Ngokuvuthwa kancane kancane kobuchwepheshe be-gallium nitride (GaN), inani elandayo labaguquli be-AC/DC bamukela i-GaN njengezinto ezishintshayo ukuze zingene esikhundleni sezingxenye ze-silicon zendabuko. Ekusetshenzisweni kwalobu buchwepheshe obusha, ama-conductive capacitor nawo adlala indima ebalulekile.
I-YMIN sekuyisikhathi eside izibophezele ekuthuthukiseni ama-conductive capacitor azosetshenziswa kuziguquli ze-AC/DC ezisekelwe ku-GaN futhi izuze izinhlelo zokusebenza eziyimpumelelo kuzo zonke izimboni eziningi, njengokushaja okusheshayo (kusukela ekushajweni okusheshayo kwe-IQ, PD2.0, PD3.0, PD3.1), ama-adaptha aphathekayo, ukushaja okusheshayo kwebhayisikili kagesi, amashaja angaphakathi (OBC)/DC izinqwaba zokushaja ngokushesha, izinsiza zamandla zeseva, nokuningi. Lawa ma-capacitor amasha angakwazi ukuhambisana ngokugcwele nezici ezinhle kakhulu ze-GaN, asebenze kahle kakhulu ezimeni zohlelo lokusebenza futhi ahlangabezane nezidingo zamakhasimende zokuthuthukisa ukusebenza nokuthuthukiswa okuphindaphindiwe. Ngezansi, sizochaza izici zabo zohlelo lokusebenza.
I-01 GaN isiza ukwenza iziguquli ze-AC/DC zibe zincane
Amasekhethi amaningi asebenzisa amandla kagesi e-DC esikhundleni se-voltage ye-AC, futhi iziguquli ze-AC/DC zibalulekile njengamadivayisi aguqula amandla e-AC athengiswayo anikezwa ezindlini namabhizinisi abe amandla e-DC. Uma amandla afana, inkambiso iwukwenza iziguquli zibe zincane ngokombono wokonga isikhala nokuphatheka.
Ukusetshenziswa kwe-GaN (i-gallium nitride) kwenze inqubekelaphambili ebalulekile ekusetshenzisweni okuncane kweziguquli ze-AC/DC. Uma kuqhathaniswa nezingxenye zendabuko ze-Si (silicon), izinzuzo ze-GaN ukulahlekelwa okuncane kokushintsha, ukusebenza kahle okuphezulu, isivinini esiphezulu sokufuduka kwama-electron kanye nezakhiwo zokuqhuba. Lokhu kuvumela isiguquli se-AC/DC ukuthi silawule kangcono ukusebenza kokushintsha, okuholela ekuguqulelweni kwamandla okusebenza kahle kakhulu.
Ngaphezu kwalokho, ama-switch frequency frequency aphezulu angakhethwa, okuvumela ukusetshenziswa kwezingxenye ezincane ze-passive. Lokhu kungenxa yokuthi i-GaN ingakwazi ukugcina ukusebenza kahle okuphezulu ngisho nasekushintsheni kwefrikhwensi ephezulu, okuqhathaniswa nokushintshwa kwefrikhwensi ye-Si.
02 Indima ebalulekile yeama-conductive capacitors
Ekwakhiweni kweziguquli ze-AC/DC, ama-capacitor okukhiphayo abalulekile. Ama-capacitor e-conductive angasiza ekunciphiseni ukugeleza kwamandla kagesi futhi adlale indima ebalulekile ekuhlungeni kumasekhethi okushintsha amandla aphezulu. Lapho i-capacitor idonsa i-ripple current, nakanjani izokhiqiza i-voltage ye-ripple. Ezinhlelweni ezingokoqobo, ngokuvamile kuyadingeka ukuthi i-ripple yokunikezwa kwamandla ingeqi u-1% wevoltage yokusebenza yempahla.
Uma i-GaN isetshenziswa, i-ESR ye-YMIN solid-liquid hybrid capacitor izinzile kubange elibanzi lika-10KHz~800KHz, elingahlangabezana nezimfuneko zokushintshwa kwe-GAN high-frequency.
Ngakho-ke, kuma-converter e-AC/DC asebenzisa i-gallium nitride, ama-conductive capacitor aba ama-capacitor okukhiphayo angcono kakhulu.
03 YMIN ifaniswe ne-conductivity capacitor ehambisanayo
Ngokwamukelwa kwe-GaN, ukusetshenziswa kweziguquli ze-AC/DC zokushintshwa kwe-high-frequency kuye kwanda kancane kancane. Ukuze iqhubeke nokuhlangabezana nezidingo ezishintshayo zamakhasimende, i-YMIN, njengomsunguli wemakethe kuma-conductive capacitor, isebenzisa ubuchwepheshe bayo bokusebenza okuphezulu/obuthembeke kakhulu ukuletha amakhasimende ukwakheka okusha, okubanzi komkhiqizo (kufika ku-100V) kanye nekhwalithi. amasevisi.

I-polymer solid aluminium electrolytic capacitor yethu, i-polymer solid-liquid hybrid electrolytic capacitor, i-multilayer polymer solid aluminium electrolytic, kanye nemikhiqizo yochungechunge lwe-polymer tantalum capacitor konke kungafaniswa kahle neziguquli ezintsha ze-AC/DC.
Lawa ma-conductive capacitor asetshenziswa kakhulu emiphumeleni engu-5-20V esetshenziswa kakhulu ezintweni ezisetshenziswa umphakathi, imiphumela engu-24V yemishini yezimboni, kanye nemiphumela engu-48V yemishini yezokuxhumana. Ukuze ubhekane nenkinga yokushoda kwamandla eminyakeni yamuva nje, kudingeka ukusebenza kahle okuphezulu, futhi inani lemikhiqizo eshintshela ku-48V liyakhula (izimoto, izikhungo zedatha, i-USB-PD, njll.), ngokuqhubekayo nokwandisa ububanzi bokusebenza kwe-GaN kanye ama-conductive capacitors.
04 Isiphetho
Esikhathini esisha, i-YMIN ibambelela emcabangweni wesevisi othi “Capacitor Solutions, Cela u-YMIN ngezinhlelo zakho zokusebenza”, izimisele ukufeza izidingo ezintsha kanye nokuphumelela okusha ngokusebenzisa izinhlelo zokusebenza ezintsha nezisombululo ezintsha, futhi ihlola ngenkuthalo amathuba okwenziwa okuncane kwe-AC/DC. iziguquli ngaphansi kwezinhlelo zokusebenza ze-GaN. I-YMIN iphikelela ekugxileni ekuthuthukisweni kwemikhiqizo emisha, ukukhiqizwa okunembayo okuphezulu kanye nokukhuthazwa kokuphela kwesicelo, ukuhlinzeka amakhasimende ngama-capacitor conductive ekhwalithi ephezulu, ukuhlinzeka ngezinsizakalo ezintsha nezisezingeni eliphezulu, ukwandisa ukutshalwa kwezimali kocwaningo, nokukhuthaza inqubekelaphambili yemboni.
