He aha ka ka manao lokahi inductance?

Ae hoʻokomo kŰia underlies he iiiaanoaa o ka pou manaʻo. Pinepine kulana, i ka wa a ke kanaka e pono 'alo a me kona hoike ana mai i ka maʻamau o ke ola, akā, e ole e ike e pili ana ia. E mākou hoole i ka hou i hala, ma ka papa kuhikuhiE ike EYI mea, he Analog lepa. Ano, aneane pau lolouila lako a pan i ua hoolilo i ka mīkini modulationʻAno. Ka nui, e hoike ana i ka "huahelu" uaʻoiʻike i nā mea a pau. Akā, e kahaha, i ka mea a me kēia? He oiaio, kekahi hale nō i ka ua hoʻouwea kelepona Kulekele Hoʻohanaʻia ka Analog PBX. Inā 'oe e hoohalike ai i ka laekahi "lawe lima nā kelepona'" a me ka "oldies", ke hoʻohālike mea pono,ʻaʻole ma ka lokomaikaʻiʻia mai o ka hope. E hoʻolohe maiʻoe ma luna o ke kāʻei kua o ka noho keʻakeʻa ka hoʻoleleʻana paha i ka "maikaʻi" hua'ōlelo mea no kekahi o ka hui ana - keia mea i mea hou. Keia hana no ka mea, i loko o ke kelepona uwea, na kaula e kokoke ana i kekahi i kekahi, no laila, he mea ka ae hoʻokomo i loko o ka laina elua. Kekahi laʻana o ka poe pulsating clicks hōʻike 'ia ma ka TV ka' ōlelo a me kāu kamepiula ka 'ōlelo, ka wā he mea mobilka, a ia mea he kahea. Eia hoi, ke kahiko IDE-uwea me 80 conductors i hoʻohana wale hapa o ia mau mea, i ka wā o ka 'ē aʻe 40 pale aku i ka hopena e lawe ae hoʻokomo. He nui examples, o ka hopena a pau, aole ia i hana pono. He nui wale e hoomanao ana i keia hihia, i kekahi "crosstalk" - keia mea i ka manao lokahi inductance.

Nui, i kēia manawa pili ana i ke kaʻina hana o ka hanana o ka electromotive ikaika (EMF) i loko o kekahi o ka pili conductors i ka manawa wā hoʻololi i loko o nā nouanoao?ʻikena waiwai. Loa wale hoakaka e ae hoʻokomo i ka mea hoʻololi uila. Ma kona simplest ano (he kūikawā hihia), ka mea hoʻololi uila maupaʻa mau coils wahi iho la ia ma ka iaʻume mākenēki Kora naʻEsau. I kaʻikena kahe ana ma ka uea o kekahi o ia mau mea, he mea puni kaʻume mākenēki kahua. Nolailaʻikeʻia ʻume mākenēki koko komo iloko o ka lua o ka'ōwili hao alakaʻi mele, e pili ana emf maloko. Ikea mai ia e poloʻai pule pono, nui, e pani i ka haʻina o ka'ōwili hao, e pili ana i ka kaulahao. Me ka mahuahua nui o kaʻume mākenēki koko ua mahuahua, a me ka manao lokahi inductance. E kū ai i ka makemake ano (e laʻa me, ka hoʻokōʻana) e hoʻohana okoa pāʻoihana: hoʻololi i ka hoʻonohonohoʻia o kaʻume mākenēki puni; ua hana kūikawā ala i nāʻanuʻu coils, a ua ana me ka variometer Ave. ae inductance.

Pehea ka mea hoike ma ka olelo mua aku i loko o kēia 'atikala i ka examples? Loa puni hoʻi: i aneane na hihia a pau (koe wale no ka lawe lima nā kelepona ') i kahi kokoke i kekahi mau conductors, ma ka liʻiliʻi loa kekahi o i hele i ka pilaʻikena. Nolaila, he mea heʻume mākenēki kahua hoʻomakaʻiaʻume mākenēki koko. Ka hope, penetrating kokoke conductors induces EMF i loko o ia mau mea, e like me ka pono me ke kaula nei, alaila, ma ka like ana me ke kānāwai o ka electromagnetic a hoʻokomo, heʻikena lua i pele. Kona kuhikuhi ana me ka nānā 'ana ana i ka rula o Lenz.

Manao lokahi hoʻomano hoʻohana 'ia i loko o ke kālā no ka hana' enekinia uila. Mai kekahi o kona undesirable 'ole i helu mua i loko o keia' atikala, ka mea i pono, e haawi examples o maikaʻi kēia. Kekahi o ka loa loa-ike i na mea maalea - hale stabilizer ka papa kuhikuhi. I loko o ka mea, he mea hoʻololi uila (IeAUPIIe, IAa IO he toroid type) me ka ai iiiaanoaa o ka maʻi, kela mea keia mea o ka i hoʻopili like i ka kekahi anakahi uila waiwai. Nō hoʻi, i loko o kekahi mea, he manaʻo 'oe ke' imi i ka hana hoihoi pāʻoihana - galvanic hoʻokaʻawale. I mea, keia mea i ka ua mea hoʻololi uila (kekahi manawa photocoupler mau), akā,ʻaʻole hoʻohana i ka hou 'kaʻi lau waiwai. E like me ka hopena, hiki e hanaʻume mākenēki koko ma mau kamaʻilio mau kuamoo, hoomaopopo ana i ka pono nui o ka uila maluhia. -I? Iecaianoaaiiuo laʻana, ia davit.
