Kauj Transformer: Kis kab Equalizer (balun) txojcai, tsim, Fabrication thiab soj ntsuam

Ib tug neeg tuaj balancer (Barron)

Balancer baron Balancing ntaus, nws tseem ceeb muaj nuj nqi yog accomplished ntawm tib ended tau (xws li tus kab coaxial thiab microstrip kab etc.) yog transformed rau hauv kis plawg (xws li: kav hlau txais xov dipole yoj ib nrab, rub laub Circuit Court etc.) ntawm transformation, los yog cov balun yog tshuav nyiaj li cas-Unbalance, Hmong tshuam abbreviated ua ib lo lus Balun, transliterated li baron. Balancer, tshuav - hereinafter xa mus rau hauv lub converter kauj, balun, yog hais txog cov no qhia ntaus ntawv.

Balun balancer (balun) lug siv rau hauv xov tooj cua, vim nws cov cai hais txog ntau yam ntxwv, haiv neeg lus thiab chav yuav sib, muab txoj kev phooj ywg ntau rau nws tus kheej made balun balancer (balun) thaum tsis muaj tus pib lawm rau dab tsi? Li cas los xaiv cov khoom? Li cas los laij cov ntau lawm tsis? Li cas los ntsuas txoj kev kawm ntawm cov Baron? Rau peb amateur, mas siv cov kav hlau txais xov pub thiab loj zog amplifier, ntawv lub luag hauj lwm ntawm kauj thiab impedance transformation, ua hauj lwm nyob hauv lub luv yoj tes 1.8 MHZ ~ 30 MHZ, thiab yuav tsum muaj ntaub ntawv thiab ntau lawm yog ib qho yooj yim. Ua ntej peb nkag siab txog lub balun, tias tus tsa los ntawm kis kab balun, ntau tsis tsim kom muaj kev sib txuas lus shortwave, nws txoj kev kawm zoo, yooj yim, thiab yooj yim rau manufacture, tab sis tsis yooj yim rau to taub, nws yuav muaj txoj kev phooj ywg nyob rau hauv ib coupling sib nqus transformer qauv heev rau ziag no zoo nkaus li nqaim zaus qhab, peev xwm fais fab me me, thoob yoj sis tsis ncaj kiag, cov qhabnias txog cov nyhuv uas kis kab transformer tsis muaj.

Ob tug, tus kis kab equalizer (Barron yooj yim txojcai)

Balun balancer (balun) muaj ntau yam, raws li qhov nqi koj tshuav cov neeg mob yuav tau muab faib ua plaub yam tam sis: txham hom (teeb unbalance tam sim no) thiab yam (rau cov impedance, inverter inverted (kuas) voltage) thiab sib nqus coupling (conjugate tam sim no). Ntawm no kuv mas piav cov kis kab transformer balun transforms le impedance transformation muaj nuj nqi uas balun, muaj ib tug xeeb ceem ntaus txhawm chim thiab hom sib nqus coupling.

Tus tsa los ntawm kis kab transformer winding raws li hais saum toj no, nws yog ib los yog ob peb pawg uas kis kab loj sib nqus nplhaib, siv hom kev twb kev txuas txoj kev mus ua kom tiav cov impedance transformation thiab balun transformation. Los pib lub converter zog rau cov davhlau ya nyob twg kis mus rau cov ceevxwm uas kis kab capacitance, inductance thiab electromagnetic zog txauv, qhov no feem ntau nyob ib ncig ntawm lub transformer, nws overcomes tus coils hauv loj transformer vim phiv los ntawm tus distributed capacitance kauj, zoo xeeb ceem zaus. Ntxiv mus, uas ob tug sib npaug zos amplitude rau txhua neeg xyuas pib tam sim no kis kab rau qhov cuag, lawv ua nyob hauv tus tub ntxhais flux offset sib, ces tub ntxhais tsis tau tseem me heev, txawm tias cov ntxhais sectional chaw me me, tab sis kuj muaj peev xwm hwj chim siab. Yog li ntawd, nws muaj qhov zoo dav zaus qhab, me, peev xwm loj zog thiab hais txog,

Yuav kis tau tus mob kab transformer hauv tsawg zaus tshaj rau cov tshuaj tsawg zaus converter, deterioration uas yuav teb zaus yog vim kis kab ntawm ob thaum uas tig mus hluav taws xob conductors vim magnetizing inductance los ntawm naj, nws txiav txim rau yam tsawg kawg ua hauj lwm zaus converter.

