EMC(Electro Magnetic Compatibility): electromagnetic compatibility, is the interaction of electrical and electronic devices with their electromagnetic environment and other devices. Tag nrho cov tshuab hluav taws xob muaj lub peev xwm tso hluav taws xob hauv hluav taws xob. With the proliferation of electronic devices in everyday life - TVS, washing machines, electronic ignition lights, traffic lights, cell phones, ATMs, anti-theft tags, to name a few - there is a high likelihood that devices will interfere with each other.
EMC suav nrog peb lub ntsiab lus hauv qab no:
EMC (electromagnetic Compatibility) = EMI (electromagnet cuam tshuam) + EMS (Electromagnetic Kev Tiv Thaiv) + Kev Tiv Thaiv Electromagnetic Ib puag ncig
1.EMI(Electro Magnetic Interference): electromagnetic interference, that is, the equipment or system in a certain environment should not generate electromagnetic energy exceeding the requirements of the corresponding standards during normal operation. EMI is a product of "speed", the operating frequency of product IC will become higher and higher, and the EMI problem will become more and more serious; Txawm li cas los xij, tus qauv xeem tsis tau so, tab sis tsuas yog ua kom nruj;
3. Electromagnetic ib puag ncig: kev ua haujlwm ib puag ncig ntawm cov txheej txheem lossis khoom siv.
Ntawm no, peb siv ib daim duab qub ua piv txwv yooj yim ntawm qhov emi zoo li. Ntawm sab laug, koj yuav pom ib daim duab coj los ntawm lub TV qub. Txij li nws tsis tsim rau EMI, cov TVS laus yog qhov ua tau zoo heev rau kev ua tiav tshwm sim los ntawm EMI thiab nws ib puag ncig. Daim duab nyob sab xis qhia tau cov txiaj ntsig ntawm qhov kev cuam tshuam no.
EMC tiv thaiv kev tsim qauv
1, Reduce the interference signal at the source - for example, the shorter the rise/fall time of the digital signal, the more high-frequency spectrum it contains; Feem ntau, ntau dua cov zaus, qhov yooj yim nws yog rau ob peb tus txais. Yog tias peb xav txo cov kev cuam tshuam los ntawm cov cim digital, peb tuaj yeem ua kom ntev nce / caij nplooj zeeg lub sijhawm ntawm cov paib digital. Txawm li cas los xij, qhov premise yog kom ntseeg tau tias txoj haujlwm ib txwm ntawm cov cuab yeej tau txais lub teeb liab digital.
3. Nce thaj chaw hauv av ntawm cov ntsiab lus tseem ceeb thiab cov khoom siv yuav tsum tau ua kom tiav.
Disen electronics co., Ltdyog cov lag luam qib siab ua lag luam R & D, Tsim, Ntau Lawm, Kev Muag Khoom thiab Kev Pabcuam, tsom mus rau R & D thiab tsim khoom ntawm kev lag luam,Tsheb Zaub, Kov Vaj Huam Sib Luagthiab cov khoom lag luam muag khoom siv kho tshiab, uas tau siv dav hauv cov cuab yeej kho mob, cov khoom siv roj tsim, kev siv internet thiab cov tsev ntse. Peb muaj kev tshawb fawb nplua nuj, kev loj hlob thiab tsim kev kawm hauv TFT LCD,Muaj Zaub, Tsheb Zaub, Ko KOV VAJ HUAM SIB LUAG, THIAB NIAM TXIV, thiab yog rau cov thawj coj ua lag luam.
