Kev siv hom hom inductors hauv kev hloov khoom siv hluav taws xob?
Hom hom choke, tseem hu ua hom hom choke, yog symmetrical winding ntawm coils nrog cov lus qhia rov qab thiab tib tus naj npawb ntawm tig ntawm lub nplhaib sib nqus. Qhov zoo tshaj plaws hom choke muaj qhov cuam tshuam rau kev cuam tshuam ntawm hom kev cuam tshuam ntawm L (lossis N) thiab E, thaum nws tsis muaj qhov cuam tshuam rau kev cuam tshuam ntawm kev sib txawv ntawm L thiab N. Txawm li cas los xij, tsis tiav symmetry hauv qhov tseeb coil winding tuaj yeem ua rau tiam ntawm kev sib txawv hom to to inductance. Thaum lub teeb liab tam sim no los yog lub hwj chim tam sim no ntws los ntawm ob lub windings nyob rau hauv cov lus qhia, lub generated magnetic flux rho tawm ib leeg tawm, thiab lub choke coil exhibits tsawg impedance. Thaum cov hom suab nrov nrov tam sim no (nrog rau qhov cuam tshuam tam sim no los ntawm lub voj hauv av, tseem hu ua longitudinal tam sim no) ntws los ntawm ob lub windings nyob rau tib txoj kev, cov sib nqus flux generated yog ntxiv rau tib txoj kev, thiab choke coil nthuav tawm siab impedance. , yog li suppressing hom suab nrov.
Hom hom inductor yog qhov tseem ceeb ntawm cov lim dej bidirectional: ntawm ib sab, nws yuav tsum tau lim tawm ntau hom electromagnetic cuam tshuam ntawm cov teeb liab kab, thiab ntawm qhov tod tes, nws yuav tsum txwv nws tus kheej los ntawm emitting electromagnetic cuam tshuam kom tsis txhob cuam tshuam rau kev ua haujlwm ib txwm muaj. lwm yam khoom siv hluav taws xob hauv tib qhov chaw electromagnetic.
Hom hom choke tuaj yeem xa cov teeb liab sib txawv, ob qho tib si DC thiab tsawg zaus sib txawv hom teeb liab tuaj yeem dhau los, thiab nws nthuav tawm qhov cuam tshuam loj rau cov suab nrov ntau zaus, yog li nws tuaj yeem siv los cuam tshuam hom kev cuam tshuam tam sim no.
Hom hom inductor, qee zaum kuj hu ua hom hom choke, yog siv los tua thiab feem ntau yog siv los hloov cov khoom siv hluav taws xob. Nws tsim ntau cov ntxaij lim dej los lim EMI thiab txo cov emission ntawm electromagnetic tsis generated los ntawm high-ceev teeb liab. Raws li pom nyob rau hauv daim duab hauv qab no, muaj ib txheej ntawm parallel kab hauv Circuit Court. Cov teeb liab ib txwm tsis cuam tshuam thaum dhau los, tab sis thaum muaj hom hom tam sim no ntws los ntawm, vim yog homogeneity ntawm hom tam sim no, ib qho chaw sib nqus nyob rau hauv tib qho kev taw qhia yog tsim nyob rau hauv lub kauj, nce lub inductance ntawm lub kauj thiab ua rau nws. tshwm sim siab impedance, ua ib tug muaj zog damping nyhuv. Lub sijhawm no, hom hom tam sim no yuav raug txo kom ua tiav lub hom phiaj ntawm kev cuam tshuam kev cuam tshuam.
