Suuqa lagu dallaco ee Degdega ah ayaa la saadaalinayaa inuu ku koraan suuliga ee 22.1% laga soo bilaabo 2023 ilaa 2030 (Cilmi-baarista Grand. Si kastaba ha noqotee, faragelinta elektromagentic (EMI) ayaa weli ah caqabad muhiim ah, oo leh 68% oo ah fashilka nidaamka ee aaladaha korantada ee sare ee ay ka heleen maareynta EMI ee aan habooneyn (Ieee macaamil ganacsi elektiroonig ah, 2022). Qodobkaani wuxuu soo bandhigay istiraatiijiyado ficil ah oo lagula dagaallamayo EMI iyadoo la ilaalinayo hufnaanta ku-meel-gaarka ah.
1. Fahamka ilaha EMI ee si dhakhso ah u dallac
1.1 Bedelka Dhaqdhaqaaqa Soo noqnoqda
Cardijiyada cas (Gallium Nitium Nitide) waxay ku shaqeeyaan isdabajoogyada ka badan 1 MHz, oo abuuraya dhaleeceyn is-waafajin ilaa 30-aad. Daraasad 2024 oo mit ah ayaa shaaca ka qaaday in 65% ee qiiqa EMI ay ka soo jeedaan:
•Mosfet / IGBT Beddelka Kartida (42%)
•Fadhiga-qurxinta core (23%)
•PCB Boodht-ka dul-dhigista (18%)
1.2 Rasaasta vs. waxaa loo sameeyay EMI
•Rulated EMI: Peaks at 200-500 MHZ Range (FCC Class B xadidan: ≤40 dBμv / m @ 3m)
•La qabtayEMI: Halis ah 150 Khz-30 MHZ Band (CISPR 32 Starerds: ≤60 dBμv Quasi-peak)
2. Farsamooyinka yareynta aasaasiga ah
2.1 Dhismaha lakabka oo lakabka leh
Habka 3-heerku wuxuu keenayaa 40-60 dB yaraanta:
• Gawaarida heer-heersare ah:Ferrite Beeraha ku saabsan wax soo saarka shisheeyaha DC-DC (waxay yareysaa dhawaqa 15-20 dB)
• Xakamaynta heerka-hoose:Cirbadaha waardiyaha ee la buuxiyay ee PCB
• Nidaamyada heerka-nidaamka:Q-port-ka xarkaha leh ee leh gaskoonada kontoroolka ah (scement: 30 dB @ 1 ghz)
2.2 Toport toport-ka sare ee shaandhaynta
• Qalabka miirayaasha qaabka kaladuwan:3-aad-amar-qaadis LC ah (80% xakamaynta dhawaaqa @ 100 khz)
• Cheat-mode-mode-modes:Nanocrystaleine cores oo leh> 90% haynta guud ee 100 ° C
• Banaaneynta firfircoon EMI:Shaandhaynta la-qabsashada waqtiga-dhabta ah (waxay yareysaa tirada qaybta 40%)
3. Istaraatiijiyadaha naqshadeynta naqshadeynta
3.1 PCB qaabeynta waxqabadka ugu wanaagsan
• Go'doominta Wadnaha ee Halis ah:Joogtee 5 × pace balacal ballaadhan oo u dhexeeya awoodda iyo xariiqda calaamadaha
• Kordhinta diyaaradda diyaaradda dhulka:4-lakab lakab ah oo leh <2 mω Khilaafaadka (waxay yareysaa dhulka oo dhan 35%)
• Viatsing:0.5 mm garoonka dhex mara oo ku wareegsan aagaga sare / dt
3.2 Wada-dhiska kuleylka-eMI
Tusaalooyinka kuleylka ayaa muujinaya:
4. U hoggaansanaanta & tijaabinta borotokoolka
4.1 Qaab dhismeedka imtixaanka ka hor
• Sawirka gudaha-dhow:Wuxuu cadeeyaa meelaha meelaha meelaha kulul ee leh 1 mm xalka xalka
• Waqti--hoosaadku ka milkii:Waxay ku yaalliin isku-darka khaldan 5% sax ah
• Software-ka EMC ee otomatiga ah:ASSYS HFSs Monilations Prossunces waxay ka dhalataa natiijooyinka sheybaarka ee ± 3 dB
4.2 Shahaadada Caalamiga ah ee Shahaadada Caalamiyeed
• FCC Qaybta 15 Subpart B:Waajibaadka <48 dBV / m shucaaca qiiqa (30-1000 mhz)
• Cispr 32 CLASS 3:Waxay u baahan tahay 6 db qiiqa ka hooseeya qiiqa ka badan fasalka b bey'adda warshadaha
• Mil-STD-461G:Faahfaahinta milatariga ee nidaamyada lagu dallaco ee ku jira rakibaadda xasaasiga ah
5. Xalka soo baxay & safka hore ee cilmi-baarista
5.1 Meta-Maaddooyinka
Jasiiradaha ku saleysan naqshaduhu waxay muujinayaan:
•97% Waxqabadka Ka Bixinta Khasaarida 2.45 GHz
•0.5 mm dhumucun leh 40 db go'itaan
5.2 Teknolojiyada Twin Dijital ah
Nidaamyada saadaalinta waqtiga-waqtiga-waqtiga-waqtiga:
•Isku xidhka 92% ee u dhexeeya tusaalayaasha guryaha iyo tijaabooyinka jirka
•Waxay yareysaa wareegga horumarka 60%
Awood siinta xalkaada EV ee aad ku tiirsan tahay khibrad
Linkower sida hogaamiya soo-saareyaasha EV ee The Charge, waxaan ku takhasustay gaarsiinta nidaamyada degdegga ah ee EMI-ka ee si aan kala go 'lahayn u dhexgalin istaraatiijiyada-geedaha goynta ah ee lagu qeexay maqaalkan. Awooddayada aasaasiga ah ee warshadda waxaa ka mid ah:
• Cashuur buuxa emi sery:Laga soo bilaabo naqshadeeye lakab ah oo lakabka ah ee loo yaqaan 'Multi-lakabka' Twin oo Dijital ah oo Dijitaal ah oo loo kaxeeyey Twin.
• Injineerka kuleylka kuleylka ah:Nidaamyada qaboojinta-ka-qaboojinta wejiga-ka-qaboojinta wejiga-ka-dhigista
• Naqshadeynta Diyaarinta-Diyaargarowga ah:94% macaamiisheena waxay gaaraan FCC / CISPR oo u hoggaansanaanta tijaabada wareega koowaad, yareynta waqtiga-suuqa 50%.
Maxay naga wada shaqeeyaan?
• Xalka dhamaadka-dhamaadka:Naqshadeynta looxun ee laga soo bilaabo 20 KW DETTOT SCWGERS ilaa 350 KW Ultra-Degmada
• 24/7 Taageero Farsamo ah:Astaamaha baaritaanka EMI iyo codeynta firmware iyada oo loo marayo kormeerka fog
• Kordhinta casriyeynta mustaqbalka:Garaafka meta ee loo yaqaan 'spapene meta'
La xiriir kooxdayada injineerinkaloogu talagalay eMI bilaash ahHantidhawrka nidaamkaaga jira ama sahamiyoXaraashka parale ee lagu xaqiijiyey portfolios. Aynu wada-soo uruurinno jiilka soo socda ee faragelinta fariimaha, oo si hufan oo sharci ah.
