Chip inductance

Lub nti inductor yog ib qho electromagnetic induction lub qhov txhab nrog ib tug insulated hlau. Nws yog ib qho khoom siv feem ntau siv inductive. Lub luag haujlwm ntawm cov nti inductor: los ntawm DC tsis kam AC yog cov lus yooj yim, AC teeb liab raug rho tawm, lim los yog ua ke nrog cov capacitors, resistors, thiab lwm yam los tsim ib lub voj voog resonant. Tuning thiab zaus xaiv inductance: lub inductor thiab capacitor nyob rau hauv parallel tuaj yeem tsim LC Tuning lub Circuit Court. Txhua qhov tam sim no nyob rau hauv Circuit Court ntawm lub nti inductor tsim ib qho chaw sib nqus uas ua rau hauv Circuit Court.

Thaum cov tam sim no los ntawm cov nti inductor hloov, DC voltage muaj peev xwm tsim nyob rau hauv nti inductor yuav tiv thaiv qhov tam sim no los ntawm kev hloov. Thaum cov tam sim no los ntawm inductor nce, tus kheej-induced electromotive quab yuam generated los ntawm inductor kauj yog opposite rau cov kev taw qhia tam sim no, tiv thaiv qhov nce ntawm tam sim no, thiab converting ib feem ntawm lub zog hluav taws xob mus rau hauv ib tug magnetic teb yuav khaws cia nyob rau hauv lub inductor. inductor; Thaum qhov tam sim no los ntawm inductor raug txo, Tus kheej-induced electromotive quab yuam nyob rau hauv tib txoj kev raws li qhov tam sim no, tiv thaiv qhov tam sim no los ntawm kev txo qis thiab ib txhij tso tawm lub zog khaws cia kom them rau qhov txo tam sim no. Yog li ntawd, tom qab lub inductor lim, tsis tsuas yog lub ripple ntawm lub load tam sim no thiab voltage yog txo, lub waveform yuav du, thiab lub conduction lub kaum sab xis ntawm lub rectifier diode nce.

Lub luag hauj lwm ntawm inductor 1: xim nplhaib inductance muaj qhov cuam tshuam los thaiv: cov tub ntxhais tooj liab hauv cov xim nplhaib inductor coil yeej ib txwm tiv taus qhov tam sim no hauv lub kauj. Cov xim nplhaib inductance muaj qhov cuam tshuam rau qhov hloov pauv tam sim no siv hauv Circuit Court, thiab qhov loj ntawm cov nyhuv thaiv yog hu ua XL, thiab chav tsev yog ohm. Kev sib raug zoo ntawm inductance L thiab AC zaus f yog XL=2πfL, thiab xim nplhaib inductance tuaj yeem muab faib ua ntau zaus choke coil thiab qis zaus choke coil.

Lub luag hauj lwm ntawm lub inductor 2: xim nplhaib inductance muaj kev tuning thiab zaus xaiv: xim nplhaib inductance thiab electrolytic capacitor nyob rau hauv parallel tuaj yeem tsim LC tuning circuit. Thaum cov xim-ntiv nplhaib inductance resonates, inductive reactance thiab capacitive reactance ntawm Circuit Court yog thim rov qab. Ntawd yog, lub ntuj oscillation zaus f0 ntawm Circuit Court yog sib npaug rau qhov zaus f ntawm lub teeb liab tsis-AC, thiab inductive reactance thiab capacitive reactance ntawm lub voj kuj sib npaug. Kev siv feem ntau tsis siab heev, thiab cov xim nplhaib inductance siv nyob rau hauv Circuit Court yog feem ntau ruaj khov.

Lub luag hauj lwm ntawm inductor 3: Qhov siab tshaj plaws xim-ntiv nplhaib inductance tsuas yog siv cov teeb liab lim, lim suab nrov, stabilizing tam sim no thiab suppressing electromagnetic cuam tshuam. Lub luag haujlwm tseem ceeb ntawm cov xim-ntiv nplhaib inductor yog them thiab tawm, tab sis ntau qhov tshwm sim hauv Circuit Court txuas ntxiv los ntawm qhov yooj yim them thiab tawm cov nyhuv ua rau cov xim nplhaib inductance muaj ntau yam kev siv. Niaj hnub no, cov xim-ntiv nplhaib inductors tau siv los ntawm cov neeg siv khoom, thiab lub luag haujlwm ntawm cov inductors me tsis raug saib xyuas.
