Yuav ua li cas kom txo qis cov kev poob ntawm kev ua kom tiav los ntawm kev ua si hauv kev sib txuas lus Circuit Court?

一, kev txhim kho cov cuab yeej ua kom zoo dua: meej phim ntawm tus yam ntxwv tsis siv
1. Xaiv cov hluav taws xob qis qis
Hauv qhov qis - voltage dc fais fab mov scenarios, cov kev xaiv schiodes yog qhov kev xaiv tshwj xeeb vim yog 0.15-0.4.45V. Lub zog siv hluav taws xob ntawm qee yam chaw nres tsheb admts mbr2045 acc Rau cov ntawv thov siab dua, silicon carmide schottky diodes (Siic) tseem muaj qhov ntau dua ntawm 200kHz, uas yog 40% qis dua li silicon pab kiag li lawm.
2. Cov ntaub ntawv rov qab sai sai
Hauv kev hloov pauv theem nrab ntawm lub tshuab hloov hluav taws xob, qhov rov ua dua tshiab txo qhov poob los ntawm kev thim rov qab lub sijhawm rov qab (TRR =50-200 ns). Ib hom 48v / 12V kev sib txuas lus fais fab kev sib txuas lus C3D060AA Siic Mosfet Rectification Txheej Txheem, sib xyaw ua ke nrog FD kom ua tiav lub sijhawm rov qab<35ns, making the power efficiency exceed 96%, which is 4 percentage points higher than the traditional silicon scheme.
3. Kev Siv Dej Kub Tsim
Hauv kev tsis ncaj ncees ntawm photodiodes, voltage poob thiab kub txav ua rau kev ua kom muaj kev nkag siab. Siv ntawm40QL022 sensor thiab voltage divider resistor network los tsim cov nyiaj them rov qab los tsim kev them nqi hluav taws xob, PD bias voltage fluctuative<0.05V within the temperature range of -40 ℃ to+85 ℃, the stability of receiving sensitivity is improved by 0.3dB, and the transmission distance is extended by 2.3 kilometers.
2, Circuit Court qib: hloov kho lub zog hloov dua siab tshiab
1. Kev tawg hauv synchron rectification thev naus laus zis
Tso cai DIode Diode Daws muaj kev ruaj ntseg ntawm 0.7v, thaum synchron recectification siv Mosfets tsis yog ua tiav kev sib raug zoo ntawm<5m Ω. A certain type of AI server power supply adopts a synchronous rectification scheme controlled by LTC4359, with a voltage drop of only 56mV at 3A current and a full load efficiency of 98.5%, which is 6 percentage points higher than the diode scheme. The key design points include:
Lub sijhawm tswj hwm tuag: ua tiav lub sijhawm 50ns uas muaj lub sijhawm dhau los ntawm TPS28750 tsav tsheb kom tsis txhob muaj hla hla kev
Parasitic Parameter Optimization: Siv 0402 ntim tiv thaiv kom txo qis cov hmoov txhuas thiab txo qis oscillation
Teeb tsa optimization: tswj qhov kev ncua deb ntawm synchronousious ntawm synchronousti tranchoror thiab qhov kev txhaj tshuaj thib ob ntawm cov transformer tsis pub dhau 2 hli los txo qhov kev cuam tshuam ntawm cov xaim hluav taws xob
2. Cov choj nquag Archify Architecture
Daim diDe diode Indianction generates ib 1.4v voltage poob hauv PFC circuits, ua rau muaj kev poob siab. Lub Potem ncej Choj Dawb Recucology txo kev puas tsuaj los ntawm 60% los ntawm kev tshem tawm cov tswv yim ntawm cov choj. Qee hom kev sib txuas lus ntawm 6kW siv CAS120m12B12BMM2 (ua tiav qhov kev ua haujlwm ntawm CCM
3. RC Txom Network Kev Ua Kom Txhim Kho
Qhov hluav taws xob hluav taws xob hluav taws xob tsim los ntawm kev rov qab rov qab los ntawm rectifier dodes ua rau poob ntxiv. Txhim kho RC tsis muaj peev txheej siv cov qauv ntsuas:
Ntsuas cov oscillation zaus F0 (piv txwv li. 1.2 mhz)
Lub capacel capacitor c txo qhov zaus rau 0.6mhz
Xam cov patasitic inductance l =1 / (4 π² F0 ² c)
Txiav txim siab qhov damping tsis kam raws r=√ (l / c) (tus nqi raug 10-100 ω)
Ib hom photovoltaic inverter txo cov diode poob ntawm 8.2W rau 5.7w rau 5.7 mais kev ua tau zoo los ntawm 2.8% los ntawm hom no.
3, system qib kev sib koom tes: tsim lub zog ecosystemle
1. Muab faib siv hluav taws xob fais fab
Nyob rau hauv cov chaw tsim hluav taws xob loj, ib lub tsheb npav 48V yog siv nyob rau hauv kev sib txuas nrog faib hluav taws xob module (PSU) coj cov rectification txuas ze rau tus nqi thauj khoom. Ib hom kev sib tw supercomputer txo qis ntev} Kev pab ntawm cov duab hluav taws xob ntev ntawm 94.2%, uas yog 7 feem pua ​​cov ntsiab lus siab dua cov lis kev cai 400v ac accontacture.
2. Txawj Ntse Lub Siab Lub Siab poob kev tswj
Lub Ti TPS2419 nti hloov kho lub rooj vag voltage ntawm synchronous Mos tensistor los ntawm kev saib xyuas qhov tseeb hauv qhov tseeb yog tswj hwm ntawm qhov muaj txiaj ntsig zoo. Hauv qee yam ntawm 5G chav nres tsheb hluav taws xob cov khoom siv hluav taws xob, cov thev naus laus zis txhim kho lub teeb txuag hluav taws xob los ntawm 8%, thiab txo cov pa roj carbon monissions txhua xyoo los ntawm 12 tons.
3. Cov twital ntxaib ua kom zoo
Lub Tri LTSPICE Simulation Platform, sib xyaw nrog tshuab kev kawm algorithms, tuaj yeem twv tau kev faib cov diode poob raws li kev ua haujlwm sib txawv. Lub zog muab kev tsim qauv ntawm qee hom submarine fiber ntau optic Cable ua kom tiav cov khoom siv ntawm cov thev naus laus zis ntawm 40% thiab txij nkawm los ntawm 40% nyob rau 10-xyoo patpespan.
