I ka pane ʻana i ke ʻano honua o ka mālama ʻana i ka ikehu akamai, pono e hoʻolālā ʻia ke kamaʻilio uila a me nā huahana kelepona lawe lima e hoʻolālā ʻia me ka hana kiʻekiʻe a me ka hoʻohana haʻahaʻa haʻahaʻa.No laila, ʻo ka mana inductor ke kuleana no ka hoʻololi ʻana i ka mālama ʻana i ka ikehu a me ka kānana hoʻoponopono ʻana i loko o ka module mana e pāʻani i kahi mea nui e mālama i ka ikehu.

I kēia manawa, ʻaʻole hiki i ka hana o nā mea magnet ferrite ke hoʻokō i ka miniaturization a me nā koi kiʻekiʻe o kēia manawa.mea hoʻokomo manahuahana.Pono ia e hoʻololi i nā ʻāpana magnetic metala me nā kaola magnetic saturation kiʻekiʻe i mea e haki ai i ka bottleneck ʻenehana o ka hanauna e hiki mai ana o nā huahana micro/kiʻekiʻe o kēia manawa a hoʻomohala i nā alapine kiʻekiʻe, miniaturized, kiʻekiʻe kiʻekiʻe kiʻekiʻe, a me nā modula mana kiʻekiʻe. .

I kēia manawa, ke ulu nui nei ka ʻenehana o nā mea hoʻohui metala, a ʻo kahi kuhikuhi hoʻomohala ʻē aʻe he kiʻekiʻe-mehana co fired layer chip based metal power inductors.Ke hoʻohālikelike ʻia i nā inductors i hoʻohui ʻia, loaʻa i kēia mau ʻano inductors nā pōmaikaʻi o ka miniaturization maʻalahi, nā waiwai saturation o kēia manawa, a me ke kumu kūʻai haʻahaʻa.Ua hoʻomaka lākou e loaʻa ka manaʻo mai ka ʻoihana a ua hoʻolilo ʻia i ka noiʻi a me ka hoʻomohala ʻana.Manaʻo ʻia i ka wā e hiki mai ana, e hoʻohana nui ʻia nā inductors metala i nā huahana kelepona ʻē aʻe, No ka hālāwai ʻana i ke ʻano o nā noi akamai a me ka mālama ʻana i ka ikehu.

Nā Kumu o ka ʻenehana Inductor Power

ʻO ke kumu hana o ka mana inductor i hoʻohana ʻia i ka module mana e mālama nui i ka uila ma ke ʻano o ka ikehu magnetic i ka mea magnetic core.Nui nā ʻano o ka noi no nā inductors, a ʻo nā ʻano o nā mea koʻikoʻi magnetic a me nā hale ʻāpana i hoʻohana ʻia i kēlā me kēia hiʻohiʻona he mau hoʻolālā like.ʻO ka maʻamau, ʻo ka ferrite magnet he kumu kiʻekiʻe Q, akā ʻo ka saturated magnetic beam he 3000 ~ 5000 gauss wale nō;Hiki i ka saturated magnetic beam o nā metala magnetic ke piʻi aku ma luna o 12000 ~ 15000 Gauss, ʻoi aku ka ʻoi aku ma mua o ʻelua o nā magnet ferrite.Wahi a ka manaʻo o ka magnetic saturation current, i hoʻohālikelike ʻia me nā magnet ferrite, e ʻoi aku ka maikaʻi o nā metala koʻikoʻi i ka miniaturization huahana a me ka hoʻolālā kiʻekiʻe o kēia manawa.

Ke hele nei ka mana i loko o ka modula mana, ʻo ka hoʻololi wikiwiki ʻana o nā transistors e hopena i ka transient a i ʻole ka hoʻouka ʻana o ka peak peak i kēia manawa e hoʻololi i ka mana inductor, e ʻoi aku ka paʻakikī a paʻakikī i ka hoʻoponopono ʻana i nā ʻano o ka inductor.

Hoʻokumu ʻia ka inductor me nā mea kumu magnetic a me nā coils.E hoʻopili maoli ka inductor me ka capacitance stray i waena o kēlā me kēia coil, e hana ana i kahi kaapuni resonance like.No laila, e hoʻopuka ia i kahi Frequency Resonant Self (SRF).Ke ʻoi aku ka kiʻekiʻe o ke alapine ma mua o kēia, e hōʻike ka inductor i ka capacitance, no laila ʻaʻole hiki iā ia ke loaʻa hou ka hana mālama.No laila, ʻoi aku ka haʻahaʻa o ka hana ʻana o ka inductor mana ma mua o ke alapine resonant ponoʻī e hoʻokō i ka hopena mālama mālama.

I ka wā e hiki mai ana, e hoʻomohala ʻia ke kamaʻilio kelepona hele ʻana i ka hoʻouna ʻikepili kiʻekiʻe 4G/5G.Ua hoʻomaka ka hoʻohana ʻana i nā inductors i nā kelepona akamai kiʻekiʻe a me ka mākeke e hōʻike i ka ulu ikaika.Ma ka awelika, pono kēlā me kēia kelepona akamai i 60-90 inductors.Ma waho aʻe o nā modula ʻē aʻe e like me LTE a i ʻole nā ​​kiʻi kiʻi kiʻi, ʻoi aku ka nui o ka hoʻohana ʻana i nā inductors i ke kelepona holoʻokoʻa.

I kēia manawa, ke kumu kūʻai a me ka loaʻa kālā onā mea hoʻokomoHe kiʻekiʻe ke kiʻekiʻe i ka hoʻohālikelike ʻana i nā capacitors a i ʻole nā ​​​​mea pale, e huki ana i nā mea hana he nui e hoʻokomo i ka noiʻi a me ka hana ʻana.Hōʻike ka Figure 3 i ka hōʻike loiloi IEK e pili ana i ka waiwai inductor output a me ka mākeke, e hōʻike ana i ka ulu ikaika o ka mākeke.Hōʻike ka Figure 4 i ka nānā ʻana o ka nui o ka hoʻohana ʻana i ka inductor no nā polokalamu kelepona like ʻole e like me nā smartphones, LCDs, a i ʻole NB.Ma muli o ka nui o nā manawa ʻoihana i ka mākeke inductor, ke ʻimi nei nā mea hana inductor honua i nā mea kūʻai aku lima lima a me ka hoʻoikaika ʻana e hoʻolilo i ka noiʻi a me ka hoʻomohala ʻana i nā mea hou.mea hoʻokomo mananā huahana no ka hoʻomohala ʻana i nā polokalamu kelepona naʻauao kūpono a haʻahaʻa.

ʻO nā noi derivative o nā mana inductors ka mea nui i ka automotive, ʻenehana, a me nā huahana uila mea kūʻai aku.ʻOkoʻa nā ʻano a me nā kikoʻī o nā inductors mana e pili ana i kēlā me kēia kūlana noi.I kēia manawa, ʻo ka mākeke noi nui ka nui o nā huahana mea kūʻai aku.
