Hom hom inductance lim circuit, La thiab Lb yog hom hom inductance coils. Nyob rau hauv txoj kev no, thaum lub cev tam sim no nyob rau hauv Circuit Court dhau los ntawm cov hom inductance, qhov rov qab magnetic teb generated los ntawm cov tam sim no nyob rau hauv inductance coils raug mob nyob rau hauv tib theem tshem tawm ib leeg. Nyob rau hauv cov ntaub ntawv no, ib txwm teeb liab tam sim no feem ntau cuam tshuam los ntawm coil kuj. Thaum cov hom tam sim no Thaum dhau los ntawm lub kauj, vim yog isotropy ntawm hom hom tam sim no, ib qho chaw sib nqus nyob rau hauv tib qho kev taw qhia yog tsim nyob rau hauv lub kauj, uas ua rau kom lub induction ntawm lub kauj, thiab ua rau lub kauj tshwm li siab impedance. thiab ua rau muaj zog damping nyhuv. Nws feem ntau yog siv los lim cov kab hluav taws xob sib txawv hauv cov khoom siv hluav taws xob hloov pauv. EMI filtering yog siv los tua cov hluav taws xob hluav taws xob uas tsim los ntawm cov kab hluav taws xob ceev ceev los ntawm kev tawm sab nraud.

Hom hom inductance lim circuit, La thiab Lb yog hom hom inductance coils. Ob lub coils raug mob ntawm tib lub tub ntxhais hlau nrog tib lub teeb thiab theem. Nyob rau hauv txoj kev no, thaum lub cev tam sim no nyob rau hauv Circuit Court dhau los ntawm cov hom inductance, qhov rov qab magnetic teb generated los ntawm cov tam sim no nyob rau hauv inductance coils raug mob nyob rau hauv tib theem tshem tawm ib leeg. Nyob rau hauv cov ntaub ntawv no, ib txwm teeb liab tam sim no feem ntau cuam tshuam los ntawm lub coil kuj. Thaum lub hom phiaj tam sim no Thaum dhau los ntawm lub kauj, vim yog isotropy ntawm cov hom tam sim no, ib qho chaw sib nqus nyob rau hauv tib txoj kev yog generated nyob rau hauv lub kauj, uas ua rau kom lub induction ntawm lub kauj, ua rau lub kauj zoo li impedance siab, thiab ua rau muaj zog damping nyhuv.
Qhov tseeb, thaum ib kawg ntawm lub lim dej txuas nrog rau qhov cuam tshuam, thiab lwm qhov kawg yog txuas nrog cov khoom cuam tshuam, La thiab C1, Lb thiab C2 tsim ob pawg ntawm cov lim dej qis, uas tuaj yeem tswj cov kab ntau. hom EMI teeb liab mus rau theem qis. Qhov Circuit Court no tuaj yeem tsis tsuas yog cuam tshuam cov xaim hluav taws xob sab nraud EMI, tab sis kuj tseem txo qis EMI cov cim qhia los ntawm kab nws tus kheej, uas tuaj yeem txo qhov kev siv ntawm EMI cuam tshuam. Ib qho khoom siv hauv tsev tsim me me hom inductor, siv cov suab nrov nrov tiv thaiv kev tiv thaiv, hom hom choke coil qauv, tsis muaj teeb liab attenuation, me me, yooj yim siv, zoo tshuav, siv tau yooj yim, zoo thiab lwm yam zoo. Nws yog dav siv nyob rau hauv ob-balanced tuning li, multi-frequency transformers, impedance transformers, balanced thiab unbalanced transformers, thiab lwm yam.
Hom hom inductor txhais tau hais tias ob lub coils raug mob ntawm tib lub tub ntxhais hlau, cov windings yog qhov sib txawv, tus naj npawb ntawm cov lem thiab theem yog tib yam. Nws feem ntau yog siv los lim cov kab hluav taws xob sib txawv hauv cov khoom siv hluav taws xob hloov pauv. EMI filtering yog siv los tua cov hluav taws xob hluav taws xob uas tsim los ntawm cov kab hluav taws xob ceev ceev los ntawm kev tawm sab nraud.
