Ihashe elilungileyo lifanelwe yi-saddle elungileyo! Ukunyusa ngokupheleleyo izibonelelo zezixhobo ze-SIC, kuyayimfuneko ukudibanisa inkqubo yesekethe kunye namandla afanelekileyo. Ukusuka kulawulo oluphambili kwizithuthi zombane ukuya kunkcenkceshela amandla amatsha e-Photovoltaic enjengee-fotovol, i-cancitiors yefilimu ngokuthe ngcembe ngokuthe ngcembe, kwaye intengiso ineemveliso zexabiso eliphezulu.
Kutshanje, uShanghai Youbming Elewkhi ye-elektroniki Coung., I-LTD.. Zikwanceda ukujongana nemiceli mngeni yokuqikelela, ukuthembeka, ubuncinci, kunye neendleko kwiinkqubo ze-SIC.
I-filkocitors iphumelele phantse i-90% ingena kwi-90% kwizicelo eziphambili zokuqhuba. Kutheni i-sic kunye i-Igbt ifuna?
Kwiminyaka yakutshanje, kunye nophuhliso olukhawulezileyo lwamashishini atsha anjengokugcinwa kwamandla, ukutshaja, kunye nezithuthi zombane (i-EVs), imfuno ye-DC-Cons) eyandayo ngokukhawuleza. Ukubeka nje, i-DC-NCINCITOTOTITITORS ASTERS KWI-Buffers kwisekethe, efumana imijelo ephezulu ye-pulse esuka esiphelweni kunye ne-volting yebhasi, ngaloo ndlela ukhusela i-Igbt kunye nefuthe le-Ig
Ngokwesiqhelo, ama-Alumnum Akitolytic asetyenziswa kwizicelo zenkxaso ye-DC. Nangona kunjalo, ngevoti yebhasi yezithuthi zamandla amatsha anyukayo ukusuka kwi-400v ukuya kwi-800v ukuya kwi-800v kunye neenkqubo zefotovoltaic kunye ne-2000v kunye nemfuno yeefilimu ezenyuka kakhulu.
Idatha ibonisa ukuba ngonyaka we-2022, umthamo ofakiweyo we-thesvers wombane ombane ngokusekwe kwi-DC-IchieCitCitcitars ifikelele kwi-5.11117 yezigidi, i-accounting ye-88.7% yendawo efakwe kuyo i-loures ye-elektroniki. Ukulawulwa kweNkampani yoLawulo lwe-FIDI, iTesa, itekhnoloji ye-InOvance, i-Nidec, kunye neWiran amandla onke asebenzisa amandla e-DC-Inki kwi-Andssies yabo efakelweyo ukuya kuthi ga kwi-82.9%. Oku kubonisa ukuba amachaphaza efilimu athathe indawo yokungasebenzi kwamandla e-electrolytical njengeyona ndawo iphambili kwimarike yombane.
Kungenxa yokuba owona mkhulu wokuchasana ne-voltage ye-Aluminium ye-Aluminium ye-elektrolytic imalunga ne-630V. Kumbane ophezulu kunye nokusetyenziswa okuphezulu kwamandla ngaphezulu kwe-700v, amandla amaninzi e-elekitic, kufuneka adibane nothotho lweemfuno zokusetyenziswa, okuzisa ilahleko eyongezelelweyo yokusetyenziswa, i-Bom indleko, kunye nemicimbi yokuxhomekeka.
Iphepha lophando elivela kwiDyunivesithi yaseMalaysia libonisa ukuba amachaphaza e-elektrolytical asetyenziswe kwikhonkco le-DC le-silicion Igbt harhers, kodwa ukuhlangula kwe-voltage kunokwenzeka ngenxa yokumelana namandla aphezulu aphezulu. Xa kuthelekiswa nezisombululo ze-silicon-esekwe kwi-selicon esekwe kwi-Igbt, i-Moskiets ye-SIC itshintshe i-frequeges, kukhokelela kwi-voltage ephezulu ye-voltage kwikhonkco le-DC le-DC ye-Bridgeents. Oku kunokukhokelela ekulahlekeni kwendlela yokusebenza kwefowuni okanye ukonakala, njengendawo yokuhlala ye-Eicrolylik i-4khz, akwanelanga ukufunxa i-ripple engaphakathi ye-SOSFET.
Ke ngoko, kwizicelo zeDC ezineemfuno zokuthembeka okuphezulu, ezinje nge-interter yombane ye-interv kunye ne-potovoltaic, i-phothivoltaic, i-cancitiors idla ngokuthandwa. Xa kuthelekiswa ne-Aluminum ye-Aluminium ye-Aluminily ye-Aluminilytic, izibonelelo zawo zentsebenzo zibandakanya ukumelana nokunganyangwa kwee-voltage, i-ESR ephantsi, ukungasebenzi kakuhle, kunye nokusebenza okuzinzileyo, kunye nokuphila okusemandleni, okwenza i-Lifepan, kwaye isebenze ngendlela ethembekileyo yokuchasana nenkqubo ethembekileyo.
Ukongeza, ukusebenzisa amachaphaza efilimu kwinkqubo inokuphinda ixhase rhoqo, impahla elahlekileyo ye-SIC ye-MOSFETS, ukunciphisa ubukhulu kunye nobunzima bezinto ezidlulayo (izibonda, ii-caplowers) kwinkqubo. Ngokutsho kweWollpoloed Searvar, i-Igbt esekwe kwi-7kww i-Igbt ifuna i-Aluminum ye-Aluminum ye-Aluminium, ngelixa i-Inc ye-Inc ye-8KW idinga ii-capacitors ezi-8, zinciphisa kakhulu indawo yePCB.

