Sib nqus nplhaib inductors tau muab faib ua ob pawg: hom hom inductors thiab txawv hom inductors. Hom hom inductors tau qhia nyob rau hauv tsab xov xwm dhau los. Daim ntawv no qhia txog magnetic nplhaib sib txawv hom inductors.
Differential hom inductors feem ntau yog siv los lim tawm qhov sib txawv hom cuam tshuam. Differential hom kev cuam tshuam yog ib hom kev cuam tshuam hauv qhov sib txawv ntawm cov teeb liab sib kis, uas feem ntau tshwm ntawm ob lub xov hlau. Hom kev cuam tshuam no feem ntau yog tshwm sim los ntawm qhov tsis sib xws ntawm qhov ntev, qhov dav thiab qhov sib txawv ntawm ob kab teeb liab sib txawv ntawm lub rooj tsav xwm Circuit Court.
Txawv hom inductors feem ntau yog ua ke nrog cov capacitors los tsim LC cov ntxaij lim dej kom txo cov suab nrov. Hauv EMC ib feem ntawm kev hloov hluav taws xob, qhov sib txawv hom inductors feem ntau yog siv los txwv cov suab nrov los ntawm kev hloov hluav taws xob rau hauv daim phiaj hluav taws xob. Nyob rau hauv ib txwm muaj xwm txheej, qhov sib txawv hom inductor tsuas muaj ib qho winding, thiab cov ntaub ntawv tseem ceeb tshaj plaws yog hlau hmoov core, alloy hmoov core, nickel zinc thiab lwm yam. Cov tub ntxhais hlau yog ua los ntawm high purity hlau hmoov cov khoom uas muaj me me heev thiab rwb thaiv tsev ntawm ib leeg, thiab muaj ib tug uniform faib huab cua sib txawv. Thawj zaug tsocai ntawm cov hmoov hlau yog nruab nrab ntawm 10 thiab 75, cov khoom siv hlau tsis loj, feem ntau hauv qab 100kHz, tab sis cov khoom siv yog tsawg.
Cov khoom siv hlau hmoov hlau yog -2 (liab / pob tshab), -8 (daj / liab), -18 (ntsuab / liab), -26 (daj / dawb) , -28 (grey/green), -33 (grey/daj), -38 (grey/dub), -40 (ntsuab/daj), -45 (dub), -52 (ntsuab/xiav), thiab lwm yam. Tam sim no, feem ntau siv yog -26 daj dawb nplhaib. Alloy core yog feem ntau siv hlau silicon aluminium (Sendust), hlau npib tsib xee molybdenum (MPP), hlau nickel (highflux), permeability ntawm 14 ~ 500, feem ntau siv yog hlau silicon txhuas, nqi-zoo, yog tam sim no feem ntau. dav siv nyob rau hauv pej xeem cov khoom.
Nickel-zinc magnetic nplhaib, qhov permeability feem ntau yog tsawg dua 1500. Cov khoom muaj qhov kub tsis tshua muaj coefficient ntawm cov nplhaib sib nqus, siab Curie kub thiab cov yam ntxwv zoo siab, thiab feem ntau yog siv hauv nruab nrab thiab siab zaus circuits. Ob txoj kev sib nqus sib nqus flux cov lus qhia ntawm hom hom inductor yog qhov sib txawv, yog li ob hom sib nqus flux tuaj yeem tshem tawm ib leeg thiab yuav tsis muaj qhov tshwm sim saturation. Qhov sib txawv hom inductor yog qhov sib txawv, tsuas yog ib qho winding xwb, nws yuav tsum tau tsom mus rau seb puas yuav muaj qhov saturation tom qab tam sim no. Feem ntau, cov tuam txhab lag luam tseem tsom rau kev ntsuas thiab ntsuas qhov saturation tam sim no (tseem hu ua superposition tam sim no) ntawm qhov sib txawv hom inductors. Nws yog tsim nyog hais tias ntxiv rau kev siv lub nplhaib sib nqus inductors ua qhov sib txawv hom inductors, I-inductors kuj tau siv ntau hom inductors thiab tau siv dav hauv circuits.
