Inzira rusangebivuze ko ibishishwa bibiri bikomerekejwe kumurongo umwe wicyuma, hamwe no guhinduranya, umubare wimpinduka nicyiciro kimwe. Bikunze gukoreshwa muguhindura ibikoresho byamashanyarazi kugirango bishungure-uburyo busanzwe bwa electromagnetic interineti yerekana ibimenyetso, EMI muyunguruzi ikoreshwa muguhagarika amashanyarazi yumuriro utangwa numurongo wihuta wihuta uturuka hanze. Uburyo busanzwe bwo kwinjizamo kwinjiza ingufu za module mubisanzwe ni ukugabanya imirasire hamwe numuvuduko mwinshi urusaku rusanzwe. Nyamara, inductance nini isanzwe-isanzwe ifite ingaruka nziza zo guhagarika imvururu nkeya, kandi inshuro nyinshi zishobora kuba mbi, ariko ibyiyumvo bito bigira ingaruka mbi zo guhagarika imvururu nke.

Ifite ingaruka zigaragara zo guhagarika urusaku rusanzwe. Ihame ryakazi ni uko iyo uburyo busanzwe bugezweho bwanyuze mubice, induction ya inductors zombi ziruzuzanya. Ariko kubera urusaku rwuburyo butandukanye, induction zombi zingana no gufata itandukaniro, agaciro ka inductance kagabanuka, kandi ingaruka zo guhagarika zizacika intege.

Ingano yuburyo busanzwe inductance izagira ingaruka kumikorere ya EMC. Igikorwa nyamukuru nugutandukanya ibimenyetso byuburyo busanzwe no guhuza uburyo busanzwe bwo kwivanga, bityo bikagabanya ingaruka kumashanyarazi. Irashobora kandi kugabanya ibimenyetso byimbere byimbere kandi bikagabanya ingaruka kuri gride. Nyamara, inductance nini isanzwe-isanzwe ifite ingaruka nziza zo guhagarika imvururu nkeya, kandi inshuro nyinshi zishobora kuba mbi, ariko ibyiyumvo bito bigira ingaruka mbi zo guhagarika imvururu nke.

Ibyo dusanzwe dukoresha kumpera yanyuma yingufu zingufu ni x ubushobozi, y ubushobozi hamwe nuburyo busanzwe bwa inductance. Ubushobozi bufite inzitizi nke kubimenyetso, bikora nkibimenyetso byuzuzanya. Inductance ni inzitizi nyinshi kubimenyetso kandi igira uruhare mukugaragaza no kwinjiza ibimenyetso byihuta byihuta.

Kwivanga hagati yimirongo ibiri yingufu kubutaka byitwa uburyo busanzwe bwo kwivanga, naho guhuza imirongo ibiri yingufu byitwa itandukaniro ryuburyo butandukanye. Iyo inductance na capacitance bihujwe mukayunguruzo, ingaruka zo kuyungurura nibyiza, hamwe na bande yumurongo aho inductance na capacitance bigira uruhare. Kandi bitandukanye. Y capacitor Y na capacitor Y bigira uruhare mukuyungurura uburyo busanzwe bwo kwivanga, kandi X capacitor ikora cyane nkikimenyetso kigufi cyumuzunguruko, kugabanya inzira inyuramo ibimenyetso bitandukanye byerekana inzira, bityo bikagabanya ihungabana ryatewe nibintu bya parasitike muri umuzunguruko no gutera imyuka myinshi.

Iyo inductance cyangwa capacitance yakuwe mubishushanyo, igice gisigaye kizakomeza gukora, ariko ingaruka zizaba mbi cyane. Muri rusange nukuvuga, uko binini-bisanzwe-impedance, nibyiza. Iyo uhisemo inductor isanzwe-ihitamo, guhitamo ahanini bishingiye kumurongo wa impedance. Muri icyo gihe, hagomba kwitonderwa ingaruka ziterwa nuburyo butandukanye kubimenyetso.
