ymini films imapereka ma carpocs a 5UF-15fuf-3uf-3000Uf, 1550v-1550v-22hiv-2250, 2200V, 2200V, motsatana.
Kachiwiri, makanema aposachedwa a ymin ali ndi chotsika chotsika ndi kutentha kwapamwamba komanso kwapamwamba kwambiri. Pankhani ya galimoto yamagetsi yamagetsi yamagetsi, yomwe imakhala ndi mphamvu yayikulu, mbadwo wakutentha umatha kukhudza moyo ndi kudalirika kwa capoctors. Kuti muthene ndi izi, MDP ndi MDR mndandanda wa ymin imagwiritsa ntchito zida zapamwamba komanso njira zopangira zapamwamba zopangira maofesi. Izi zimathandizanso kugwira ntchito mokhazikika ngakhale m'malo otentha kwambiri, kuteteza capactotion kuwonongeka kapena kulephera chifukwa cha kutentha. Kuphatikiza apo, maapositi awa ali ndi moyo wautali, ndikuthandizira kuthandizira kodalirika kwa magetsi apadera.
Chachitatu, mdp ndi MDR Prinessors kuchokera ku Ymic Schoaling Squamer Squamer Squamer And Maulamuliro Wapamwamba. Mwachitsanzo, mu 800V yamagetsi yamagetsi yamagetsi, zomwe zimachitika kuti mugwiritse ntchito zida zochepetsera kukula kwa capoctor ndi zina zongokhalira, zomwe zimapangitsa kuti miniaturization yamagetsi yamagetsi. YEMM yagwiritsa ntchito ukadaulo wopanga makanema atsopano, omwe samangowonjezera dongosolo lonse la dongosolo ndikuchepetsa mphamvu ndi kulemera kwake, kulimbitsa thupi komanso kusinthasintha kwa zida.
Pafupifupi, ymin's mafilimu a DC-Link imapereka kusintha kwa 30% mu DV / DT kuthana ndi kuthekera komanso kuwonjezeka kwa 30% poyerekeza ndi ma carluctors ena a filimu pamsika. Izi sizimangopereka kudalirika kwabwino kwa madera a sic / igbt koma imapereka ndalama zambiri, zomwe zikugonjetsera mitengo yamtengo wapatali yomwe ikugwiritsidwa ntchito pogwiritsa ntchito ma carfactor.
Monga mpainiya akatswiri, ymin yakhudzidwa kwambiri kumunda wa Caractor kwa zaka zopitilira 20. Ma cancacitor ake okwera kwambiri agwiritsidwa ntchito m'minda yayitali monga osweka Obc, mphamvu yatsopano yakulipiritsa, zithunzi zotsekereza, ndi maloboti osungira mafakitale kwa zaka zambiri. Mbadwo watsopanowu wa katswiri wa filimuyi amathetsa zovuta zosiyanasiyana kupanga makina opanga mafilimu ndi zida, ndipo adakwaniritsa ntchito yayikulu, ndikuwonetsa kudalirika kwa makasitomala akuluakulu. M'tsogolomu, ymin ipeza kuchuluka kwake kwaukadaulo kuti muthandizire kukula kwa makampani atsopano a mphamvu zamagetsi omwe ali ndi vuto lalikulu komanso lokwera mtengo.
Kuti mumve zambiri, chonde pitaniwww.ymin.cn.
