Niki EMI Yivanga na Electromagnetic
Amavu n'amavuko
Kwivanga kwa Electromagnetic (EMI) bisobanuwe muri rusange nkumuriro uwo ariwo wose w'amashanyarazi cyangwa magnetiki utesha agaciro cyangwa ubangamira ubunyangamugayo bwibimenyetso cyangwa ibice nibikorwa by ibikoresho bya elegitoroniki.Kwivanga kwa electronique, harimo na radiyo yumurongo wa interineti, mubisanzwe biri mubice bibiri bigari.Imyuka ihumanya imyanda isanzwe ikorwa n'abantu kandi igarukira mu gace gato ka radiyo.Hum kuva kumurongo w'amashanyarazi ni urugero rwiza rwo kwangiza imyanda.Birakomeza cyangwa rimwe na rimwe.Imirasire yagutse irashobora gukorwa n'abantu cyangwa karemano.Bakunda kwibasira uturere twagutse twa electronique.Nibintu bye bimwe byabaye bidasanzwe, rimwe na rimwe, cyangwa bikomeza.Ibintu byose kuva inkuba ikubita kuri mudasobwa bitanga imirasire yagutse.
Inkomoko ya EMI
Imikoreshereze ya electromagnetiki EMI muyunguruzi ikora irashobora kuza muburyo butandukanye.Imbere y'ibikoresho by'amashanyarazi, kwivanga birashobora kubaho kubera impedance, imiyoboro ihindagurika muguhuza insinga.Irashobora kandi guterwa nimpinduka za voltage mubayobora.EMI ikorwa hanze ningufu zo mu kirere nkumuriro wizuba, amashanyarazi cyangwa imirongo ya terefone, ibikoresho, numurongo wamashanyarazi.Hafi ya EMI ikorerwa kumurongo w'amashanyarazi kandi ikoherezwa mubikoresho.EMI muyunguruzi ni ibikoresho cyangwa module y'imbere yagenewe kugabanya cyangwa gukuraho ubu bwoko bwo kwivanga.
EMI muyunguruzi
Utarinze gucengera mubumenyi bukomeye, kwivanga kwinshi kwa electromagnetic ni murwego rwo hejuru.Ibi bivuze ko mugihe upimye ikimenyetso nka sine wave, ibihe bizaba byegeranye cyane.Akayunguruzo ka EMI gafite ibice bibiri, capacitor na inductor, ikorana kugirango ihagarike ibyo bimenyetso.Imiyoboro ihagarika imiyoboro itaziguye kandi ikanyura muyindi nzira inyuramo amashanyarazi menshi yinjizwa mubikoresho.Inductor ni ikintu gito cyane cya electromagnet igumana ingufu mumashanyarazi mugihe amashanyarazi anyuze muri yo, bikagabanya ingufu rusange.Imiyoboro ikoreshwa muri EMI muyunguruzi, yitwa shunt capacitor, igumane imiyoboro yumurongo mwinshi murwego runaka kure yumuzingi cyangwa ibice.Shunt capacitor igaburira inshuro nyinshi / kwivanga kuri inductor yashyizwe murukurikirane.Mugihe ikinyura muri buri inductor, imbaraga rusange cyangwa voltage iratemba.Byiza, inductors zigabanya kwivanga kuri zeru.Ibi byitwa kandi bigufi hasi.EMI muyunguruzi ikoreshwa muburyo butandukanye bwa porogaramu.Baboneka mubikoresho bya laboratoire, ibikoresho bya radio, mudasobwa, ibikoresho byubuvuzi, nibikoresho bya gisirikare.
Wige kubyerekeye EMI / EMC yo gushungura ibisubizo

Imiyoboro ihagarika imiyoboro itaziguye kandi ikanyura muyindi nzira inyuramo amashanyarazi menshi yinjizwa mubikoresho.Inductor ni igikoresho gito cya electromagnetic igikoresho kigumana ingufu mumashanyarazi mugihe amashanyarazi anyuze muri yo, bigatuma voltage igabanuka muri rusange.Imiyoboro ikoreshwa muri EMI muyunguruzi, yitwa shunt capacitor, igumane imiyoboro yumurongo mwinshi murwego runaka kure yumuzingi cyangwa ibice.Shunt capacitor igaburira inshuro nyinshi / kwivanga kuri inductor yashyizwe murukurikirane.Mugihe ikinyura muri buri inductor, imbaraga rusange cyangwa voltage iratemba.Byiza, inductors zigabanya kwivanga kuri zeru.Ibi byitwa kandi bigufi hasi.EMI muyunguruzi ikoreshwa muburyo butandukanye bwa porogaramu.
