Ndi chitukuko cha ukadaulo wosefera wolumikizira mphamvu, ukadaulo wosefera ndiwothandiza kwambiri kupondereza kusokoneza kwamagetsi, makamaka kwa EMI siginecha yosinthira magetsi, yomwe imatha kutenga gawo labwino pakusokoneza komanso kusokoneza ma radiation.Zizindikiro zosokoneza zamitundu yosiyanasiyana ndi zizindikiro zosokoneza wamba zimatha kuyimira zizindikiro zonse zosokoneza pamagetsi.

Zakale makamaka zimatanthawuza chizindikiro chosokoneza chomwe chimaperekedwa pakati pa mawaya awiri, omwe ndi a symmetry kusokoneza ndipo amadziwika ndi mafupipafupi otsika, ang'onoang'ono osokoneza matalikidwe ndi kusokoneza kochepa kopangidwa ndi electromagnetic.Chotsatirachi makamaka chimatanthawuza kufalikira kwa zizindikiro zosokoneza pakati pa waya ndi mpanda (nthaka), yomwe ili ya kusokoneza kwa asymmetric, ndipo imadziwika ndi maulendo apamwamba, kusokoneza kwakukulu ndi kusokoneza kwakukulu kopangidwa ndi electromagnetic.

Kutengera kusanthula pamwambapa, chizindikiro cha EMI chikhoza kuwongoleredwa pansi pa malire omwe amanenedwa ndi miyezo ya EMI kuti akwaniritse cholinga chochepetsa kusokoneza kwa conduction.Kuphatikiza pakupondereza koyenera kwa magwero osokoneza, zosefera za EMI zomwe zimayikidwa muzolowera ndi zotulutsa zamagetsi osinthira ndi njira yofunikira yopondereza kusokoneza kwamagetsi.Ma frequency ogwiritsira ntchito pazida zamagetsi nthawi zambiri amakhala pakati pa 10MHz ndi 50MHz.Ambiri a EMC muyezo wa otsika conduction kusokoneza mlingo malire a 10 MHZ, kwa mkulu pafupipafupi lophimba mphamvu kotunga EMI chizindikiro, bola ngati kusankha maukonde dongosolo ndi losavuta EMI fyuluta kapena decoupling EMI fyuluta dera ndi yosavuta, osati kukwaniritsa. cholinga chochepetsera kuchulukira kwa ma frequency amtundu wamba, komanso kutha kukwaniritsa kusefa kwa malamulo a EMC.

Mfundo yopangira fyuluta cholumikizira magetsi imachokera pa mfundo yomwe ili pamwambayi.Pali vuto la kusokonezana pakati pa zida zamagetsi ndi magetsi komanso pakati pa zida zosiyanasiyana zamagetsi, ndipo cholumikizira magetsi chosefera ndi njira yabwino yochepetsera kusokoneza.Popeza pini iliyonse ya cholumikizira cha fyuluta ili ndi fyuluta yotsika, pini iliyonse imatha kusefa njira wamba yomwe ilipo.Komanso, cholumikizira magetsi fyuluta alinso ngakhale zabwino, mawonekedwe ake kukula ndi mawonekedwe kukula ndi wamba cholumikizira magetsi chimodzimodzi, kotero, iwo akhoza mwachindunji m'malo.

Kuphatikiza apo, kugwiritsa ntchito cholumikizira mphamvu zosefera kumakhalanso ndi chuma chabwino, chomwe makamaka chifukwa cholumikizira mphamvu ya fyuluta chimangofunika kukhazikitsidwa padoko lamilandu yotetezedwa.Pambuyo pochotsa kusokoneza panopa mu chingwe, woyendetsa sadzamvanso chizindikiro chosokoneza, choncho amakhala ndi ntchito yokhazikika kuposa chingwe chotetezedwa.Cholumikizira magetsi chosefera sichikhala ndi zofunika kwambiri pakulumikiza komaliza kwa chingwe, chifukwa chake sichiyenera kugwiritsa ntchito chingwe chotetezedwa chapamwamba konse, chomwe chikuwonetsanso chuma chake chabwino.
