Ihashe elilungileyo lifanelwe yisali elungileyo! Ukuphucula ngokupheleleyo iingenelo zezixhobo ze-SiC, kuyafuneka kwakhona ukudibanisa inkqubo yesiphaluka kunye ne-capacitors efanelekileyo. Ukusuka kulawulo oluphambili lokuqhuba kwizithuthi zombane ukuya kumandla anamandla amakhulu eemeko ezifana ne-photovoltaic inverters, ii-capacitors zefilimu ngokuthe ngcembe ziba yinto eqhelekileyo, kwaye intengiso ifuna ngokukhawuleza iimveliso ezinexabiso eliphezulu.
Kutshanje, i-Shanghai Yongming Electronic Co., Ltd. yasungula i-DC yenkxaso yefilimu capacitors, eneenzuzo ezine ezibalaseleyo ezenza zilungele i-IGBT yesizukulwana sesixhenxe se-Infineon. Bakwanceda ukujongana nemingeni yokuzinza, ukuthembeka, i-miniaturization, kunye neendleko kwiinkqubo ze-SiC.
Ifilim capacitors ifikelela phantse i-90% yokungena kwiinkqubo eziphambili zokuqhuba. Kutheni iSiC kunye ne-IGBT bezifuna?
Kwiminyaka yakutshanje, ngophuhliso olukhawulezayo lwamashishini anamandla amatsha afana nokugcinwa kwamandla, ukutshaja, kunye nezithuthi zombane (EVs), imfuno ye-DC-Link capacitors iye yanda ngokukhawuleza. Ukubeka nje ngokulula, ii-DC-Link capacitors zisebenza njengezithinteli kwiisekethe, zifunxa imisinga yepulse ephezulu ukusuka esiphelweni sebhasi kunye nombane webhasi ogudileyo, ngaloo ndlela ikhusela iiswitshi ze-IGBT kunye ne-SiC MOSFET ukusuka kwimisinga yepulse ephezulu kunye neempembelelo zamandla ombane wethutyana.
Ngokuqhelekileyo, i-aluminium electrolytic capacitors isetyenziswa kwizicelo zenkxaso ye-DC. Nangona kunjalo, nge-voltage yebhasi yezithuthi zamandla amatsha enyuka ukusuka kwi-400V ukuya kwi-800V kunye neenkqubo ze-photovoltaic eziya kwi-1500V kunye nakwi-2000V, imfuno ye-filimi capacitors ikhula kakhulu.
Idatha ibonisa ukuba kwi-2022, umthamo ofakiweyo we-inverters zombane zombane ezisekelwe kwi-DC-Link film capacitors zifikelele kwi-5.1117 yezigidi zeeyunithi, zibalwa kwi-88.7% yomthamo ofakiweyo wolawulo lwe-elektroniki. Iinkampani ezikhokelayo zokulawula i-elektroniki ezifana ne-Fudi Power, i-Tesla, i-Inovance Technology, i-Nidec, kunye ne-Wiran Power zonke zisebenzisa i-DC-Link i-capacitor yefilimu kwii-inverters zabo zokuqhuba, kunye nomlinganiselo womthamo odibeneyo ofakiweyo ukuya kwi-82.9%. Oku kubonisa ukuba ii-capacitors zefilimu zithathe indawo ye-electrolytic capacitors njengeyona nto iphambili kwimarike yokuqhuba umbane.
Oku kungenxa yokuba ubuninzi bokumelana kwamandla ombane we-aluminium electrolytic capacitors malunga ne-630V. Kwi-voltage ephezulu kunye nezicelo zamandla aphezulu ngaphezu kwe-700V, i-electrolytic capacitors ezininzi kufuneka zixhunywe kwi-series kunye ne-parallel ukuhlangabezana neemfuno zokusetyenziswa, ezizisa ukulahlekelwa kwamandla okongezelelweyo, iindleko ze-BOM, kunye nemiba yokuthembeka.
Iphepha lophando elivela kwiDyunivesithi yaseMalaysia libonisa ukuba i-electrolytic capacitors idla ngokusetyenziswa kwikhonkco le-DC le-silicon IGBT i-half-bridge inverters, kodwa ukunyuka kwamandla ombane kunokwenzeka ngenxa yokumelana nochungechunge olulinganayo (ESR) lwee-electrolytic capacitors. Xa kuthelekiswa nezisombululo ze-IGBT ezisekwe kwisilicon, ii-SiC MOSFETs zinee-frequencies eziphezulu zokutshintsha, okukhokelela ekunyukeni kwamandla ombane aphezulu kwikhonkco le-DC le-half-bridge inverters. Oku kunokukhokelela ekuthotyweni kokusebenza kwesixhobo okanye nokonakala, njengoko ukuphindaphindwa kwe-resonant ye-electrolytic capacitors iyi-4kHz kuphela, akwanelanga ukufunxa i-ripple yangoku ye-SiC MOSFET inverters.
Ke ngoko, kwizicelo ze-DC ezineemfuno eziphezulu zokuthembeka, ezinje ngee-inverters zombane kunye ne-photovoltaic inverters, ii-capacitors zefilimu zikhethwa ngokuqhelekileyo. Xa kuthelekiswa ne-aluminiyam electrolytic capacitors, izibonelelo zokusebenza kwazo ziquka ukuxhathisa kwamandla ombane aphezulu, i-ESR esezantsi, akukho polarity, ukusebenza okuzinzile, kunye nobomi obude, okubangela uyilo lwenkqubo oluthembeke ngakumbi olunokumelana okunamandla.
