Ndi kukhwima kwapang'onopang'ono kwaukadaulo wa gallium nitride (GaN), kuchuluka kwa otembenuza a AC/DC akutenga GaN ngati zinthu zosinthira kuti zilowe m'malo mwa zida zachikhalidwe za silicon. Pogwiritsa ntchito ukadaulo watsopanowu, ma conductive capacitor amakhalanso ndi gawo lofunikira.
YMIN yakhala ikudzipereka pakupanga ma conductive capacitor kuti agwiritsidwe ntchito posinthira ku GaN-based AC/DC ndipo yakwanitsa kugwiritsa ntchito bwino m'mafakitale angapo, monga kulipiritsa mwachangu (kuyambira pa IQ yothamangitsa mwachangu, PD2.0, PD3.0, PD3.1), ma adapter a laputopu, kuthamangitsa njinga yamagetsi yamagetsi, ma charger okwera (OBC)/DC milu yothamangitsa mwachangu, magetsi a seva, ndi zina zambiri. Ma capacitor atsopanowa amatha kukwaniritsa bwino kwambiri mawonekedwe a GaN, kuchita bwino kwambiri pazogwiritsa ntchito komanso kukwaniritsa zosowa zamakasitomala pakuwongolera magwiridwe antchito komanso kukweza kobwerezabwereza. Pansipa, tifotokoza mwatsatanetsatane mawonekedwe awo ogwiritsira ntchito.
01 GaN imathandiza kuchepetsa otembenuza a AC/DC
Mabwalo ambiri amagwiritsa ntchito magetsi a DC m'malo mwa magetsi a AC, ndipo zosinthira za AC/DC ndizofunikira ngati zida zomwe zimasinthira magetsi a AC amalonda omwe amaperekedwa kunyumba ndi mabizinesi kukhala magetsi a DC. Mphamvu ikakhala yofanana, zomwe zimachitika ndikuchepetsa otembenuza kuchokera kumalingaliro opulumutsa danga ndi kunyamula.
Kugwiritsiridwa ntchito kwa GaN (gallium nitride) kwapita patsogolo kwambiri mu miniaturization ya otembenuza AC / DC. Poyerekeza ndi zida zachikhalidwe za Si (silicon), zabwino za GaN ndizotayika zosinthika zazing'ono, kuchita bwino kwambiri, kuthamanga kwapamwamba kwa ma elekitironi ndi ma conductive katundu. Izi zimalola chosinthira cha AC/DC kuti chizitha kuyendetsa bwino ntchito zosinthira, zomwe zimapangitsa kutembenuka kwamphamvu kwamphamvu.
Kuphatikiza apo, ma frequency osintha kwambiri amatha kusankhidwa, kulola kugwiritsa ntchito zigawo zing'onozing'ono zongokhala. Izi ndichifukwa choti GaN imatha kukhalabe yogwira ntchito kwambiri ngakhale pakusintha kwanthawi yayitali, kufananiza ndikusintha kwapakati kwa Si.
02 Udindo wofunikira waconductive capacitors
Popanga ma converter a AC/DC, ma capacitor otulutsa ndi ofunikira. Ma conductive capacitor amatha kuthandizira kuchepetsa kutsika kwamagetsi otulutsa ndikuchita gawo lofunikira pakusefa mumayendedwe osinthira mphamvu kwambiri. Pamene capacitor itenga mphamvu yapano, imatulutsa mphamvu yamagetsi. M'magwiritsidwe ntchito, nthawi zambiri pamafunika kuti mphamvu yamagetsi isapitirire 1% yamagetsi ogwiritsira ntchito zida.
Ngati GaN itagwiritsidwa ntchito, ESR ya YMIN solid-liquid hybrid capacitors imakhala yokhazikika pamitundu yambiri ya 10KHz~800KHz, yomwe ingakwaniritse zofunikira za GAN high-frequency switching.
Chifukwa chake, mu otembenuza a AC/DC pogwiritsa ntchito gallium nitride, ma conductive capacitor amakhala otulutsa bwino kwambiri.
03 YMIN yofanana ndi capacitor yofananira
Ndi kukhazikitsidwa kwa GaN, kugwiritsa ntchito makina osinthika a AC / DC okwera kwambiri kwawonjezeka pang'onopang'ono. Kuti apitilize kukwaniritsa zosowa za makasitomala, YMIN, monga woyambitsa msika mu ma capacitor oyendetsa, amagwiritsa ntchito ukadaulo wake wapamwamba kwambiri / wodalirika kwambiri kuti abweretse makasitomala zatsopano, zopangira zinthu zambiri (mpaka 100V) komanso mtundu. ntchito.

Ma polymer solid aluminium electrolytic capacitor athu, ma polymer solid-liquid hybrid aluminium electrolytic capacitors, multilayer polymer solid aluminium electrolytic, ndi zinthu zapolymer tantalum capacitor zitha kufananizidwa bwino ndi zosinthira zatsopano za AC/DC.
Ma capacitor oyendetsa awa amagwiritsidwa ntchito kwambiri pazotulutsa za 5-20V zomwe zimagwiritsidwa ntchito kwambiri pazida wamba, zotulutsa 24V pazida zamafakitale, ndi zotulutsa 48V pazida zoyankhulirana. Kuti muthe kuthana ndi vuto la kuchepa kwa magetsi m'zaka zaposachedwa, kuchita bwino kwambiri kumafunika, ndipo kuchuluka kwa zinthu zomwe zikusintha kupita ku 48V zikuchulukirachulukira (magalimoto, malo opangira data, USB-PD, ndi zina), ndikukulitsa kuchuluka kwa ntchito za GaN ndi conductive capacitors.
04 Mapeto
M'nthawi yatsopano, YMIN imatsatira lingaliro lautumiki la "Capacitor Solutions, Funsani YMIN pazofunsira zanu", yatsimikiza kukwaniritsa zofunikira zatsopano ndi zopambana zatsopano kudzera muzofunsira zatsopano ndi mayankho atsopano, ndikuwunika mwachangu chiyembekezo cha miniaturization ya AC/DC. otembenuza pansi pa mapulogalamu a GaN. YMIN ikugogomezera kuyang'ana pa chitukuko chatsopano cha mankhwala, kupanga mwatsatanetsatane komanso kupititsa patsogolo ntchito, kupatsa makasitomala ma capacitor apamwamba kwambiri, kupereka ntchito zatsopano komanso zapamwamba, kuonjezera ndalama zofufuzira, ndi kulimbikitsa kupita patsogolo kwa makampani.
