Qhov sib txawv ntawm hom sib xws inductance thiab plawg hom hom inductance | TAU TXAIS

Qhov txawv ntawm hom thiab txawv hom hom inductance yog dab tsi? Gvey kev tsim kom muaj kev lag luam inductor hais luv luv.

Cov hom ntoo txhawm chim, tseem hu ua Hom hom Txheeb Txheeb, feem ntau siv los lim cov nquag siv hom EMI teeb liab hauv kev hloov cov khoom siv hluav taws xob ntawm computers.In board daim npav tsim, hom hom inductor kuj ua lub luag haujlwm ntawm EMI lim, uas yog siv los txhawm rau hluav taws xob hluav taws xob tso tawm los ntawm kab hluav taws xob loj cov kab.

Kev sib txawv ntawm hom inductance yog ib hom inductance uas tuaj yeem tiv taus qhov loj siab cuam tshuam ntawm hom txawv, kuj hu ua hom sib txawv choke coil.Yog muaj 3 yam ntawm cov ntaub ntawv tseem ceeb rau cov hom tsis txawv inductors.Qhov nqi rau ib chav ntim ntawm Fe-Si-Al sib nqus hmoov tub ntxhais yog qhov qis tshaj, yog li nws tsim nyog rau kev ua cov qauv sib txawv ntawm cov inductors.Qhov nqe ntawm Fe-Ni 50 thiab Fe-Ni Mo sib nqus hmoov tseem ceeb yog ntau dua li ntawm Fe-Si Al sib nqus hmoov tub ntxhais, uas yog ntau haum rau kev siv tub rog thiab qee zaus muaj kev ntim ntau thiab ua tau zoo.

Qhov sib txawv ntawm hom sib xws inductance thiab plawg hom hom inductance

1.Cov hom hom inductance winding feem ntau yog ob zaug xaim bidirectional; Ntau hom inductors ua viav vias nyob rau hauv ib qho kev taw qhia.

2.Qhov lim inductor uas suppresses sib cuam tshuam hom sib txuam yog hu ua common-mode inductor; Lub lim inductor uas txwv tsis pub muaj kev cuam tshuam txawv hom sib txawv hu ua plawg hom inductor.

3.Qhov hom kev sib koom ua ke ntawm ob pab pawg ntawm coils nrog tib tus coils, tib lub xov hlau ntawm cov xaim thiab qhov ntsuas sib txawv hauv tib qho qub yog qhov sib txawv;

4.Cov hom teeb liab: ob tus naj npawb tshiab tsim tawm rau ntawm xoom kab thiab hluav taws kab feem; Cov hom teeb liab sib txawv: tsim rau siv nyob rau hauv tib lub teeb liab.

5.Cov khoom siv hom sib xyaw ua ke: vim tias ob pawg ntawm coils ntawm tib tus tub ntxhais raug mob rau hauv cov lus qhia rov qab, yog li ntawd tus tub ntxhais tsis ntshai ntawm kev saturation.High conductance ferrite cov khoom siv yog cov khoom siv dav dav hlau nplaum loj hauv khw.

Saum toj no yog hom hom txhawm chim thiab txawv hom hom inductance qhov sib txawv, vam tias yuav pab tau koj.Peb yog ib tus kws tshaj lij kev lag luam hauv Suav teb, txais tos tham!
