Ndi kukhwima pang'onopang'ono kwa ukadaulo wa gallium nitride (GaN), chiwerengero chowonjezeka cha ma converter a AC/DC akugwiritsa ntchito GaN ngati zinthu zosinthira kuti zilowe m'malo mwa zigawo zachikhalidwe za silicon. Pakugwiritsa ntchito ukadaulo watsopanowu, ma capacitor oyendetsera magetsi nawonso amachita gawo lofunikira.
YMIN yakhala ikudzipereka kwa nthawi yayitali pakupanga ma capacitor oyendetsera magetsi kuti agwiritsidwe ntchito mu ma converter a AC/DC ochokera ku GaN ndipo yapeza ntchito zopambana m'mafakitale osiyanasiyana, monga kuyitanitsa mwachangu (kuchokera ku IQ fast charging yakale, PD2.0, PD3.0, PD3.1), ma adapter a laputopu, kuyitanitsa mwachangu njinga zamagetsi, ma onboard charger (OBC)/DC fast charging piles, ma server power supplies, ndi zina zambiri. Ma capacitor atsopanowa amatha kukwaniritsa bwino makhalidwe abwino a GaN, akuchita bwino kwambiri pazochitika zogwiritsira ntchito komanso kukwaniritsa zosowa za makasitomala kuti akonze magwiridwe antchito komanso kukweza mobwerezabwereza. Pansipa, tifotokoza mwatsatanetsatane makhalidwe awo ogwiritsira ntchito.
01 GaN imathandiza kuchepetsa ma converter a AC/DC
Ma circuit ambiri amagwiritsa ntchito magetsi a DC m'malo mwa magetsi a AC, ndipo ma AC/DC converters ndi ofunikira ngati zipangizo zomwe zimasintha magetsi a AC amalonda omwe amaperekedwa m'nyumba ndi m'mabizinesi kukhala magetsi a DC. Ngati magetsi ali ofanana, chizolowezi chimakhala kuchepetsa ma converters poganizira za kusunga malo ndi kusunthika.
Kugwiritsa ntchito GaN (gallium nitride) kwapita patsogolo kwambiri pakupanga ma converter a AC/DC kukhala ochepa. Poyerekeza ndi zigawo zachikhalidwe za Si (silicon), ubwino wa GaN ndi kutayika kochepa kwa switching, kugwira ntchito bwino kwambiri, kuthamanga kwa ma elekitironi ambiri komanso mphamvu zoyendetsera magetsi. Izi zimathandiza kuti AC/DC converter izilamulira bwino ntchito zosinthira magetsi, zomwe zimapangitsa kuti mphamvu zisinthe bwino.
Kuphatikiza apo, ma frequency osinthasintha kwambiri amatha kusankhidwa, zomwe zimalola kugwiritsa ntchito zigawo zazing'ono zopanda ntchito. Izi zili choncho chifukwa GaN imatha kusunga magwiridwe antchito apamwamba ngakhale pakusintha kwa ma frequency apamwamba, mofanana ndi kusintha kwa ma frequency otsika a Si.
02 Udindo wofunika wama capacitor oyendetsera
Pakupanga ma converter a AC/DC, ma capacitor otulutsa ndi ofunikira kwambiri. Ma capacitor oyendetsera magetsi angathandize kuchepetsa kugwedezeka kwa mphamvu yotulutsa ndipo amagwira ntchito yofunika kwambiri pakusefa m'mabwalo osinthira amphamvu kwambiri. Pamene capacitor imatenga mphamvu yogwedezeka, mosakayikira imapanga mphamvu yogwedezeka. Pakugwiritsa ntchito, nthawi zambiri pamafunika kuti mphamvu yogwirira ntchito isapitirire 1% ya mphamvu yogwirira ntchito ya zida.
Ngati GaN ikugwiritsidwa ntchito, ESR ya YMIN solid-liquid hybrid capacitors imakhala yokhazikika pa 10KHz ~ 800KHz, yomwe ingakwaniritse zofunikira za kusintha kwa GAN kwapamwamba.
Chifukwa chake, mu ma converter a AC/DC omwe amagwiritsa ntchito gallium nitride, ma capacitor oyendetsera magetsi amakhala ma capacitor abwino kwambiri otulutsa mphamvu.
03 YMIN yofanana ndi capacitor yoyendetsera bwino
Pogwiritsa ntchito GaN, kugwiritsa ntchito ma AC/DC converters osinthasintha pafupipafupi kwawonjezeka pang'onopang'ono. Pofuna kupitiliza kukwaniritsa zosowa za makasitomala, YMIN, monga katswiri woyambitsa msika wa ma capacitor oyendetsera magetsi, imagwiritsa ntchito ukadaulo wake wapamwamba kwambiri wochita bwino/wodalirika kwambiri kuti ibweretse makasitomala mndandanda wazinthu zatsopano komanso zodzaza (mpaka 100V) komanso ntchito zabwino.

Ma capacitor athu a polymer solid aluminiyamu electrolytic, ma capacitor a polymer solid-liquid hybrid aluminiyamu electrolytic, ma multilayer polymer solid aluminiyamu electrolytic, ndi ma polymer tantalum capacitor series onse akhoza kufananizidwa bwino ndi ma converter atsopano a AC/DC.
Ma capacitor oyendetsera magetsi awa amagwiritsidwa ntchito kwambiri mu ma output a 5-20V omwe amagwiritsidwa ntchito kwambiri mu zida za anthu wamba, ma output a 24V pazida zamafakitale, ndi ma output a 48V pazida zolumikizirana. Pofuna kuthana ndi vuto la kusowa kwa magetsi m'zaka zaposachedwa, pakufunika kugwiritsa ntchito bwino kwambiri, ndipo chiwerengero cha zinthu zomwe zikusintha kupita ku 48V chikuwonjezeka (magalimoto, malo osungira deta, USB-PD, ndi zina zotero), zomwe zikukulitsa kwambiri kugwiritsa ntchito kwa ma capacitor a GaN ndi ma conductive.
04 Mapeto
Mu nthawi yatsopano, YMIN ikutsatira lingaliro lautumiki la "Capacitor Solutions, Funsani YMIN za mapulogalamu anu", yatsimikiza mtima kukwaniritsa zofunikira zatsopano ndi zatsopano kudzera mu mapulogalamu atsopano ndi mayankho atsopano, ndipo imayang'ana mwachangu mwayi wochepetsa ma converter a AC/DC pansi pa mapulogalamu a GaN. YMIN ikulimbikira kuyang'ana kwambiri pakupanga zinthu zatsopano, kupanga molondola kwambiri komanso kutsatsa mapulogalamu, kupatsa makasitomala ma capacitor apamwamba kwambiri, kupereka ntchito zatsopano komanso zapamwamba, kuwonjezera ndalama zofufuzira, ndikulimbikitsa kupita patsogolo kwa makampani.
