LLC hloov cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hloov pauv zoo ib yam muaj qhov sib txawv tseem ceeb hauv ntau yam
Circuit Court qauv thiab kev ua haujlwm
LLC Switching Power Supply:
Cov qauv Circuit Court: LLC hloov hluav taws xob txais yuav LLC resonant topology Circuit Court, uas muaj cov inductor L, capacitor C, thiab transformer T. Cov inductor L, capacitor C, thiab transformer yog txuas nrog hauv series, thiab cov zis voltage yog hloov los ntawm kev hloov ib nrab choj hloov zaus.
Lub hauv paus ntsiab lus ua haujlwm: LLC hloov hluav taws xob ua haujlwm raws li lub hauv paus ntsiab lus ntawm resonance, los ntawm kev kho qhov hloov zaus hloov pauv lub xeev ua haujlwm ntawm lub resonant Circuit Court, yog li ua tiav cov kev cai voltage. Qhov no resonant converter tuaj yeem tswj xyuas qhov zoo ntawm kev tswj hwm tus yam ntxwv nyob rau hauv ntau yam ntawm input voltage thiab load variations.
Ordinary switch power supply:
Cov qauv hauv Circuit Court: Cov khoom siv hluav taws xob hloov pauv ib txwm muaj xws li cov khoom siv hluav taws xob rectifier, lim circuits, hloov raj, transformers, thiab lwm yam. Lawv cov qauv hauv Circuit Court yog qhov nyuaj thiab muaj ntau haiv neeg, thiab sib txawv circuit topologies yog tsim los ntawm cov ntawv thov tshwj xeeb.
Lub hauv paus ntsiab lus ua haujlwm: Cov khoom siv hluav taws xob hloov pauv hloov pauv tswj kev sib kis thiab hloov pauv ntawm hluav taws xob hluav taws xob los ntawm kev hloov pauv sai ntawm cov raj hloov pauv, txhawm rau kho cov zis voltage thiab tam sim no. Cov kev hloov pauv uas muaj xws li pulse width modulation (PWM) thiab pulse zaus modulation (PFM).
2, Kev ua haujlwm zoo
Kev ua tau zoo:
LLC Hloov Cov Khoom Siv Hluav Taws Xob: Vim yog siv cov thev naus laus zis hloov pauv hloov pauv, LLC hloov cov khoom siv hluav taws xob tuaj yeem txo lub zog poob thaum lub sijhawm tawm tswv yim- tso zis hloov pauv, yog li muaj kev hloov pauv siab. Nyob rau tib lub sijhawm, MOS transistor ntawm LLC resonant converter tuaj yeem ua tiav xoom voltage tig- rau (ZVS), thiab lub diode tuaj yeem ua tiav xoom tam sim no tig tawm (ZCS), ntxiv txo qhov kev poob qis.
Ordinary Switching Power Supply: Txawm hais tias cov khoom siv hluav taws xob hloov pauv zoo tib yam kuj muaj kev ua haujlwm siab, lawv cov kev ua haujlwm yuav qis dua me ntsis piv rau LLC hloov cov khoom siv hluav taws xob. Tshwj xeeb tshaj yog nyob rau hauv siab - daim ntawv thov fais fab, qhov kev hloov pauv ntawm cov khoom siv hluav taws xob hloov pauv zoo ib yam tuaj yeem hais tau ntau dua.
Lub zog ceev:
LLC Switching Power Supply: Vim yog lub resonant topology Circuit Court, lub transistor hloov pauv ua haujlwm ntawm cov zaus siab, yog li qhov ntim ntawm LLC hloov hluav taws xob tuaj yeem ua kom me dua thiab lub zog ceev dua. Qhov no ua rau LLC hloov cov khoom siv hluav taws xob muaj txiaj ntsig zoo hauv cov xwm txheej uas yuav tsum muaj lub zog loj.
Hom hloov pauv hloov hluav taws xob: Lub zog ceev ntawm qhov hloov pauv hloov pauv hloov hluav taws xob yog qhov tsawg, tshwj xeeb tshaj yog nyob rau hauv siab - cov ntawv siv hluav taws xob, uas yuav xav tau lub ntim loj dua kom haum rau ntau yam khoom thiab cov khoom siv hluav taws xob.
Electromagnetic cuam tshuam (EMI):
LLC Switching Power Supply: LLC hloov cov khoom siv hluav taws xob muaj cov yam ntxwv EMI tsawg, uas tuaj yeem txo kev cuam tshuam nrog lwm yam khoom siv hluav taws xob. Qhov no yog vim tus tsim ntawm nws resonant conversion Circuit Court, uas zoo suppresses electromagnetic hluav taws xob thaum lub sij hawm switching txheej txheem.
Ordinary Switching Power Supply: Cov khoom siv hluav taws xob hloov pauv ib txwm tuaj yeem ua rau muaj kev cuam tshuam ntawm electromagnetic cuam tshuam thaum hloov cov txheej txheem, thiab kev ntsuas ntxiv yuav tsum tau coj los txo EMI qib.
3, Daim ntawv thov teb
LLC Hloov Cov Khoom Siv Hluav Taws Xob: Vim nws cov kev ua haujlwm siab, lub zog siab ceev, thiab qis EMI, LLC hloov cov khoom siv hluav taws xob tau dav siv hauv siab -kawg teb xws li cov khoom siv hluav taws xob, khoom siv sib txuas lus, cov servers, thiab cov khoom siv hluav taws xob.
Ordinary Switching Power Supply: Cov khoom siv hluav taws xob hloov pauv tau siv dav hauv ntau yam khoom siv hluav taws xob, xws li khoom siv hauv tsev, khoom siv computer, khoom siv teeb pom kev zoo, thiab lwm yam. Nws muaj ntau yam kev siv, tab sis tej zaum yuav tsis ua tau raws li qhov yuav tsum tau ua hauv qhov tshwj xeeb siab -qhov kawg daim ntawv thov.
