Phunzirani kuchuluka kwa inductance yofananira . Tsatirani wopanga inductance (woperekedwa mwaluso: inductor ofananira, Zogulitsa Zotentha zozungulira inductor) kuti muphunzire:
Njira zosiyanitsira pakadali pano: Zizindikiro ziwiri zofananira ndi kulumikizana kwina pamizere iwiri yosiyana, yomwe imagwiritsidwa ntchito mozungulira
Pakadali pano, pamzera wamagetsi, ndikomwe kukuyenda pakati pa mzere wazizindikiro ndi malo olowera.
Mawonekedwe wamba: Zizindikiro (kapena phokoso) zofananira ndi kulondola pamizere iwiri yazizindikiro.
Nthawi zambiri, phokoso la pansi limafalikira ndi njira wamba, motero limatchedwanso phokoso wamba.
Pali njira zambiri zothetsera phokoso lodziwika bwino. Kuphatikiza pakuchepetsa phokoso lazomwe zimayambira poyambira, magwiridwe antchito wamba amagwiritsidwa ntchito kusefa phokoso lanyimbo, ndiye kuti, kutsekereza phokoso lamtundu wamba kuchokera mdera lomwe mukufuna. Cholinga ndikukulitsa kutsekeka kwa dera lofananira kuti magwiridwe antchito azikudya ndi kutsekedwa (kuwonetsedwa) ndikutsamwitsidwa, potero kumachepetsa phokoso lofananira mderalo.
Mfundo yodziwika bwino kapena kutsika kwa inductor
Ngati ma coil awiri amamangiriridwa mbali imodzimodzi pa mphete yamaginito yamagetsi, maginito othamangitsidwa amapangidwa mu koyilo chifukwa cha kupatsidwa mphamvu kwamagetsi pakadali pano njira ina yodutsamo imadutsa pa coil. Mphete yamaginito ndiyofanana kukula kwake ndi mbali ina, ndipo awiriwo amaletsana, kotero mawonekedwe amtundu wa impedance omwe amapangidwa ndi mphete yamaginito ndi ochepa kwambiri.Pazizindikiro zofananira, maginito opangidwa ndi ofanana kukula kwake Khalidwe ili limapangitsa kuti magwiridwe antchito wamba azikhala ndi mphamvu zochepa pazizindikiro zakusiyanaku ndipo ali ndi magwiridwe antchito paphokoso lamtundu wamba.
(1) Pamene masiyanidwe mumalowedwe apano akudutsa koyilo wamba, maginito mzerewo amakhala mbali ina ndipo maginito opangitsa mphamvu afooka. Zitha kuwonedwa kuchokera kulumikizidwe kwa maginito mzere womwe uli pansipa kuti muvi wolimba umayimira kuwongolera kwamakono ndipo mzere wodutsa ukuimira kulowera kwa maginito
(2) The wamba-mode panopa akudutsa koyilo wamba-mode, ndi maginito ndi kumalimbitsidwa chifukwa malangizo omwewo a mzere maginito. Zitha kuwonedwa kuchokera kulumikizidwe kwa maginito mzere womwe uli pansipa kuti muvi wolimba umayimira kuwongolera kwamakono ndipo mzere wodutsa ukuimira kulowera kwa maginito
Kukhazikika kwapa coil komwe kumatchedwa coil kapena komwe kumadziwika kuti kudziyimira pawokha, tikudziwa kuti inductance imatulutsa mphamvu yamaginito, magwiridwe antchito kapena koyilo wamba wa inductor, pomwe njira yofananira ikadutsa kolowera, chifukwa cha mizere yamagawo amtundu womwewo, osaganizira momwe kutayikira kumayendera, maginito othamanga, mfundo zake ndizophatikizana, pansipa mizere yama coil yamagetsi kudzera mumizere yama buluu, yofiira komanso yabuluu red koyilo, kupatsidwa ulemu wina ndi mzake.
From the point of view of inductance, inductance is multiplied, magnetic chain represents the total magnetic flux, the common-mode inductor, when magnetic flux is doubled, circle number has not changed, the current didn't also did not change, so mean increased inductance for 2 times, means that the equivalent permeability into 2 times.
Kodi kuloleza kofananira kumatha bwanji kuwirikiza? Kuchokera pamtundu wotsatira wa inductance, popeza kuchuluka kwa kutembenuka kwa N sikusintha, maginito oyenda ndi gawo lamagawo am'maginito amatsimikizika ndi kukula kwa maginito, kotero palibe kusintha. Chifukwa chokha ndikuti kuloleza U kumachulukitsidwa, kotero maginito ochulukirapo amatha kupangidwa
Common-mode inductor in common mode, therefore, when an electric current passes through, work under the mutual inductance model, under the effect of mutual inductance, the equivalent inductance is cost increase, therefore common mode impedance will be multiplied, and the common mode signal has good filtering effect, also is the common mode signal with large impedance block, don't let it pass the common-mode inductor, also is not to let this signal transmission to the next level of the circuit, the following is the inductive reactance ZL.
Know common-mode inductor under the mode of common mode inductance, is the main clue to know mutual inductance, magnetic components of all, no matter what name as long as mastering the form of the change of the magnetic field, magnetic field changes through the phenomenon to essence, also easy to understand, moreover we always grasp the magnetic field lines, it is our understanding the visual form of the magnetic field, consider whether the same side or different name or concept of the mutual inductance phenomenon or magnetic field, we are drawing the lines of magnetic force to realize their - master "magnet winding method" is explained before.