Ukongezelela, ukusebenzisa ii-capacitors zefilimu kwinkqubo kunokunyusa ngokuphindaphindiweyo i-high-frequency, ilahleko ephantsi inzuzo ye-SiC MOSFETs, ukunciphisa kakhulu ubungakanani kunye nobunzima bezinto ezingabonakaliyo (i-inductors, i-transformers, i-capacitors) kwinkqubo. Ngokutsho kophando lweWolfspeed, i-10kW silicon-based IGBT inverter idinga i-22 aluminium electrolytic capacitors, kanti i-40kW SiC inverter idinga kuphela i-capacitors yefilimu ye-8, ukunciphisa kakhulu indawo ye-PCB.
I-YMIN Ikhupha iiCapacitors zeFilimu eziNtsha ezineNgcebiso ezine eziNcedayo eziNcedayo ukuxhasa iShishini laMandla amatsha
Ukujongana neemfuno ezingxamisekileyo zeemarike, i-YMIN isandul 'ukuqalisa i-MDP kunye ne-MDR uchungechunge lwe-DC yenkxaso yefilimu capacitors.

Okwesibini, ii-capacitors zefilimu ze-YMIN zamva nje zinokuvuza okuphantsi kwangoku kunye nokuzinza okuphezulu kobushushu. Kwimeko yeenkqubo zokulawula i-elektroniki yemoto yombane, ngokuqhelekileyo inamandla amakhulu, ukuveliswa kokushisa okubangelwayo kunokuchaphazela kakhulu ixesha lokuphila kunye nokuthembeka kwee-capacitors zefilimu. Ukujongana nale nto, i-MDP kunye ne-MDR uchungechunge oluvela kwi-YMIN lubandakanya izinto ezisemgangathweni ophezulu kunye nobuchule obuphezulu bokuvelisa ukuyila isakhiwo esiphuculweyo se-thermal kwi-capacitors. Oku kuqinisekisa ukusebenza okuzinzileyo nakwiindawo eziphezulu zokushisa, ukuthintela ukuthotywa kwexabiso le-capacitor okanye ukungaphumeleli ngenxa yokunyuka kweqondo lokushisa. Ngaphaya koko, ezi capacitors zinobomi obude, zibonelela ngenkxaso ethembekileyo yeenkqubo zombane zamandla.
Okwesithathu, i-MDP kunye ne-MDR series capacitors ezivela kwi-YMIN zibonisa ubungakanani obuncinci kunye noxinano lwamandla aphezulu. Ngokomzekelo, kwiinkqubo ze-800V zombane zombane, umkhwa kukusebenzisa izixhobo ze-SiC ukunciphisa ubungakanani be-capacitors kunye nezinye izinto ezingabonakaliyo, ngaloo ndlela kukhuthazwa i-miniaturization yolawulo lwe-elektroniki. I-YMIN iqeshe iteknoloji yokuvelisa ifilimu entsha, engagcini nje ukwandisa ukuhlanganiswa kwenkqubo yonke kunye nokusebenza kakuhle kodwa inciphisa ubungakanani benkqubo kunye nobunzima, ukuphucula ukuthwala kunye nokuguquguquka kwezixhobo.
Ngokubanzi, i-YMIN's DC-Link film capacitor series ibonelela nge-30% yokuphucula kwi-dv/dt yokumelana nesakhono kunye nokunyuka kwe-30% kubomi bokuphila xa kuthelekiswa nezinye ii-capacitors zefilimu kwimarike. Oku akunikezeli kuphela ukuthembeka okungcono kwiisekethe ze-SiC / IGBT kodwa zibonelela ngeendleko ezingcono, ukoyisa imiqobo yexabiso ekusetyenzisweni okubanzi kweefilim capacitors.
Njengovulindlela wezoshishino, i-YMIN ibandakanyeke ngokunzulu kwintsimi ye-capacitor ngaphezu kweminyaka engama-20. I-capacitors yayo ephezulu ye-voltage isetyenziswe ngokuzinzileyo kwiindawo eziphakamileyo ezifana ne-OBC yebhodi, iimfumba zokutshaja amandla amatsha, ii-photovoltaic inverters, kunye neerobhothi zezoshishino iminyaka emininzi. Esi sizukulwana esitsha seemveliso zefilimu capacitor sombulula imingeni eyahlukahlukeneyo ekulawuleni inkqubo yokuvelisa ifilimu ye-capacitor kunye nezixhobo, sigqibe ukuthembeka kwesatifikethi kunye namashishini ahamba phambili ehlabathi, kwaye sifezekise isicelo esikhulu, esibonisa ukuthembeka kwemveliso kubathengi abakhulu. Kwixesha elizayo, i-YMIN iya kuphucula ukuqokelela kwayo kwexesha elide lobugcisa ukuxhasa uphuhliso olukhawulezayo lweshishini elitsha lamandla kunye nokuthembeka okuphezulu kunye neemveliso ze-capacitor ezingabizi kakhulu.
