Stabilized fais fab mov: Zoo thiab tsis zoo

Nrog rau cov invention ib lub sijhawm zoo zener stabilized AC voltage. Nws yog tsim nyog rau tej kev hauj lwm ntawm ntau tsev neeg pab kiag li lawm. Niaj hnub nimno stabilized hwj chim qhov twg los muaj zoo tso zis yam ntxwv thiab yog siv nyob rau hauv yuav luag tag nrho cov hluav taws xob circuits. Nws muaj peev xwm yuav nrhiav tau nyob rau hauv lub recorders, TV, chargers, computers, thiab lwm yam

Los ntawm zoo khoom noj khoom haus schemes txawv heev. Nws yog ib feem ntawm lub stability ntawm tag nrho cov ntaus ntawv. Nyob rau hauv tas li ntawd mus khoom vaj khoom tsev, stabilized fais fab mov yog dav siv nyob rau hauv qhov. Nrog kev pab los ntawm hluav taws xob circuits ua zaub mov, uas yog muab kev koom tes nyob rau hauv tus txheej txheem tswj. Rau DC voltage qhov chaw zoo tshwj xeeb uas yuav tsum tau, vim hais tias ntawm lawv cov chaw ua hauj lwm nyob rau hauv lub qub hauj lwm ntawm tag nrho cov ntau lawm kab.

Feem ntau ib tug alternating voltage stabilizers yog muaj parametric stabilizer, uas yog ib tug dog dig voltage divider, ib txhais caj npab uas muaj xws li ib tug zener diode. Lub tswvyim yog li ntawd yooj yooj yim thiab txhim khu kev qha nyob rau hauv kev siv, hais tias nws siv nyob rau hauv electronics tau ua de rigueur nyob rau hauv lub tsim ntawm ntau yam pab kiag li lawm.

Lub nonlinear cov yam ntxwv ntawm cov zener diode tso cai rau lub tsim ntawm ib tug tswj voltage uas yog txhab khoom mus rau transistor amplifier theem hauv paus. Thaum cov qhov tso zis li no feem ntau yog muab tso rau electrolytic capacitors. Lawv ua hauj lwm - kom rectify ib stabilized voltage. Xws li ib tug tswvyim muaj ib tug heev zoo kev ua tau zoo, lub ripple ntawm cov qhov tso zis tsis pub tshaj ib feem pua. Nws yuav tsum tau ntaus nqi rau qhov uas tsis muaj theem ntawm faib suab nrov raws li txoj hauj lwm zoo. Tab sis xws li ib tug ruaj khov hwj chim qhov twg los nws muaj nws cov drawbacks. Qhov no tsis tshua muaj efficiency thiab loj qhov ntev, vim nws yog siv ib lub hwj chim cia transformer.

Attempts mus kho cov drawbacks coj mus rau txoj kev loj hlob ntawm pab kiag li lawm nyob rau hauv uas tus mem tes transformation hauv paus ntsiab lus. Kev ua hauj lwm ntawm tej qhov chaw yog raws li nyob rau rectification ntawm lub AC voltage thiab hloov nws mus rau hauv ib tug mem tes zaus mus txog 1000 Hz thiab saum toj no. Nws transformation yuav tsum tau siv me me transformers. Qhov no tau coj mus rau kev txiav nyob rau hauv loj thiab nce rau hauv efficiency ntawm tus dais.

Tom ntej no, lub voltage yog stabilized thiab smoothed los ntawm capacitors. Xws li ib tug stabilized hwj chim qhov twg los muaj ib tug high efficiency thiab me me qhov ntev. Tiam sis nws muaj ib theem siab ntawm cov suab nrov nyob rau hauv cov zis. Lawv siv yog advisable nyob rau hauv tsev neeg daim ntaub ntawv nyob qhov twg ib tug parameter xws li ib tug loj, yog ib qho tseem ceeb. Switching hwj huam muaj pov thawj rau lawv tus kheej thiab yog siv nyob rau hauv TV, computers, laptops, thiab lwm yam

Rau cov koom haum ntawm lub tsev lab yog pab tau mus yuav los yog ua rau koj tus kheej ib tug stabilized fais fab mov. Nws yuav pab tau kom teem schemes thiab thawj muab cov kev tsim nyog voltage. Cov blocks yog lug siv nyob rau hauv zus tau tej cov chaw soj nstuam, lawv yuav siv tau los kho lossis tsim tshiab electronic pab kiag li lawm.
