Ua hauj lwm hauv paus ntsiab lus ntawm kev tswj voltage ntawm series tswj fais fab mov
Piv txwv tias qhov tso zis hluav taws xob UO txo qis rau qee qhov laj thawj, uas yog, qhov hluav taws xob emitter (UT1) E ntawm T1 txo, thiab txij li UD1 tseem tsis hloov pauv, emitter junction voltage (UT1) BE ntawm T1 nce, ua rau lub hauv paus tam sim no ntawm T1 ( IT1) B Raws li qhov tshwm sim, T1 emitter tam sim no (IT1) E yog amplified los ntawm lub sij hawm thiab nce. Raws li cov yam ntxwv load ntawm lub transistor, lub sij hawm no, T1 yog tag nrho tig rau. Lub raj hluav taws xob poob (UT1) CE yuav txo qis sai, thiab cov khoom siv hluav taws xob UI yuav ntau ntxiv rau qhov thauj khoom, UO tau txais kev ceev ceev. Txoj kev hloov kho no tuaj yeem sawv cev los ntawm daim duab hloov pauv hauv qab no:
UO↓ →(UT1)E↓ →UD1 Constant →(UT1)BE↑→(IT1)B↑→(IT1)E↑→(UT1)CE↓ →UO↑
Thaum cov zis voltage nce, tag nrho cov txheej txheem kev soj ntsuam yog qhov sib txawv ntawm qhov kev hloov pauv ntawm cov txheej txheem saum toj no, yog li peb yuav tsis rov hais dua ntawm no, tab sis tsuas yog qhia nws nrog cov kab lus hloov pauv hauv qab no:
UO↑ →(UT1)E↑ →UD1 Constant →(UT1)BE↓ →(IT1)B↓ →(IT1)E↓→(UT1)CE↑ →UO↓
Ntawm no peb tsuas yog txheeb xyuas lub hauv paus ntsiab lus ua haujlwm ntawm kev tswj hluav taws xob thaum cov zis hluav taws xob UO txo qis. Qhov tseeb, lub hauv paus ntsiab lus ua haujlwm ntawm kev tswj hluav taws xob hauv lwm qhov xwm txheej xws li kev txo qis ntawm cov input voltage UI zoo ib yam li qhov no. Thaum kawg, nws tau xav txog qhov txo qis ntawm cov zis hluav taws xob UO, yog li lub hauv paus ntsiab lus ua haujlwm zoo ib yam.
Nws tuaj yeem pom los ntawm lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub voj voog uas muaj ob lub ntsiab lus tseem ceeb rau kev tswj hluav taws xob: ib qho yog tias qhov ntsuas hluav taws xob voltage UD1 ntawm qhov hluav taws xob tswj lub raj D1 yuav tsum nyob ruaj khov; Lwm qhov yog tias lub raj regulator T1 yuav tsum ua haujlwm hauv thaj chaw amplification thiab muaj cov yam ntxwv ua haujlwm zoo.
