Ngokukhula kancane kancane kobuchwepheshe be-gallium nitride (GaN), inani elikhulayo labaguquli be-AC/DC bamukela i-GaN njengezinto ezishintshayo ukuze zithathe indawo yezingxenye ze-silicon zendabuko. Ekusetshenzisweni kwalobu buchwepheshe obusha, ama-capacitor aqhubayo nawo adlala indima ebalulekile.
I-YMIN ibilokhu izibophezele ekuthuthukisweni kwama-capacitor aqhubayo ukuze asetshenziswe kuma-converter e-AC/DC asekelwe ku-GaN futhi ifinyelele izinhlelo zokusebenza eziphumelelayo emikhakheni eminingi, njengokushaja okusheshayo (kusukela esikhathini esidlule sokushaja okusheshayo kwe-IQ, i-PD2.0, i-PD3.0, i-PD3.1), ama-adapter e-laptop, ukushaja okusheshayo kwebhayisikili kagesi, amashaja angaphakathi (ama-OBC)/DC okusheshayo okushaja, izinsiza zamandla eseva, nokuningi. Lawa ma-capacitor amasha aqhubayo angagcwalisa ngokugcwele izici ezinhle kakhulu ze-GaN, enza kahle kakhulu ezimweni zohlelo lokusebenza olusebenzayo futhi ahlangabezane nezidingo zamakhasimende zokuthuthukisa ukusebenza kanye nokuthuthukiswa okuphindaphindiwe. Ngezansi, sizochaza izici zabo zohlelo lokusebenza.
01 I-GaN isiza ukunciphisa ama-converter e-AC/DC
Amasekethe amaningi asebenzisa i-DC voltage esikhundleni se-AC voltage, futhi ama-AC converter abalulekile njengamadivayisi aguqula amandla e-AC ebhizinisi anikezwa emakhaya nasemabhizinisini abe amandla e-DC. Uma amandla efana, umkhuba uwukwenza ama-converter abe mancane ngokombono wokonga isikhala kanye nokuphatheka kalula.
Ukusetshenziswa kwe-GaN (gallium nitride) kuye kwaba nentuthuko enkulu ekunciphisweni kwe-AC/DC converters. Uma kuqhathaniswa nezingxenye ze-Si (silicon) zendabuko, izinzuzo ze-GaN ukulahlekelwa okuncane kokushintsha, ukusebenza kahle okuphezulu, isivinini sokufuduka kwama-electron aphezulu kanye nezakhiwo zokuqhuba. Lokhu kuvumela i-AC/DC converter ukuthi ilawule kahle imisebenzi yokushintsha, okuholela ekuguqulweni kwamandla okusebenza kahle kakhulu.
Ngaphezu kwalokho, amaza okushintsha aphezulu angakhethwa, okuvumela ukusetshenziswa kwezingxenye ezincane ezingasebenzi. Lokhu kungenxa yokuthi i-GaN ingagcina ukusebenza kahle okuphezulu ngisho nasekushintsheni kwamaza aphezulu, okufana nokushintsha kwamaza aphansi kwe-Si.
02 Indima ebalulekile yeama-capacitor aqhubayo
Ekwakhiweni kwama-converter e-AC/DC, ama-capacitor okukhipha abalulekile. Ama-capacitor aqhubayo angasiza ekunciphiseni i-ripple ye-voltage yokukhipha futhi adlala indima ebalulekile ekuhlungeni kumasekethe okushintsha amandla aphezulu. Lapho i-capacitor imunca i-ripple current, izokhiqiza i-ripple voltage ngokungenakugwenywa. Ezisetshenzisweni ezingokoqobo, ngokuvamile kuyadingeka ukuthi i-ripple yokunikezwa kwamandla ingadluli i-1% ye-voltage yokusebenza yemishini.
Uma kusetshenziswa i-GaN, i-ESR yama-capacitor e-YMIN solid-liquid hybrid izinzile ebangeni elibanzi elingu-10KHz ~ 800KHz, elingahlangabezana nezidingo zokushintsha kwe-GAN high-frequency.
Ngakho-ke, kuma-converter e-AC/DC asebenzisa i-gallium nitride, ama-capacitor aqhubayo aba ama-capacitor aphumayo angcono kakhulu.
03 I-YMIN ifaniswe ne-capacitor yokuqhuba ehambisanayo
Ngokwamukelwa kwe-GaN, ukusetshenziswa kwama-converter e-AC/DC ashintshashintshayo avame ukwanda kancane kancane. Ukuze kuqhutshekwe nokuhlangabezana nezidingo ezishintshayo zamakhasimende, i-YMIN, njengomsunguli wemakethe kuma-capacitor aqhubayo, isebenzisa ubuchwepheshe bayo obusezingeni eliphezulu bokusebenza okuphezulu/ukuthembeka okuphezulu ukuze ilethe amakhasimende uhlu lwemikhiqizo oluphelele nolusha (olufika ku-100V) kanye nezinsizakalo zekhwalithi.

Ama-capacitor ethu e-polymer solid aluminium electrolytic, ama-capacitor e-polymer solid-liquid aluminium hybrid electrolytic, ama-polymer solid aluminium electrolytic amaningi, kanye nemikhiqizo yochungechunge lwe-polymer tantalum capacitor ingalinganiswa kahle nama-converter amasha e-AC/DC.
Lawa ma-capacitor aqhuba ugesi asetshenziswa kabanzi emikhiqizweni engu-5-20V esetshenziswa kakhulu emishinini yabantu, emikhiqizweni engu-24V yemishini yezimboni, kanye nemikhiqizweni engu-48V yemishini yokuxhumana. Ukuze kuhlangatshezwane nenkinga yokushoda kwamandla eminyakeni yamuva nje, kudingeka ukusebenza kahle okuphezulu, futhi inani lemikhiqizo elishintshela ku-48V liyakhula (izimoto, izikhungo zedatha, i-USB-PD, njll.), okwandisa ububanzi bokusetshenziswa kwama-capacitor e-GaN kanye nama-capacitor aqhuba ugesi.
04 Isiphetho
Enkathini entsha, i-YMIN inamathela emcabangweni wesevisi we-“Capacitor Solutions, Buza i-YMIN ngezinhlelo zakho zokusebenza”, izimisele ukufeza izidingo ezintsha kanye nokuthuthuka okusha ngezinhlelo zokusebenza ezintsha kanye nezixazululo ezintsha, futhi ihlola ngenkuthalo amathuba okunciphisa ama-converter e-AC/DC ngaphansi kwezinhlelo zokusebenza ze-GaN. I-YMIN iphikelela ekugxileni ekuthuthukisweni komkhiqizo omusha, ukukhiqizwa okunembe kakhulu kanye nokukhushulwa kokuphela kwezicelo, ukuhlinzeka amakhasimende ngama-capacitor aqhubayo asezingeni eliphezulu, ukuhlinzeka ngezinsizakalo ezintsha nezisezingeni eliphezulu, ukwandisa ukutshalwa kwezimali ocwaningweni, kanye nokukhuthaza intuthuko embonini.
