Technical Deep Dive | Kodi DC-Link Film Capacitors Angathetse Bwanji Kuthamanga kwa Voltage ndi Kudalirika Kwazovuta mu 800V Electric Drive Platforms?

Mawu Oyamba

Pamene 800V high-voltage platforms akukhala odziwika mu magalimoto atsopano amagetsi, magetsi oyendetsa magetsi akuika zofuna zapamwamba pazochitika zapamwamba za DC-Link capacitors. Ma capacitor amtundu wa aluminiyamu electrolytic capacitor, ocheperako chifukwa cha kuchuluka kwa ESR komanso kuyankha pafupipafupi, amakonda kukwera kwamagetsi, kuletsa magwiridwe antchito komanso kulepheretsa magwiridwe antchito a SiC.

Mayankho a YMIN Film Capacitor

- Kusanthula kwaukadaulo wa Root Cause - Chifukwa cha mawonekedwe awo azinthu komanso kapangidwe kake, ma aluminiyamu electrolytic capacitor amakhala ndi ESR yayikulu komanso ma frequency otsika odziwonetsa okha (nthawi zambiri amangozungulira 4kHz). Pansi pa ma switch ma frequency apamwamba, kuthekera kwawo kotengera ma frequency apamwamba kwambiri sikukwanira, kumayambitsa kusinthasintha kwamagetsi a basi, komwe kumakhudza kukhazikika kwadongosolo ndi moyo wa chipangizo chamagetsi. - Mayankho a YMIN ndi Ubwino Wanjira -YMIN's MDP mndandandamakina opanga mafilimu amagwiritsa ntchito filimu yazitsulo ya polypropylene ndi njira yatsopano yokhotakhota kuti akwaniritse zotsatirazi: ESR imachepetsedwa kufika pa milliohm, kuchepetsa kwambiri kutayika kwa kusintha; ma frequency a resonant amachulukitsidwa mpaka makumi a kHz, amagwirizana kwathunthu ndi zofunikira pakugwiritsa ntchito pafupipafupi kwa SiC/MOSFETs; ndipo ubwino wawo umaphatikizapo kupirira kwamphamvu kwambiri, kutsika kochepa kwaposachedwa, ndi moyo wautali, kuwapangitsa kukhala oyenera kwambiri pamagetsi othamanga kwambiri, othamanga kwambiri.

Mawonekedwe Ogwiritsa Ntchito Ndi Mitundu Yovomerezeka -

Mlandu Wodziwika Wogwiritsa Ntchito: Pulatifomu yayikulu yamagetsi ya 800V yamagetsi imagwiritsa ntchito ma capacitor asanu ndi atatu a MDP-800V-15μF mudera la DC-Link la inverter yayikulu yoyendetsera, ndikuchotsa bwino ma 22 450V aluminiyamu electrolytic capacitor. Izi zimachepetsa dera la PCB ndi kupitirira 50%, zimachepetsa nsonga yamagetsi ya basi ndi 40%, komanso kumapangitsa kuti ntchito ikhale yabwino kwambiri ndi pafupifupi 1.5%. - Zitsanzo zovomerezeka -

Mapeto
Mndandanda wa YMIN MDP sikuti umangogwira ntchito kwambiri komanso ndi wowongolera magetsi pamakina othamanga kwambiri, othamanga kwambiri. Itha kuthandiza mainjiniya kuthana ndi zovuta zamapangidwe ndikuwongolera bwino magwiridwe antchito ndi kudalirika kwadongosolo.
