Ekusetyenzisweni kobu buchwepheshe butsha, ii-polymer capacitors zidlala indima ebalulekileyo. Kwixesha elitsha, i-YMIN izibophelele ekufezekiseni impumelelo entsha ngokusebenzisa usetyenziso olutsha kwaye ihlola ngenkuthalo amathuba okunciphisa i-AC/DC converters esekwe kwi-GaN.
I-YMIN ibisoloko isetyenziswa njenge-polymer cap kumashishini amaninzi, njengokutshaja ngokukhawuleza (ukusuka kwixesha elidlulileyo lokutshaja ngokukhawuleza kwe-IQ, i-PD2.0, i-PD3.0, i-PD3.1), ii-adapters zePC, ukutshaja ngokukhawuleza kwe-EV, ii-OBC/DC fast charging piles, izixhobo zamandla zeseva, njl.njl.
Ezo capacitors zepolymer zinokulingana ngokugqibeleleyo neempawu ezibalaseleyo zeGaN, kwaye zisebenze kakuhle kwiimeko zokusetyenziswa ukuze zihlangabezane neemfuno zabathengi zokuphucula ukusebenza, kwaye siza kwazisa iimpawu zazo ngokweenkcukacha ngezantsi.
Ubungakanani obuncinci:I-GaN inegalelo ekwenzeni i-AC/DC converter ibe yincinci.
Ngokubanzi, uninzi lweesekethe zisebenzisa i-DC voltage endaweni ye-AC voltage, kwaye ii-AC/DC converters zibalulekile ekuguquleni umbane we-AC yorhwebo ube ngumbane we-DC. Ngomlinganiselo ofanayo wamandla, ukwenziwa kube lula kwee-converters yindlela ethathwa ngayo xa kujongwa umbono we-ukonga indawo kunye nokuphatheka lula.
Xa kuthelekiswa nezinto zeSi (silicon) zemveli, iGaN ineenzuzo zokubailahleko ezincinci zokutshintsha, ukusebenza kakuhle okuphezulu, isantya esiphezulu sokufuduka kwee-electron, kunye nokuqhuba kombane.
Oku kwenza abaguquli be-AC/DC bakwazi ukulawula imisebenzi yokutshintsha ngobuchule, nto leyo ebangela ukubaukuguqulwa kwamandla okusebenzayo ngakumbi.
Ukongeza, ii-switching frequencies eziphezulu zinokukhethwa ukuze kusetyenziswe izinto ezincinci ezingasebenziyo. Oku kungenxa yokuba i-GaN kwi-switching frequency ephezulu, i-GaN inokugcina ukusebenza kakuhle okufanayo kwe-Si enikezelwa kwi-switching frequency ephantsi.
Iisampulu zesicelo see-AC/DC converters
I-ESR ephantsi:I-voltage ye-Ripple ihlala iveliswa xa i-capacitor ifunxa i-ripple current.
Ii-capacitors ze-output zibalulekile. Ii-capacitors ze-YMIN polymer zinokunceda ekunciphiseni i-output voltage ripple kwaye zidlala indima ebalulekileyo kwi#ukucocaiisekethe zokutshintsha amandla aphezulu.
Ngokwenyani, kudla ngokufuneka ukuba i-ripple voltage ingadluli1%yevolthi yokusebenza yesixhobo.
Ngaphakathi koluhlu lwe-10KHz ~ 800KHz,I-ESRI-capacitor ye-YMIN exutyiweyo izinzile kwaye inokuziqhelanisa neemfuno zokutshintsha kwe-GAN ephezulu. Ke ngoko, kwii-converters ze-AC/DC ezisekwe kwi-GaN, ii-capacitors ze-polymer zisisombululo esigqibeleleyo sokukhupha.
Ngokusetyenziswa kakhulu kwee-converter ze-AC/DC ezitshintsha rhoqo, ukuze kuhlangatyezwane neemfuno zokuhlaziya zabathengi, i-YMIN, njengomzingeli wezobuchwepheshe obuphambili, kunye netekhnoloji yayo ephambili yokusebenza okuphezulu/ukuthembeka okuphezulu, izisa imakethi uluhlu lwemveliso entsha nebanzi (ukuya kuthi ga kwi-100v).
Iinketho eziguquguqukayo
Ii-capacitors ze-electrolytic ze-YMIN polymer solid aluminium electrolytic, ii-polymer hybrid capacitors, i-MLPC, kunye ne-polymer tantalum capacitor series zinokufaniswa ngokufanelekileyo neziguquli ezintsha ze-AC/DC.
Ezi capacitors zepolymer zisetyenziswa kakhulu kwiziphumo ze-5-20V, iziphumo ze-24V kwizixhobo zoshishino, kunye neziphumo ze-48V kwiintlobo zezixhobo zenethiwekhi. Ukuze kuhlangatyezwane nokunqongophala kwamandla kwiminyaka yakutshanje, kuyimfuneko ukufumana ukusebenza okuphezulu.
Inani leemveliso ezitshintshela kwi-48V (iimoto, iziko ledatha, i-USB-PD, njl.njl.) liyanda, kwaye uluhlu lwezicelo ze-GaN kunye nee-polymer capacitors luyandiswa ngakumbi.
Ukuqukumbela, ukukhetha i-YMIN Polymer E-CAP yee-AC/DC Converters ezisekelwe kwiGaN kukunika ukusebenza okungenakuthelekiswa nanto, ukuqina, ukulungiswa kwendawo, kunye nokufikelela kulwazi oluphambili kushishino - zonke ezi zinto zibalulekileyo xa ukhetha eyona nxalenye ifanelekileyo kwiimfuno zesicelo sakho.
Ngamava eminyaka emininzi kushishino, i-YMIN izibonakalise njengegama elithembekileyo kwimveliso yezinto ze-elektroniki. Ubuchule bayo kunye nemizamo yophando oluqhubekayo kunye nophuhliso iqinisekisa ukuba iimveliso zabo zihlala ziphambili kuphuhliso lwetekhnoloji.
