Ihhashi elihle lifanelwe isihlalo esihle! Ukuthola ngokuphelele izinzuzo zamadivayisi we-SIC, kuyadingeka futhi ukubhangqa uhlelo lokujikeleza nama-capacitors afanele. Ukusuka ekuphathweni kwe-Main Drive ezimotweni zikagesi kuya ezimweni zamandla amasha aphezulu anjenge-Photovoltaic Inverters, ama-capacito efilimu aya ngokuya eba majortem, futhi imakethe idinga ngokuphuthumayo imikhiqizo esezingeni eliphezulu.
Muva nje, iShanghai Yongming Electronic Co, Ltd yethule i-DC Support amafilimu ama-capacitors, anezinzuzo ezine ezivelele ezibenza zilungele izikhundla ze-Itrines's Seventh. Baphinde basize ekubhekaneni nezinselelo zokuqina, ukuthembeka, okuncane, kanye nezindleko ezinhlelweni zeSic.
Ama-capacitors wefilimu afinyelela cishe ama-90% ukungena kuzicelo eziphambili zokushayela. Kungani sibadinga?
Eminyakeni yamuva nje, ngokuthuthuka okusheshayo kwezimboni ezintsha zamandla njengokugcina amandla, ukushaja, nezimoto zikagesi (evs), isidingo sama-capacitors we-DC-Link Capacitor benyuka ngokushesha. Mane nje ubeke, i-DC-Link Capacitors isebenza njenge-buffers emijikelezo, edonsa imijikelezo ephezulu yokuphambuka kusuka ekupheleni kwebhasi kanye nokushintshwa kwamandla webhasi, ngaleyo ndlela ukuvikela ukushintshwa kwe-Igbt kanye ne-Sic Mostage imithelela.
Imvamisa, ama-capacitors we-aluminium electrolytic asetshenziswa kwizicelo zokusekelwa kwe-DC. Kodwa-ke, nge-voltage yebhasi yezimoto ezintsha ze-Energy ezikhulayo kusuka ku-400V kuya ku-800V nezinhlelo ze-Photovoltaic ezihambelana naku-1500V kanye ne-2000V, isidingo sama-capacitors sefilimu ukukhuphuka kakhulu.
Idatha ikhombisa ukuthi ngo-2022, umthamo ofakiwe wama-Inverters we-Electric drive asuselwa kuma-Accountion Capacitor asuselwa kumayunithi angama-DC-Link Units afinyelela amayunithi angama-5.1117 million, accounting for 88.7% wamandla athile afakiwe ama-elekthronikhi. Ukuhola okuhola izinkampani ezikhona njengamandla we-FUDI, i-Tesla, ubuchwepheshe be-insovance, i-nider, namandla e-wiran konke ukusebenzisa ama-capacitors we-DC-Link asebenzisa amandla afinyelela kuma-82.9% ahlanganisiwe afinyelela ku-82.9%. Lokhu kukhombisa ukuthi ama-capacitors efilimu athathe indawo ama-capacitors e-electrolytic njenge-mainestream emakethe ye-gercy.
Lokhu kungenxa yokuthi ukumelana kwamandla kagesi okuphezulu kwama-aluminium electrolytic capacitors cishe angama-630v. Ekusetshenzisweni kwamandla aphezulu aphezulu kanye namandla aphezulu angenhla kwe-700V, ama-capacitors amaningi we-electrolytic adinga ukuxhunywa ochungechungeni kanye nokufana nokuhlangabezana nezidingo zokwenziwa kwamandla, izindleko ze-BOM, kanye nezinkinga zokuthembela.
