Thevenin vs Norton Theorem

Thevenin's theorem thiab Norton's theorem yog ob qho tseem ceeb theorems siv hauv kev lag luam xws li hluav taws xob engineering, hluav taws xob engineering, physics, ntsuas hluav taws xob thiab kev ua qauv hauv Circuit Court. Ob qhov theorems no yog siv los txo cov circuits loj rau qhov yooj yim voltage qhov chaw, tam sim no qhov chaw thiab resistors. Cov kev xav no muaj txiaj ntsig zoo hauv kev suav thiab simulating kev hloov pauv rau cov kab hluav taws xob loj. Hauv tsab xov xwm no, peb yuav tham txog cov kev siv ntawm Thevenin's theorem thiab Norton's theorem, lawv keeb kwm, cov ntsiab lus, qhov zoo sib xws ntawm ob qhov theorems thiab thaum kawg qhov sib txawv ntawm lawv.

Thevenin's Theorem

Ib txoj kev xav yog ib yam uas tau txhais ntawm cov theorems uas tau lees paub yav dhau los thiab axioms. Yog tias qhov tshwm sim deviates los ntawm theorem, nws tuaj yeem yog vim qhov theorem nws tus kheej, lossis theorems thiab axioms uas tau siv los tsim lub theorem tsis raug. Thevenin's theorem rau cov kab hluav taws xob kab hluav taws xob hais tias txhua qhov chaw hluav taws xob, qhov chaw tam sim no thiab cov resistors tuaj yeem raug txo mus rau qhov sib npaug ntawm qhov hluav taws xob thiab qhov hluav taws xob txuas nrog hauv cov khoom siv hluav taws xob. Txawm hais tias nws yog lub npe hu ua Thevenin's theorem, nws tau pom thawj zaug los ntawm Hermann von Helmholtz, tus kws tshawb fawb German. Nws tau pom thawj zaug hauv xyoo 1853. Tom qab ntawd, tus kws tshaj xov tooj Fab Kis Fab Kis Leon Charles Thevenin rov tshawb pom nws nyob rau xyoo 1883. Qhov no yog ib qho txiaj ntsig zoo heev hauv kev xav hauv Circuit Court. Nws kuj tseem tuaj yeem siv rau lwm lub voj voog tam sim no los ntawm kev siv impedance es tsis txhob ua haujlwm. Thevenin's sib npaug Circuit Court feem ntau yog xam rau qhov qhib Circuit Court. Tom qab ntawd qhov tshwm sim yog siv los ua qauv thiab simulate yuav ua li cas lub Circuit Court yuav coj li cas thaum sib txawv Cheebtsam yog siv los kaw txoj kev Circuit Court. Qhov kev xav no yog qhov muaj txiaj ntsig zoo vim yog kev hloov pauv ntawm lub neej tiag tiag rau cov khoom siv zoo tagnrho. Cov khoom ntawm cov khoom zoo tagnrho no kuj yooj yim los xam.

Norton's Theorem

Norton's theorem kuj yog rau cov kab sib txuas. Norton's theorem hais tias txhua tus naj npawb ntawm cov khoom siv hluav taws xob, cov peev txheej tam sim no thiab cov resistors muaj ob qhov qhib kawg tuaj yeem ua kom yooj yim rau hauv qhov zoo tshaj plaws tam sim no thiab cov resistor txuas nrog tib lub hauv paus. Qhov theorem no tseem tuaj yeem siv rau lwm qhov tam sim no los ntawm kev siv impedance es tsis txhob ua haujlwm. Norton's theorem tau tshawb pom cais los ntawm ob tus neeg. Lawv yog Hans Ferdinand Mayer thiab Edward Lawry Norton. Yog li ntawd, Norton's theorem kuj tseem hu ua Norton-Mayer theorem hauv qee qhov chaw hauv Tebchaws Europe. Qhov no theorem kuj tseem muaj txiaj ntsig zoo thaum nws los txog rau kev simulation Circuit Court. Norton qhov kev tawm tsam kuj yog sib npaug rau Thevenin qhov kev tawm tsam. Norton txoj cai tau tshawb pom ntau dua li Thevenin txoj cai hauv xyoo 1926.

Qhov txawv ntawm Thevenin thiab Norton theorems yog dab tsi?

– Norton's theorem siv qhov tam sim no, whereas Thevenin's theorem siv qhov hluav taws xob.

– Thevenin's theorem siv cov resistor nyob rau hauv series, thaum Norton lub theorem siv cov resister teeb nyob rau hauv parallel nrog lub hauv paus.

– Norton's theorem yog qhov ua tau los ntawm Thevenin's theorem.

– Norton qhov kev tawm tsam thiab Thevenin qhov kev tawm tsam yog sib npaug hauv qhov loj.

– Norton qhov sib npaug Circuit Court thiab Thevenin qhov sib npaug sib npaug tuaj yeem hloov pauv tau yooj yim.
