Hloov fais fab mov kev ruaj ntseg capacitor hloov, lub peev xwm sib txawv muaj qhov cuam tshuam?
Hloov cov khoom siv hluav taws xob hauv kev hloov cov khoom siv hluav taws xob kev nyab xeeb, qhov cuam tshuam ntawm lub peev xwm sib txawv kuv xav tias los ntawm ob yam ntawm qhov cuam tshuam no:.
Los ntawm EMC kev ua tau zoo ntawm qhov pom, yuav tsum muaj kev cuam tshuam, tab sis nws nyuaj rau hais tias qhov cuam tshuam loj npaum li cas; - Los ntawm cov haujlwm tseem ceeb ntawm cov khoom siv hluav taws xob, yuav tsum muaj kev cuam tshuam me ntsis, lossis nws tuaj yeem hais tias yuav tsis muaj kev cuam tshuam.
Los ntawm qhov kev xav ntawm lub hauv paus kev ua haujlwm ntawm cov khoom siv hluav taws xob, nws yuav tsum tsis txhob muaj kev cuam tshuam ntau, lossis nws tuaj yeem hais tias yuav tsis muaj kev cuam tshuam; Lub luag hauj lwm ntawm kev ruaj ntseg capacitors nyob rau hauv lub switching fais fab mov nyob rau hauv kev ruaj ntseg capacitors feem ntau muaj X capacitance thiab Y capacitance, X capacitance yog ntsia nruab nrab ntawm lub L, N, Y capacitance feem ntau ntsia nruab nrab ntawm L-PE los yog N-PE.
Lub luag haujlwm ntawm cov capacitor no feem ntau yog rau kev lim dej. Ntawm ib sab, nws yuav lim tawm ib feem ntawm kev cuam tshuam los ntawm sab nraud, ntawm qhov tod tes, nws tseem tuaj yeem lim tawm qhov cuam tshuam ntawm kev hloov hluav taws xob hloov hluav taws xob ntawm daim phiaj hluav taws xob, tau kawg, cov ntxaij lim dej no yuav tsum yog lwm yam khoom siv, xws li hom hom inductors, uas yog EMC.
Raws li cov capacitors txuas ncaj qha rau hauv daim phiaj, thiab cov kab sib chaws txuas nrog ntau cov khoom siv hluav taws xob lossis khoom siv. Yog li ntawd, yuav muaj surges, pab pawg pulses los yog voltage variations thiab lwm yam hnyav nyob rau hauv daim phiaj.
Cov capacitors raws li yuav tsum tau muaj ntawv pov thawj kev nyab xeeb, txwv tsis pub yuav muaj kev nyab xeeb.
Raws li kev soj ntsuam saum toj no, yog tias cov capacitors hloov pauv, cov hloov capacitors yuav tsum muaj ntawv pov thawj kev nyab xeeb.
Yog tias lub peev xwm sib txawv, nws yuav muaj kev cuam tshuam rau EMC kev ua tau zoo, tab sis nws yog ib qho nyuaj hais tias muaj kev cuam tshuam ntau npaum li cas, qhov muaj peev xwm sib txawv tsis loj, ces nws yuav tsis muaj kev cuam tshuam ntau. Tab sis qhov kev ua haujlwm tseem ceeb ntawm kev hloov hluav taws xob hloov kuv tsis xav tias nws yuav muaj kev cuam tshuam.
