Tam sim no stabilizer: los, hauj lwm tswvyim

Niaj hnub nimno tus txiv neej yog lossi surrounded los ntawm ib tug loj loj tus naj npawb ntawm hluav taws xob khoom, ob qho tib si domestic thiab muaj. Nws yog ib qhov nyuaj rau xav txog tej yam peb lub neej tsis muaj hluav taws xob pab kiag li lawm, lawv ntsiag to nkag mus hauv lub tsev. Txawm nyob rau hauv peb twb muaj yuav yeej ib txwm yog ib tug ob peb xws kiag li lawm. Tag nrho cov no technology rau nws ruaj khov lag luam yuav tsum tau ib tug tas mus mov ntawm hluav taws xob. Tom qab kev sib xeem khiav cov mains voltage thiab tam sim no yog feem ntau qhov ua rau tsis ua hauj lwm ntawm lub ntaus ntawv.

Yuav ua kom zoo mov ntawm kev cov khoom zoo tshaj plaws yog siv ib tug tam sim no stabilizer. Nws yuav tau pab kom txawm peem rau lub network hloov mus hloov los thiab cas sim haum pab lub neej.

tam sim no stabilizer - ib tug ntaus ntawv uas tau koom tes rau cov neeg siv tam sim no nrog ib tug predetermined precision. Nws compensates rau lub zaus ntawm qhov tam sim no surges nyob rau hauv lub network, qhov kev hloov ntawm load lub hwj chim thiab lub ambient kub. Piv txwv li, ua lub hwj chim noj los ntawm lub ntaus ntawv, yuav hloov lub tswv yim tam sim no, yuav ua tau lub voltage nco nyob rau qhov twg los kuj thiab thaiv kuj. Qhov ntau dua tus nqi ntawm cov internal kuj, qhov ntau voltage yuav hloov nrog ua load tam sim no.

Nyiaj Raug Mob Tom tam sim no stabilizer yog ib tug ntaus nrog automatic tswj, uas muaj ib cov saw ntawm tsis zoo lub tswv yim. Stabilization yog tiav los ntawm kev hloov lub ciaj ciam ntawm lub kho neeg, nyob rau hauv cov ntaub ntawv ntawm raug mus rau lub tswv yim mem tes. Qhov no parameter yog hu ua cov kev ua ntawm cov qhov tso zis tam sim no. Ntxawg mean nyiaj tam sim no stabilizers yog: tas mus li, pulsed thiab mixed.

Lub ntsiab tsis:

1. stabilized tau tus nqi ntawm lub tswv yim voltage:

_St.t K = (ΔU _Rin / ΔI _H) * (kuv _H / U _bx), qhov chaw uas

Kuv _n, ΔI _n - tam sim no tus nqi thiab cov increment nqi ntawm cov tam sim no nyob rau hauv lub load.

_St.t coefficient K xam ntawm qhov load kuj.

2. Cov coefficient ntawm stabilization nyob rau hauv cov ntaub ntawv ntawm kuj hloov:

K _{R H} = (ΔR _n / R _n) * (kuv _H / ΔI _H ) = R _kuv / R _{H, wherein}

R _H , ΔR _n - thiab lub increment ntawm cov kuj ntawm lub load kuj;

r _kuv - tus nqi ntawm Internal kuj stabilizer.

Lub coefficient K _{R H} yog xam nrog rau ib tug tas mus li tswv yim voltage.

3. Tus nqi ntawm qhov kub thiab txias coefficient stabilizer: γ = ΔI _n / Δt _env.

Yuav kom lub zog tsis stabilizers koom efficiency: η = P _O / P _Rin.

Xav txog tej schemes stabilizers.

Ib tug heev lug kis stabilizer tam sim no FET, thaum ib tug luv luv-circuited rooj vag thiab qhov chaw, ntsig txog, U = 0 _bonds. Lub transistor nyob rau hauv xws li ib tug Circuit Court kev cob cog rua nyob rau hauv series nrog lub load kuj. Cov kev tshuam cov ntsiab lus nrog rau cov ncaj load tso zis yam ntxwv ntawm cov transistor txiav txim tam sim no muaj nqis nyob rau lub me tshaj thiab qhov loj tshaj plaws nqi ntawm lub tswv yim voltage. Nrog xws li ib tug load tam sim no Circuit Court mas nws txawv me ntsis nrog rau ib tug tseem ceeb variation nyob rau hauv lub tswv yim voltage.

Switching Regulator nws txwm yog tus tam sim no ntawm cov transistor - xws li nyob rau hauv lub switching lub xeev. Qhov no ua rau nws ua tau rau kom cov efficiency ntawm tus dais. Pulsed tam sim no stabilizer yog ib hom ntawm ib lug converter them los ntawm qhov tsis zoo tswv yim voj. Xws li nyob rau qhov kev siv ntawm lub hwj chim tsev yuav tau muab faib mus rau hauv ob hom: ib tug series kev twb kev txuas ntawm ib tug throttle thiab ib tug transistor; nrog ib tug serial kev twb kev txuas thiab thaum uas tig mus inductor regulator transistor kev twb kev txuas.
