Ntlha ea bohlokoa ea PCIM
Shanghai, Loetse 25, 2025—Ka 11:40 AM kajeno, Foramong ea Theknoloji ea PCIM Asia 2025 Holong ea N4 ea Setsi sa Lipontšo sa Machaba se Secha sa Shanghai, Monghali Zhang Qingtao, Motlatsi oa Mopresidente oa Shanghai YMIN Electronics Co., Ltd., o fane ka puo ea sehlooho e nang le sehlooho se reng “Litšebeliso tse Ncha tsa Li-Capacitors Litharollong tse Ncha tsa Semiconductor tsa Moloko oa Boraro.”
Puo e ne e shebane le diphephetso tse ntjha tse hlahisitsweng ke ditheknoloji tsa semiconductor tsa moloko wa boraro tse kang silicon carbide (SiC) le gallium nitride (GaN) bakeng sa di-capacitor tlasa maemo a feteletseng a tshebetso a kang maqhubu a phahameng, motlakase o phahameng, le mocheso o phahameng. Puo e ile ya hlahisa ka mokhoa o hlophisehileng diphetoho tsa theknoloji tsa di-capacitor tsa YMIN le mehlala e sebetsang ho fihlelleng bongata bo phahameng ba bokgoni, ESR e tlase, bophelo bo bolelele, le tshepo e phahameng.
Lintlha tsa Bohlokoa
Ka ho amoheloa ka potlako ha disebediswa tsa SiC le GaN dikoloing tse ntjha tsa eneji, polokelo ya eneji ya photovoltaic, di-server tsa AI, phepelo ya motlakase ya diindasteri, le masimo a mang, ditlhoko tsa tshebetso bakeng sa di-capacitor tse tshehetsang di ntse di thatafala le ho feta. Di-capacitor ha e sa le mesebetsi ya tshehetso feela; jwale ke "enjene" ya bohlokwa e etsang qeto ya botsitso, bokgoni le bolelele ba sistimi. Ka boqapi ba thepa, ntlafatso ya sebopeho, le ntlafatso ya tshebetso, YMIN e fihletse dintlafatso tse felletseng ho di-capacitor ho pholletsa le mahlakore a mane: bophahamo, bokgoni, mocheso le botshepehi. Sena se fetohile sa bohlokwa bakeng sa ho kenngwa tshebetsong ka katleho ha dikopo tsa semiconductor tsa moloko wa boraro.

Liphephetso: Ho phahama ha matla a GPU ka tšohanyetso, karabelo ea boemo ba millisecond, le ho senyeha ha bophelo libakeng tse nang le mocheso o phahameng. Tharollo:Li-supercapacitor tsa LIC tse sekwere, khanyetso ea kahare <1mΩ, lipotoloho tse milione e le 'ngoe, le ho tjhaja ka potlako metsotso e 10. Liphetho: Phokotso ea boholo ka 50%-70%, phokotso ea boima ka 50%-60%, le tšehetso ea matla a tlhoro a 15-21kW.
3. Phepelo ea Matla ea Terene ea Infineon GaN MOS480W e Nkela Rubycon ea Japane sebaka. Liphephetso: Mefuta e mengata ea mocheso oa ts'ebetso ho tloha ho -40°C ho isa ho 105°C, maqhubu a maqhubu a phahameng a ripple current. Tharollo: Sekhahla sa ho senyeha ha mocheso o tlase haholo <10%, maqhubu a ripple a mamella 7.8A. Liphetho: Liteko tsa ho qala tse tlase tsa mocheso o tlase tsa -40°C le potoloho ea mocheso o tlase tse nang le sekhahla sa ho atleha sa 100%, li fihlela tlhoko ea bophelo ba indasteri ea terene ea lilemo tse fetang 10.
4. Koloi e Ncha ea MatlaLi-capacitor tsa DC-Link· E tsamaellana le molaoli oa enjene oa 300kW oa ON Semiconductor. Liphephetso: Maqhubu a ho chencha > 20kHz, dV/dt > 50V/ns, mocheso o potolohileng > 105°C. Tharollo: ESL < 3.5nH, nako ea bophelo > lihora tse 10,000 ho 125°C, le 30% ea bokhoni bo ekelitsoeng ka bophahamo ba yuniti. Liphetho: Bokhoni ka kakaretso > 98.5%, matla a feteletseng a fetang 45kW/L, le bophelo ba betri bo eketsehile ka hoo e ka bang 5%. 5. Tharollo ea Pile ea ho Chaja ea GigaDevice ea 3.5kW. YMIN e fana ka tšehetso e tebileng.
Liphephetso: Maqhubu a ho chencha a PFC ke 70kHz, maqhubu a ho chencha a LLC ke 94kHz-300kHz, matla a ho kenya a phahama ho fihlela ho 17A, 'me ho phahama ha mocheso oa mantlha ho ama bophelo ba motlakase haholo.
Tharollo: Sebopeho se bapileng sa li-tab tse ngata se sebelisoa ho fokotsa ESR/ESL. Ha se kopantsoe le lisebelisoa tsa GD32G553 MCU le GaNSafe/GeneSiC, matla a 137W/in³ a fihlelleha.