Thaum kawg nws yog tus loj kis kab tus yam ntxwv ntawm tus impedance, kom tsis txhob muaj resonance phenomenon, tshwj xeeb tshaj yog rau txoj load, nws yuav muaj kev nce fluctuations tshuam, qhov ntev ntawm txoj kev kis tau tus mob kab tsis pub tshaj cov txwv lub zaus ntawm 1/8 wavelengths, tus yam ntxwv tsis ntev tsawg zaus heev.

Thiaj li xaiv tau cov ntxhais magnetic rau lub RF transform, nws yuav tsum paub hais tias cov saturation magnetic flux thiab cov yam ntxwv nonlinear, los xam qhov nyiaj pab ntau tshaj magnetic flux ceev raws li ntau zog tus khiav hauj lwm tsawg zaus.

Vim nws siv tau kab converter balun transforms, kom thaum kawg muaj ceeb thawj kauj seem. Cov tseem ceeb indicators, As no balun transform, yuav siv tau zoo sib xws Circuit Court ntau hom teeb liab thiab teeb liab plawg hom los qhia cov kauj teeb liab thiab teeb liab kuas, nws inhibit tau qhia txog tej yam no kuv xav tias tus Performance index uas muaj ntau hom, yuav tsum hu ua kauj inhibition. Nws yuav cuam tshuam dab tsi los piv rau ntawm tus impedance transformation, tiam sis kuj yog tej yam uas muaj ntau hom inductance.

Peb, cov kis kab balancer (kav ywm Lun) siv lub muab xam software

Raws li tus cai hais saum toj no, yog muab tej yam muab xam mis mos, tab sis kev yog ib rooj plaub - thiab ces suav tus haum tsis mus kho, nrhiav qhov txheeb xyuas tau tias lawv tsis tsim yuj yees ob peb zaug, ib lub caij, cov tsis muaj cov tub ntxhais magnetic yeej paub txog, yog li ntawd, kuv chav uas muaj cov yam ntxwv ntawm kis kab transformer kev nkag siab thiab balun thiab rau txoj kev tau taub ntawm cov tub ntxhais , sim ib rau qhov muab xam los ntawm cov kis kab balun sau tau ib cov software uas me me, hoping yuav kom daws tau cov teeb meem ntawm kev tuav muab xam.

Tom qab khiav software cov xws li qhov rais, ua hauj lwm ntau zaus, kis kab balun tsim thov input qhov tsawg tshaj plaws ua hauj lwm zaus, ntau zog thiab tus xaiv ib ntiv nplhaib tawm thiab puv ib ncig lub nplhaib, naj npawb rau lub xaus thawj ob yog ob tug ntiv nplhaib txoj kab uas hla nruab nrab yog cov khoom uas muaj cov khoom sib txawv, tau ua payment rau thawj thawj zaug xaiv ib txoj kev kuaj , koj lem ntawm tus coils yuav tsis sau ib integer, xws li 10, thiab ces nias rau lub andquot; calculateandquot; khawm, cov tsawg yog kaum yuav tsum tau kho tus tsis ua raws li kev ntsuam, tom los xam, txog thaum ib tug ntog fee, yog hais tias tsis tau ntaus nqe hnyav tau, nws yuav tsum zaus los ntawm ntau yam yog dav heev, los sis sim ntau fais fab, tsim nyog yuav txo ib txhia.

Plaub, tus kis kab balancer (tshuaj ntsuam Barron)

1, cov Bobbi, cov ntau hom rejection piv, tsis zoo:

A. Bobbi - tus tso zis kuas cov kav ywm Lun ces matched los tus cuav load, uas yog siv los ntsuas cov thoob hauv lub coaxial davhlau ya nyob twg hauv lub zaus qhab.