Iphepha lokucwaninga elivela e-University of Malaysia libonisa ukuthi ama-capacitors e-electrolytic asetshenziswa ngokujwayelekile kusixhumanisi se-DC se-silicon Igbt Half-Bridgen Inverters, kepha i-voltage surtes ingenzeka ngenxa yokumelana nama-capacitor aphezulu alinganayo. Uma kuqhathaniswa nezixazululo ze-IGBT ezisuselwa ku-IGBT, ama-SiC Mosfets anezikhathi eziphakeme zokushintsha, okuholela ekuphakameni kwamandla aphezulu we-voltage surge amplitude ekuxhumanisaneni kwe-DC ye-Half-Bridy Amptervers. Lokhu kungaholela ekunciphiseni kokusebenza kwedivaysi noma kulimaze, njengoba imvamisa yesivumelwano sama-capacitos we-electrolytic kuphela ama-4KHZ kuphela, anganele ukudonsa i-ripp yamanje ye-mosfet ye-mosfet.
Ngakho-ke, kuzinhlelo zokusebenza ze-DC ezinezidingo eziphakeme zokwethenjwa, ezinjengabasezingeni eliphakeme bokushayela kanye nabakwa-Photovoltaic, ama-capacitors wefilimu akhethiwe. Uma kuqhathaniswa nama-capacitors we-electrolytic we-aluminium, izinzuzo ezisebenzayo zifaka ukumelana namandla aphezulu, i-ESR ephansi, alikho i-polarity, ukusebenza okuzinzile, kanye nokuphila okuthe xaxa, okunika amandla i-design ethembekile yohlelo ngokumelana namandla anamandla.
Ngokwengeziwe, ukusebenzisa ama-capacitor amafilimu ohlelweni kungaphindaphinda kaningi, izinzuzo eziphansi zezinzuzo ze-SIC Mosfets, zinciphisa kakhulu usayizi kanye nesisindo sezinto ezingenamikhawulo (i-inductor, ama-transformers, ama-capacitors) ohlelweni. Ngokusho kocwaningo lwe-WolfSpeed, i-Igbt ye-IGBT esekelwe kwi-IGBT ye-10KW idinga ama-capacitors angama-22 we-Aluminium Electrolytic, kanti i-40kw Sic Inverter idinga kuphela ama-capacitors wefilimu ayi-8, ukunciphisa kakhulu indawo ye-PCB.
I-YMIN iqala ama-capacitor amasha wefilimu anezinzuzo ezine ezinkulu ukusekela imboni yamandla entsha
Ukuze ubheke izicelo eziphuthumayo zemakethe, ymin usanda kuvula i-MDP ne-MDR Security ye-DC Support Ama-Capacitors. Sisebenzisa izinqubo zokukhiqiza ezithuthukile nezinto ezisezingeni eliphakeme, la ma-capacitors ahambisana ngokuphelele nezidingo zokusebenza ze-SiC Mosfets kanye nama-Igttors asuselwa ku-silicon avela kubaholi be-miconductor emhlabeni jikelele.
Ama-capacitors we-ymin's MDP kanye ne-MDP kanye ne-MDP ama-capacitors anezici ezimbalwa eziphawuleka: Ukumelana okulinganiselayo okulinganayo (ESR), i-voltage ephakeme ephakeme, ukuvuza okuphansi okukhona, nokuzinza okushisa okuphezulu.
Okokuqala, ama-capacitors wefilimu ka-Ymin afaka umklamo ophansi we-ESR, ngokunciphisa ngokucophelela ukucindezelwa kwe-voltage ngesikhathi sokushintshwa kwama-mostets ama-sic kanye nama-sigbt ase-siil, ngaleyo ndlela anciphise ukulahleka kohlelo lwe-capacitor kanye nokwenza ngcono ukusebenza kahle kohlelo. Ngokwengeziwe, la ma-capacitors ane-voltage ephakeme kakhulu, ekwazi ukubekezelela izimo eziphakeme ze-voltage kanye nokuqinisekisa ukusebenza kohlelo ezinzile.
