Imashini ya magnetique ifite ibintu bitandukanye biranga inzitizi zitandukanye. Mubisanzwe, impedance ni nto cyane kuri frequency nkeya, kandi impedance irazamuka cyane kuri frequency nyinshi. Iyo hejuru ya signal inshuro nyinshi, biroroshye ko umurima wa magneti ucana. Mubisanzwe, imirongo yerekana ibimenyetso ntabwo ikingiwe. Kurugero, bus ya CAN nkoresha ubu. Iyi mirongo yerekana ibimenyetso iba antene. Iyi antenne idahwema kwakira ibimenyetso bikurikirana cyane. Ibirenze bihindura ibimenyetso nyabyo byoherezwa. Impeta ya magneti irashobora gutambutsa ibimenyetso byingirakamaro mugihe uhagarika ibimenyetso byihuta byihuta.

Mu ntera ndende cyane, reaction ya inductive ikomeza kuba nto, mugihe impedance ari nini, ku buryo iyo ingufu z'ikimenyetso cyihuta cyane zinyuze mu bikoresho bya rukuruzi, zihinduka ubushyuhe kandi zigasohoka, bikabuza kunyura hejuru -ikimenyetso cyinshyi kandi kigahagarika interineti yikimenyetso cyinshi. . Mubisanzwe guhagarika inshuro zingana bifitanye isano na ferrite yo guhagarika. Mubisanzwe, urwego rwo hejuru rukuruzi ya magneti, niko kugabanuka inshuro nyinshi. Nini nini ya ferrite, ningaruka zo guhagarika. Iyo amajwi ahoraho, birebire kandi binini birebire kuruta bigufi kandi binini. Ingaruka zo guhagarika ni nziza, ntoya imbaraga zimbere, ningaruka zo guhagarika.

Iyo uhagaritse uburyo busanzwe bwerekana ibimenyetso, urashobora gutambutsa ibimenyetso cyangwa umurongo wamashanyarazi ukoresheje impeta ya rukuruzi icyarimwe. Kugirango wongere ingaruka, urashobora gukora impinduramatwara nkeya kumpeta ya magneti kugirango wongere inductance kandi wongere imbaraga zo kwinjiza ibimenyetso bisanzwe. Ikimenyetso kibi nta ngaruka.

Huizhou Mingda Precise Electronics Co., Ltd. ifite uruganda ruzobereye mu gukora impeta za EMI zirwanya interineti. Dufite injeniyeri ufite imyaka 20 ya TDK R&D n'uburambe bwo gushushanya. Turashobora guhitamo impeta ya magnetique hamwe nibikorwa byihariye nubunini dukurikije ibyo abakiriya bakeneye bitandukanye kuri EMI anti-interference impeta. ibicuruzwa.
