Inductor na gama gariyana nufin cewa an raunata coils guda biyu akan tushen ƙarfe ɗaya, tare da karkatar da iska, adadin juyi da lokaci ɗaya. Yawanci ana amfani da shi wajen sauya kayan wuta don tace siginonin tsoma baki na yanayin gama gari, ana amfani da matattarar EMI don murkushe raƙuman wutar lantarki da aka samar ta layin sigina mai sauri daga haskakawa waje. Inductance na yau da kullun a shigar da tsarin wutar lantarki yawanci shine don rage radiation da hayaniyar yanayin mitar na yau da kullun. Duk da haka, babban inductance na gama-gari yana da tasiri mai kyau na dakatarwa a kan ƙananan rikice-rikice, kuma yawan mita na iya zama mafi muni, amma ƙananan jin dadi yana da mummunan tasiri akan ƙananan damuwa.

Yana da tasirin dannewa a fili akan hayaniyar yanayin gama gari. Ka'idar aiki ita ce lokacin da yanayin gama gari na yanzu ya ratsa cikin ɓangaren, inductances na inductor biyu suna haɗuwa. Amma don hayaniyar yanayi daban-daban, inductances guda biyu suna daidai da ɗaukar bambanci, ƙimar inductance ta ragu, kuma tasirin suppression zai raunana.

Girman inductance na gama gari zai shafi aikin EMC kai tsaye. Babban aikin shine ware siginar yanayin gama gari da rage tsangwama na yanayin gama gari na waje, don haka rage tasirin wutar lantarki. Hakanan zai iya rage siginar yanayin gama gari na ciki kuma ya rage tasiri akan grid ɗin wuta. Duk da haka, babban inductance na gama-gari yana da tasiri mai kyau na dakatarwa a kan ƙananan rikice-rikice, kuma yawan mita na iya zama mafi muni, amma ƙananan jin dadi yana da mummunan tasiri akan ƙananan damuwa.

Abin da muke yawan amfani da shi a ƙarshen shigar da wutar lantarki shine ƙarfin x, ƙarfin y da inductance na gama gari. Ƙarfin yana da ƙananan ƙin siginar, wanda ke aiki azaman kewayawa da siginar haɗawa. Inductance yana da babban tasiri ga siginar kuma yana taka rawa wajen nunawa da ɗaukar siginar tsangwama mai tsayi.

Tsangwamar da ke tsakanin layukan wutar lantarki zuwa ƙasa ana kiranta katsalandan yanayin gama gari, kuma tsangwamar da ke tsakanin layukan wutar lantarkin ana kiranta katsalandan yanayin yanayi daban-daban. Lokacin da aka haɗa inductance da capacitance a cikin tacewa, tasirin tacewa ya fi kyau, kuma mitar band inda inductance da capacitance ke taka rawa. Haka kuma daban. Y capacitor da Y capacitor suna taka rawa wajen tace tsangwama na gama gari, kuma X capacitor galibi yana aiki azaman siginar gajeriyar kewayawa, yana rage hanyar da siginar banbanta ke gudana, ta haka yana rage oscillation da parasitic sigogi ke haifarwa. da kewaye da haifar da high-mita watsi.

Lokacin da aka cire inductance ko capacitance a cikin zane, ragowar ɓangaren zai ci gaba da aiki, amma sakamakon zai zama mafi muni. Gabaɗaya magana, mafi girman girman yanayin yanayin gama gari, mafi kyau. Lokacin zabar inductor na yau da kullun, zaɓin ya dogara ne akan madaidaicin mitar impedance. A lokaci guda, ya kamata a ba da hankali ga tasirin tasirin yanayin bambance-bambance akan siginar.
