Hom hom choke coil yog ib feem tseem ceeb ntawm kev hloov fais fab mov, zaus converter, UPS fais fab mov thiab lwm yam khoom siv. Ua hauj lwm hauv paus ntsiab lus ntawm inductor: Thaum lub sij hawm ua hauj lwm tam sim no ntws los ntawm ob coils raug mob nyob rau hauv opposite lus qhia, ob magnetic teb H1 thiab H2 uas tshem tawm ib leeg tawm yog generated. Nyob rau lub sijhawm no, kev ua haujlwm tam sim no feem ntau cuam tshuam los ntawm damping ntawm lub coil lub ohmic tsis kam thiab me me to inductance ntawm negligible ua hauj lwm zaus. Yog tias muaj cov teeb liab cuam tshuam ntws los ntawm inductor, lub inductor yuav pom cov impedance siab, ua kom muaj zog damping cuam tshuam rau attenuate cov teeb liab cuam tshuam.
1.Txoj kev piav qhia ntawm lub hauv paus ntsiab lus ntawm kev ua haujlwm, kev ua haujlwm, cov yam ntxwv thiab kev siv ntawm hom hom choke coil:
Hom hom choke coil yog ib feem tseem ceeb ntawm kev hloov fais fab mov, zaus converter, UPS fais fab mov thiab lwm yam khoom siv. Nws txoj hauv kev ua haujlwm: Thaum lub sijhawm ua haujlwm tam sim no ntws los ntawm ob lub coils qhov txhab nyob rau hauv cov lus qhia sib txawv, ob qhov sib nqus H1 thiab H2 uas tshem tawm ib leeg tawm. Nyob rau lub sijhawm no, kev ua haujlwm tam sim no feem ntau cuam tshuam los ntawm damping ntawm lub coil lub ohmic tsis kam thiab me me to inductance ntawm negligible ua hauj lwm zaus. Yog tias muaj cov teeb liab cuam tshuam ntws los ntawm lub kauj, lub kauj yuav pom cov impedance siab, ua kom muaj zog damping cuam tshuam kom txo cov teeb liab cuam tshuam.
2.Functions ntawm hom hom choke coil:
Hom hom choke coil yog qhov tseem ceeb ntawm cov lim dej bidirectional: ntawm ib sab, nws yuav tsum lim tawm cov hom kev sib nqus electromagnetic cuam tshuam ntawm cov teeb liab kab; Ntawm qhov tod tes, nws yuav tsum tau txwv nws tus kheej electromagnetic cuam tshuam los ntawm emitting tawm sab nraud, tsis txhob cuam tshuam rau kev ua haujlwm ntawm lwm cov khoom siv hluav taws xob hauv tib qhov chaw electromagnetic. Hom hom choke coil tuaj yeem xa cov teeb liab sib txawv, DC thiab cov cim hom sib txawv nrog cov zaus qis heev tuaj yeem dhau mus, thaum nws nthuav tawm qhov loj impedance rau high-frequency hom suab nrov, uas tuaj yeem siv los cuam tshuam hom kev cuam tshuam tam sim no.
3.Cov yam ntxwv ntawm hom hom choke coil:
Hom hom choke coil txais yuav ferrite core thiab ob-xaim winding, nrog rau hom hom suab nrov nrov thiab tsis tshua muaj suab nrov sib txawv hom teeb liab muaj peev xwm. Nws yog ib qho nyuaj rau deform nyob rau hauv high-speed signals, me me, yooj yim rau siv, thiab muaj zoo heev tshuav nyiaj li cas, yooj yim ntawm kev siv, siab zoo, thiab lwm yam zoo. Tsis tas li ntawd, nws muaj impedance me me nyob rau hauv kev ua hauj lwm zaus band, loj impedance ntawm qhov cuam tshuam zaus, ruaj khov inductance tus nqi, zoo thermal stability, thiab ntau yam qauv thiab impedance yam ntxwv yuav xaiv tau.
Kev siv txhua hnub ntawm hom hom choke coil:
1.Switching fais fab mov suab nrov suppression lim
2.Electrostatic suab nrov lim rau cov kab hluav taws xob thiab cov teeb liab kab
3.Radiation cuam tshuam suppressor rau converters thiab ultrasonic khoom, thiab lwm yam.
