[Zosankha Zosankha] Momwe Mungasankhire Kuthamanga Kwambiri ndi Moyo Wautali mu Ma OBC Ochepa? Kusanthula kwa YMIN LKD High-Voltage Capacitors

Mawu Oyamba

Mu mapangidwe a 800V OBC ndi DC-DC, kusankha kwa capacitor kwakhala chinthu chofunikira kwambiri chokhudza kachulukidwe ka mphamvu, kuchita bwino, komanso kudalirika. Ma capacitor amtundu wa aluminiyamu electrolytic capacitor, chifukwa cha kukula kwawo kwakukulu, moyo waufupi, komanso mawonekedwe otsika kwambiri, sangathe kukwaniritsa izi. Nkhaniyi ifotokoza za ubwino wa YMIN Electronics 'LKD mndandanda wa high-voltage aluminiyamu electrolytic capacitors malinga ndi miniaturization, kukana kwakukulu kwaposachedwa, komanso moyo wautali, kupatsa mainjiniya kalozera wosankha.

OBC - YMIN Aluminium Electrolytic Capacitor LKD Solution

Ndi kuchuluka kwa zida za SiC komanso kuchulukitsidwa kwa ma frequency, ma capacitor mu ma module a OBC amayenera kupirira mafunde apamwamba komanso kupsinjika kwamafuta. Ma aluminium electrolytic capacitor wamba amatha kutentha kwambiri ndipo amakhala ndi moyo wautali. Kupeza luso lapamwamba, kukana kwamagetsi, kutsika kwa ESR, ndi moyo wautali mu kukula kophatikizana kwakhala malo opweteka kwambiri pakupanga kwa OBC.

- Kusanthula kwaukadaulo kwazomwe zimayambitsa -

Choyambitsa vutoli chagona pakulephera kwazinthu ndi njira zama capacitor achikhalidwe:

Ma electrolyte wamba amasinthasintha mosavuta kutentha kwambiri, zomwe zimapangitsa kuti capacitance iwonongeke komanso kuwonjezeka kwa ESR;

Mapangidwe okhazikika amakhala ndi kachulukidwe kakang'ono ka capacitance, zomwe zimapangitsa kuti zikhale zovuta kulinganiza voteji ndi mphamvu;

Kusadalirika kosindikiza kokwanira kumabweretsa kutayikira m'malo ogwedezeka.

Zofunikira zazikulu monga capacitance density, ESR @ 100kHz, zovoteledwa pakalipano @ 105°C, ndi moyo wautali zimakhudza mwachindunji kupambana kwadongosolo.

- Mayankho a YMIN ndi Ubwino Wanjira -

Mndandanda wa YMIN LKD umagwiritsa ntchito njira zingapo zatsopano:

1. Chojambula chapamwamba cha electrode: Kuchulukitsa mphamvu pa voliyumu ya unit, kuchepetsa voliyumu ndi 20% mpaka 40% poyerekeza ndi zinthu zofanana;

2. Low-impedance electrolyte: Mogwira mtima amachepetsa ESR ndikuwongolera kulekerera kwapamwamba kwambiri;

3. Kumangirira kusindikiza ndi kuphulika kwa mawonekedwe: Kudutsa kuyesa kwa 10G kugwedezeka kwa kugwedezeka, kuchotsa zoopsa zowonongeka;

4. High-voltage redundancy design: Amapereka mphamvu yokwanira yamagetsi, yoyenera kugwiritsidwa ntchito pamapulatifomu a 800V ndi pamwamba.

Kutsimikizika kwa Data Yodalirika & Zosankha Zosankha

Monga tikuwonera, mndandanda wa LKD umaposa kwambiri zinthu wamba malinga ndi kukula, ESR, kukana kwa ripple, komanso moyo wautali.

- Mawonekedwe Ogwiritsa Ntchito ndi Mitundu Yovomerezeka - Mndandanda wa LKD ndiwoyenera: OBC PFC yolimbikitsa kusefa kotulutsa; Thandizo la DC-Link ndi buffering; ndi kusefa kwa DC-DC.

- Zitsanzo zovomerezeka -

LKD 700V 150μF 25×50: Oyenera 1200V DC-Link machitidwe;

LKD 500V 330μF 25 × 50: Oyenera kusefa mkulu-mphamvu mu kachitidwe 800V;

LKD 450V 330μF: Miyezo kukula ndi zofunika mphamvu;

LKD 500V 220μF: Yoyenera kugwiritsidwa ntchito pazinthu zopanda malo.

Mapeto

Mndandanda wa YMIN's LKD, kupyolera mu zipangizo zamakono ndi zomangamanga, zimakwaniritsa bwino kudalirika ndi zofunikira za kukula kwa ma capacitor mumagetsi apamwamba, othamanga kwambiri, komanso kutentha kwambiri. Yakhala capacitor yosankha ntchito za OBC m'makampani ambiri otsogola amagalimoto. Timathandizira zitsanzo za ntchito ndi chithandizo chaukadaulo, kuthandiza mainjiniya kukhazikitsa ma projekiti mwachangu.
