Choka inductor

DC resistance AC ndi njira yosavuta yonenera, imatha kudzipatula ndikuchepetsa chizindikiro cha AC, kapena kupanga dera lokhala ndi resistor ndi capacitor, kusintha chilankhulo ndikusankha pafupipafupi.Inductance coil ndi capacitor molumikizana zimatha kupanga LC tuning circuit.Ndiko kuti, ngati ma frequency oscillation achilengedwe 0 a dera ndi ofanana ndi ma frequency a siginecha ya AC, kuyankha kwamphamvu ndi capacitive reactance ya dera ilinso yofanana, kotero mphamvu yamagetsi yamagetsi imayenda mmbuyo ndi mtsogolo pakati pa inductor ndi capacitor. , chomwe ndi chodabwitsa cha dera la LC.Pamene resonant, inductive reactance ndi capacitive reactance ya dera imakhala yofanana ndi yobwerera kumbuyo, kotero kuti kachitidwe kameneka kameneka kamakhala kakang'ono, ndipo kuchuluka kwaposachedwa (kumatanthauza - 0 AC chizindikiro), kotero kuti LC resonant dera ili ndi ntchito yosankha ma frequency, ndipo imatha kusankha chizindikiro cha AC cha pafupipafupi.

Kukwera kwa ma frequency azizindikiro ndikosavuta, ndikosavuta kufalitsa.Komabe, mizere yama siginecha ambiri ilibe chotchinga.Mizere yama siginecha iyi imakhala tinyanga zabwino kwambiri zolandirira mitundu yonse yazizindikiro zowoneka bwino m'malo ozungulira.Ngati ma siginechawa ayikidwa pamwamba pa ma siginecha oyambira, amatha kusinthanso ma siginecha oyambira omwe adatumizidwa ndikusokoneza kwambiri magwiridwe antchito amagetsi, chifukwa chake ndikofunikira kuchepetsa kusokoneza kwamagetsi (EM) pazida zamagetsi.Pansi pakuchita kwa mphete ya maginito, ngakhale chizindikiro chodziwika bwino komanso chothandiza chikadutsa bwino, chimatha kupondereza chizindikiro chosokoneza kwambiri, ndipo mtengo wake ndi wotsika.Coil ya magnetic rod inductance imakhalanso ndi gawo lofunikira pakupitilira phokoso, chizindikiro chowunikira, kukhazikika kwapano komanso kupondereza kusokoneza kwa mafunde amagetsi.
