1.2 Radiated vs. akaitirwa EMI
•Yakatsemuka EMI: Peaks pa 200500 MHz Range (FCC Class B Moderits: ≤40 DBμV / M @ 3m)
•KuitiswaEMI: Kutsoropodza muna 150 KHz-30 MHZ BAND (CIS 32 Mirayiridzo: ≤60 DBQV Quasi-Peak)
2. Miraidhi maitiro maitiro
2.1 Multi-layer ichivharidzira Architecture
Iyo 3-nhanho nzira inotungamirwa 40-60 DB Chikonzero:
• Chikamu - Chikamu Chekudzivirira:Ferrite Beads paDc-DC Converter Outputs (inoderedza ruzha ne15-20 DB)
• Board-levelmment:Copper-Yakazadzwa PCB Guard Rings (Blocks 85% yePedyo-Dead Coupling)
• system-level yakavharirwa:Mu-simbi esimbi ine maitiro ekugadzirisa magetsi (Attenuation: 30 DB @ 1 GHZ)
2.2 Yepamhepo Firita Tapologies
• dzakasiyana-maitiro mafirita:3rd-Order Lc Kugadziriswa (80% Ruzha Kudzvinyirira @ 100 KHz)
• Zvakajairika-modhi zvivakwa:Nanocrystalline cores ne> 90% yekunakidzwa kuchengetedza pa100 ° C
• Active EMI kubviswa:Chaiyo-nguva inochinjika kusefa (inoderedza chikamu kuverenga ne40%)
3. Dhizaini yekugadzirisa maratidziro
3.1 PCB yakagadzirirwa maitiro akanakisa
• Nzira Inoshorwa Kuzviparadzanisa:Chengetedza 5 × Trace upamhi hwekuparadzanisa pakati pesimba uye masaini mitsara
• Ground Plan Optimization:4-layer mabhodhi ne <2 mωxedance (inoderedza pasi bhuruu ne 35%)
• kuburikidza nekurova:0.5 mm pitch kuburikidza ne arrays kutenderera yakakwira-di / dt nzvimbo
3.2 Thermal-EMI co-dhizaini

4. Kuteerana & kuyedza protocol
4.1 Pre-Kuteedzera Kuedza Chimiro
• Pedyo-munda kuongorora:Inozivisa hotspots ne1 mm spatial resolution
• Nguva-Domain Represmeometry:Inowana zvisingakwanisi mismatches mukati me5% chaiyo
• otomatiki emc software:Ansys HFSS Simples MechiMutambo Lab Mhedzisiro Mukati ± 3 DB
4.2 Global Certification Roadmap
• FCC Chikamu 15 Subpart B:Mostals <48 DBμV / M Radiated emissions (30-1000 MHZ)
• CISP 32 Kirasi 3:Inoda 6 dB yakaderera emissions kupfuura kirasi B mune maindasitiri endustments
• mil-std-461g:Mauto-giredhi remagirini ekubhadhara masisitimu mune zvinangwa zvekuisa
5. Kupinza Solutions & Research Fronters
5.1 meta-zvinhu zvinobata
Grapenh-based Metamargials inoratidza:
•97% Kubata Kwekubudirira pa 2.45 GHZ
•0.5 mm ukobvu ne40 DB yekuzviparadzanisa
5.2 Dhijitari Twin Technology
Chaiyo-nguva Emi kufungidzira masisitimu:
•92% kuwiriraniswa pakati pevirtual prottuetpes uye bvunzo dzemuviri
•Inoderedza masendimita ekusimudzira ne60%
Kupa simba rako reE EV kubharigging mhinduro pamwe nehunyanzvi
LINEPOwer seinotungamira EV Charger Mugadziri, TINOGONESA KUTI VADZIDZE EMI-YAKANYANYA KUSVIRA MABHUKU ANOGADZIRA SEAMBULY SEPRTETION SHEMA ZVINONYANYA KUTI ZVINOGONESESWA MUZVINHU ZVINOGONESWA MUCHENJERI Mafekitori efekitari anokanganisa zvinosanganisira:
• Yakazara-Stack EMI Mastery:Kubva ku yakawanda-danda rakadzivira madhiri kuAI-Drive
• Thermal-EMI co-engineering:Proprrietary-shanduri inotonhorera systems inochengetedza <2 dB EMI kusiyana-siyana kuyambuka -40 ° C kusvika 85 ° C.5 ° C.5 ° C.5
• Certification-Gadzirira Dhizaini:94% yevatengi vedu vanowana FCC / CISP kureverera mukati mekutanga-kutenderera kwekutenderera, kuderedza nguva-kune-musika ne50%.
Nei mumwe wake pamwe nesu?
• Kupera-kusvika-kupera mhinduro:Zvigadzirwa zvinogadzirwa kubva 20 kw depot charger to 350 kw yopa-nekukurumidza masisitimu
• 24/7 technical rutsigiro:EMI Diagnostics uye Firmware Optimization kuburikidza neKutarisa Kuongorora
• Remangwana-humbowo kukwidziridzwa:Grapheye meta-zvinhu zvinodzokororazve 5G-inoenderana kubhadharisa network
