Ngokuthuthukiswa kobuchwepheshe bokuhlunga okuxhunyaniswa kwamandla, ubuchwepheshe bokuhlunga busebenza kakhulu ekucindezelweni ukuphazamiseka kwe-electromagnete, ikakhulukazi kwi-EMI Signal yokushintshwa kwamandla, okungadlala indima enhle ekuphazanyisweni nasekuphazanyisweni kwemisebe. Izimpawu zokuphazamiseka kweModi yeModi kanye nezimpawu ezijwayelekile zokuphazanyiswa kwamamodi zingamelela zonke izinkomba zokuphazamiseka kokuvunyelwa kwamandla.
Owangaphambili ubhekisela esigcawini sokuphazanyiswa okudluliselwe phakathi kwezintambo ezimbili, okungokwangowokuphazamiseka kokuvumelanisa futhi kubonakaliswa imvamisa ephansi, ukungenelela okuncane kwe-electromagnete. Lokhu okugcina kubhekiswa ekudluliseleni amasiginali wokuphazamisa phakathi kocingo nendawo ebiyelwe (umhlaba), okungokwengeziwe, futhi kubonakaliswa imvamisa ephezulu, ukuphazamiseka okukhulu kwe-electromagnetic.
Ngokusekelwe ekuhlaziyweni okungenhla, isiginali ye-EMI ingalawulwa ngaphansi kweleveli yomkhawulo echazwe amazinga e-EMI ukufeza inhloso yokunciphisa ukuphazamiseka kwe-conduction. Ngaphezu kokucindezelwa okusebenzayo kwemithombo yokuphazanyiswa, izihlungi ze-EMI ezifakwe kwimibuthano yokufaka nokukhipha kwamandla okushintsha amandla okushintshana nayo iyindlela ebalulekile yokucindezela ukuphazanyiswa kwe-electromagnete. Imvamisa evamile yokusebenza kwamadivayisi we-elekthronikhi imvamisa phakathi kwe-10mhz no-50mhz. Iningi le-EMC Izinga lemikhawulo yeleveli ephansi ye-10 MHZ, ye-High Frequency switch Power Supply Emi Isiginali ye-EMI, inqobo nje uma ukukhetha kwe-EMI yenethiwekhi kulula ngaphandle, kungatholakali kuphela Inhloso yokunciphisa ubukhulu be-high-frequency evamile-mode yamanje, futhi inganelisa umphumela wokuhlunga wemithetho ye-EMC.
Umgomo wokuqamba wesixhumi sikagesi sokuhlunga ususelwa kwisimiso esingenhla. Kukhona inkinga yokuphazamiseka okuhambisanayo phakathi kwemishini kagesi namandla kagesi naphakathi kwemishini ehlukahlukene kagesi, nesixhumi se-Filter Electrical Connectical kuyinto ekhethwe kahle yokunciphisa ukuphazanyiswa. Njengoba i-PIN ngayinye yesixhumi sokuhlunga inesihlungi esiphansi, i-PIN ngayinye ingahlunga ngempumelelo imodi ejwayelekile yamanje. Ngaphezu kwalokho, isixhumi sikagesi sokuhlunga futhi sinokuhambisana okuhle, usayizi waso esibonakalayo kanye nosayizi wokwakheka kanye nesixhumi esijwayelekile sikagesi okufanayo, ngakho-ke, bangathathelwa indawo ngokuqondile.
Ngaphezu kwalokho, ukusetshenziswa kwesixhumi samandla okuhlunga kubuye kube nomnotho omuhle, okuyinto ikakhulukazi ukuthi isixhumi samandla esihlungi sidinga ukufakwa kuphela ethekwini lecala elivikelwe. Ngemuva kokuqeda ukuphazamiseka kwamanje kukhebula, umqhubi wesifundo ngeke esazwa uphawu lokuphazanyiswa, ngakho-ke unokusebenza okuzinzile kunekhebula elivikelwe. Isixhumi sikagesi sokuhlunga asinazo izidingo eziphakeme zokuxhumeka kokuphela kwekhebula, ngakho-ke akudingi ukusebenzisa ikhebula elivikelwe eliphezulu lonke, okubuye kubonise umnotho walo kangcono.
