Kuthetsa Vuto la Kugwiritsa Ntchito Mphamvu Zazikulu za OBC/DCDC Units: Kuvumbulutsa Deta Yoyezedwa ya YMIN's Solid-Liquid Hybrid Capacitors

Galimoto Yatsopano Yamagetsi OBC - Zochitika Zavuto ndi Zowawa

M'makina awiri-m'modzi a OBC & DC / DC amagetsi atsopano amagetsi, kukana kwa capacitor ndi kukhazikika kwaposachedwa pambuyo pa kugulitsanso kwakhala zinthu zazikulu zomwe zimakhudza magwiridwe antchito onse komanso kutsata malamulo. Izi ndizowona makamaka pamene kutayikira kwa capacitor kumawonjezeka pambuyo pa kutenthedwa kwa kutentha kwambiri, zomwe zimapangitsa kuti mphamvu yonse ipitirire miyezo yoyendetsera.

Root Cause Technical Analysis

Kutayikira kosadziwika bwino nthawi zambiri kumachokera ku kuwonongeka kwa kupsinjika kwa kutentha panthawi ya reflow soldering, komwe kumabweretsa kuwonongeka kwa filimu ya oxide. Traditional electrolytic capacitors sachita bwino munjira iyi, pomwe ma capacitor olimba amadzimadzi osakanizidwa amathandizira kwambiri kukhazikika kwa kutentha kwambiri kudzera muzinthu zokongoletsedwa ndi kapangidwe kake.

Mayankho a YMIN ndi Ubwino wa Njira

Mndandanda wa YMIN wa VHT/VHU umagwiritsa ntchito dielectric wosakanizidwa wa polima ndi mawonekedwe: - ESR yotsika kwambiri (yotsika ngati 8mΩ); - Kutayikira panopa ≤20μA; - Imathandizira 260 ° C reflow soldering yopanda ntchito yoyendetsa; - Kuyesa kwathunthu kwa CCD capacitor ndi kuyesa kwanjira ziwiri kumatsimikizira zokolola.

Kutsimikizira Deta ndi Kufotokozera Kudalirika

Kuyesa magulu 100 a zitsanzo, VHU_35V_270μF pambuyo pa kutsekemera kwazitsulo kunasonyeza: - Avereji yotayikira panopa inali 3.88μA, ndi kuwonjezeka kwapakati pa 1.1μA pambuyo pa kutulutsanso; - Kusiyanasiyana kwa ESR kunali mkati mwazoyenera; - Kutalika kwa moyo kudapitilira maola 4000 pa 135 ° C, oyenera malo ogwedezeka pamagalimoto.

VHU_35V_270μF_10*10.5 Parameter Kuyerekeza Kusanachitike ndi Pambuyo Kubwereranso

Mawonekedwe a Ntchito & Mitundu Yovomerezeka

Amagwiritsidwa ntchito kwambiri mu:

- Zosefera za OBC / zotulutsa;

- Kuwongolera kwamagetsi kwa DCDC converter;

- High voltage platform power modules.

Mitundu yolangizidwa (yonse yokhala ndi kachulukidwe kwambiri komanso kapangidwe kakang'ono):

- VHT_35V_330μF_10×10.5

- VHT_25V_470μF_10×10.5

- VHU_35V_270μF_10×10.5

- VHU_35V_330μF_10×10.5

TSIRIZA

YMIN Capacitor imagwiritsa ntchito deta kutsimikizira kudalirika ndi ndondomeko kuti zitsimikizire kusasinthasintha, kupereka mayankho a capacitor "okhazikika komanso okhalitsa" pamapangidwe atsopano amagetsi amagetsi.
