Ngokukhula kancinci kancinci kwetekhnoloji ye-gallium nitride (GaN), inani elikhulayo labaguquli be-AC/DC bamkela i-GaN njengezinto ezitshintshayo ukuze zithathe indawo yezixhobo ze-silicon zemveli. Ekusetyenzisweni kobu buchwepheshe butsha, ii-capacitors eziqhubayo nazo zidlala indima ebalulekileyo.
I-YMIN ibisoloko izibophelele ekuphuhliseni ii-capacitors eziqhuba umbane ezisetyenziswa kwii-converters ze-AC/DC ezisekelwe kwi-GaN kwaye iphumelele kwizicelo eziphumelelayo kumashishini amaninzi, njengokutshaja ngokukhawuleza (ukusuka kwi-IQ fast charging yangaphambili, i-PD2.0, i-PD3.0, i-PD3.1), ii-adapters zelaptop, ukutshaja ngokukhawuleza kwebhayisekile yombane, ii-onboard chargers (OBC)/DC fast charging piles, izixhobo zamandla zeseva, nokunye. Ezi capacitors zintsha eziqhuba umbane zinokuzalisa ngokupheleleyo iimpawu ezibalaseleyo ze-GaN, zisebenza kakuhle kwiimeko zesicelo esisebenzayo kwaye zihlangabezana neemfuno zabathengi zokuphucula ukusebenza kunye nokuphucula okuphindaphindayo. Ngezantsi, siza kuchaza iimpawu zabo zesicelo.
I-01 GaN inceda ukunciphisa ii-AC/DC converters
Uninzi lweesekethe zisebenzisa i-DC voltage endaweni ye-AC voltage, kwaye ii-AC/DC converters zibalulekile njengezixhobo eziguqula umbane we-AC wezorhwebo onikezelwa emakhaya nakwiishishini ube ngumbane we-DC. Xa umbane ufana, umkhwa kukwenza ii-converters zibe zincinci ngokwembono yokonga indawo kunye nokuphatheka lula.
Ukusetyenziswa kweGaN (gallium nitride) kuye kwenza inkqubela phambili enkulu ekuguquleni ii-AC/DC converters ezincinci. Xa kuthelekiswa nezinto zeSi (silicon) zemveli, iingenelo zeGaN kukulahlekelwa okuncinci kokutshintsha, ukusebenza kakuhle, isantya esiphezulu sokufuduka kwee-electron kunye neempawu zokuqhuba. Oku kuvumela i-AC/DC converter ukuba ilawule kakuhle imisebenzi yokutshintsha, nto leyo ekhokelela ekuguqulweni kwamandla okusebenzayo ngakumbi.
Ukongeza, ii-frequency eziphezulu zokutshintsha zinokukhethwa, okuvumela ukusetyenziswa kwezinto ezincinci ezingasebenziyo. Oku kungenxa yokuba i-GaN inokugcina ukusebenza okuphezulu nokuba kukutshintsha okuphezulu, okufana nokutshintsha okuphantsi kwe-Si.
02 Indima ebalulekileyoii-capacitor eziqhubayo
Kuyilo lwee-AC/DC converters, ii-output capacitors zibalulekile. Ii-conductive capacitors zinokunceda ukunciphisa i-ripple ye-output voltage kwaye zidlala indima ebalulekileyo ekuhluzeni kwiisekethe zokutshintsha amandla aphezulu. Xa i-capacitor ifunxa i-ripple current, ngokuqinisekileyo iya kuvelisa i-ripple voltage. Kwiindlela ezisebenzayo, kudla ngokufuneka ukuba i-power supply ripple ingadluli kwi-1% ye-operate yokusebenza yesixhobo.
Ukuba kusetyenziswa iGaN, i-ESR yee-capacitors ze-YMIN solid-liquid hybrid izinzile kuluhlu olubanzi lwe-10KHz ~ 800KHz, enokwanelisa iimfuno zokutshintsha kwe-GAN ngesantya esiphezulu.
Ke ngoko, kwii-AC/DC converters ezisebenzisa i-gallium nitride, ii-conductive capacitors ziba zezona capacitors zibalaseleyo.
03 YMIN ifaniswe ne-capacitor yokuqhuba ehambelanayo
Ngokusetyenziswa kweGaN, ukusetyenziswa kwee-AC/DC converters ezitshintsha rhoqo kuye kwanda kancinci kancinci. Ukuze kuqhubeke nokuhlangabezana neemfuno ezitshintshayo zabathengi, i-YMIN, njengomyili wemarike kwii-capacitors eziqhubayo, isebenzisa iteknoloji yayo yanamhlanje esebenza kakuhle/ethembekileyo ukuzisa abathengi uluhlu lwemveliso olupheleleyo (ukuya kuthi ga kwi-100V) kunye neenkonzo ezisemgangathweni.
