Cheebtsam xaiv rau transistor tswj fais fab mov
Cov kauj ruam rau kev xaiv cov khoom nyob rau hauv lub Circuit Court no zoo ib yam li cov silicon voltage regulator raj parallel voltage stabilizing Circuit Court, feem ntau xav txog cov nram qab no yam.
(1) Kev hloov ua ntej tube T1 thiab voltage regulator raj D1
Thaum xaiv lub regulating tube T1, lub ntsiab xav txog yog tias nws rated tam sim no ICM yuav tsum muaj ntau tshaj li qhov tso zis tam sim no IO kom ntseeg tau tias lub regulating raj yuav tsis puas vim yog heev tam sim no thaum lub load yog qhib. Tsis tas li ntawd, txhawm rau xyuas kom meej tias lub raj hloov kho tau zoo, nws tseem yuav tsum tau ua kom tus nqi loj thiab cov xau tam sim no me me. Thaum xaiv qhov voltage regulator raj D1, lub ntsiab kev txiav txim siab yog tias cov sum ntawm nws ruaj khov voltage thiab T1 emitter junction voltage yuav tsum sib npaug zos rau cov zis voltage.
(2) Xaiv qhov input voltage
Txhawm rau kom ntseeg tau tias qhov ua tau zoo ntawm cov khoom siv hluav taws xob tswj hwm, feem ntau yuav tsum tsis txhob teeb tsa siab dhau thiab yuav tsum tsis pub tshaj 2 UI.
(3) Xaiv qhov txwv tam sim no resistor R2
Rau qhov sib npaug voltage stabilizing Circuit Court, tam sim no limiting resistor R2 yog tus yuam sij rau kev ua hauj lwm zoo ntawm tag nrho cov Circuit Court. Qhov loj dua R2 xaiv, qhov zoo dua qhov voltage stabilization nyhuv, tab sis lub hwj chim noj yog loj (vim hais tias lub resistor zog noj P=I2R), thiab cov input voltage yuav tsum tau nce, yog li cov efficiency ntawm lub hwj chim mov. yog tus qis. Rau cov txheej txheem kev suav tshwj xeeb, thov xa mus rau theem thib peb ntawm kev xaiv silicon voltage regulator tube parallel voltage stabilization circuit Cheebtsam.
(4) Txheeb xyuas Circuit Court stability
Kev ruaj ntseg ntawm tag nrho cov Circuit Court yuav tsum tau txiav txim siab raws li qhov yuav tsum tau ua hauv Circuit Court. Yog tias qhov kev ruaj ntseg tsis txaus, koj tuaj yeem nce R1 thiab UI kom tsim nyog, thiab koj tuaj yeem xaiv cov kav dej tswj nrog tus nqi loj dua thiab cov xau me me.
Circuit Court txoj kev tsom xam ntawm transistor tswj fais fab mov
Ib tug parallel tswj fais fab mov siv ib tug composite regulator raj. Qhov sib txawv loj tshaj plaws nyob rau hauv Circuit Court yog tias lub raj regulator tau hloov pauv kom ua raws li cov qauv ntawm lub raj, kom tus nqi loj dua tuaj yeem tau txais thiab ICM loj dua tuaj yeem tau txais. Ib txoj kev zoo sib xws tuaj yeem siv thaum xaiv cov khoom, tab sis txij li qhov tam sim no ntawm lub Circuit Court no kuj loj heev, nws yuav tsum tau muab sau tseg tias ntxiv rau tus nqi kuj, lub hwj chim ntawm tam sim no-txheej resistor R1 kuj yuav tsum tau txiav txim siab thaum xaiv nws. Txhawm rau kom tsis txhob hlawv tawm tam sim no limiting resistor thaum lub load raug txiav.
Qhov zoo thiab qhov tsis zoo ntawm Parallel Stabilized Power Supply
Qhov zoo ntawm parallel tswj fais fab mov:
1. Nws muaj overload tiv thaiv tus kheej muaj nuj nqi, thiab kev kho lub raj yuav tsis puas thaum cov zis yog luv luv.
2 Thaum lub load hloov me me, qhov voltage stabilization kev ua tau zoo kuj zoo.
3. Kev hloov tau zoo rau kev hloov pauv sai sai.
Disadvantages ntawm parallel voltage stabilizing Circuit Court:
1 Qhov kev ua tau zoo yog qhov tsawg, tshwj xeeb tshaj yog thaum lub teeb thauj khoom, yuav luag tag nrho cov hluav taws xob hluav taws xob tau siv nyob rau hauv qhov kev txwv tam sim no thiab cov raj hloov kho.
2 Cov zis hluav taws xob hloov kho ntau yam tsawg heev.
3 Nws tsis yog yooj yim kom ua tiav siab ruaj khov.
