Ngokunxulumene noxinzelelo lwemagnethi lokugcwala, i-ferrosilicon iphezulu kune-sendust. Nangona kunjalo, i-sendust ineenzuzo ezivelele ngakumbi, ezibonakaliswa kwi-saturation ethambileyo engcono, ilahleko engundoqo engabalulekanga, ukuzinza kweqondo lokushisa kunye neendleko eziphantsi zokusetyenziswa. I-inductors esebenzisa i-sendust magnetic powder cores inokuphelisa izinto ezingathandekiyo ezibangelwa i-gap yomoya we-ring magnetic ye-ferrite.

iinkcukacha ngolu hlobo lulandelayo:

1. Uxinaniso lwemagnethi lombane lwe-ferrite lungaphantsi okanye lulingana no-0.5T, olungaphantsi kwesiqingatha se-sendust. Oko kukuthi, phantsi komthamo ofanayo, ukugcinwa kwamandla e-ferrite kuphantsi kakhulu kunokuthumela.

2. Ukumelana nokushisa kwe-ferrite kuphantsi kakhulu kwi-sendust. Uxinzelelo lwemagnethi oluguquguqukayo lwemagnethi luncitshiswe kakhulu phantsi kweemeko zobushushu obuphezulu, ngelixa ukugcwala kwemagneti ukuxinana kwemagnethi akutshintshi kakhulu phantsi kweemeko zobushushu obuphezulu.

3. I-Ferrite ineempawu zokukhawuleza kunye nokuzala. Ukuba idlula ixabiso langoku elikhuselekileyo, linokubangela ukuba umsebenzi we-inductance uwele ngokupheleleyo, ngelixa i-Sendust ineempawu zokuthambisa kunye nokugcwala kwaye inokumelana namaxabiso aphezulu angoku.

4. Ii-cores ze-Sendust zifanelekile kakhulu kwii-inductors zokucoca ukugcinwa kwamandla ekutshintsheni amandla ombane. Xa kuthelekiswa ne-air-gap ferrite okanye i-iron powder cores yobukhulu obufanayo kunye nokunyamezela, i-sendust cores ene-high flux saturation inokubonelela ngamandla okugcina aphezulu.

5. Xa kuyimfuneko ukudlula i-voltage enkulu yonxibelelwano ngaphandle kokuvelisa i-inductors yokucoca ingxolo epheleleyo, ukusetyenziswa kwe-sendust core kunokunciphisa ubungakanani befayile ye-intanethi. Ngenxa yokuba inani lokujika elifunekayo lingaphantsi kwelo le-ferrite, i-sendust nayo ine-coefficient yemagnetostriction ekufutshane no-zero, oko kukuthi, izolile kakhulu ekusebenzeni kwengxolo okanye yangoku kwi-intanethi kuluhlu lwamaza omsindo oluvakalayo.

I-6.Ubuninzi be-magnetic flux density kunye ne-low core loss loss features zenza ukuba i-sendust cores ifaneleke kakhulu kwiisekethe zokulinganisa izinto zamandla kunye nezicelo ze-unidirectional drive, ezifana ne-flyback transformers kunye ne-pulse transformers.
