Ekusetshenzisweni kwalobu buchwepheshe obusha, ama-polymer capacitor adlala indima ebalulekile.Esikhathini esisha, i-YMIN izibophezele ekuzuzeni impumelelo entsha ngokusebenzisa izinhlelo zokusebenza ezintsha futhi ihlola ngenkuthalo amathuba okwenziwa okuncane kweziguquli ze-AC/DC ezisekelwe ku-GaN.
I-YMIN kudala yasebenzisa isivalo se-polymer ezimbonini eziningi, njengokushaja okusheshayo (kusukela ekushajeni okusheshayo kwe-IQ, PD2.0, PD3.0, PD3.1), ama-adaptha e-PC, ukushaja okusheshayo kwe-EV, inqwaba yokushaja okusheshayo ye-OBC/DC , izinsiza zamandla zeseva, njll.
Lawo ma-polymer capacitor angakwazi ukufanisa ngokuphelele izici ezinhle kakhulu ze-GaN, futhi enze kahle ezimweni ezisebenzayo zokuhlangabezana nezidingo zamakhasimende zokwenza ngcono ukusebenza, futhi sizokwethula izici zabo ngokuningiliziwe ngezansi.
Usayizi omncane:I-GaN inikela ekwenziweni okuncane kwesiguquli se-AC/DC.
Ngokuvamile, amasekhethi amaningi asebenzisa amandla kagesi e-DC esikhundleni se-voltage ye-AC, futhi iziguquli ze-AC/DC zibalulekile eziguqula ukunikezwa kwamandla kagesi e-AC kube amandla e-DC.Ngenani elifanayo lamandla, i-miniaturization yeziguquli iwumkhuba ocabangela umbono weukonga isikhala nokuphatheka.
Uma kuqhathaniswa nezinto zendabuko ze-Si (silicon), i-GaN inezinzuzo zeukulahlekelwa okuncane kokushintsha, ukusebenza kahle okuphezulu, isivinini esiphezulu sokufuduka kwama-electron, kanye nokusebenza kahle.
Lokhu kuvumela iziguquli ze-AC/DC ukuthi zilawule ukushintsha imisebenzi ngobunono, okuholela ekutheniukuguqulwa kwamandla okusebenza kahle kakhulu.
Ngaphezu kwalokho, amaza okushintsha aphezulu angakhethwa ukuze kusetshenziswe izingxenye ezincane ze-passive.Lokhu kungenxa yokuthi i-GaN emazingeni aphezulu okushintsha, i-GaN ingakwazi ukugcina ukusebenza kahle okufanayo kwe-Si enikezwe ngefrikhwensi yokushintsha ephansi.
Amasampula ohlelo lokusebenza lweziguquli ze-AC/DC
I-ESR ephansi:I-Ripple voltage ihlale ikhiqizwa lapho i-capacitor ithatha i-ripple current.
Ama-capacitor okukhiphayo abalulekile.I-YMIN polymer capacitor ingasiza ekunciphiseni i-voltage ripple futhi idlale indima ebalulekile#ukuhlungahigh-power switching circuits.
Empeleni, ngokuvamile kuyadingeka ukuthi i-ripple voltage ingeqi1%we-voltage yokusebenza yedivayisi.
Phakathi kwebanga elingu-10KHz~800KHz, iI-ESRye-YMIN's hybrid capacitor izinzile futhi ingakwazi ukuzivumelanisa nezimfuneko zokushintshwa kwe-GAN high-frequency switching.Ngakho-ke, ku-GaN-based AC/DC converters, ama-polymer capacitor ayisixazululo esiphelele sokuphuma.
Ngokusetshenziswa okwandayo kwama-high-frequency switching AC/DC converters, ukuze kuhlangatshezwane nezidingo zokubuyekeza zamakhasimende, i-YMIN, njengomzingeli wezobuchwepheshe obuphambili, onobuchwepheshe bayo obuhamba phambili bokusebenza okuphezulu/obuthembeke kakhulu, iletha imakethe indlela entsha nentsha. uhlelo oluphelele lomkhiqizo (kufika ku-100v).
Izinketho Eziguquguqukayo
I-YMIN polymer solid aluminium electrolytic capacitor, i-polymer hybrid capacitor, i-MLPC, nochungechunge lwe-polymer tantalum capacitor lungafaniswa kahle neziguquli ezintsha ze-AC/DC.
Lawa ma-polymer capacitor asetshenziswa kakhulu emiphumeleni engu-5-20V, imiphumela engu-24V yemishini yezimboni, kanye nemiphumela engu-48V yezinhlobo zenethiwekhi zemishini.Ukuze ubhekane nokushoda kwamandla eminyakeni yamuva, kuyadingeka ukuthola ukusebenza kahle okuphezulu.
Inani lemikhiqizo eshintshela ku-48V (izimoto, isikhungo sedatha, i-USB-PD, njll.) liyakhula, futhi ububanzi bezinhlelo zokusebenza ze-GaN nama-polymer capacitor bunwetshwa ngokuqhubekayo.
Sengiphetha, ukukhetha i-YMIN Polymer E-CAP ye-GaN-based AC/DC Converters kukunikeza ukusebenza okungenakuqhathaniswa, ukuqina, ukwenziwa ngcono kwesikhala, kanye nokufinyelela kulwazi oluhamba phambili embonini - zonke izici ezibalulekile lapho ukhetha ingxenye engcono kakhulu yezidingo zakho zohlelo lokusebenza.
Ngesipiliyoni seminyaka yomkhakha, i-YMIN izenzele igama elithenjwayo ekukhiqizeni izingxenye ze-elekthronikhi.Ubuchwepheshe babo obuhlanganiswe nemizamo eqhubekayo yocwaningo nentuthuko kuqinisekisa ukuthi imikhiqizo yabo ihlezi ihamba phambili ekuthuthukisweni kwezobuchwepheshe.
