Tus txiv neej niaj hnub yog ib puag ncig los ntawm cov khoom siv hluav taws xob ntau, ob qho tib si hauv tsev thiab kev lag luam. Nws yog ib qho nyuaj rau xav txog peb lub neej yam tsis muaj cov khoom siv hluav taws xob, lawv ntsiag to nkag hauv tsev. Txawm nyob rau hauv peb lub hnab ris yeej ib txwm muaj ob peb ntawm cov khoom siv no. Tag nrho cov cuab yeej no rau nws txoj haujlwm ruaj khov yuav tsum muaj hluav taws xob tsis cuam tshuam. Tom qab tag nrho, surges nyob rau hauv lub mains voltage thiab tam sim no feem ntau ua rau tsis ua hauj lwm ntawm li.
Txhawm rau kom muaj lub zog zoo rau cov khoom siv, nws yog qhov zoo tshaj plaws los siv lub stabilizer tam sim no. Nws yuav tuaj yeem them rov qab rau kev hloov pauv hauv network thiab txuas ntxiv lub neej kev pabcuam.
Lub stabilizer tam sim no yog ib qho khoom siv uas tswj xyuas qhov tam sim no ntawm tus neeg siv khoom nrog qhov raug muab. Nws them nyiaj rau tam sim no zaus surges nyob rau hauv lub network, hloov nyob rau hauv load zog thiab ambient kub. Piv txwv li, ua kom lub zog rub los ntawm ib lub cuab yeej yuav hloov qhov kev kos tam sim no, ua rau muaj qhov hluav taws xob poob thoob plaws qhov chaw tiv thaiv nrog rau cov xaim hluav taws xob. Qhov ntau dua tus nqi ntawm lub internalkuj, qhov ntau qhov voltage yuav hloov nrog nce load tam sim no.
Cov nyiaj them rov qab tam sim no yog lub cuab yeej kho tus kheej uas muaj cov lus tawm tswv yim tsis zoo. Stabilization yog ua tiav raws li qhov tshwm sim ntawm kev hloov pauv ntawm qhov kev tswj hwm lub hauv paus, thaum muaj kev tawm tswv yim mem tes ua rau nws. Qhov no parameter yog hu ua qhov tso zis tam sim no muaj nuj nqi. Raws li hom kev tswj hwm, cov nyiaj them rov qab tam sim no stabilizers yog: nruam, pulsed thiab sib xyaw.
Main parameters:
1. Input voltage stabilization yam:
K st.t=(∆U in /∆IH) (IH /U in), qhov twg
In , ∆In – tus nqi tam sim no thiab nce tus nqi tam sim no hauv qhov load.
K-factor st.t calculated at tas li load resistance.
2. Tus nqi ntawm qhov stabilization coefficient nyob rau hauv qhov kev tshwm sim ntawm kev hloov nyob rau hauv tsis kam:
KRH=(∆R n/ R n)(IH/∆IH)=ri / RH where
RH, ∆R н - tsis kam thiab nce ntxiv ntawm kev ua haujlwm;
gi - sab hauv tus nqi ntawm tus stabilizer.
KRH coefficient yog xam nrog qhov hluav taws xob tsis tu ncua.
3. Tus nqi ntawm qhov kub thiab txias coefficient ntawm stabilizer: γ=∆I n /∆t environment
Rau lub zog tsis muaj zogstabilizers hais txog qhov ua tau zoo: η=P out/P in.
Cia peb xav txog qee lub tswv yim ntawm stabilizers.
Kev dav heev yog qhov stabilizer tam sim no ntawm lub teb-tshuaj cuam tshuam transistor, nrog lub rooj vag luv thiab qhov chaw, raws li Uzi=0. Lub transistor nyob rau hauv no Circuit Court yog txuas nrog nyob rau hauv series nrog lub load kuj. Cov ntsiab lus ntawm kev sib tshuam ntawm kev thauj khoom ncaj qha nrog cov khoom tso tawm ntawm lub transistor yuav txiav txim siab tus nqi ntawm qhov tam sim no ntawm qhov qis tshaj thiab siab tshaj tus nqi ntawm cov input voltage. Thaum siv xws li ib tug Circuit Court, lub load tam sim no hloov me ntsis nrog ib tug tseem ceeb hloov nyob rau hauv lub input voltage.
Hloov cov stabilizer tam sim no muaj nws qhov txawv ntawm kev ua haujlwm ntawm transistor-regulator hauv lub xeev hloov. Qhov no tso cai rau koj kom ua tau zoo ntawm cov cuab yeej. Ib qho kev hloov pauv tam sim no stabilizer yog ib hom kev hloov pauv ib zaug uas tau them los ntawm lub voj voog tawm tswv yim tsis zoo. Xws li cov khoom siv, nyob ntawm qhov kev siv ntawm lub hwj chim, tuaj yeem muab faib ua ob hom: nrog rau kev sib txuas ntawm lub choke thiab transistor; nrog rau kev sib txuas ntawm lub choke thiab ib qho kev sib txuas ntawm kev tswj hwm transistor.
