Imakethi yokutshaja ngokukhawuleza yehlabathi iqikelelwe ukuba ikhule kwi-22.1% ukusuka kwi-2023 ukuya kwi-2033 ukuya kwi-2030 (i-2023), iqhutywa yimfuno yemoto kunye ne-enformics ephathwayo. Nangona kunjalo, ukuphazamiseka kwe-elektromagnetic (i-EMI) kuhlala kungumceli mngeni obaluleke kakhulu, nge-68% yokusilela kwenkqubo ephezulu yokuhlawula amandla e-AMI ekubanjweni i-E-ACTERRERT yoLawulo lwe-EME (2022). Eli nqaku lisiphileza izicwangciso ezinokwenzeka zokulwa ukulwa i-EMI ngelixa ugcina ukubiza ukusebenza.
I-1. Ukuqonda imithombo ye-EMI ngokushanga okukhawulezayo
1.1 Ukutshintsha i-frequency dynamics
I-Gan Gan (i-geliyonium witride) isebenza kwi-frequeents ngaphezulu kwe-1 MHZ, ivelisa i-gwenxa ye-hartoortic ukuya kuthi ga kwi-30 ye-odolo ukuya kuthi ga kwi-30. Isifundo se-2024
•I-Moskiet / i-Igbt yokutshintsha (42%)
•I-Insuctor-core satte (23%)

• Inqanaba leBhodi:I-PCBR ye-PCB igcwalise i-PCB i-rings (iibhloko ezingama-85% ze-coupling yendawo ekufutshane)
• Inqanaba lokuvalwa kwenkqubo:I-MU-i-Mu-intsimbi ebiyelwe nge-gasket esebenzayo (i-Attinatus: 30 DB @ 1 GHZ)
2.2 I-filter ye-filter ye-filter
• Iifilitha ezahlukeneyo zemodeli:I-3RD-ORDOLTIONS LC (80% yokunikezelwa kwengxolo @ 100 khz)
• Imo yendlela eqhelekileyo:I-Nanocrystalline Cores kunye> I-90% yokugcina ubugqi kwi-100 ° C
• Ukurhoxiswa okusebenzayo kwe-EMI:Ukucoca okwenyani
I-3. Iindlela zokulondolozwa kwendlela yokuyila
3.1 Ubume be-PCB
• I-teex yedwaGcina i-5 × traces kububanzi phakathi kwamandla kunye nemigca yomqondiso
• Uncedo lwenqwelomoya yenqwelomoya:Iibhodi ezi-4 ezinamachaphaza ane <2 mω icinezele (inciphise umhlaba nge-35%)
• nge-titch yokuThunyelwa:I-0.5 mm pitch nge-cutys ejikeleze imimandla ephezulu ye-di / dt
3.2 uyilo lwe-thermal-hini
Umzobo we-thermal ubonakalisa:
4. Iiprotokholi zovavanyo kunye novavanyo
4.1 Inkqubo-sikhokelo yovavanyo lokuthotyelwa kwangaphambili
• UkuPhononongwa kweMhlaba kufutshane:Chonga i-hotspots ngesisombululo se-1 mm sendawo
• I-Refloine ye-DemainCommentry:Latites i-mismatches ye-mismatch ngaphakathi kwe-5% yokuchaneka
• Isoftware ye-EMC ye-EMC:I-Assings HFSS ye-HFSS ihambelana nelebhu ye-LOB ngaphakathi ± 3 DB
4.2 Isiqinisekiso seNdlela yeLizwe
I-FCC yenxalenye ye-15 subpart B:Amagunya <48 DBμv / m ikhrisi (i-30-1000 mhz)
I-CISRPR 32 iklasi 3:Ifuna ukukhutshwa kwe-6 db kancinci kunodidi B kwiindawo zemveliso
• Mil-STD-461G:Iingxelo zomkhosi zomkhosi ngeenkqubo zokubiza ngokufakelwa kweenkcukacha
I-5. Izisombululo ezikhulayo kunye nePhepha zoPhando
5.1 I-Absthers ye-Meta
I-Mediamamaters esekwe eGraphene
•I-97% yokusebenza nge-2.45 GHZ
•Ubungakanani obuyi-0.5 mm nge-40 db yedwa
5.2 Itekhnoloji yamawele yedijithali
