Cov yam ntxwv tseem ceeb ntawm inductance muaj xws li: inductance, precision, DC tsis kam, kub nce tam sim no, saturation tam sim no, inductive reactance, zoo tshaj plaws, faib capacitance, tus kheej-resonant zaus, kev khiav hauj lwm zaus.
Inductance:
Qhov loj ntawm inductance tsuas yog nyob ntawm tus naj npawb ntawm cov coils, txoj kev winding, seb puas muaj cov tub ntxhais sib nqus thiab cov khoom siv ntawm cov tub ntxhais sib nqus. Feem ntau, qhov ntau ntawm cov coils, qhov ntau dua qhov inductance; Lub inductance ntawm lub kauj nrog ib tug sib nqus core yog loj dua li ntawm ib tug coil yam tsis muaj ib tug sib nqus core. Qhov siab dua cov tub ntxhais permeability ntawm lub kauj, qhov inductance ntau dua.
Qhov twg:
Lyog qhov inductance ntawm lub kauj, H (Henry);
μyog qhov permeability ntawm cov tub ntxhais kem, H / m;
Nyog tag nrho cov lem ntawm lub kauj;
Syog qhov chaw hla ntu ntawm lub kauj, m2;
yog lub longitudinal ntev ntawm lub kauj, m.
Qhov tseeb
Qhov sib txawv ntawm tus nqi tiag tiag ntawm inductance thiab tus nqi nominal, feem ntau qhia raws li feem pua. Feem ntau, qhov tseeb ntawm laminated inductors thiab lub zog inductors yog siab, feem ntau yog li 1%-10%, thaum lub nplhaib sib nqus hom inductors yog ib nrab siab txog 30%-50%.
DC tsis kam
Kev ua haujlwm ntawm inductor coil nyob rau hauv DC, nyob rau hauv inductor tsim, qhov me me ntawm DC tsis kam, qhov zoo dua, chav ntsuas ntawm ohms, feem ntau yog cim nrog nws cov nqi siab tshaj.
Kub nce tam sim no
Kub nce tam sim no hais txog qhov kub siab tshaj plaws ntawm qhov inductor ntawm qhov siab tshaj plaws nyob rau hauv qhov ntsuas kub, thiab qhov kub siab tshaj ntawm 40 degrees feem ntau yog siv los txheeb xyuas qhov kub nce tam sim no hauv kev ua haujlwm tiag tiag. Qhov kub nce tam sim no muaj feem xyuam rau DC tsis kam, thiab tseem ua rau lub peev xwm ntawm cov cua sov ntawm lub inductor coil, yog li qhov kub nce tam sim no tuaj yeem nce los ntawm kev txo cov DC tsis kam lossis nce qhov inductor loj.
Saturation tam sim no
Ntxiv ib qho nyiaj tshwj xeeb ntawm DC bias tam sim no rau inductor, kom tus nqi inductance ntawm inductor txo qis, piv rau tus nqi inductance yam tsis ntxiv tam sim no los ntawm 10% mus rau 30%, qhov DC bias tam sim no hu ua saturation tam sim no ntawm inductor.
Inductive kuj
Qhov loj ntawm inductor coil thaiv cov AC tam sim no hu ua inductive reactance XL, thiab chav tsev yog ohms. Nws muaj feem xyuam rau qhov inductance L thiab AC zaus f: XL=2πfL.
Yam khoom zoo
Qhov zoo tshaj plaws Q yog lub cev muaj nuj nqis uas sawv cev rau qhov zoo ntawm cov kauj, Q yog qhov piv ntawm inductive resistance XL rau nws qhov sib npaug, uas yog: Q=XL/R. Qhov siab dua Q tus nqi ntawm lub kauj, qhov tsawg dua qhov poob. Q tus nqi ntawm cov kauj yog cuam tshuam nrog DC tsis kam ntawm cov xaim, qhov dielectric poob ntawm lub cev pob txha, qhov poob los ntawm cov ntaub thaiv npog lossis cov tub ntxhais hlau, thiab kev cuam tshuam ntawm cov tawv nqaij ntau zaus.
Faib cov capacitors
Lub capacitance ntawm lem ntawm lub kauj thiab nruab nrab ntawm lub kauj thiab cov ntaub thaiv npog yog hu ua faib capacitance. Lub hav zoov ntawm kev faib capacitance txo qis Q tus nqi ntawm lub kauj thiab kev ruaj ntseg yuav ua rau tsis zoo, yog li qhov me me ntawm cov khoom xa tawm ntawm lub kauj, qhov zoo dua. Qhov faib capacitance tuaj yeem raug txo los ntawm segmental winding.
Self-resonant zaus
Vim tias muaj cov kab hluav taws xob faib tawm Cp, ib qho hluav taws xob resonant tau tsim ua ke nrog L, nws qhov zaus resonant yog tus kheej-resonant zaus ntawm inductor. Ua ntej tus kheej-resonant zaus, qhov impedance ntawm inductor nce nrog qhov nce ntawm zaus. Tom qab tus kheej-resonant zaus, qhov impedance ntawm inductor txo qis raws li qhov zaus nce, thiab lub capacitance tau nthuav tawm.
Qhov twg:
Rpyog qhov sib npaug ntawm kev sib nqus core poob
Rsyog qhov sib npaug ntawm cov hlau tsis muaj zog
Cpyog qhov sib npaug capacitance ntawm electrodes
Lyog qhov tseeb inductance tus nqi ntawm inductor
Ua haujlwm zaus
Hauv kev siv cov tswv yim, qhov kev xeem zaus feem ntau yog siv, uas yog qhov tseem ceeb ntawm kev ua haujlwm zaus lossis ze tus nqi ntawm cov neeg siv khoom. Qhov ntsuas zaus yog siv los ntsuas tus nqi inductance lossis qhov zaus ntawm Q tus nqi ntawm inductor. Feem ntau siv cov zaus xeem muaj xws li: 1KHz, 10KHz, 50KHz, 100KHz, 1MHz, 10MHz, 50MHz, thiab lwm yam.
