[Buku Lotsogolera Kusankha] Kodi Mungatani Kuti Muyeretse Mphamvu Yaikulu ndi Moyo Wautali mu Ma OBC Ang'onoang'ono? Kusanthula kwa Ma Capacitors Amphamvu a YMIN LKD

Chiyambi

Mu mapangidwe a 800V OBC ndi DC-DC, kusankha ma capacitor kwakhala chinthu chofunikira kwambiri chomwe chimakhudza kuchuluka kwa mphamvu, magwiridwe antchito, komanso kudalirika. Ma capacitor a aluminiyamu achikhalidwe, chifukwa cha kukula kwawo kwakukulu, moyo wawo waufupi, komanso mawonekedwe ake otsika a frequency, sangakwaniritse zofunikira izi. Nkhaniyi iwunikanso ubwino wa magwiridwe antchito a ma capacitor a aluminiyamu a YMIN Electronics a LKD series high-voltage aluminium electrolytic capacitors pankhani ya miniaturization, high ripple current resistance, komanso moyo wautali, kupatsa mainjiniya chitsogozo chosankha.

OBC - YMIN Aluminium Electrolytic Capacitor LKD Yankho

Chifukwa cha kuchuluka kwa zipangizo za SiC komanso kuchuluka kwa ma switching frequency, ma capacitor mu ma OBC modules ayenera kupirira ma ripple currents apamwamba komanso kupsinjika kwa kutentha. Ma capacitor a aluminiyamu achikhalidwe amatha kutenthedwa kwambiri ndipo amakhala ndi moyo waufupi. Kupeza capacitance yayikulu, kukana ma voltage ambiri, ESR yochepa, komanso moyo wautali mu kukula kochepa kwakhala vuto lalikulu pakupanga kwa OBC.

- Kusanthula Kwaukadaulo kwa Chifukwa Chachikulu -

Chifukwa chachikulu cha vutoli chili mu zofooka za zipangizo ndi njira za ma capacitor achikhalidwe:

Ma electrolyte wamba amasinthasintha mosavuta kutentha kwambiri, zomwe zimapangitsa kuti capacitance ichepe komanso kuti ESR iwonjezereke;

Mapangidwe a nyumba zachikhalidwe ali ndi mphamvu zochepa, zomwe zimapangitsa kuti zikhale zovuta kulinganiza mphamvu yamagetsi ndi mphamvu yamagetsi;

Kusadalirika kokwanira kwa kutseka kumabweretsa kutayikira m'malo ogwedezeka.

Magawo ofunikira monga kuchuluka kwa capacitance, ESR @ 100kHz, rated ripple current @ 105°C, ndi moyo wa chipangizocho zimakhudza mwachindunji kupambana kwa chipangizocho.

- Mayankho a YMIN ndi Ubwino wa Njira -

Mndandanda wa YMIN LKD umagwiritsa ntchito njira zingapo zatsopano:

1. Chojambula cha electrode chokhala ndi kuchuluka kwakukulu: Chimawonjezera mphamvu yamagetsi pa voliyumu iliyonse, kuchepetsa voliyumu ndi 20% mpaka 40% poyerekeza ndi zinthu zofanana;

2. Electrolyte yotsika kwambiri: Imachepetsa bwino ESR ndipo imapangitsa kuti ma ripple azitha kupirira mosavuta;

3. Kulimbitsa kutseka ndi kapangidwe kolimba kosaphulika: Kupambana mayeso okana kugwedezeka a 10G, kuchotsa zoopsa zotayikira;

4. Kapangidwe ka mphamvu yamagetsi yokwera: Imapereka mphamvu yamagetsi yokwanira, yoyenera kugwiritsidwa ntchito pamapulatifomu a 800V ndi kupitirira apo.

Kutsimikizira ndi Kusankha Deta Yodalirika

Monga momwe tikuonera, mndandanda wa LKD umachita bwino kwambiri kuposa zinthu wamba pankhani ya kukula, ESR, kukana kwa ripple, komanso moyo wautali.

- Zochitika Zogwiritsira Ntchito ndi Ma Model Ovomerezeka - Mndandanda wa LKD ndi woyenera: Kusefa kwa OBC PFC boost circuit output; Thandizo la DC-Link ndi buffering; ndi kusefa kwa DC-DC.

- Ma Model Ovomerezeka -

LKD 700V 150μF 25×50: Yoyenera makina a 1200V DC-Link;

LKD 500V 330μF 25×50: Yoyenera kusefa kwamphamvu kwambiri mumakina a 800V;

LKD 450V 330μF: Kuwerengera kukula ndi mphamvu zomwe zimafunika;

LKD 500V 220μF: Yoyenera kugwiritsidwa ntchito m'malo ochepa kwambiri.

Mapeto

Mndandanda wa YMIN wa LKD, kudzera mu zipangizo ndi mapangidwe atsopano, umakwaniritsa bwino zofunikira zodalirika komanso zazing'ono za ma capacitor mu ntchito zamagetsi amphamvu, zamafupipafupi, komanso kutentha kwambiri. Wakhala capacitor wosankhidwa kwambiri pamapulojekiti a OBC m'makampani ambiri otsogola a magalimoto. Timathandizira mapulogalamu a zitsanzo ndi chithandizo chaukadaulo, kuthandiza mainjiniya kukhazikitsa mapulojekiti mwachangu.
