Lub ntiaj teb ceev them kev lag luam yog npaj kom loj hlob ntawm ib qho kev tshawb fawb ntawm ib qho kev tshawb fawb txog hluav taws xob thiab cov hluav taws xob Portable. Txawm li cas los xij, kev cuam tshuam hluav taws xob hauv hluav taws xob (EMI) tseem ceeb heev, nrog 68% ntawm cov cuab yeej them nqi zog hauv kev tswj hwm Cov kab ntawv no nthuav tawm cov tswv yim ua haujlwm los tawm tsam EMI thaum tuav kev them nyiaj ua haujlwm.
1. Nkag siab txog EMI qhov chaw hauv kev them nyiaj ceev
1.1 Hloov cov zog zaus
Niaj hnub Gan (Gallium Nitride) cov kev them nyiaj ua haujlwm ntawm zaus ntau dua 1 MHz, tsim cov harmonic distortions txog 30 xaj. Ib qho kev kawm tau 2024 tau qhia tias 65% ntawm EMI emissions pib los ntawm:

•Inductor-core solentation (23%)
•Pcb Layout Parasitics (18%)
1.2 radiated vs. ua emi
•Radiated emi: peaks ntawm 200-500 MHz ntau (FCC chav kawm B txwv txwv: ≤μ0 DBμV / M @ 3M)
•UaEMI: Tseem Ceeb Hauv 150 KHz-30 MHz Band (CISPL 32 Cov Qauv: ≤> Qib QUB (C≤50
2. Cov txuj ci tseem ceeb
2.1 Ntau Txheej Txheem Tiv Thaiv Architecture
Ib txoj hauv kev 3-theem tau muab rau 40-60 DB Athenuation:
• Daim thaiv tiv thaiv qib-theem:Ferrite hlaws dai ntawm DC-DC converter tawm ua tawm (txo suab nrov los ntawm 15-20 dB)
• Phau ntawv muaj-phau ntawv muaj:Tooj liab puv puv PCB zov cov neeg (thaiv 85% ntawm ze-teb coupling)
• Cov txheej txheem-qib ntim:Mu-hlau cov ntaub thaiv nrog cream gaskets (attenuation: 30 db @ 1 GHz)
2.2 Advanced Lim Topologies
• Cov khoom lim sib txawv-hom lim:Thib 3-xaj LC kev teeb tsa (80% suab nrov @ 100 KHz)
• Hom-hom daig:Nanocrystalline cores nrog> 90% porteability khaws cia ntawm 100 ° C
• Ua kom muaj kev tshem tawm EMI:Real-lub sijhawm yoog kev lim (txo cov lej suav los ntawm 40%)
3. Tsim cov tswv yim kom ua kom zoo
3.1 PCB teeb meem zoo tshaj kev coj ua
• Kev Cais Ntsiab Lus Tseem Ceeb:Tswj 5 × lw dav dav dav ntawm lub zog thiab cov paib
• Av pob zeb txhim kho kom zoo dua:4-txheej txheej nrog <2 mω impedance (txo av bounce los ntawm 35%)
• Ntawm stitching:0.5 Mm lub suab nyob ntawm cov npe nyob ib ncig ntawm cov chaw siab / DT / DT
3.2 thermal-emi co-qauv tsim
Thermal simulager:
4. Ua raws li & kuaj cov qauv
4.1 Ua ntej-ua raws li kev soj ntsuam lub moj khaum
• Kaw nyob ze-teb scanning:Qhia txog hotspots nrog 1 hli spatial daws teeb meem
• Lub sijhawm-sau txog kev xav txog:Nrhiav kev cuam tshuam tsis pub dhau 5% qhov tseeb
• Caw Kaw EMC Software:Cov tswv yim HFSS kev sim sim ua ke nrog ib lab ua haujlwm hauv ± 3 DB
4.2 Kev muaj ntawv pov thawj thoob ntiaj teb
• FCC ntu 15 subpart B:Yuam <48 dbμv / m radiated emissions (30-1000 MHz)
• CAMP 32 Hoob no 3:Yuav tsum tau 6 dB qis emissions dua chav kawm b hauv kev lag luam ib puag ncig
• MIL-STD-461g:Cov tub rog-qib specs rau them cov tshuab hauv kev sib dhos
5. Tawm cov kev daws teeb meem & kev tshawb fawb Frontiers
5.1 Meta-khoom nqus nqus
Graphene-raws li kev ua yeeb yam qhia:
•97% kev nqus kev ua tau zoo ntawm 2.45 GHz
•0.5 mm thickness nrog 40 dB kev rho tawm
5.2 digital ntxig thev naus laus zis
Tiag tiag-lub sij hawm EMI Prediction Systems:
•92% sib txheeb ntawm virtual prototypes thiab kev sim lub cev
•Txo kev txhim kho kev txhim kho los ntawm 60%
Txhawb nqa koj cov kev them nyiaj ev kev nrog cov kev txawj ntse
Linkpower ua tus thawj coj ua rau kev xa cov chaw tsim khoom EMI-optimized nrawm them cov tswv yim sib sau ua ke hauv tsab xov xwm no. Peb lub Hoobkas cov peev xwm suav nrog:
• Puv-pawg EMI Mastery:Los ntawm cov txheej txheem tiv thaiv ntau txheej rau ai-tsav digital ntxiag tas sim neej, peb siv Mil-Std-461G-ua raws cov qauv tsim tau los ntawm cov qauv muaj ntawv pov thawj.
