Pokambilana za zatsopano ndi kusintha kwa magetsi a magalimoto amagetsi, nthawi zambiri zimayikidwa pazigawo zazikuluzikulu monga chida chachikulu chowongolera ndi zipangizo zamagetsi, pamene zida zothandizira monga capacitors zimakonda kulandira chidwi chochepa. Komabe, zigawo zothandizira izi zimakhudza kwambiri momwe dongosolo lonse likuyendera. Nkhaniyi ifufuza momwe ma capacitor amafilimu a YMIN amagwirira ntchito pama charger aku board ndikuwunika kusankha ndi kugwiritsa ntchito ma capacitor pamagalimoto amagetsi.

Mwa mitundu yosiyanasiyana ya capacitors,aluminium electrolytic capacitorsali ndi mbiri yayitali ndipo atenga udindo waukulu pazamagetsi zamagetsi. Komabe, ndikusintha kwa zofunikira zaukadaulo, zofooka za electrolytic capacitors zawonekera kwambiri. Zotsatira zake, njira ina yabwino kwambiri - ma capacitor amafilimu - yawonekera.

Poyerekeza ndi ma electrolytic capacitor, ma capacitor amakanema amapereka maubwino ofunikira pakupirira kwamagetsi, kutsika kofanana ndi kukana (ESR), kusakhala ndi polarity, kukhazikika kwamphamvu, komanso moyo wautali. Izi zimapangitsa kuti ma capacitor amakanema azikhala otsogola pakupanga makina osavuta, kukulitsa luso lapano, ndikupereka magwiridwe odalirika pansi pazovuta zachilengedwe.

Table: Kufananiza ubwino wamafilimu capacitorsndi aluminium electrolytic capacitors

Poyerekeza machitidwe a mafilimu opangira mafilimu ndi malo ogwiritsira ntchito magalimoto amagetsi, zikuwonekeratu kuti pali kugwirizana kwakukulu pakati pa awiriwa. Momwemonso, ma capacitor a filimu mosakayikira ndi omwe amawakonda kwambiri pakupanga magetsi pamagalimoto amagetsi. Komabe, kuti awonetsetse kuti ali oyenerera kugwiritsa ntchito magalimoto, ma capacitor awa ayenera kukwaniritsa miyezo yolimba yamagalimoto, monga AEC-Q200, ndikuwonetsa magwiridwe antchito odalirika pansi pamikhalidwe yovuta kwambiri. Malingana ndi zofunikirazi, kusankha ndi kugwiritsa ntchito ma capacitors kuyenera kutsatira mfundozi.

Dongosolo la OBC (On-Board Charger) nthawi zambiri limakhala ndi zigawo zikuluzikulu ziwiri: chowongolera chomwe chimasintha magetsi a mains a AC kukhala DC, ndi chosinthira magetsi cha DC-DC chomwe chimapanga magetsi ofunikira a DC kuti azilipiritsa. Munjira iyi,mafilimu capacitorspezani ntchito m'magawo angapo, kuphatikiza:

●Kusefa kwa EMI
●DC Link
●Zosefera Zotulutsa
●Resonant Tank

02 Zochitika zogwiritsa ntchito ma capacitor amakanema mu OBC

YMINimapereka zinthu zingapo zopangira filimu capacitor yoyenera DC-Link ndi zosefera zotulutsa. Makamaka, zinthu zonsezi ndi zovomerezeka za AEC-Q200 zamagalimoto. Kuphatikiza apo, YMIN imapereka zitsanzo zapadera zomwe zimapangidwira kutentha kwambiri komanso chinyezi chambiri (THB), zomwe zimapatsa opanga kusinthasintha kwakukulu pakusankha zigawo.

DC-Link Capacitors

Mu dongosolo la OBC, DC-Link capacitor ndiyofunikira pakuthandizira ndi kusefa pakati pa rectifier circuit ndi DC-DC converter. Ntchito yake yayikulu ndikuyamwa mafunde othamanga kwambiri pabasi ya DC-Link, kuletsa kugunda kwamphamvu kwamagetsi kudutsa DC-Link ndikuteteza katunduyo kuti asapitirire.

Makhalidwe achilengedwe a ma capacitor amafilimu-monga kulekerera kwamagetsi kwamagetsi, mphamvu yayikulu, komanso kusakhala ndi polarity-amawapangitsa kukhala abwino pazosefera za DC-Link.

YMIN paMDP (H)mndandanda ndi chisankho chabwino kwambiri cha DC-Link capacitors, chopereka:

Ma Capacitors Osefera Zotulutsa

Kuti mukweze kuyankha kwakanthawi kakutulutsa kwa OBC's DC, mphamvu yayikulu, yotsika ya ESR yotulutsa fyuluta capacitor ikufunika. YMIN amaperekaMDPma capacitors otsika kwambiri a DC-Link, omwe amakhala:

Zogulitsazi zimapereka magwiridwe antchito apamwamba, kudalirika, komanso kusinthika pamagalimoto omwe amafunikira, kuwonetsetsa kuti OBC ikugwira ntchito bwino komanso yokhazikika.
