• Binciken filin kusa:Yana gano wurare masu zafi tare da ƙudurin sararin samaniya 1 mm
• Nunin nazarin lokaci-yanki:Yana gano rashin daidaituwar impedance tsakanin daidaiton kashi 5%.
• Software na EMC mai sarrafa kansa:ANSYS HFSS simulations sun dace da sakamakon lab a cikin ± 3 dB
4.2 Taswirar Taswirar Taswirar Duniya
FCC Sashi na 15 Karamin Sashe na B:Abubuwan da ake buƙata <48 dBμV/m fitar da hayaki (30-1000 MHz)
CISPR 32 Class 3:Yana buƙatar ƙananan hayaƙi 6 dB fiye da Class B a cikin mahallin masana'antu
• MIL-STD-461G:Takaddun ƙayyadaddun matakan soja don tsarin caji a cikin kayan aiki masu mahimmanci
5. Maganganun Farko & Ƙungiyoyin Bincike
5.1 Meta-material Absorbers
Abubuwan metamaterial na tushen Graphene suna nuna:
•97% ingancin sha a 2.45 GHz
•0.5 mm kauri tare da keɓewar 40 dB
5.2 Digital Twin Technology
Tsarukan tsinkayar EMI na ainihi:
•Daidaita kashi 92% tsakanin samfuran kama-da-wane da gwaje-gwajen jiki
•Yana rage hawan ci gaba da kashi 60%
Ƙarfafa Maganin Cajin EV ɗinku tare da Kwarewa
Linkpower a matsayin babban mai kera caja na EV, mun ƙware wajen isar da ingantattun tsarin caji mai sauri wanda ke haɗa dabarun yankan da aka zayyana a cikin wannan labarin. Babban ƙarfin masana'anta sun haɗa da:
• Jagorar EMI Cikakkun Tari:Daga gine-ginen garkuwa da yawa zuwa na'urorin tagwaye na dijital da AI-kore, muna aiwatar da ƙira masu yarda da MIL-STD-461G waɗanda aka inganta ta hanyar ka'idojin gwaji na ANSYS.
• Injiniyan Haɗin gwiwar Thermal-EMI:Tsarukan sanyaya canjin lokaci na mallakar mallaka suna kiyaye <2 dB EMI bambancin tsakanin -40°C zuwa 85°C jeri na aiki.
• Shirye-shiryen Takaddun Shaida:Kashi 94% na abokan cinikinmu sun cimma yarda da FCC/CISPR a cikin gwajin zagaye na farko, rage lokaci zuwa kasuwa da kashi 50%.