Uchungechunge lwe-MDP ne-MDR ye-YMIN film capacitors luhlinzeka ngamanani amabanga angu-5Uf-150UF no-50000uf-3000uf-3000uf, kanye nama-voltage amabanga angu-350v-1500V kanye ne-350v-2200V, ngokulandelana.
Okwesibili, ama-capacitors amafilimu wakamuva we-YMIN ane-ukuvuza ephansi yamanje nokuqina okuphezulu kokushisa. Endabeni kagesi yokulawula izimoto zikagesi, okuvame ukuba namandla aphezulu, isizukulwane sokushisa esiphumela singathinta kakhulu isikhathi sokuphila kanye nokwethenjwa kwama-capacitors wefilimu. Ukubhekana nalokhu, uchungechunge lwe-MDP ne-MDR kusuka ku-YMin Kufaka izinto ezisezingeni eliphakeme nezindlela zokukhiqiza ezithuthukile ukuklama isakhiwo esithuthukisiwe se-capacitors. Lokhu kuqinisekisa ukusebenza okuzinzile ngisho nasezindaweni ezisezingeni eliphakeme kakhulu, ukuvimbela ukonakala kwenani le-capacitor noma ukwehluleka ngenxa yokunyuka kwezinga lokushisa. Ngaphezu kwalokho, la ma-capacitors anokuphila okude isikhathi eside, anikeze ukwesekwa okuthembekile kwamandla we-elektroniki kagesi.
Okwesithathu, ama-capacitors e-MDP kanye ne-MDP ne-MDR avela ku-YMin afaka usayizi omncane kanye nobuningi bamandla aphezulu. Isibonelo, kuzinhlelo ezingama-800V ezisebenza ngogesi, umkhuba ukusebenzisa amadivaysi e-SIC ukunciphisa usayizi wama-capacitors nezinye izinto ezingenamikhawulo, ngaleyo ndlela kuthuthukiswe ama-miniaturion of electronic. I-YMIN isebenzise ubuchwepheshe obusha befilimu yefilimu, engagcini nje ngokukhulisa ukuhlanganiswa kohlelo lonke kanye nokusebenza kahle kepha futhi inciphisa usayizi wesistimu nesisindo, ukuthuthukisa ukusebenziseka nokuguquguquka kwamadivayisi.
Uchungechunge oluphelele lwe-DC-Link Film Capacitor lunikeza ngcono ukuthuthuka kwama-30% ku-DV / DT ehambisa amandla namandla okuphila ngokuphila ngokuqhathaniswa namanye ama-capacitors wefilimu emakethe. Lokhu akupheleli ukuthembeka okungcono kwe-SIC / IGBT Circuits kodwa futhi kunikeza ukusebenza kwezindleko ezingcono, ukunqoba izithiyo zamanani kuhlelo lokusebenza olusakazekile lwama-capacitors wefilimu.
Njengoba iphayona lemboni, i-Ymin ibambe iqhaza kakhulu ensimini yeCapacitor iminyaka engaphezu kwengu-20. Ama-capacitor awo aphezulu avele asetshenziswe kahle emasimini aphezulu afana ne-OBC Obc, ama-Photovoltaic ama-inverters, namarobhothi ezimboni iminyaka eminingi. Lesi sizukulwane esisha semikhiqizo ye-capacitor yefilimu sixazulula izinselelo ezahlukahlukene ekulawulweni kwenqubo yokukhiqiza yefilimu capacitor control kanye nemishini, siqede isitifiketi sokuthembela ngamabhizinisi omhlaba aholayo, futhi athole ukuthembeka komkhiqizo kumakhasimende amakhulu. Ngokuzayo, i-Ymin izothuthukisa ukunqwabelana kwayo kwesikhathi eside ukusekela ukuthuthukiswa okusheshayo komkhakha wamandla omusha ngokuthembela okuphezulu kanye nemikhiqizo ye-capacitor ebiza kakhulu.
Ngeminye imininingwane, sicela uvakashelewww.ymin.cn.
