Yuav Ua Li Cas Xaiv Txoj Cai Fais Fab Inductor
Kev txiav txim siab ntau yam ntawm inductances
Lub ntsiab lus pib zoo yog txiav txim siab qhov ntau ntawm inductances uas yuav ua haujlwm hauv Circuit Court ntawm kev txaus siab. Kev nkag siab txog ntau yam ntawm cov txiaj ntsig ua haujlwm tau yog qhov tseem ceeb vim tias qhov inductance tsis tshua muaj nyob rau tag nrho cov kev ua haujlwm ntawm lub cuab yeej. Rau ib qho inductor nyob rau hauv ib daim ntawv thov hloov, qhov tso cai ripple tam sim no thiab xav tau cov lus teb hloov pauv yuav hais qhov xav tau inductance. Cov lus qhia dav dav yog kom ripple ntawm 30% lossis tsawg dua ntawm cov khoom tso tawm tam sim no. Yog hais tias tus inductor yuav tsum tau siv nyob rau hauv ib daim ntawv thov lim, nws impedance yuav tsum siab txaus kom attenuate lub hom phiaj suab nrov zaus. Cov cuab yeej tsim qauv thiab qhov sib npaug muaj nyob hauv online los pab tus kws ua haujlwm xaiv qhov tsim nyog inductance qhov tseem ceeb. Inductance feem ntau sib txawv vim siv DC tam sim no, kub, lossis AC tsav theem. Cov yam tseem ceeb no yuav tsum tau muab rau hauv kev txiav txim siab kom cov inductance nyob rau hauv lub hom phiaj.
DCR Dissipates Thaum tshav kub kub thiab txo kev ua haujlwm
Qhov ncaj qha tam sim no tsis kam (DCR) ntawm ib lub coil dissipates tshav kub thiab txo kev ua haujlwm zoo ib yam li txhua tus resistors nrog tam sim no ntws los ntawm lawv thiab qhov hluav taws xob poob thoob plaws lawv. Nws yog ib qho tseem ceeb rau kev txiav txim siab cov hlau cua sov poob. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv DCR qis dua qhov twg ua tau vim tias nws tuaj yeem txo lub zog poob ntawm inductor. Qee zaum hauv DC / DC daim ntawv thov DCR yog siv los ua txoj kev nkag siab tam sim no thiab kev kam rau siab ua qhov tseem ceeb.
Kev ua yuam kev Saturation tam sim no rau ib qho inductor
Qhov ntsuas tam sim no saturation yog hais txog tus nqi ntawm DC tam sim no tus inductor tuaj yeem txhawb nqa ua ntej nws cov txiaj ntsig inductance poob los ntawm ib feem pua ntawm nominal. Cov luam tawm saturation tam sim no rau ib qho inductor tuaj yeem ua yuam kev heev. Qhov feem pua poob tau teev tseg tuaj yeem teem rau 20% lossis 30%, nyob ntawm cov chaw tsim khoom. Cov ntaub ntawv feem ntau muab cov duab qhia qhov nkhaus ntawm qhov inductance hloov li cas nrog rau DC tam sim no. Qhov no yog ib qho tseem ceeb tshaj ntawm cov ntaub ntawv vim hais tias nws qhia tau hais tias yuav ua li cas tshwm sim rau lub inductance rau ib tug ntau yam ntawm load tam sim no, tsis yog tsuas yog nyob rau hauv ib tug taw tes teev nyob rau hauv cov ntaub ntawv.
Thaum tshav kub kub ntsuas tam sim no thiab Efficiency
Cov khoom siv hluav taws xob inductor muab cov ntsuas kub tam sim no, tab sis zoo li cov dej ntws tawm tam sim no, nws tuaj yeem ua yuam kev. Qhov kev ntsuas no piav qhia txog DC tam sim no uas yuav tsum tau ua kom qhov kub thiab txias ntawm inductor los ntawm tus neeg muag khoom tshwj xeeb (feem ntau yog 40 degree). Cov ntaub ntawv xav tias ib qho kev sim teeb tsa tshwj xeeb uas tso cai rau cov nqi hluav taws xob ntau ntawm cov hluav taws xob tawm ntawm lub inductor los ntawm cov terminals. Nws zoo li qhov kev ntsuam xyuas no tsuas yog ua qhov kwv yees rau kev kwv yees qhov ntsuas kub ntawm inductor. Passive lossis nquag ua kom txias txoj kev, PCB kab dav dav, huab cua ntws, thiab qhov sib thooj rau lwm cov khoom tuaj yeem ua rau qhov tseeb inductor kub txawv dua li qhov ntsuas kub tam sim no. Tsis tas li ntawd, rau cov ntawv thov nrog lub siab ripple amplitude, AC poob tsim nyob rau hauv lub cev tseem ceeb thiab windings yuav ua rau qhov kub thiab txias. Nyob rau hauv kev xyaum, yog hais tias tus inductor khiav inexplicably kub rau ib tug tshwj xeeb load tam sim no, tus tsim yuav tsum tau xyuas kom meej tias muaj txaus tshav kub hloov tawm los ntawm lub terminals thiab core lub cev, los yog hais tias lub Circuit Court tsis ua rau ntau dhau AC poob nyob rau hauv lub inductor.
