Imo yesiqhelo inductance filter circuit, i-La kunye ne-Lb ziikhoyili ze-inductance zemo yesiqhelo. Ngale ndlela, xa umsinga oqhelekileyo kwisiphaluka udlula kwi-inductance yemowudi eqhelekileyo, i-reverse magnetic fields eyenziwa yimisinga kwi-coil inductance inxeba kwisigaba esifanayo sokurhoxisa enye kwenye. Kule meko, isignali eqhelekileyo yangoku ichaphazeleka kakhulu kukuchasana kwekhoyili. Xa imowudi eqhelekileyo yangoku Xa udlula kwikhoyili, ngenxa ye-isotropy yendlela eqhelekileyo yangoku, intsimi yamagnetic kwicala elifanayo iveliswa kwikhoyili, eyandisa ukungeniswa kwekhoyili, kwaye yenza i-coil ibonakale njenge-impedance ephezulu. kwaye ivelisa isiphumo esinamandla sokudambisa. Ihlala isetyenziselwa ukucoca imiqondiso yokuphazamiseka kwe-electromagnetic yendlela eqhelekileyo ekutshintsheni amandla. Uhluzo lwe-EMI lusetyenziselwa ukucinezela amaza ombane oveliswa yimigca yemiqondiso enesantya esiphezulu ukusuka kwimitha engaphandle.

Imo yesiqhelo inductance filter circuit, i-La kunye ne-Lb ziikhoyili ze-inductance zemo yesiqhelo. Iikhoyili ezimbini zivalwa kumbindi wentsimbi ofanayo kunye nenani elifanayo lezibane kunye nezigaba. Ngale ndlela, xa umsinga oqhelekileyo kwisiphaluka udlula kwi-inductance yemowudi eqhelekileyo, i-reverse magnetic fields eyenziwa yimisinga kwi-coil inductance inxeba kwisigaba esifanayo sokurhoxisa enye kwenye. Kule meko, isignali eqhelekileyo yangoku ichaphazeleka kakhulu kukuchasana kwekhoyili. Xa imowudi eqhelekileyo yangoku Xa udlula kwikhoyili, ngenxa ye-isotropy yendlela eqhelekileyo yangoku, intsimi yamagnetic kwicala elifanayo iveliswa kwikhoyili, eyandisa ukungeniswa kwekhoyili, yenza i-coil ibonakale i-impedance ephezulu, kwaye ivelisa isiphumo esinamandla sokudambisa.
Enyanisweni, xa esinye isiphelo sesiphaluka sokucoca sidityaniswe kumthombo wokuphazamiseka, kwaye esinye isiphelo siqhagamshelwe kwisixhobo sokuphazamiseka, i-La kunye ne-C1, i-Lb kunye ne-C2 zenza iiseti ezimbini zeefilitha ezisezantsi, ezinokulawula umgca oqhelekileyo. Imowudi ye-EMI isignali ukuya kwinqanaba eliphantsi. Esi sekethe asikwazi ukucinezela kuphela ukungena kweempawu ze-EMI zangaphandle, kodwa kwakhona kuthintele iimpawu ze-EMI eziveliswa ngumgca ngokwawo, onokuthi unciphise ngokufanelekileyo ukuxhatshazwa kwe-EMI. I-inductor yendlela eqhelekileyo eveliswe ekhaya, ithatha amanyathelo okunciphisa ingxolo ephezulu, imowudi eqhelekileyo yokukhahlela isakhiwo sekhoyili, akukho mqondiso wokuthomalalisa, ubungakanani obuncinci, kulula ukuyisebenzisa, ibhalansi elungileyo, kulula ukuyisebenzisa, umgangatho ophezulu kunye nezinye iingenelo. Isetyenziswa ngokubanzi kwizixhobo zokulungelelanisa eziphindwe kabini, ii-multi-frequency transformers, i-impedance transformers, i-balanced and unbalanced transformers, njl.
I-inductor yemodi eqhelekileyo ithetha ukuba iikhoyili ezimbini zinxeba kwi-core yentsimbi efanayo, i-windings ichasene, inani lokujika kunye nesigaba siyafana. Ihlala isetyenziselwa ukucoca imiqondiso yokuphazamiseka kwe-electromagnetic yendlela eqhelekileyo ekutshintsheni amandla. Uhluzo lwe-EMI lusetyenziselwa ukucinezela amaza ombane oveliswa yimigca yemiqondiso enesantya esiphezulu ukusuka kwimitha engaphandle.
