Lintlha tsa Bohlokoa
Ka ho amoheloa ka potlako ha lisebelisoa tsa SiC le GaN likoloing tse ncha tsa matla, polokelo ea matla a photovoltaic, li-server tsa AI, lisebelisoa tsa motlakase tsa indasteri, le likarolo tse ling, litlhoko tsa ts'ebetso bakeng sa ho tšehetsa li-capacitor li ntse li eketseha. Li-capacitors ha e sa le mesebetsi e tšehetsang feela; hona joale ke "enjene" ea bohlokoa e khethollang botsitso, katleho le bophelo bo bolelele ba tsamaiso. Ka boqapi ba thepa, ntlafatso ea sebopeho, le ntlafatso ea ts'ebetso, YMIN e fihletse ntlafatso e felletseng ea li-capacitor ho litekanyo tse 'ne: bophahamo ba modumo, bokhoni, mocheso le ts'epahalo. Sena e se e le sa bohlokoa bakeng sa ho kengoa tšebetsong ka nepo ha likopo tsa semiconductor tsa moloko oa boraro.
Mathata a Theknoloji
1. AI Server Power Supply Solution · Tšebelisano le Navitas GaN. Mathata: Ho feto-fetoha ha maqhubu a phahameng (> 100kHz), maqhubu a phahameng a ripple current (>6A), le maemo a mocheso o phahameng (>75°C). Tharollo:Letoto la lihlooho tsa IDC3tlase-ESR electrolytic capacitor, ESR ≤ 95mΩ, le nako ea bophelo ea lihora tse 12,000 ho 105°C. Liphello: Phokotso ea 60% ka boholo ba kakaretso, 1% -2% ntlafatso ea katleho, le phokotso ea mocheso oa 10 ° C.
2. NVIDIA AI Server GB300-BBU Backup Power Supply · Ho nka sebaka sa Musashi oa Japane. Mathata: Ho phahama ha matla a GPU ka tšohanyetso, karabelo ea boemo ba millisecond, le ho senyeha ha nako ea bophelo libakeng tse phahameng tsa mocheso. Tharollo:LIC square supercapacitors, khanyetso ea ka hare <1mΩ, li-cycle tse limilione tse 1, le ho tjhaja ka potlako ka metsotso e 10. Liphello: Phokotso ea 50% -70% ka boholo, phokotso ea 50% -60% ea boima ba 'mele, le tšehetso ea matla a phahameng a 15-21kW.
3. Phepelo ea Matla a Seporo sa Infineon GaN MOS480W e Fetang Sebaka sa Rubycon ea Japane. Mathata: Mocheso o pharaletseng oa ho sebetsa oa -40 ° C ho isa ho 105 ° C, maqhubu a phahameng a maqhubu a hona joale. Tharollo: Sekhahla sa ho senyeha ha mocheso o tlase haholo <10%, ho mamella hona joale ke 7.8A. Liphetho: E fetile -40°C liteko tsa potoloho ea mocheso o tlase le mocheso o tlase haholo ka sekhahla sa ho pasa sa 100%, ho fihlela tlhoko ea lilemo tse 10+ tsa indasteri ea literene.
4. Koloi e Ncha ea MatlaLi-capacitors tsa DC-Link· E tsamaellana le selaoli sa enjene sa ON Semiconductor's 300kW. Mathata: Ho fetola maqhubu > 20kHz, dV/dt > 50V/ns, mocheso o phelang > 105°C. Tharollo: ESL <3.5nH, nako ea bophelo> lihora tsa 10,000 ho 125 ° C, le 30% e eketsehile matla ka tekanyo ea yuniti. Liphello: Ho sebetsa hantle ka kakaretso> 98.5%, matla a matla a fetang 45kW/L, le bophelo ba betri bo eketsehile ka hoo e ka bang 5%. 5. GigaDevice 3.5kW Charging Pile Solution. YMIN e fana ka tšehetso e tebileng.
Mathata: PFC switching frequency ke 70kHz, LLC switching frequency ke 94kHz-300kHz, input-side ripple current surges ho feta 17A, mme ho phahama ha mocheso oa mantlha ho ama bophelo ba bophelo haholo.
Tharollo: Ho sebelisoa sebopeho se tšoanang sa li-tab tse ngata ho fokotsa ESR/ESL. Ha e kopantsoe le lisebelisoa tsa GD32G553 MCU le GaNSafe/GeneSiC, ho fihlella matla a matla a 137W/in³.
Liphello: Ts'ebetso ea tlhōrō ea tsamaiso ke 96.2%, PF ke 0.999, 'me THD ke 2.7%, e finyellang botšepehi bo phahameng le litlhoko tsa bophelo ba lilemo tse 10-20 tsa liteishene tsa likoloi tsa motlakase.
Qetello
Haeba u thahasella lits'ebetso tsa morao-rao tsa li-semiconductors tsa moloko oa boraro 'me u labalabela ho ithuta kamoo tlhahiso ea capacitor e ka ntlafatsang ts'ebetso ea sistimi le ho nkela mabitso a machaba sebaka, ka kopo etela YMIN booth, C56 ho Hall N5, bakeng sa puisano e qaqileng ea tekheniki!
