Imakethe yokushaja esheshayo yomhlaba wonke kulindeleke ukuthi ikhule nge-cagr ka-22.1% kusuka ngo-2023 kuya ku-2023 (ucwaningo lokubuka okuhle, 2023), oluqhutshwa yisidingo esikhulayo sezimoto zikagesi kanye ne-elekthronikhi ephathekayo. Kodwa-ke, ukuphazanyiswa kwe-elekthronikhi (i-EMI) kuhlala kuyinselelo ebucayi, enamaphesenti angama-68 ekwehluleka kohlelo kumadivayisi wokushaja amakhulu alandelwa ekuphathweni okungafanele kwe-EMI (ieee ahanjiswa kumandla we-Power Electronics, 2022). Le ndatshana yembula amasu asebenzayo okulwa ne-EMI ngenkathi egcina ukusebenza kahle.
1. Ukuqonda imithombo ye-EMI ngokushaja okusheshayo
1.1 Ukushintsha amandla ama-frequency dynamics
Amashaja wesimanje we-Gan (Gallium Nitride) asebenza emafrikhwensi adlula i-1 MHz, akhiqiza ukuhlanekezela nge-harmoni kufika ku-Orderth. Ucwaningo lwe-mit olungu-2024 luveze ukuthi ama-65% ama-EMI ukuphuma emthethweni evela ku:
•I-Mosfet / Igbt Shintsha i-CHANDS (42%)
•I-Inductor-Core Saturvation (23%)
•I-PCB Layout Parasitics (18%)
I-1.2 radiated vs yenziwe e-EMI
•I-Radioted EMI: Iziqongo ku-200-500 MHZ Range (FCC Class B Imingcele: ≤40 DBμV / M @ 3M)
•KwenziweI-EMI: Egxeka ku-150 KHZ-30 MHZ Band (CISPPR 32 Izindinganiso: ≤60 DBμV Quasi-Peak)
2. Amasu wokunciphisa
2.1 Ukwakhiwa okuvinjelwe okuningi
Indlela yesigaba esingu-3 ihambisa i-attenuation engu-40-60 DB:
• Ukuvikelwa Kwezinga Lengxenye:Ubuhlalu beFerrite ku-DC-DC Converter Output (kunciphisa umsindo ngo-15-20 DB)
• Isithonjana sezinga lebhodi:Izindandatho zokuqapha zeCopper-zigcwele (amabhlokhi ama-85% wokuhlanganisa indle)
• Ukuvalelwa Kwezinga System:I-Mu-Metal Exboses enama-gaskets asebenzayo (attenuation: 30 db @ 1 ghz)
2.2 Izihlungi ezithuthukile zokuhlunga
• Ukuhlunga okuhlukile kwemodi:Ukulungiswa kwe-LC-Order-Order (80% Umsindo Suppression @ 100 KHz)
• Ama-common-mode choke:Ama-nanocrystalline cores ane-90% ukugcinwa kokugcinwa kwe-100 ° C
• Ukukhanselwa kwe-EMI okusebenzayo:Ukuhlunga okuguqukayo kwesikhathi sangempela (kunciphisa ukubalwa kwengxenye nge-40%)
3. Design actimization amasu
I-3.1 pcb ukwakheka okuhle kakhulu
• Ukuhlukaniswa kwendlela ebucayi:Gcina ukuhlukaniswa kwe-5 × trace oping phakathi kwamandla nemigqa yesiginali
• Ukusebenziseka kahle kwendiza:Amabhodi ama-4-ungqimba ane-<2 m mω yokuvadance (kunciphisa i-rounce yomhlaba ngo-35%)
• Nge-stitching:I-0.5 mm Pitch nge-array azungeze izindawo eziphakeme ze-DI / DT
3.2 Thermal-Emi Co-Design
Ukulinganisa okushisayo Khombisa:
4. Ukuhambisana nokuhlola amaphrothokholi
4.1 Uhlaka lokuhlolwa kwangaphambili
• Ukuskena kwensimu eduzane:Khomba ama-hotspots ngesixazululo se-1 mm Spatial
• Isikhathi-Domain Explowmetry:Ithola ama-Implance Mismaches ngaphakathi kokunemba okungu-5%
• Isoftware ezenzakalelayo ye-EMC:I-Ansys Hfss Ukulingisa I-Lab imiphumela yeLab ngaphakathi ± 3 dB
I-4.2 Certification Certification RoadMap
• I-FCC Ingxenye 15 I-Subpart B:Amagunya <48 dbμv / m ukukhishwa okukhishwe (30-1000 MHz)
• I-Cispr 32 Class 3:Dinga ama-6 db aphansi ukuphuma kunamakilasi B ezindaweni zezimboni
• IMil-Std-461G:Ama-specs wezempi-ebangeni lezinhlelo zokushaja ekufakweni okubucayi
I-5
5.1 Ama-Meta-Materience Aiterience
IMetaMaants esekelwe e-graphenagele:
•Ukusebenza kahle kwe-97% ku-2.45 GHz
•I-0.5 mm ubukhulu nge-40 DB Ukuhlukaniswa
5.2 Ubuchwepheshe be-Digital Twin
Amasistimu Wokubikezela Kwesikhathi Sangempela:
•I-92% Ukuxhumeka phakathi kwama-prototypes abonakalayo kanye nokuhlolwa ngokomzimba
•Kunciphisa imijikelezo yentuthuko ngo-60%
Ukunika amandla izisombululo zakho zokushaja nge-EV ngobuchwepheshe
I-LinkPrower njengomenzi weshaja we-EV, esebenza ngokukhethekile ekuletheni izinhlelo zokushaja ezisheshayo ze-EMI ezithuthukiswe ngaphandle komthungo zihlanganisa amasu wokusika onqenqemeni oluveziwe kule ndatshana. Amandla ethu efektri yethu afaka:
• Isitaki esigcwele se-EMI Mastery:Ukusuka ekwakheni ama-multi-ungqimba wezakhiwo ku-I-Digital Twin Twin Radin, sisebenzisa imiklamo yokuhambisana ne-MIL-STD-461G iqinisekiswe ngamaphrothokholi wokuhlola aqinisekisiwe we-Ansys.
• I-Thermal-EMI Co-Engineering:Amasistimu wokupholisa wesigaba-shintsha ukuguquguquka okupholile okuguqukayo <2 DB EMI e-EMI kuwo wonke amabanga angu-85 ° C.
• Imiklamo elungele isitifiketi:Ama-94% amaklayenti ethu afinyelela ukuhambisana kwe-FCC / CISPR Ngokulandela ukuhlolwa kokuqala, ukunciphisa isikhathi-kuya-imakethe ngo-50%.
Kungani ngasebenzelana nathi?
• Izisombululo zokugcina:Idizayini eyenziwe ngokwezifiso evela kuma-20 kw depot amashaja afinyelela kumasistimu angama-350 kW we-Ultra-Fast
• Ukusekelwa kwezobuchwepheshe okungu-24/7:Ukuxilongwa kwe-EMI kanye nokwenza kahle kwe-firmware ngokuqapha okukude
• Ukuvuselelwa kwekusasa:I-Graphene Meta-Material Retrofits yamanethiwekhi we-5G ahambisanayo
Xhumana neqembu lethu lobunjiniyelange-EMI yamahhalaUkucwaningwa kwamahlelo akho noma ukuhlola kwethuIphothifoliyo eqinisekisiwe eqinisekisiwe yemodyuli. Ase sidale isizukulwane esilandelayo sokuphazanyiswa kwezixazululo ezingenakuphazamisa, ngempumelelo.
