Pokambirana za zatsopano ndi kusintha kwa makina opangira magetsi m'magalimoto amagetsi, nthawi zambiri chidwi chimayikidwa pa zigawo zazikulu monga gawo lalikulu lowongolera ndi zida zamagetsi, pomwe zigawo zothandizira monga ma capacitor nthawi zambiri sizimalandira chidwi chochuluka. Komabe, zigawo zothandizirazi zimakhudza kwambiri magwiridwe antchito onse a makinawo. Nkhaniyi ifotokoza momwe ma capacitor a YMIN amagwiritsidwira ntchito m'ma charger omwe ali mkati mwa galimoto ndikuwunika kusankha ndi kugwiritsa ntchito ma capacitor m'magalimoto amagetsi.

Pakati pa mitundu yosiyanasiyana ya ma capacitor,ma capacitor a electrolytic a aluminiyamuali ndi mbiri yakale ndipo akhala ndi udindo waukulu m'munda wa zamagetsi zamagetsi. Komabe, chifukwa cha kusintha kwa zofunikira zaukadaulo, zofooka za ma capacitor amagetsi zawonekera kwambiri. Zotsatira zake, njira ina yabwino kwambiri—ma capacitor opanga mafilimu—yatulukira.

Poyerekeza ndi ma capacitor a electrolytic, ma capacitor a filimu amapereka ubwino waukulu pankhani ya kupirira kwa voltage, kukana kofanana ndi kotsika (ESR), kusasinthasintha kwa polarity, kukhazikika kwamphamvu, komanso moyo wautali. Makhalidwe amenewa amapangitsa ma capacitor a filimu kukhala abwino kwambiri pakupangitsa kuti kapangidwe kake kakhale kosavuta, kukulitsa mphamvu ya ripple current, komanso kupereka magwiridwe antchito odalirika kwambiri m'malo ovuta.

Tebulo: Ubwino woyerekeza wa magwiridwe antchitoma capacitor a filimundi ma capacitor a electrolytic a aluminiyamu

Poyerekeza momwe ma capacitor a mafilimu amagwirira ntchito ndi malo ogwiritsira ntchito magalimoto amagetsi, n'zoonekeratu kuti pali kugwirizana kwakukulu pakati pa awiriwa. Motero, ma capacitor a mafilimu mosakayikira ndi omwe amakondedwa kwambiri pakugwiritsa ntchito magetsi pamagalimoto amagetsi. Komabe, kuti atsimikizire kuti ndi oyenera kugwiritsidwa ntchito pamagalimoto, ma capacitor awa ayenera kukwaniritsa miyezo yokhwima yamagalimoto, monga AEC-Q200, ndikuwonetsa magwiridwe antchito odalirika pansi pa mikhalidwe yovuta kwambiri. Kutengera ndi zofunikira izi, kusankha ndi kugwiritsa ntchito ma capacitor kuyenera kutsatira mfundo izi.

Dongosolo la OBC (On-Board Charger) nthawi zambiri limakhala ndi zigawo ziwiri zazikulu: dera lokonzanso lomwe limasintha mphamvu ya main ya AC kukhala DC, ndi chosinthira mphamvu cha DC-DC chomwe chimapanga magetsi ofunikira a DC kuti ayambe kuchajidwa. Munjira iyi,ma capacitor a filimupezani ntchito m'magawo angapo ofunikira, kuphatikizapo:

●Kusefa kwa EMI
●DC-Link
●Kusefa Zotuluka
●Thanki Yonyezimira

02 Zochitika za kugwiritsa ntchito ma capacitor a filimu mu OBC

YMINimapereka mitundu yosiyanasiyana ya zinthu zopangira mafilimu zoyenera kugwiritsa ntchito DC-Link ndi zosefera zotulutsa. Chodziwika bwino n'chakuti, zinthu zonsezi zili ndi satifiketi ya AEC-Q200 automotive grade. Kuphatikiza apo, YMIN imapereka mitundu yapadera yopangidwira malo otentha kwambiri komanso chinyezi chambiri (THB), zomwe zimapatsa opanga mapulogalamu kusinthasintha kwakukulu pakusankha zigawo.

Ma Capacitor a DC-Link

Mu dongosolo la OBC, capacitor ya DC-Link ndi yofunika kwambiri pothandizira ndi kusefa pakati pa dera lokonzanso magetsi ndi chosinthira magetsi cha DC-DC. Ntchito yake yayikulu ndikuyamwa ma pulse currents apamwamba pa basi ya DC-Link, kuteteza ma pulse voltage apamwamba kudutsa impedance ya DC-Link ndikuteteza katundu ku overvoltage.

Makhalidwe enieni a ma capacitor a filimu—monga kulekerera kwa magetsi ambiri, capacitance yayikulu, komanso kusakhala ndi polarity—amawapangitsa kukhala abwino kwambiri pa ntchito zosefera za DC-Link.

YMIN'sMDP(H)Mndandanda ndi chisankho chabwino kwambiri cha ma capacitor a DC-Link, omwe amapereka:

Zosefera Zotulutsa

Kuti muwonjezere mphamvu ya yankho la OBC's DC output, pamafunika capacitor yotulutsa fyuluta yokhala ndi capacitance yayikulu komanso yotsika ya ESR. YMIN imaperekaMDPMa capacitor a filimu a DC-Link okhala ndi mphamvu zochepa, omwe ali ndi:

Zogulitsazi zimapereka magwiridwe antchito abwino kwambiri, kudalirika, komanso kusinthasintha pakugwiritsa ntchito magalimoto ovuta, zomwe zimaonetsetsa kuti OBC ikugwira ntchito bwino komanso mokhazikika.
