Txoj cai tsom xam ntawm series tsis zoo tawm tswv yim tswj fais fab mov
Daim duab hluav taws xob ntawm cov lus tawm tswv yim tsis zoo voltage stabilizing Circuit Court, qhov twg T1 yog qhov hloov pauv hloov pauv, D1 thiab R2 tsim cov kev siv hluav taws xob, T2 yog qhov sib piv amplifier, R3-R5 tsim cov qauv ntsuas hluav taws xob, thiab R6 yog cov khoom thauj. . Piv txwv tias yog vim li cas cov zis hluav taws xob UO txo qis, T2 lub hauv paus voltage (UT2) O txo qis los ntawm cov qauv ntsuas hluav taws xob los ntawm R3 txog R5. Txij li thaum T2 emitter voltage (UT2) E yog tswj los ntawm qhov voltage stabilizing tus nqi ntawm tus regulator D1, T2 emitter junction voltage (UT2) BE yuav txo, ua rau txo qis hauv T2 puag tam sim no (IT2) B, txo T2. emitter tam sim no (IT2) E, thiab nce hauv T2 transistor voltage poob (UT2) CE, Ua rau muaj kev nce hauv emitter voltage (UT2) C, piv txwv li kho lub hauv paus voltage (UT1) B ntawm transistor T1 yuav nce, thaum lub voltage poob. (UT1) CE ntawm transistor T1 yuav txo qis, ua rau ntau input voltage UI yuav tsum tau siv rau lub load, ua rau ib tug nce nyob rau hauv cov zis voltage UO. Txoj kev hloov kho no tuaj yeem sawv cev los ntawm kev hloov pauv hauv qab no:
UO ↓ → (UT2) O ↓ → UD1 tas li → (UT2) BE ↓ → (IT2) B ↓ → (IT2) E ↓ → (UT2) CE ↑
→ (UT2) C ↑ → (UT1) B ↑ → (UT1) CE ↓ → UO ↑
Thaum cov zis hluav taws xob nce ntxiv, tag nrho cov txheej txheem ntawm kev hloov pauv yog qhov sib txawv ntawm qhov saum toj no, yog li peb yuav tsis rov ua nws ntawm no, tab sis tsuas yog siv daim duab hauv qab no los sawv cev rau nws:
UO ↑ → (UT2) O ↑ → UD1 tas li → (UT2) BE ↑ → (IT2) B ↑ → (IT2) E ↑ → (UT2) CE ↓
(UT2) C ↓ → (UT1) B ↓ → (UT1) CE ↑ → UO ↓
Zoo ib yam li cov txheej txheem yooj yim tswj hwm lub zog, thaum lwm yam kev mob xws li input voltage UI lossis load tshwm sim, nws yuav ua rau muaj kev hloov pauv hauv cov zis hluav taws xob UO. Cov txheej txheem soj ntsuam saum toj no tuaj yeem siv thaum kawg los piav qhia nws txoj hauv kev ua haujlwm.
Nyob rau hauv tag nrho cov voltage stabilization tswj txheej txheem ntawm series tsis zoo tswv yim fais fab mov, vim hais tias ntawm qhov sib ntxiv ntawm ib tug sib piv amplification Circuit Court T2, qhov kev hloov nyob rau hauv cov zis voltage UO yog amplified los ntawm T2 ua ntej tswj thiab kho lub hauv paus ntawm transistor T1, uas txhim khu lub voltage. stabilization kev ua tau zoo ntawm Circuit Court. T2 Qhov loj dua tus nqi, qhov zoo dua qhov kev ruaj ntseg ntawm cov zis voltage.
