Xaiv qhov tsim nyog inductor rau kev hloov fais fab | TAU TXAIS

Kev tsim hluav taws xob inductor chaw tsim tshuaj paus qhia koj

Ib inductor , tseem hu ua choke, yog tus cwj pwm los ntawm "zoo inertia" ntawm qhov tam sim no ntws los ntawm nws. Hauv lwm lo lus, vim qhov txuas ntxiv ntawm cov flux, qhov tam sim no ntawm lub inductor yuav tsum tau txuas mus ntxiv, txwv tsis pub nws yuav ua rau lub zog loj. Lub inductor yog cov khoom sib nqus, yog li nws ib txwm muaj teeb meem ntawm kev sib nqus saturation. Qee daim ntawv thov tso cai rau inductance saturation, qee daim ntawv thov tso cai rau cov inductors nkag saturation los ntawm qee tus nqi tam sim no, thiab qee cov ntawv thov tsis tso cai rau inductors kom saturated, uas yuav tsum muaj qhov sib txawv hauv cov circuits tshwj xeeb.

Feem ntau, cov inductor ua haujlwm nyob rau hauv "linear cheeb tsam", qhov twg cov inductance yog qhov tas li thiab tsis hloov nrog lub davhlau ya nyob twg voltage thiab tam sim no. Txawm li cas los xij, muaj ib qho teeb meem uas tsis tuaj yeem tsis quav ntsej, uas yog, winding ntawm lub inductor yuav ua rau ob qhov kev faib tsis tau (lossis tsis muaj kab mob), ib qho yog qhov tsis tuaj yeem tiv thaiv winding, lwm qhov yog qhov kev faib tawm tsis zoo cuam tshuam nrog lub winding. txheej txheem thiab cov ntaub ntawv.

Stray capacitance tsis tshua muaj txiaj ntsig ntawm qhov tsawg zaus, tab sis nws maj mam tshwm nrog qhov nce ntawm zaus. Thaum cov zaus yog siab tshaj ib qho nqi, tus inductor yuav dhau los ua tus yam ntxwv ntawm lub cev. Yog hais tias lub stray capacitance yog "ntseeg" rau hauv lub capacitor, cov yam ntxwv ntawm lub capacitance tom qab qee zaus tuaj yeem pom los ntawm qhov sib npaug ntawm qhov inductor.

Kev ua haujlwm ntawm inductor hauv Circuit Court

Ib yam li lub capacitor muaj tus nqi thiab tawm tam sim no, lub inductor kuj muaj cov txheej txheem them nqi thiab tawm hluav taws xob. Qhov voltage ntawm lub capacitor yog proportional rau qhov tseem ceeb ntawm qhov tam sim no, thiab tam sim no ntawm lub inductor yog proportional rau qhov tseem ceeb ntawm qhov voltage. Ntev npaum li qhov inductor voltage hloov, tam sim no tus nqi hloov di / dt kuj yuav hloov; lub zog pem hauv ntej ua rau tam sim no nce linearly, thiab qhov rov qab voltage ua rau tam sim no linearly txo.

Nws yog ib qho tseem ceeb heev los xam qhov tseeb inductance los xaiv qhov tsim nyog inductor thiab tso zis capacitor kom tau txais qhov tsawg kawg nkaus tso zis voltage ripple.

Inductance xaiv ntawm kauj ruam-down switching Fais fab mov

Thaum xaiv cov inductors rau puck switching fais fab mov, nws yog ib qho tsim nyog los txiav txim siab qhov siab tshaj plaws input voltage, tso zis voltage, fais fab hloov zaus, qhov siab tshaj plaws ripple tam sim no thiab lub voj voog ua haujlwm.

Inductance xaiv ntawm boost switching Fais fab mov

Rau qhov inductance xam ntawm boost switching fais fab mov, tshwj tsis yog tias kev sib raug zoo ntawm lub voj voog lub luag hauj lwm thiab inductance voltage tau hloov, lwm cov txheej txheem yog tib yam li cov kauj ruam-down switching fais fab mov.

Thov nco ntsoov tias tsis zoo li cov khoom siv fais fab, qhov kev thauj khoom tam sim no ntawm lub zog txhawb zog tsis yog muab los ntawm cov khoom siv tam sim no. Thaum lub raj hloov pauv, lub inductor tam sim no ntws mus rau hauv av los ntawm kev hloov lub raj, thiab lub load tam sim no yog muab los ntawm cov zis capacitor, yog li cov zis capacitor yuav tsum muaj lub peev xwm loj txaus los muab qhov tam sim no xav tau los ntawm cov khoom thauj. lub sijhawm no. Txawm li cas los xij, thaum lub sij hawm tig-tawm ntawm kev hloov, qhov tam sim no ntws los ntawm inductor tsis tsuas yog muab cov khoom thauj, tab sis kuj them tus nqi tso tawm capacitor.

Feem ntau hais lus, thaum tus nqi inductance loj dua, cov zis tawm ripple yuav me dua, tab sis cov lus teb dynamic ntawm lub hwj huam mov kuj yuav ua phem dua, yog li kev xaiv tus nqi inductance tuaj yeem hloov kho raws li cov kev thov tshwj xeeb ntawm Circuit Court kom ua tiav. qhov zoo tshaj plaws.

Qhov nce ntawm kev hloov zaus tuaj yeem ua rau inductance me dua, kom lub cev qhov loj me ntawm inductor ua me dua thiab txuag lub rooj tsav xwm hauv Circuit Court, yog li tam sim no hloov hluav taws xob hloov pauv muaj qhov sib txawv mus rau qhov ntau zaus, txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom siv me me. ntim ntawm cov khoom siv hluav taws xob.

Cov saum toj no yog cov kev taw qhia ntawm kev xaiv cov inductor tsim nyog rau lub switching fais fab mov. Yog tias koj xav paub ntau ntxiv txog cov inductor, thov koj xav tiv tauj peb.
