Mmaraka oa ho tjhaja o potlakileng oa ho tjhaja o tla ho hola ka " Leha ho le joalo, ho Ikokotsisoa Ho Ikokaleha (EMI) Phephetso e 'ngoe ea maemo a 68% ea maemo a qobang ka matla a EMIS. Sengoliloeng sena se senola maano a sebetsang a ho loants'a EMI ha a ntse a boloka katleho ea ho tjhaja.
1. Mehloli ea EMI ea EMI e qosa ka potlako
1.1 switjha frequency prequency
Libapali tsa sejoale-joale tsa Gallium (Gallium nitride) li sebelisa lisosa tse fetang 1 MHZ, li hlahisa ho sokolla hardonic ho fihlela ho la 30. Thutong ea Mit e 2024 e senotse hore tse 65% tsa EMI li tsoa ho:
•Mosfet / igbt switjha (42%)
•Inductor-Core Satery (23%)
•PCB) Parasitics (18%)
1.2 E radiated vs. e entsoe emi
•EMI: Lithaba ka 200-500 MHZ Range (FCC Class - Lind Class Bik: ≤4
•E tsamaisoaEMI: U nyatsa ka 150 khz-30 Mhz Band (Cisp3 Band (Cister 32
2. Mekhoa ea Core Mitigation
2.1 Sekhahla sa meralo ea sebaka
Mokhoa o 3 oa sethala sa 3-60:
• Motsoako-Boemo ba Lebelo:Litsela tsa Ferrite ho la DC-DC Phetoho (e fokotsa lerata ka 15-20 DB)
• LITLHAKISO TSA BOPHELO:Motsamaisi oa PCB e tletseng copper-e nang le koporo (li-blocks 85% ea couppling e haufi)
• Ho kenngoa ka sekhahla sa sistimi:Mu-Metal Introsures le merusu e khabisitsoeng (attenuation: 30 db @ 1 ghz)
2.2 Topologia ea Filter ea Filter
• Lifilimi tsa mofuta o fapaneng:3d-odara LC Phetoho (80% e fanang ka maikutlo @ 100 khz)
• Chokes ea mofuta o tloaelehileng:Cores ea nancorstalling e nang le tlolo ea> 90% e ts'oaroe e le kannete ho 100 ° C
• Ho hlakoloa ke EMIHo fallisoa ka nako ea 'nete (ho fokotsa palo ea motsoako ka 40%)
3. Rala maano a sebetsang
3.1 PCB Mekhoa e metle ka ho fetisisa
• Tsela ea ho itšehla thajana.Boloka bophara ba 5 × pokello ea bophara pakeng tsa matla le mela ea matšoao
•Mabatooa a 4-likaletara tse nang le <2 mωtians (e fokotsa bounce ka 35%)
• ka stitching:0.5 mm Pranch ka li-arrays tse haufi le libaka tse phahameng tse phahameng
3.2 Thermal-emi Co-Arsey
TLHOKOMELISO E FUMANANG:
4. Ho lumellana le li-protocol tsa tlhahlobo
4.1 FramE
• ho sekaseka sebaka sa tšimo:E supa hotspots tse nang le qeto e ka bang 1 mm spatial
• Sebaka sa Domain Refetometry:Fumana missatches tsa kahare nakong ea 5% ho nepahala
• software ea EMC e ikemetseng:Ansy Hfss Sibs Bapisa le liphetho tsa lab haufi
4,2 Setifikeiti sa Setifikeiti sa Lefatše
• fcc karolo ea 15 subpart b:Mandats <48 DBμv
• CISTR 32 Sehlopha sa 3:E hloka 6 DB e tlase ho feta sehlopha sa B ka har'a libaka tsa indasteri
• Mil-Std-461g:Lits'oants'o tsa Lichelete tsa Sesole bakeng sa Litsamaiso tsa Chasi ea ho Chaena
5. Litharollo tse hlahang le lifofane tsa lipatlisiso
5.1 Meta - Lithapelo tsa Mathata
Mekhoa e thehiloeng Graphene e bontša:
•97% ea ho amohela katleho ho 2.45 ghz
•Lithane tsa limilimithara tse 0,5 ka ho itšehla thajana ho 40 db
5.2 Digital Twin Technology
Litsamaiso tsa Nako ea 'Nete ea Bothomo:
•Ho hokahana ha 92% pakeng tsa li-prototypes tsa boleng bo botle le liteko tsa 'mele
•Fokotsa meqomong ea ntlafatso ka 60%
Ho matlafatsa tharollo ea hau ea chelete ea hau ka theknoloji
Khetho ea Mov e etellang pele e le moetsi oa Mov, Re thabela ho lopolla mekhoa ea ho tjhaja e ntlafatsa maano a ho khaola a boletsoeng sehloohong sena. Matla a rona a feme ea mantlha a kenyelletsa:
• Master a Emis e felletseng:Ho tsoa mesebetsing e mengata ea meralo e mengata ho ai-chankaneng ea dijithale, re kenya tšebetsong merero e hlophisitsoeng ka li-protocol tse netefalitsoeng tsa tlhahlobo.
• Thermal-emi Co-Co-boenjiniere:Litsamaiso tsa ho futhumatsa molemong oa phetoho ea liphetoho tsa phetoho ea liphetoho tsa phetoho
• Merero e sa sebetseng hantle:94% ea bareki ba rona e fihlella FCC / CisPRiance nakong ea tlhahlobo ea pele, ho fokotsa nako ka 50%.
Hobaneng ha u sebelisa molekane?
• Litharollo tsa Qetellong:Moralo o Ratehang ho tloha ho li-chargers tse 20 tsa depo ho 350 kw ultra-indstems
• 24/7 Ts'ehetso ea Tekheniki:Emi Disconostics and findware ts'ebetso ea firthware ka pono ea hole
• Lintlafatso tsa Bopaki ba Bopaki ba Bokamoso:Grafene Meta
Ikopanye le sehlopha sa rona sa boenjineribakeng sa emi ea mahalaTlhahlobo ea lits'ebetso tsa hau tse teng kapa ho hlahloba ronali-postfolio tse netefalitsoeng pele li qotsitsoeng pele. A re boreng moloko o latelang oa ho kena-kenana le tharollo ea ho kena-kenana le mathata.
