Uma kuqhathaniswa ne-magnetic saturation flux density, i-ferrosilicon iphakeme kune-sendust. Kodwa-ke, i-sendust inezinzuzo ezivelele kakhulu, ezibonakala ngokugcwala okungcono okuthambile, ukulahlekelwa okuyisisekelo okunganakwa, ukuzinza kwezinga lokushisa kanye nezindleko eziphansi zokusetshenziswa. Ama-inductors asebenzisa ama-sendust magnetic powder cores angaqeda izici ezingathandeki ezibangelwa igebe lomoya lendandatho kazibuthe ye-ferrite.

imininingwane kanje:

1. Ukuminyana kukazibuthe okuguquguqukayo B kwe-ferrite kungaphansi noma kulingana no-0.5T, okungaphansi kwengxenye yaleyo ye-sendust. Okusho ukuthi, ngaphansi kwevolumu efanayo, isitoreji samandla se-ferrite siphansi kakhulu kune-sendust.

2. Ukumelana nezinga lokushisa kwe-ferrite kuphansi kakhulu kune-sendust. I-magnetic saturation flux density ye-ferrite incipha kakhulu ngaphansi kwezimo zokushisa eziphezulu, kuyilapho ukugcwala kukazibuthe ku-flux density ye-sendust ayishintshi kakhulu ngaphansi kwezimo zokushisa eziphezulu.

3. I-Ferrite inezici zokusheshisa nokugcwala. Uma idlula inani lamanje eliphephile, ingabangela umsebenzi we-inductance ukuthi ugoqe usuwonke, kuyilapho i-Sendust inezici zokuthamba nokugcwala futhi ingamelana namanani aphezulu amanje.

4. Ama-Sendust cores afaneleka kakhulu kuma-inductors okuhlunga okugcina amandla ekushintsheni amandla kagesi. Uma kuqhathaniswa ne-air-gap ferrite noma i-iron powder cores enobukhulu obufanayo kanye nokufinyeleleka, ama-sendust cores ane-flux saturation ephezulu anganikeza amandla okugcina aphezulu.

5. Uma kudingekile ukudlula i-voltage enkulu yokuxhumana ngaphandle kokukhiqiza ama-inductors okuhlunga umsindo ogcwele, ukusetshenziswa kwe-sendust core kunganciphisa ubukhulu besihlungi se-intanethi. Ngenxa yokuthi inani lokujika elidingekayo lincane kunele-ferrite, i-sendust nayo ine-coefficient ye-magnetostriction esondele ku-zero, okungukuthi, ithule kakhulu ekusebenzeni komsindo noma okwamanje ku-inthanethi ebangeni lefrikhwensi ezwakalayo.

6.Ukuminyana okuguquguqukayo okuphakeme kazibuthe kanye nezici zokulahlekelwa okuyisisekelo eziphansi zenza ama-sendust cores afaneleke kakhulu kumasekhethi okulinganisa isici samandla kanye nezicelo zedrayivu ye-unidirectional, njengama-flyback transformers nama-pulse transformers.
