iindaba

Imilo yesetyhula kunye nentambo yokudibanisa yenza i-inductor (intambo ejikeleze i-ring magnetic isetyenziswa njenge-coil inductance), ehlala isetyenziswa kwizinto ezichasene nokuphazamiseka kweesekethe ze-elektroniki kwaye inefuthe elihle lokukhusela kwingxolo ephezulu-frequency, ngoko ke. kubizwa ngokuba lubhedu olufunxayo, kuba intsimbi isoloko isetyenziswa ngezinto zeFerrite, masithethe ngamaso e-ferrite (emva koku kubhekiselwa kuwo njengamaso angqukuva). Umphezulu womzobo yindandatho yamagnetic ehlanganisiweyo, kwaye ezantsi yindandatho yamagnetic eneziqeshana zokukhwela. Iringi kazibuthe ineempawu ezahlukeneyo ze-impedance kumaza ahlukeneyo. Ngokubanzi, i-impedance incinci kakhulu kumaza aphantsi. Xa i-frequency yesignali iphakama, i-impedance ye-ring magnetic inyuka ngokukhawuleza. Ukusebenza kwe-inductance kwaziwa kakuhle. Ukuphakama komthamo wesignali, kokukhona kulula ukusasazeka. Ngokubanzi, akukho maleko ekhuselayo kwisekethe, kwaye i-antenna enophawu oluhle inokufumana imiqondiso eyahlukeneyo ye-clutter high-frequency evela kwindawo engqongileyo. Ukutshintsha ukuhanjiswa kweempawu eziluncedo kwaye kwaphazamiseka kakhulu ekusebenzeni okuqhelekileyo kwezixhobo zombane, ngoko ke uphazamiseko lwe-electromagnetic (EM) lwezixhobo zombane kufuneka luncitshiswe. Ngaphantsi kwesenzo sendandatho yamagnetic, nokuba isignali eqhelekileyo eluncedo idlula kakuhle, isignali yokuphazamiseka kwe-high-frequency interference inganyanzeliswa kakuhle, kwaye ixabiso liphantsi. Umbala weringi inductance

I-Inductance ikwadlala indima ebalulekileyo ekukhuseleni umqondiso, ukuhluza ingxolo, ukuzinza kwangoku kunye nokunyanzeliswa kwe-electromagnetic interference.

1. Ukuhlelwa kwe-inductance:

Ihlelwa ngokusebenza rhoqo

I-inductors inokwahlulwa ibe yi-inductors ephezulu-frequency, i-intermediate-frequency inductors kunye ne-low-frequency inductors ngokwe-frequency yabo yokusebenza.

I-Air-core, i-magnetic-core kunye ne-copper-core inductors ziqhelekile ziphakathi-frequency okanye high-frequency inductors, ngelixa ii-iron-core inductors ubukhulu becala zizii-inductors ezisezantsi-frequency.
