Biteganijwe ko isoko ryishyurwa ryihuse kwisi yose iziyongera kuri CAGR ya 22.1% kuva 2023 kugeza 2030 (Grand View Research, 2023), bitewe nubwiyongere bukabije bwibinyabiziga byamashanyarazi hamwe na elegitoroniki ishobora gutwara. Nyamara, kwivanga kwa electromagnetique (EMI) bikomeje kuba ingorabahizi, hamwe na 68% byananiranye muri sisitemu mubikoresho bikoresha amashanyarazi menshi bikurikiranwa nubuyobozi budakwiye bwa EMI (IEEE Transaction on Power Electronics, 2022). Iyi ngingo iragaragaza ingamba zifatika zo kurwanya EMI mugihe ikomeza gukora neza.
1. Gusobanukirwa Inkomoko ya EMI muburyo bwihuse
1.1 Guhindura imbaraga za Frequency Dynamics
Amashanyarazi ya GaN ya kijyambere (Gallium Nitride) akorera kumurongo urenga 1 MHz, bikabyara kugoreka kugeza kuri 30. Ubushakashatsi bwakozwe na MIT 2024 bwerekanye ko 65% byangiza imyuka ya EMI bituruka kuri:
•MOSFET / IGBT ihinduranya (42%)
•Inductor-yibanze (23%)
•Imiterere ya PCB parasitike (18%)
1.2 Imirasire irwanya EMI
•Imirasire ya EMI: Impinga kuri 200-500 MHz (Imipaka yo mu cyiciro cya FCC: ≤40 dBμV / m @ 3m)
•YayoboweEMI: Birakomeye muri 150 kHz-30 MHz band (CISPR 32 ibipimo: ≤60 dBμV quasi-peak)
2. Ubuhanga bwibanze
2.1 Ubwubatsi Bwinshi Bwubaka
Inzira y'ibyiciro 3 itanga 40-60 dB kwiyerekana:
• Kurinda urwego rwibigize:Isaro rya Ferrite kumasoko ya DC-DC ihindura (igabanya urusaku kuri 15-20 dB)
• Inzego z'ubuyobozi:Umuringa wuzuye PCB urinda impeta (uhagarika 85% yo guhuza umurima)
• Urwego rwa sisitemu:Mu-cyuma gifunze hamwe na gasketi ziyobora (attenuation: 30 dB @ 1 GHz)
2.2
• Itandukaniro-ryuburyo butandukanye:Icyiciro cya 3 LC iboneza (80% guhagarika urusaku @ 100 kHz)
• Inzoga zisanzwe:Nanocrystalline cores hamwe na> 90% kugumana permeability kuri 100 ° C.
• Iseswa rya EMI rifatika:Akayunguruzo keza-keza (kugabanya kubara ibice 40%)
3. Gutegura Ingamba zo Gukwirakwiza
3.1 Imiterere ya PCB Imyitozo myiza
• Inzira ikomeye yo kwigunga:Komeza 5 × gutandukanya ubugari hagati yimbaraga nimirongo yerekana ibimenyetso
• Kunoza indege hasi:Ibibaho 4-byuzuye hamwe na <2 mΩ impedance (igabanya ubutaka bwa 35%)
• Binyuze mu kudoda:0.5 mm ikibanza kinyuze mumirongo ikikije zone-di / dt
3.2 Ubushyuhe-EMI-Igishushanyo mbonera
Amashusho yubushyuhe yerekana:
4. Kwubahiriza & Kugerageza Porotokole
4.1 Urwego rwo Kwipimisha Mbere
• Gusikana hafi yumurima:Kumenya ahantu hashyushye hamwe na mm 1 yumwanya
• Igihe cyagenwe cyerekana:Kubona impedance idahuye muri 5% byukuri
• Porogaramu ya EMC yikora:ANSYS HFSS bigereranya ibisubizo bya laboratoire muri ± 3 dB
4.2 Igishushanyo mbonera cy'isi yose
• FCC Igice cya 15 Igice B:Manda <48 dBμV / m irasa imyuka (30-1000 MHz)
• CISPR 32 Icyiciro cya 3:Irasaba ibyuka 6 dB biri munsi yicyiciro B mubidukikije
• MIL-STD-461G:Urwego rwa gisirikari rwerekana sisitemu yo kwishyuza muburyo bworoshye
5. Ibisubizo Byadutse & Ubushakashatsi Imipaka
5.1 Meta-material Absorbers
Graphene ishingiye kubintu byerekana:
•97% yo kwinjiza neza kuri 2.45 GHz
•0,5 mm z'ubugari hamwe na 40 dB kwigunga
5.2 Ikoranabuhanga rya Twin Digital
Sisitemu nyayo yo guhanura EMI:
•92% isano hagati ya prototypes yibizamini n'ibizamini bifatika
•Kugabanya inzinguzingo ziterambere 60%
Guha imbaraga Ibisubizo byawe bya EV hamwe nubuhanga
Linkpower nkumushinga wambere wa charger ya EV, turazobereye mugutanga EMI-yihuse ya sisitemu yo kwishyuza byihuse ihuza ingamba zambere zivugwa muriyi ngingo. Uruganda rwibanze rwibanze rurimo:
• Ubuhanga bwa EMI bwuzuye:Kuva mubice byinshi bikingira imyubakire kugeza kuri AI ikoreshwa na digitale yimpanga, dushyira mubikorwa MIL-STD-461G yubahiriza ibishushanyo byemewe binyuze muri ANSYS yemewe na protocole.
• Ubushyuhe bwa EMI-EMI:Sisitemu yo guhindura-gukonjesha sisitemu ikomeza <2 dB EMI ihindagurika kuri -40 ° C kugeza 85 ° C ikora.
• Impamyabumenyi Yiteguye:94% by'abakiriya bacu bagera kuri FCC / CISPR kubahiriza ibizamini byo mu cyiciro cya mbere, bikagabanya igihe-ku isoko 50%.
Kuki Umufatanyabikorwa natwe?
• Ibisubizo birangira-birangiye:Igishushanyo gishobora kuva kuri 20 kilo ya depot ya charger kugeza kuri 350 kW sisitemu yihuta
• 24/7 Inkunga ya tekiniki:Gusuzuma EMI hamwe no gukoresha porogaramu ikoresheje kurebera kure
• Kuzamura ejo hazaza:Graphene meta-material retrofits ya 5G ihuza imiyoboro yo kwishyuza
Menyesha itsinda ryacu ryubwubatsikuri EMI kubuntukugenzura sisitemu zihari cyangwa gushakisha ibyacubyabanje kwemezwa kwishyuza module portfolios. Reka dufatanye kurema igisekuru kizaza cyo kwivanga-kubusa, gukemura ibibazo byinshi.
