Kodi ma parameter a inductance ndi ati?

1. Quality factor factor factor:

Quality factor Q ndi chinthu chomwe chimagwiritsidwa ntchito kuyeza mgwirizano pakati pa mphamvu zosungidwa ndi zinthu zosungira mphamvu (ma inductors kapena capacitor) ndi kugwiritsa ntchito mphamvu zawo, zomwe zimafotokozedwa motere: Q = 2π kuchuluka kwa mphamvu zosungidwa / kutaya mphamvu kwa sabata. Nthawi zambiri, kukulira kwa mtengo wa Q wa coil inductance, ndizabwinoko, koma kukulira kwambiri kumapangitsa kukhazikika kwa dera logwirira ntchito kuipiraipira.

2, Inductance:

Pamene mphamvu ya koyilo ikusintha, kusinthasintha kwa maginito komwe kumadutsa pa coil loop komwe kumachitika chifukwa cha kusintha kwapano kumasinthanso, zomwe zimapangitsa kuti koyiloyo ipangitse mphamvu ya electromotive. Self-inductance coefficient ndi kuchuluka kwa thupi komwe kumayimira luso lodzipangitsa la koyilo. Imatchedwanso self-inductance kapena inductance. Imafotokozedwa ndi L. Kutenga Henry (H) monga gawo, gawo limodzi mwa chikwi chimodzi limatchedwa millihenh (mH), miliyoni imodzi imatchedwa millihenh (H), ndipo chikwi chimodzi mwa izo chimatchedwa Nahen (NH).

3. DC Resistance(DCR):

Pokonzekera inductance, kukana kwa DC kumachepetsa, kumakhala bwino. Muyeso woyezera ndi ohm, womwe nthawi zambiri umadziwika ndi kuchuluka kwake.

4, ma frequency a Self-resonant:

Inductor si chinthu chongowonjezera, komanso ili ndi kulemera kwa mphamvu yogawidwa. The resonance pa mafupipafupi ena chifukwa cha inductance chibadidwe ndi kugawa capacitance wa inductor palokha amatchedwa self-harmonic pafupipafupi, amatchedwanso resonance pafupipafupi. Kuwonetsedwa mu SRF, gawoli ndi megahertz (MHz).

5. Mtengo wolepheretsa:

Mtengo wa impedance wa inductor umatanthawuza kuchuluka kwa zopinga zake zonse zomwe zili pano (chiwerengero chovuta), kuphatikiza kulumikizana ndi magawo a DC. Mtengo wa impedance wa gawo la DC ndi kukana kwa DC kokha kwa mafunde (gawo lenileni), ndipo kufunikira kwa gawo loyankhulirana kumaphatikizapo kuyankha (gawo lolingalira) la inductor. M'lingaliro ili, inductor imathanso kuonedwa ngati "chotsutsana ndi kulankhulana". 6. Mawonekedwe apano: Mphamvu yamagetsi yopitilira ya DC yomwe imatha kudutsa pa inductor imaloledwa. Mphamvu yamakono ya DC imachokera pa kutentha kwakukulu kwa kutentha kwa inductor mu kutentha kwakukulu kowonjezera kozungulira. Zowonjezera zamakono zimagwirizana ndi kuthekera kwa inductor kuchepetsa kutayika kwa mafunde ndi kutsika kwa DC, komanso zokhudzana ndi mphamvu ya inductor kuti iwononge kutaya mphamvu yamagetsi. Chifukwa chake, zowonjezerapo zitha kupitilizidwa ndikuchepetsa kukana kwa DC kapena kukulitsa sikelo ya inductance. Pamafunde otsika pafupipafupi, muzu wake umatanthauza masikweya aposachedwa
