Highlights ntawm switching zog mov technology
1 Hloov fais fab mov fais fab ceev ceev.
Kev txhim kho lub zog ceev ntawm kev hloov hluav taws xob, ua rau nws qhov me me thiab lub teeb yuag yog lub hom phiaj uas tib neeg niaj hnub nrhiav. Qhov no tseem ceeb tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob uas siv tau (xws li xov tooj ntawm tes, lub koob yees duab digital, thiab lwm yam). Muaj ntau txoj hauv kev tshwj xeeb los ua kom lub zog hloov pauv hloov pauv: ib qho yog siab zaus. Txhawm rau kom ua tiav lub zog loj ntawm cov khoom siv hluav taws xob, kev ua haujlwm zaus ntawm PWM converter yuav tsum tau nce, yog li txo qhov ntim thiab qhov hnyav ntawm lub zog cia khoom hauv Circuit Court. Qhov thib ob yog daim ntawv thov ntawm piezoelectric transformers. Daim ntawv thov ntawm piezoelectric transformers enables high-frequency zog converters kom lub teeb, me me, nyias, thiab siab zog ceev. Piezoelectric transformers siv cov khoom tshwj xeeb ntawm "voltage-vibration" transformation thiab "vibration-voltage" transformation ntawm piezoelectric ceramic cov ntaub ntawv xa mus rau lub zog. Nws qhov sib npaug Circuit Court yog zoo li ib tug series-parallel resonant circuit, thiab nws yog ib qho ntawm cov kev tshawb fawb hotspots nyob rau hauv lub teb ntawm lub hwj chim hloov dua siab tshiab. Qhov thib peb yog siv hom tshiab capacitor. Txhawm rau txo qhov ntim thiab qhov hnyav ntawm cov khoom siv hluav taws xob hluav taws xob, nws yog ib qho tsim nyog yuav tsum tau sim txhim kho cov kev ua haujlwm ntawm cov capacitors, nce lub zog ceev, thiab kev tshawb fawb thiab tsim cov capacitors tshiab tsim nyog rau cov khoom siv hluav taws xob hluav taws xob thiab lub zog hluav taws xob, uas yuav tsum tau muaj peev xwm loj thiab sib npaug me me. series tsis kam (ESR). , me me, thiab lwm yam.
2. High zaus sib nqus cov khoom.
Ib tug loj tus naj npawb ntawm cov hlau nplaum yog siv nyob rau hauv lub hwj chim system. Cov ntaub ntawv, cov qauv thiab kev ua tau zoo ntawm cov khoom siv hlau nplaum sib nqus sib txawv ntawm cov khoom siv hluav taws xob sib nqus sib nqus. Muaj ntau yam teeb meem uas yuav tsum tau kawm. Cov khoom siv hlau nplaum siv nyob rau hauv high-frequency magnetic Cheebtsam yuav tsum muaj tsawg poob, zoo tshav kub dissipation kev ua tau zoo thiab superior sib nqus. Cov ntaub ntawv sib nqus haum rau megahertz zaus tau nyiam cov neeg nyiam, thiab nanocrystalline mos magnetic cov ntaub ntawv kuj tau tsim thiab siv.
3. Synchronous rectification technology.
Rau qis-voltage, high-tam sim no tso zis soft-switching converters, qhov kev ntsuas los ntxiv txhim kho nws efficiency yog sim los txo cov on-lub xeev poob ntawm tus tes hloov. Piv txwv li, synchronous rectification (SR) thev naus laus zis, uas yog, qhov rov qab kev sib txuas ntawm lub hwj chim MOS raj yog siv los ua qhov hloov diode rau kev kho dua tshiab ntawm Schottky diode (SBD), uas tuaj yeem txo qhov poob ntawm lub raj, yog li txhim kho. Circuit Court efficiency.
4. Electromagnetic Compatibility.
Qhov teeb meem electromagnetic compatibility (EMC) ntawm high-frequency switching fais fab mov muaj nws qhov tshwj xeeb. Lub di / dt thiab dv / dt tsim los ntawm cov khoom siv hluav taws xob semiconductor thaum lub sij hawm hloov cov txheej txheem yuav ua rau muaj zog electromagnetic cuam tshuam thiab kev cuam tshuam kev sib raug zoo, nrog rau cov hluav taws xob muaj zog (feem ntau nyob ze) hluav taws xob. Tsis tsuas yog ua phem rau ib puag ncig electromagnetic ib puag ncig, tab sis kuj ua rau electromagnetic cuam tshuam rau cov khoom siv hluav taws xob nyob ze, thiab tseem tuaj yeem ua rau muaj kev nyab xeeb ntawm cov neeg ua haujlwm nyob ze. Nyob rau tib lub sijhawm, kev tswj xyuas hauv lub zog hluav taws xob hluav taws xob hluav taws xob (xws li lub tshuab hluav taws xob hloov hluav taws xob) kuj tseem tuaj yeem tiv thaiv EMI tsim los ntawm kev hloov pauv thiab lub suab nrov electromagnetic cuam tshuam ntawm qhov chaw thov. Ntau lub tsev kawm ntawv qib siab hauv tsev thiab txawv teb chaws tau tshawb fawb txog kev cuam tshuam ntawm electromagnetic cuam tshuam thiab electromagnetic compatibility ntawm lub hwj chim hluav taws xob circuits, thiab tau ua tiav ntau qhov txiaj ntsig zoo.
