Bitewe nibiranga amashanyarazi yo guhinduranya, biroroshye gutera amashanyarazi yo guhinduranya kugirango atange interhanaGnoric neza. Nka injeniyeri utanga amashanyarazi, injeniyeri ya electronagnetique, cyangwa injeniyeri ya PCB, ugomba gusobanukirwa ibitera ibibazo byo guhuza electagnetic kandi wakemuye ingamba, cyane cyane injeniyeri zifatika zikeneye kwirinda kwaguka kw'ibibanza byanduye. Iyi ngingo igena ahanini ingingo nyamukuru zamashanyarazi.

.

. Mugihe kimwe, ibimenyetso bito byerekana bigomba kuba kure yimirongo minini ya di / DT yerekana ibimenyetso byinshi kugirango wirinde karoti inductive. Nibyiza kutajya munsi yikimenyetso kinini cya DV / DT mugihe ibimenyetso bito byerekana ibimenyetso. Niba inyuma yibimenyetso bito byerekana ibimenyetso bifatika (ubutaka bumwe), ikimenyetso cyurusaku hamwe nacyo gishobora kugabanuka.

17. Nibyiza gushira hasi hamwe inyuma yiyi dv / dt yerekana ibimenyetso binini (harimo inkingi ya c / d hand of the radices. Mubisanzwe Ibi birashobora kugabanya EMI. Twabibutsa ko ubutaka buto butagomba guhuzwa nubu butaka bukingira, bitabaye ibyo bizashyiraho kwivanga cyane. Ibikoresho binini bya dv / dt mubisanzwe bihuje nivanga kumuriro no hasi kugeza muburyo bwo guha ubushobozi. Nibyiza guhuza imirongo ya tube kuri tube kuruhande rwikigo. Gukoresha ibicuruzwa byo hejuru bihindura kandi bizagabanya ubushobozi bwo guhugura, bityo bikagabanya guhuza.

18. Nibyiza kudakoresha vias kubintu bikunze kwivanga, nkuko bizabangamira ibice byose ko the Binyuze muri.

. Irashobora gusuzumwa muburyo nyabwo.

20. Kurinda kwivanga bisanzwe, koresha ingingo hamwe nimbaraga ziva muburyo bumwe.

. Uburyo bwo guhuza ubutaka bwerekanwe mugishushanyo gikurikira:

22. Iyo bihuriweho, banza bacire urubanza imiterere mbere yo guhuza. Ubutaka bwo gutoranya no kwibeshya bukwiye guhuzwa ninkingi mbi yumuharuro wo gusohoka, hamwe nibimenyetso byimpimbano bigomba gukurwa mubipolisi byiza byo gusohoka. Ubutaka buto bwo kugenzura no gutwara busanzwe bukwiye guhuzwa na e / s pole cyangwa kumenyekanisha icyitegererezo cyo kuzimya umuyoboro uhuza kugirango wirinde kwivanga. Mubisanzwe kugenzura no gutwara ibice bya IC ntabwo biyobowe ukundi. Muri iki gihe, impongano yo kuyobora kuva kumurwanya ugana hejuru kugeza hejuru yubutaka bugomba kuba gito bishoboka kugirango ugabanye kwivanga neza no kunoza ukuri kwimpimbano.

23. Ibisohoka voltage Umuyoboro wa Sample nibyiza kuba hafi yikosa amplifier aho kuba ibisohoka. Ibi ni ukubera ko ibimenyetso byo hasi bitari byoroshye kwivanga kuruta ibimenyetso byigezweho. Ibimenyetso bya Sampling bigomba kuba hafi bishoboka kugirango bigabanye urusaku.

24. Witondere imiterere ya serwati kuba kure kandi perpendicular kuri mugenzi wawe kugirango igabanye inductance, cyane cyane Indumisi yo kubika ingufu hamwe na Indumu.

25. Witondere imiterere iyo ubushobozi bwinshi-butanga cyane hamwe nubushobozi bwo hasi-bukoreshwa muburyo busa, ubushobozi bwisumbuye bugera kuri uyikoresha.

26. Kwivanga-kugabanya ubusanzwe muburyo butandukanye (munsi ya 1m), hamwe no kwivanga cyane ni uburyo rusange, mubisanzwe hamwe nimirase.

27. Niba ikimenyetso kinini cyo gukuramo kijyanye nigipimo cyinjiza, biroroshye gushiraho EMI (uburyo busanzwe). Urashobora gushira impeta ya rugnetic kumurongo winjiza hafi yimbaraga. Niba EMI yagabanijwe, yerekana iki kibazo. Igisubizo cyiki kibazo nugugabanya guhuza cyangwa kugabanya emi yumuzunguruko. Niba urusaku rwinshi rutari rwuzuyemo isuku kandi rukorerwa ibyinjijwe, EMI (uburyo butandukanye) nabwo bizashingwa. Muri iki gihe, impeta ya magneti ntabwo ishobora gukemura ikibazo. Ikurikiranya ibirindiro bibiri-byinshi-byinshi (symmetrical) aho ibyinjijwe ari hafi yimbaraga. Kugabanuka byerekana ko iki kibazo kibaho. Igisubizo cyiki kibazo ni ukunoza gushungura, cyangwa kugabanya ibisekuru byurusaku rwinshi-bwinshi ukoresheje buffer, guhindagurika nubundi buryo.

28. Gupima uburyo butandukanye hamwe nuburyo busanzwe bugezweho:

29. Akayunguruzo ka EMI kagomba kuba hafi yumurongo winjira bishoboka, kandi insinga yumurongo winjira igomba kuba ngufi ishoboka kugirango igabanye ubutegetsi hagati yimbere ninyuma ya emi. Incuranga yinjira irangiye cyane hamwe nubutaka bwa chassis (uburyo buke bwasobanuwe haruguru). Ibisohoka EMI Akayunguruzo kagomba gufatwa kimwe. Gerageza kongera intera hagati yumurongo winjira hamwe na dv / dt ibimenyetso byinshi, hanyuma ubitekereze muburyo.
