Ngophuhliso lwetekhnoloji yokucoca isidibaniso samandla, itekhnoloji yokucoca iyasebenza kakhulu ekucinezeleni uphazamiseko lwe-electromagnetic, ngakumbi kumqondiso we-EMI wokutshintsha umbane, onokudlala indima entle ekuqhubeni uphazamiseko kunye nokuphazamiseka kwemitha. Iimpawu zokuphazamiseka kwemowudi eyahlukileyo kunye neempawu zokuphazamiseka kwemowudi eqhelekileyo zinokubonisa zonke iimpawu zokuphazamiseka kokuqhutywa kunikezelo lwamandla.
Eyangaphambili ibhekisa ikakhulu kumqondiso wophazamiseko ogqithiselwe phakathi kweengcingo ezimbini, ezizezokuphazamiseka kwe-symmetry kwaye ziphawulwa ngamaza aphantsi, i-amplitude encinci yokuphazamiseka kunye nokuphazamiseka okuncinci okwenziwe ngumbane wombane. Le yokugqibela ibhekisa ikakhulu kukuhanjiswa kwemiqondiso yophazamiseko phakathi kocingo kunye nendawo ebiyelweyo (umhlaba), eyeyokuphazamiseka kwe-asymmetric, kwaye ibonakaliswa ngamaza aphezulu, i-amplitude enkulu yokuphazamiseka kunye nokuphazamiseka okukhulu kwe-electromagnetic.
Ngokusekelwe kuhlalutyo olungentla, isignali ye-EMI inokulawulwa ngaphantsi kwenqanaba lomda elichazwe yimigangatho ye-EMI ukufezekisa injongo yokunciphisa ukuphazamiseka kokuqhuba. Ukongeza kuxinzelelo olusebenzayo lwemithombo yokuphazamiseka, izihluzi ze-EMI ezifakwe kwigalelo kunye neesekethe eziphumayo zobonelelo lwamandla okutshintsha zikwayindlela ebalulekileyo yokucinezela ukuphazamiseka kwe-electromagnetic. Amaxesha aqhelekileyo okusebenza kwezixhobo zombane aqhele ukuba phakathi kwe-10MHz kunye ne-50MHz. Uninzi lomgangatho we-EMC womgangatho ophantsi wokuphazamiseka wokuphazamiseka kwe-10 MHZ, unikezelo lwamandla ombane aphezulu frequency EMI, okoko nje ukhetho lwesakhiwo sothungelwano lulula ngokwentelekiso EMI lokucoca okanye ukudityaniswa kwesekethe yokucoca i-EMI kulula, kungekuphela nje ukuphumeza injongo yokunciphisa ubukhulu be-high-frequency common-mode yangoku, nako kunokwanelisa isiphumo sokucoca i-EMC.
Umgaqo woyilo wokucoca umbane wokucoca usekelwe kulo mgaqo ungasentla. Kukho ingxaki yokuphazamiseka phakathi kwezixhobo zombane kunye nonikezelo lwamandla kunye naphakathi kwezixhobo ezahlukeneyo zombane, kwaye isiqhagamshelanisi sombane sokucoca lukhetho olufanelekileyo lokunciphisa ukuphazamiseka. Kuba isikhonkwane ngasinye sesihluzi sinesihluzo esisezantsi, isikhonkwane ngasinye singahluza ngokufanelekileyo indlela eqhelekileyo yangoku. Ukongeza, isiqhagamshelanisi sombane esihluza sikwanokuhambelana okuhle, ubungakanani bayo bojongano kunye nobungakanani bemilo kunye nesinxibelelanisi esiqhelekileyo sombane ngokufanayo, ngoko ke, zinokutshintshwa ngokuthe ngqo.
Ukongeza, ukusetyenziswa kwesixhumi samandla okucoca kwakhona kunoqoqosho oluhle, oluyininzi ngenxa yokuba isixhumi samandla okucoca sifuna ukufakwa kuphela kwi-port yecala elikhuselekileyo. Emva kokuphelisa ukuphazamiseka kwangoku kwikhebula, umqhubi akayi kuphinda azive isignali yokuphazamiseka, ngoko unomsebenzi ozinzile ngaphezu kwekhebula elikhuselekileyo. Isixhumi sombane sokucoca asinazo iimfuno eziphezulu zokuphela koqhagamshelo lwentambo, ngoko ke akufuneki ukuba kusetyenziswe intambo ekhuselekileyo ekumgangatho ophezulu, nto leyo ebonisa ngakumbi uqoqosho lwayo olungcono.
