Pili i ka ʻume mākenēki flux density, ʻoi aku ka kiʻekiʻe o ferrosilicon ma mua o ka sendust. Eia nō naʻe, ʻoi aku ka nui o nā pōmaikaʻi ʻoi loa o ka sendust, i hōʻike ʻia i ka saturation palupalu ʻoi aku, ka pohō kumu nui ʻole, ka paʻa o ka mahana a me ke kumu kūʻai haʻahaʻa o ka hoʻohana. Hiki i nā Inductors e hoʻohana ana i nā ʻenekini paukū pauka sendust ke hoʻopau i nā mea maikaʻi ʻole i hoʻokumu ʻia e ka ea o ke kani uila magnet.

nā kikoʻī e like me kēia:

1. ʻOi aku ka liʻiliʻi o ka nui o ka flux density B o ka ferrite ma mua a i ʻole ka 0.5T, ʻo ia ka mea i ʻoi aku i ka hapalua o ka letust. ʻO ia e ʻōlelo, ma lalo o ka leo like, ʻoi aku ka haʻahaʻa o ka mālama ikehu o ferrite ma mua o ka sendust.

2. ʻOi aku ka haʻahaʻa o ke ana wela o ka ferrite i ka sendust. Hoʻoemi nui ʻia ka nui o ka magnetic saturation magnet o ka ferrite ma lalo o nā kūlana wela kiʻekiʻe, ʻoiai ʻaʻole e loli ka nui o ka magnetic saturation

3. Loaʻa nā ʻano o Ferrite o ka wikiwiki a me ka piha. Inā ʻoi aku ia i ka waiwai o kēia wā palekana, hiki iā ia ke hoʻohiolo i ka hana inductance ma ke ʻano holoʻokoʻa, ʻoiai ʻo Sendust nā ʻano o ka palupalu a me ka piha a hiki ke kū i nā helu o kēia wā.

4. Kūpono loa nā ʻāpana Sendust no nā inductors kānana mālama mālama ikehu i ka hoʻololi ʻana i nā lako mana. Hoʻohālikelike ʻia me nā ferrite āpau ea a i ʻole nā ​​ʻāpana pauka hao o ka nui like a me ka permeability, hiki i nā ʻāpana sentust me ka saturation flux kiʻekiʻe ke hāʻawi i ka ikehu mālama kiʻekiʻe.

5. Ke pono e hele i kahi uila kamaʻilio nui me ka ʻole o ka hoʻoulu ʻana i nā inductors kānana walaʻau piha, hiki i ka hoʻohana ʻana i ka core sendust ke hōʻemi i ka nui o ka kānana pūnaewele. Ma muli o ka helu o nā huli i koi ʻia ma mua o ka ferrite, loaʻa pū kahi coefficient magnetostriction kokoke i ka ʻole, ʻo ia hoʻi, he mālie loa ia i ka hana o ka walaʻau a i ʻole ka pūnaewele i ka pae pinepine e lohe ʻia.

6. ʻO ke kiʻekiʻena flux density a me nā ʻano pohō kumu haʻahaʻa e kūpono i nā kikowaena sendust kūpono loa no ka mana o ka hoʻopili ʻana i ka mana a me nā noi hoʻokele unidirectional, e like me nā transformer flyback a me nā transformer pulse.
