Isoko ryihuta ryisi yose riteganijwe gukura kuri Cagr ya 22.1% kuva 2023 kugeza 2030 (reba neza Ubushakashatsi, 2023), bitwarwa no kuzamuka ibinyabiziga by'amashanyarazi na electiable. Nyamara, kwivanga kw'ibisobanuro (EMI) bikomeje kuba ikibazo gikomeye, hamwe na 68% by kunanirwa kwa sisitemu mu micungire y'amashanyarazi yo hejuru yakurikiranye ku micungire ya emi (ibikorwa bya IEES kuri Electronics, 2022). Iyi ngingo yashyize ahagaragara ingamba zifatika zo kurwanya EMI mugihe ukomeje kwishyuza imikorere.
1. Gusobanukirwa emi amasoko yo kwishyuza byihuse
1.1 Guhindura imirongo
Gan igezweho (Gallium Nitride) Amashanyarazi aherekeje kuri 3 MHZ, Kubyara Guhuza Kumurongora kugeza kuri 10. Ubushakashatsi bwa mit 2024 bwerekanye ko 65% by'umwuka wa EMI baturuka kuri:

•Indumu-yibanze (23%)
•PCB imiterere ya parasitike (18%)
1.2 imirasire ya emi
•Imirasire EMI: impinga muri 200-500 mhz intera (icyiciro cya FCC CLUT: ≤40 DBV / M @ 3m)
•ByakozweEMI: Kera cyane muri 150 KHZ-30 MHZ Itsinda (Cispr 32: ≤60 DBV Quasi-peak)
2. Tekinoroji ya tuntuation
2.1 Ubwubatsi Bwububiko Bukuru
Uburyo 3-Stage Yerekana 40-60 DB Gutesha agaciro:
• Ingabo-zigize urwego:Amasaro ya Ferrite kuri DC-DC Guhindura Ibisubizo (bigabanya urusaku kuri 15-20 db)
• Ibikubiyemo byo murwego:Umuringa wuzuye PCB izarinda impeta (guhagarika 85% bya hafi-umurima coupling)
• Sisitemu-Urwego Uruzitiro:Mu-Metal Avercosures hamwe na gaskets igenda
2.2 Akayunguruzo ka Topologies
• uburyo butandukanye-buryo:Icya 3-gahunda LC iboneza (80% urusaku # 100 Khz)
• Gukora ibintu bisanzwe-uburyo:Nanocrystalline Cores hamwe na> 90% yo kugumana ubutumire kuri 100 ° C.
• Gusebya EMI iseswa:Kuyungurura-igihe cyo kuyungurura (bigabanya ibice bibara 40%)
3. Igishushanyo mbonera cyo guhitamo ingamba
3.1 PCB imiterere yimikorere myiza
• Inzira ikomeye Kwigunga:Kubungabunga 5 × ubugari bwa trace hejuru yububasha nibyapa
• Indege yo hasi yerekana:Imbaho 4-Igice hamwe <2 Mω Impetance (Kugabanya Bounce ya 35%)
• binyuze mu kudoda:0.5 mm pitch ukoresheje inkuta hirya no hino-di / dt zone
3.2 Thermal-emi
Ubushyuhe bwo kwerekana:
4. Kubahiriza & Gupima Porotokole
4.1 Urwego rwo kwipimisha mbere
• Hafi ya-Scanning:Kumenya amazu akomeye hamwe na mm 1 mm
• Igihe-domaine iragaragaza:Guhuza Impetance Mismatches muri 5%
• Automatily Expey:Anys endutions pules bihuye nibisubizo bya laboramire kuri ± 3 db
4.2 Icyemezo cyisi yose
• Igice cya FCC 15 Subpart B:Manda <48 dbV / m imyuka ihumanya (30-1000 MHz)
• Cispr 32 Icyiciro cya 3:Bisaba imbyutse 6 db hasi kurenza ishuri b mubidukikije
• Mil-STD-461G:Ibice byicyiciro cya gisirikare cyo Kwishyuza Sisitemu yo kwishyiriraho
5. Ibisubizo bivutse & Imipaka yubushakashatsi
5.1 Meta-Ibikoresho Bikurura
Metathene-ashingiye kuri Metatherials yerekana:
•97% Kwinjira neza kuri 2.45 GHZ
•0.5 mm ubunini hamwe na 40 db kwigunga
5.2 IGITONDO
Sisitemu-Igihe cya EMI Imyandikire:
•92% bifitanye isano hagati ya prototypes yimikorere nibizamini byumubiri
•Kugabanya inzinguzingo yiterambere na 60%
Guha imbaraga ibisubizo byawe byo kwishyuza hamwe nubuhanga
Guhuza nkibisobanuro bya Ev charger, tuboneka mugutanga sisitemu yihuta yo kwishyuza inanga ihuza ingamba zo gukata inyuguti zivuzwe muri iyi ngingo. Imbaraga zuruganda rwibanze zirimo:
• SHAKA CYIZA EMI MASTY:Kuva kubwubatsi bwikibuga kinini cyikigo cya Digital Digital Dicicals, dushyira mubikorwa ibishushanyo bya mil-461G-461G-461G-yujuje ibyango byemejwe na protocole yemejwe.
• Ubushyuhe-EMI bufatanye:Imyifatire ya Proshit yicyiciro cya Prooning ikomeza <2 db emi gutandukana hakurya ya -40 ° C kugeza 85 ° C ikora.
• Imyiteguro-yiteguye94% by'abakiriya bacu bagera kuri FCC / Cispr kubahiriza mubyiciro byambere, bigabanya igihe-ku isoko kugeza 50%.
Kuki dukorana natwe?
• Ibisubizo byanyuma-byimperuka:Ibishushanyo mboherereje kuva kuri 20 KW depot kugeza kuri 40 ya KW ultra-byihuse
• Inkunga ya tekiniki:Emi diagnostics hamwe no guhitamo software ukoresheje gukurikirana kure
• kuzamura ibimenyetso bizaza:Grayphene Meta-Ibikoresho Retrofits kuri 5G-ihuza imiyoboro yo kwishyuza
Menyesha Ikipe Yubwubatsikuri emiubugenzuzi bwa sisitemu yawe iriho cyangwa ishakisha ibyacuMbere yo kwishyuza Module Portfolios. Reka dufatanye ibisekuruza bizaza byo kwivanga-kubuntu, ibisubizo-byimazeyo.
