ʻO kahi inductor mode maʻamau'o ia ho'i, ua 'eha 'ia nā wili 'elua ma ke kumu hao ho'okahi, me nā wili kū'ē, ka helu o nā huli a me ka māhele like. Hoʻohana mau ʻia i ka hoʻololi ʻana i nā lako mana e kānana i nā hōʻailona hoʻopilikia electromagnetic mode maʻamau, hoʻohana ʻia nā kānana EMI e kāohi i nā nalu electromagnetic i hana ʻia e nā laina hōʻailona kiʻekiʻe mai ka hoʻomālamalama ʻana i waho. ʻO ka inductance mode maʻamau i ka hoʻokomo o ka module mana e hōʻemi i ka radiation a me ke alapine kiʻekiʻe. Eia nō naʻe, ʻoi aku ka maikaʻi o ka inductance maʻamau maʻamau i ka haʻahaʻa haʻahaʻa haʻahaʻa, a ʻoi aku ka maikaʻi o ke alapine kiʻekiʻe, akā ʻoi aku ka maikaʻi o ka manaʻo liʻiliʻi i ka haʻahaʻa haʻahaʻa.

Loaʻa iā ia ka hopena kaohi ʻana i ka walaʻau maʻamau. ʻO ke kumu hana ʻo ia ka wā e hele ai ke ʻano hana maʻamau i ka ʻāpana, ʻāwili nā inductances o nā inductors ʻelua. Akā no ka walaʻau ʻokoʻa, ua like nā inductances ʻelua me ka lawe ʻana i ka ʻokoʻa, emi ka waiwai inductance, a e nāwaliwali ka hopena suppression.

ʻO ka nui o ka inductance mode maʻamau e pili pono i ka hana EMC. ʻO ka hana nui e hoʻokaʻawale i ka hōʻailona mode maʻamau a hoʻemi i ka hoʻopili ʻana i ke ʻano maʻamau o waho, a laila e hōʻemi i ka hopena o ka mana. Hiki iā ia ke hōʻemi i ka hōʻailona mode maʻamau i loko a hoʻemi i ka hopena i ka pā mana. Eia nō naʻe, ʻoi aku ka maikaʻi o ka inductance maʻamau maʻamau i ka haʻahaʻa haʻahaʻa haʻahaʻa, a ʻoi aku ka maikaʻi o ke alapine kiʻekiʻe, akā ʻoi aku ka maikaʻi o ka manaʻo liʻiliʻi i ka haʻahaʻa haʻahaʻa.

ʻO ka mea maʻamau a mākou e hoʻohana ai ma ka hopena hoʻokomo o ka module mana he x hiki, y hiki a me ka inductance mode maʻamau. Loaʻa ka impedance haʻahaʻa i ka hōʻailona, ​​​​e hana ana ma ke ʻano he bypass a me ka hōʻailona hoʻohui. ʻO ka inductance ka impedance kiʻekiʻe i ka hōʻailona a hoʻokani i kahi hana i ka noʻonoʻo ʻana a me ka hoʻopili ʻana i nā hōʻailona interference kiʻekiʻe.

ʻO ka hoʻopaʻapaʻa ma waena o nā laina mana ʻelua i ka honua, ua kapa ʻia ʻo ia ka interference mode maʻamau, a ʻo ka interference ma waena o nā laina mana ʻelua i kapa ʻia ʻo ka ʻokoʻa mode interference. Ke hoʻohui ʻia ka inductance a me ka capacitance i kahi kānana, ʻoi aku ka maikaʻi o ka hopena kānana, a ʻo ke alapine alapine kahi e hana ai ka inductance a me ka capacitance. ʻOkoʻa nō hoʻi. Hiki i ka Y capacitor a me ka Y capacitor ke kānana i ka hoʻopili ʻana i ke ʻano maʻamau, a ʻo ka X capacitor ka mea nui e hana ma ke ʻano he hōʻailona pōkole, e hōʻemi ana i ke ala e kahe ai ka hōʻailona mode differential, a laila e hōʻemi i ka oscillation i hana ʻia e nā ʻāpana parasitic i loko. ke kaapuni a me ka hoʻokuʻu ʻana i nā alapine kiʻekiʻe.

Ke unuhi ʻia ka inductance a i ʻole capacitance i ka hoʻolālā, e hana mau ka ʻāpana i koe, akā ʻoi aku ka maikaʻi o ka hopena. Ma ka ʻōlelo maʻamau, ʻoi aku ka nui o ka impedance mode maʻamau, ʻoi aku ka maikaʻi. Ke koho ʻana i kahi inductor mode maʻamau, ʻo ke koho e pili ana i ka pihi pinepine impedance. I ka manawa like, pono e uku ʻia i ka mana o ka impedance mode differential ma ka hōʻailona.
