Nyob rau hauv tus txheej txheem tsim ntawm lub hwj chim transformer, engineers yuav tsum nruj me ntsis xam thiab ua kom tiav tus tsim thiab cov zauv xaiv ntawm hom hom inductance, uas yog ncaj qha cuam tshuam rau kev khiav hauj lwm raug ntawm lub switching zog transformer. Nyob rau hauv tsab xov xwm niaj hnub no, peb yuav piav qhia luv luv ntawm cov hom inductance tsim ntawm kev hloov hluav taws xob hloov hluav taws xob, thiab pom tias muaj teeb meem dab tsi yuav tsum tau them nyiaj rau hauv kev tsim thiab suav ntawm hom hom inductance ntawm lub zog transformers. Hauv kev tsim thiab tsim cov txheej txheem ntawm lub hwj chim transformers, engineers yuav tsum tsim cov hom inductance, thiab muaj peb yam tseem ceeb uas yuav tsum tau muaj, xws li cov tswv yim tam sim no, impedance thiab zaus, thiab xaiv cov tub ntxhais sib nqus. Cia peb xub saib cov tswv yim tam sim no. Tus nqi ntawm qhov ntsuas no ncaj qha txiav txim siab cov kab hlau uas xav tau rau lub winding. Thaum xam thiab xaiv cov hlau txoj kab uas hla, qhov ceev tam sim no feem ntau yog 400A / cm³, tab sis tus nqi no yuav tsum hloov nrog qhov kub ntawm qhov inductor. Feem ntau, cov windings yog khiav nrog ib lub xaim, uas txo cov suab nrov nrov thiab cov tawv nqaij poob. Nyob rau hauv cov txheej txheem kev suav, qhov impedance ntawm hom hom inductance ntawm lub zog hloov hluav taws xob hloov pauv feem ntau tau teev tseg raws li qhov tsawg kawg nkaus tus nqi raws li qhov muab zaus. Lub linear impedance nyob rau hauv series muab lub suab nrov nrov attenuation. Tab sis qhov tseeb, qhov teeb meem ntawm linear impedance feem ntau tsis saib xyuas, yog li cov neeg tsim qauv feem ntau siv 50W linear impedance stabilization network ntsuas los ntsuas cov hom inductors, thiab nws tau maj mam dhau los ua qauv qauv los ntsuas kev ua haujlwm ntawm hom inductors. Txawm li cas los xij, cov txiaj ntsig tau txais feem ntau txawv ntawm qhov tseeb. Qhov tseeb, lub ces kaum zaus ntawm hom hom inductor yuav xub tsim qhov nce ntawm -6dB attenuation ib octave ntawm lub sij hawm ib txwm muaj (lub kaum zaus zaus yog qhov zaus uas hom hom inductor tsim -3dB). Lub kaum zaus zaus no feem ntau yog qis kom qhov inductive reactance tuaj yeem muab impedance. Yog li, qhov inductance tuaj yeem qhia los ntawm cov qauv no, uas yog: Ls=Xx/2πf. Muaj lwm qhov teeb meem uas cov engineers yuav tsum tau them sai sai rau, uas yog, cov khoom siv tseem ceeb thiab tus lej yuav tsum tau ua yuav tsum tau them sai sai rau thaum tsim cov hom inductor. Ua ntej tshaj plaws, cia peb saib cov kev xaiv ntawm cov qauv sib nqus core. Yog tias muaj qhov chaw inductance tshwj xeeb rau lub sijhawm no, peb yuav xaiv cov qauv sib nqus hlau tsim nyog raws li qhov chaw no. Yog tias tsis muaj kev cai, cov qauv hlau nplaum feem ntau yog xaiv ntawm qhov xav tau. Tom qab txiav txim siab hom tub ntxhais ntawm lub hwj chim transformer, txoj hauj lwm tom ntej yog xam qhov siab tshaj plaws ntawm cov lem uas cov tub ntxhais yuav ua tau. Feem ntau hais lus, ib hom hom inductor muaj ob lub windings, feem ntau ib txheej, thiab txhua qhov winding raug faib rau txhua sab ntawm cov tub ntxhais sib nqus, thiab ob lub windings yuav tsum tau sib cais los ntawm qee qhov kev ncua deb. Ob chav thiab stacked windings kuj tau siv qee zaus, tab sis txoj hauv kev no ua rau kom muaj kev faib tawm ntawm cov winding thiab txo qhov kev ua haujlwm siab ntawm inductor. Txij li cov hlau txoj kab uas hla ntawm cov tooj liab hlau tau raug txiav txim siab los ntawm qhov loj ntawm cov kab hluav taws xob tam sim no, lub voj voog sab hauv tuaj yeem suav tau los ntawm kev rho tawm lub vojvoog ntawm cov hlau tooj liab los ntawm lub voj voog sab hauv ntawm cov hlau nplaum. Yog li ntawd, qhov siab tshaj plaws ntawm cov lem tuaj yeem xam los ntawm cov kab uas hla ntawm cov tooj liab hlau ntxiv rau kev rwb thaiv tsev thiab qhov ncig ntawm txhua qhov winding.
