Nhanganyaya

Low-altitude flying car electronic control systems kazhinji kacho inokundikana nekuda kwepamusoro-frequency vibration panguva yekubhururuka, zvichikonzera kusagadzikana kwekutonga system mhinduro, kuderera kwekuita kusefa, uye kunyangwe tsaona dzekubhururuka. Traditional capacitors haana kukwana vibration kuramba (5-10g), zvichiita kuti vatadze kusangana nekuvimbika zvinodiwa munzvimbo dzakanyanyisa.

YMIN's Solution

Nekuwanda kwemidziyo yeSiC uye kuwedzera kwekuchinja ma frequency, ma capacitor muOBC modules anofanirwa kumirisana nepamusoro ripple currents uye thermal stress. Ordinary aluminum electrolytic capacitors anowanzo wedzera kupisa uye ane hupenyu hupfupi. Kuwana yakakwira capacitance, yakakwirira inomira voltage, yakaderera ESR, uye hupenyu hurefu mune compact package yave yepakati pain point muOBC dhizaini.

- Root Cause Technical Analysis -

Munharaunda inodedera, chimiro chemukati che capacitor chinowanzoita kuneta kwemagetsi, zvichiita kuti electrolyte leakage, solder joint cracking, capacitance drift, uye kuwedzera ESR. Nyaya idzi dzinowedzera kuwedzera simba rekupa ruzha uye voltage ripple, zvichikanganisa kushanda kwakakodzera kwezvinhu zvakakosha seMCU nemasensor.

- YMIN Solutions uye Maitiro Mabhenefiti -

YMIN's liquid-type, anti-vibration baseplate chip aluminium electrolytic capacitors inowedzera kuvimbika kuburikidza neanotevera magadzirirwo:

Yakasimbiswa anti-vibration chimiro: Nheyo yakasimbiswa uye yakagadziridzwa zvinhu zvemukati zvinopa kuvhunduka kwe10-30g;

Liquid electrolyte system: Inopa zvakanyanya kugadzikana kushanda kwemagetsi uye kupisa kupisa;

Yakakwira ripple kuramba uye yakaderera leakage ikozvino: Inokodzera yakakwirira-frequency switching magetsi ekupa mamiriro, kuvandudza sisitimu inoshanda.

Kuvimbika Data Verification & Sarudzo Mazano

Miedzo inoratidza kuti mushure memaawa 500 ekushanda munzvimbo ye30g vibration, capacitor's capacitance change rate iri pasi pe5%, uye ESR yayo inoramba yakagadzikana. Kunonoka kupindura kweSystem panguva yekuyedza vibration kwakaderedzwa zvakanyanya, uye kurongeka kwekudzora ndege kunovandudzwa, kunyanya mumamiriro ekunze asina kunaka.

Kushanda Tembiricha: -55 ° C kusvika +125 ° C (Capacitance degradation isingasviki -10% pa -40 ° C, kuve nechokwadi chekuchengetedza simba rakagadzikana uye kusefa kushanda).

Hupenyu: 2000 maawa

Vibration Resistance: 30G

Impedance: ≤0.25Ω @100kHz

Ripple Yazvino: Kusvikira ku400mA @100kHz pasi pe125°C high-temperature test condition

- Mamiriro ekushandisa uye akakurudzirwa maModheru -

Inoshandiswa zvakanyanya muyakadzika-yakadzika inobhururuka mota yemagetsi kutonga, OBC capacitor mhinduro, uye mu-motokari simba manejimendi.

Yakakurudzirwa Model:VKL(T) 50V, 220μF, 10*10-20%-+20%, Coated Aluminium Housing, 2K, Vibration-Resistant Seat Plate, CG

Iyi modhi yakashandiswa mumashandisirwo epasirese.

Mhedziso

YMIN Capacitors, iine hunyanzvi hwayo hwakasimba hwehunyanzvi uye yakaomesesa data verification, inopa kuvimbika kwakanyanya kune yepamusoro-yekupedzisira mota dzemagetsi masisitimu. Kune matambudziko ekushandisa capacitor, bata YMIN-isu takagadzirira kushanda nemainjiniya edu kukunda nharaunda dzakanyanyisa.
