Imodi evamile iyaminyanisaivamise ukusetshenziswa ekushintsheni amandla ekhompiyutha ukuhlunga amasiginali wokuphazamiseka kagesi wemodi evamile.
Ii-inductor yemodi evamileiyisihlungi esinezinhlangothi ezimbili. Ngakolunye uhlangothi, kuyadingekaisihlungiikhiphe ukuphazamiseka kukazibuthe wemodi evamile emugqeni wesignali, futhi ngakolunye uhlangothi, idinga ukucindezela ukuthikamezeka kazibuthe kagesi okukhishwa iyodwa, ukuze ingaphazamisi indawo evamile yokusebenza kazibuthe kagesi yezinye izinto zokusebenza zikagesi endaweni efanayo.
Ekuklanyweni kwebhodi lesifunda, ii-inductor yemodi evamilefuthi isebenza njenge-Isihlungi se-EMIukucindezela amaza kagesi asakazwa imigqa yesignali yesivinini esikhulu.
Ii-inductor yemodi evamileizokwenziwa ngokuhambisana nalezi zidingo ezilandelayo.
(1)Izintambo ezilimele kunkambo yekhoyili kufanele zivaleleke ukusuka kwenye ukuze kuqinisekiswe ukuthi akukho ukuphuka kanye nokujikeleza okufushane phakathi kwamakhoyili ngaphansi kwesenzo se-over-voltage yesikhashana;
(2)Lapho ikhoyili igeleza kugesi omkhulu osheshayo, ingqikithi kazibuthe ngeke igcwale.
(3)Ingqikithi kazibuthe kukhoyili izovalwa ikhoyili ukuze kuvinjwe ukuphuka ngaphansi kokuguquguquka kwesikhashana
(4)Ikhoyili izofakwa ungqimba olulodwa ngangokunokwenzeka ukuze kwehliswe amandla e-parasitic ekhoyili futhi kuthuthukiswe amandla okuthwala ikhoyili ukuya ku-voltage engaphezu kwesikhashana.
Yiziphi izidingoama-inductors emodi evamile? Ngokuvamile, qaphela ukukhetha ibhendi yefrikhwensi edingekayo, futhi uma i-impedance yemodi evamile ikhudlwana, iba ngcono. Ngakho-ke, lapho ukhetha i-inductor yemodi evamile, udinga ukuhlola imininingwane yedivayisi, ikakhulukazi ngokuya ngejika lemvamisa ye-impedance.