Ukujongana neemfuno zentengiso engxamisekileyo, y kwaphela i-MDR ye-MDP yoluhlu lwe-DC i-DC ye-DC yefilimu. Ukusebenzisa iinkqubo zoveliso zoMveliso kunye nezinto ezikumgangatho ophezulu, ezi zixhobo zihambelana ngokugqibeleleyo neemfuno zokusebenza ze-SIC ye-SIC ye-SIC ye-SICOFETS kunye ne-Igbts esekwe kwi-Silicon kwiinkokheli zamandla e-semicondcuctor ezifana ne-inficonds.
I-WDP's MDP ye-MDR kunye ne-MDR Cering Price Chicictions ineempawu ezininzi ezibonakalayo: Ukunganyangeki kokuthethwa kwenqanaba elinezantsi (i-ESR), i-voltage ephezulu kakhulu, ukuvuza okuphantsi kozinzo.
Okokuqala, iifilimu zefilimu ze-YMS zibonisa uyilo olusezantsi, zinciphise uxinzelelo lwevolthi ngexesha lokutshintsha kwe-SIC MOSFETS kunye ne-Igbts esekwe kwi-silicon, ngaloo ndlela kuncitshiswe i-Canector kunye nokuphucula ukusebenza kwenkqubo. Ukongeza, ezi candlacitors zine-voltage ephezulu yexesha, enakho ukupapashwa kweemeko eziphezulu zeevolimu kunye nokuqinisekisa ukusebenza kwenkqubo ezinzileyo.
I-MDP kunye ne-MDR ye-WMS yeefilimu ze-YMS ibonelela nge-5iuf-150uf kunye ne-50000-1500v kunye ne-350V-2200V-2200V, ngokwahlukeneyo.
Okwesibini, iifilicial zefilimu ze-YMn zine-leakie ephantsi yokuvuza kunye nokuzinza kobushushu obuphezulu. Kwimeko yeenkqubo zolawulo lombane ezisebenza ngemoto, eziqhelekileyo zinamandla aphezulu, ukuvelisa ubushushu kunokuchaphazela kakhulu i-Lifepan kunye nokuthembeka kwee-ficcocitors. Ukujongana nale nto, i-MDP kunye noluhlu lwe-MDR lubandakanya izixhobo ezisemgangathweni eziphezulu kunye neendlela zokuqhubela phambili kwemveliso yokuyila ubume obuphumeyo be-candlacious. Oku kuqinisekisa ukusebenza okuzinzileyo kwanakwindawo ephezulu yobushushu, ethintela ukuncipha kwexabiso le-Caceciow okanye ukungaphumeleli ngenxa yokuphakama kweqondo lobushushu. Ngaphaya koko, aba banamachaphaza banexesha elinde, babonelela ngenkxaso ethembekileyo yeenkqubo ze-elektroniki.
Okwesithathu, i-MDP kunye ne-MDR Cestan Secectior kwi-ymin i-Ymin ubungakanani obukhulu kunye nokuxinana kwamandla okuphakathi. Umzekelo, kwiinkqubo ze-800V zenkqubo ye-Drive, le nkqubo kukusebenzisa izixhobo ze-SIC ukunciphisa ubungakanani be-camocitors kunye nezinye izinto eziphathekayo, ngaloo ndlela kukhuthaza ubuninzi bee-elektroniki. I-Ymin isebenzise itekhnoloji yokufumana ifilimu yefilimu, engaphumeleli kuphela ukudityaniswa kwenkqubo kunye nokusebenza kakuhle kodwa kunciphisa ubungakanani benkqubo nobunzima, ekwandiseni izixhobo kunye nokuguquguquka kwezixhobo.
Ngokubanzi, i-DC-Confic ka-YC-Inki ye-DC-Inki yeFilit ibonelela ngophuculo lwe-30% kwi-DV / DT ikwazisa amandla kunye nokunyuka kwe-30% e-Winkepan kuthelekiswa nezinye ii-filkoti. Oku akunikezeli nje kuphela ukuthembeka okungcono kwi-SIC / i-Igbt kodwa ikwabonelela ngendleko ezingcono zokuxabisa, ukoyisa izithintelo zamaxabiso ekusebenziseni amachaphaza eefilimu.
Njengoovulindlela beshishini, ymin ibandakanyeke ngokunzulu kwicandelo leCapacitor iminyaka engaphezu kwama-20. Amandla ayo aphezulu e-Voltiage isetyenziswe ngokufanelekileyo kwimimandla ekuphela efana ne-OBC ye-OBC, i-PhotoSwolta yamandla amatsha, iifotovoltaic amantshontsho, kunye neerobhothi zemveliso iminyaka emininzi. Esi sizukulwana sitsha seemveliso zefilimu isombulula imiceli mngeni yenkqubo yenkqubo yefilimu kunye nezixhobo, igqibe isiqinisekiso sokuthembeka ngamashishini ehlabathi asehlabathini, kwaye ifezekisile isicelo esikhulu, sibonisa ukuthembeka kwemveliso kubathengi abakhulu. Kwixa elizayo, ymin izakunyusa ukuqokelelwa kwexesha elide ukuba ixhase ukuphuculwa ngokukhawuleza kweshishini elitsha lamandla anokuthembeka okuphezulu kunye neemveliso zexabiso elinamandla.
