Ma capacitor a filimu ya DC-link ya Inverter omwe amasinthidwa mphamvu
1. Kuphimba chipolopolo chachitsulo, kulowetsedwa kwa utomoni wouma;
2. Ingagwiritsidwe ntchito m'malo ovuta
3. Kudalirika kwambiri
4. Kutha kudzichiritsa
5. Ma capacitor a filimu nawonso amakhala ndi moyo wautali kuposa ma capacitor a electrolytics ndi zina zotero.

Ma Capacitors a DC Bus a IGBT-Based Converters mu Traction Apparatus
DC basi capacitor DMJ-MC mndandanda
Ma capacitor a filimu yachitsulo amapangidwa ndi mafilimu awiri achitsulo okhala ndi filimu yapulasitiki ngati dielectric.
Chitsulo chopyapyala kwambiri cha aluminiyamu (~ 0.03 μm[2]) choyikidwa mu vacuum chimayikidwa mbali imodzi kapena zonse ziwiri kuti chikhale ngati ma electrode.

Ma Capacitors a Magalimoto Osakanikirana ndi Amagetsi Opangidwa ndi Kapangidwe Kakang'ono
1. Phukusi la pulasitiki, losindikizidwa ndi utomoni wa epoxy wofewa, zingwe zamkuwa, kukula kosinthidwa
2. Kukana ku filimu ya polypropylene yachitsulo yodzichiritsa yokha, yamagetsi okwera
3. ESR yotsika, kuthekera kogwiritsa ntchito mphamvu yamagetsi ya ripple yambiri
4. Low ESR, imachepetsa bwino mphamvu yamagetsi yobwerera
5. Mphamvu yayikulu, kapangidwe kakang'ono

Filimu yodzichiritsa yokha Power capacitor bank yothandiza kunyamula njanji
Mndandanda wa DKMJ-S wapamwamba ndi mtundu watsopano wa DKMJ-S. Pa mtundu uwu, timagwiritsa ntchito chivundikiro cha mbale chopangidwa ndi aluminiyamu kuti chigwire bwino ntchito. Ngati capacitor ili ndi malo osiyana oikira, ndikuyikidwa pamalo otseguka, iyi ndi yabwino.

Chojambulira cha PCB cholumikizira ma pin terminal cha mapulogalamu apamwamba kwambiri / amphamvu kwambiri
Mndandanda wa DMJ-PS wapangidwa ndi ma pin lead awiri kapena anayi, oyikidwa pa bolodi la PCB. Poyerekeza ndi ma electrolytic capacitors, mphamvu yayikulu komanso moyo wautali zimapangitsa kuti ikhale yotchuka masiku ano.

Capacitor yapamwamba ya polypropylene ya Metallized mu ntchito zamagetsi amphamvu kwambiri
Ma capacitor a CRE Polypropylene power film capacitors nthawi zambiri amagwiritsidwa ntchito pamagetsi amphamvu kwambiri chifukwa cha mphamvu yawo yayikulu ya dielectric, kuchuluka kochepa kwa volumetric, komanso dielectric constant yotsika kwambiri (tanδ). Ma capacitor athu amakumananso ndi kutayika kochepa ndipo, kutengera zomwe zimagwiritsidwa ntchito, amatha kupangidwa ndi malo osalala kapena amdima.

Kapangidwe ka Power Film Capacitor ka Galimoto Yamagetsi
1. Phukusi la pulasitiki, losindikizidwa ndi utomoni wa epoxy wofewa, zingwe zamkuwa, kukula kosinthidwa
2. Kukana ku filimu ya polypropylene yachitsulo yodzichiritsa yokha, yamagetsi okwera
3. ESR yotsika, kuthekera kogwiritsa ntchito mphamvu yamagetsi ya ripple yambiri
4. Low ESR, imachepetsa bwino mphamvu yamagetsi yobwerera
5. Mphamvu yayikulu, kapangidwe kakang'ono

Kapepala ka filimu ya DC yolumikizidwa ndi PCB yopangidwira inverter ya PV
1. Kuphimba chipolopolo cha pulasitiki, kulowetsedwa kwa utomoni wouma;
2. zingwe zokhala ndi mapini, kapangidwe kakang'ono, zosavuta kukhazikitsa;
3. ESL ndi ESR yotsika;
4. Kugunda kwamphamvu kwamphamvu.
5. Chitsimikizo cha UL;
6. Kutentha kwakukulu kogwira ntchito: -40 ~ +105℃
-
Ma capacitor opanga mafilimu atsopano amphamvu kwambiri
Cholinga cha DC-link capacitor ndikupereka mphamvu ya DC yokhazikika, kuchepetsa kusinthasintha chifukwa inverter nthawi zina imafuna mphamvu yolemera.
CRE DC link capacitor imagwiritsidwa ntchito paukadaulo wouma womwe umaonetsetsa kuti ikugwira ntchito bwino, ikugwira ntchito bwino, ikukhala nthawi yayitali ndi zina zotero.

Capacitor Yogwira Ntchito Kwambiri ya Magalimoto Amagetsi (EVs) ndi Magalimoto Amagetsi Osakanikirana (HEVs) (DKMJ-AP)
Chitsanzo cha Capacitor: DKMJ-AP Series
Mawonekedwe:
1. Ma electrode a Copper Flat
2. Phukusi la Pulasitiki Lotsekedwa ndi Utomoni Wouma
3. Kuchuluka Kwambiri mu Kukula Kochepa Kwathupi
4. Kukhazikitsa Kosavuta
5. Kukana Mphamvu Yaikulu ya Voteji
6. Kutha Kudzichiritsa
7. ESL Yotsika ndi ESR
8. Yokhoza Kugwira Ntchito Pogwiritsa Ntchito Mphamvu Yaikulu Yophulika
Mapulogalamu:
Zapadera pa Magalimoto Amagetsi (ma EV) ndi Magalimoto Amagetsi Osakanikirana (ma HEV)
