Incazelo emfushane:

1. Iphakheji yepulasitiki, evalwe nge-epoxy resin enobungani nemvelo, ama-lead ethusi, ubukhulu obufanele

2. Ukumelana nefilimu ye-polypropylene enensimbi ephezulu, eyaziphilisa ngokwayo

3. I-ESR ephansi, ikhono lokuphatha ugesi oluphezulu

4. I-ESR ephansi, yehlisa ngempumelelo i-voltage ebuyela emuva

5. Umthamo omkhulu, isakhiwo esincane

Uchungechunge lwe-DKMJ-AP

Ama-capacitor amafilimu anamandla athuthukisiwe anobuchwepheshe bokuziphilisa obulawulwayo angenye yezixazululo ze-elekthronikhi zamandla onjiniyela be-EV ne-HEV abangathembela kuzo ukuze bahlangabezane nosayizi oqinile, isisindo, ukusebenza, kanye nezindinganiso zokuthembeka ezingenangozi neze zokwehluleka kule makethe edinga kakhulu.

Ama-capacitor efilimu enamandla akwazi ukuletha izixazululo zokuklama ezithembekile zama-EV nama-HEV kumele ahlangabezane nemingcele ethile ethile mayelana nezinto zefilimu ezenziwe ngensimbi, ukucubungula, kanye nokuklama.

Isici

Intuthuko esimeme isibe ngumqondo obalulekile futhi osakazeke yonke indawo enkathini yanamuhla. Ikakhulukazi, embonini yamandla, izixazululo zamandla ahlanzekile, avuselelekayo zithatha indawo yezindlela zendabuko ezisekelwe ku-oyela. Njengoba i-EV ne-HEV kuyimakethe ekhulayo, ama-inverter kudingeka abe nosayizi omncane, ukuminyana kwamandla okuphezulu, i-wide bandgap (WGB) kanye nokwehluleka okungekho nhlekelele ukuze kufakwe esikhundleni senjini yokushisa yangaphakathi yendabuko (ICE). Ngenxa yalokho, i-capacitor yefilimu eyenziwe ngensimbi iyimfuneko ebalulekile ye-EV ne-HEV yesikhathi esizayo ukuze kuhlangatshezwane nalezi zindlela zemakethe.

I-capacitor yefilimu enensimbi e-CRE inesici sokuziphilisa, ikhono lokuvimbela ukwehluleka okubi kakhulu lapho kwenzeka iphutha langaphakathi. Ifilimu ye-dielectric ku-capacitor yethu imbozwe ngezinto zensimbi ezifakwa nge-vacuum futhi zinobukhulu obungama-nanometer ayishumi nambili kuphela. Uma kukhona iphuzu elibuthakathaka noma ukungcola ku-dielectric, kuzophuka. Amandla akhishwa yi-arc discharge ekuqhekekeni azokwanela ukuhwamuka ungqimba lwensimbi oluzungezile, ahlukanise iphutha futhi aphulukise ngempumelelo i-capacitor ukuze kugcinwe ukusebenza.

Ngalobu buchwepheshe bokuziphilisa, ama-capacitor ethu efilimu enziwe ngensimbi ayasebenza ezidingweni eziningi zemakethe futhi ayakwazi ukufeza izidingo ze-elekthronikhi ezithuthukisiwe okuhlanganisa nalezo zama-inverters asetshenziswa ku-EV kanye ne-HEV. Anesikhathi eside sokuphila kanye nokuthembeka okusebenzayo ngaphandle kokwehluleka okukhulu. Ngaphezu kwezinzuzo ezibangelwa yisici sokuziphilisa, ama-capacitor ethu nawo mancane ngobukhulu futhi anomthamo omkhulu. Angafakwa kalula futhi angamelana ne-voltage ephezulu.

Ama-capacitor efilimu anensimbi asetshenziswa yimiklamo ye-patent ye-CRE. Avame ukufakwa i-resin eyomile, aboshwe yi-Myra tape bese evalwa ngegobolondo lensimbi noma lepulasitiki. Umklamo we-patent uzoletha izinzuzo ezahlukahlukene okuhlanganisa ukulinganisela amandla kagesi kanye ne-inductance, akukho ukwanda kokushisa okubalulekile, insimu kagesi ephezulu kanye nezindleko zokukhiqiza eziphansi. Ama-capacitor bobbin amaningi angafakwa ku-solder esakhiweni sebha yebhasi ukuze anikeze amanani aphansi okuzilawula angasetshenziswa ukunciphisa i-over-voltage ngesikhathi sokushintsha.

Njengenye yezimpendulo zendlela yamandla ahlanzekile kanye nentuthuko esimeme, imakethe ye-EV kanye ne-HEV kulindeleke ukuthi ikhule njalo futhi ekugcineni ithathe indawo yamamodeli e-ICE. Ama-capacitor efilimu anensimbi e-Wuxi CRE azoba yisisombululo esisebenzayo, esithembekile nesiholayo sokukhiqiza kwakho kwesikhathi esizayo.
