Lub voltage regulator. Thiab yog dab tsi koj yuav mus tom ntej?

Lub voltage regulator. Thiab yog dab tsi koj yuav mus tom ntej? Tej zaum ib tug ntawm cov thawj txoj kev sib tw muag los ntawm tej xov tooj cua amateur los yog engineer circuitry, yog qhov teeb meem ntawm lub tshuab hluav taws xob ntaus ntawv ntawm cov voltage. Yog xav tau ib yam voltage siv lub hwj huam mov los yog voltage regulator.

Nyob rau hauv lub feem ntau nqe lus dav dav, ib tug yuav hais tias tus ntaus ntawv hloov tus nqi ntawm voltage ntawm lub hloov lub teeb liab uas nkag mus rau los yog raug rau ntawm lwm yam yog hu ua ib tug voltage regulator.

Nws yuav tsum tau muab sau tseg tias voltage cai yog xws li ib tug kev lag luam uas yog tau nyob rau hauv ntau theem thaum lub sij hawm lub lag luam ntawm hluav taws xob. Nws yog ua tau kom hloov cov thawj mov voltage yuav hloov lub qhov voltage network regulating tus voltage nyob rau hauv tag nrho cov mob, lub hom phiaj ntawm tag nrho cov ua hauj lwm yuav tsum yog ib - hloov ib tug nqi kom tau lwm, kom ntseeg tau tseeb lag luam ntawm lub ntaus ntawv.

Lub hauv paus ntsiab lus, uas yog siv nyob rau hauv lawv cov chaw ua hauj lwm lub voltage regulator kuj yuav sib txawv heev, raws li zoo raws li lub sij hawm teem tseg ntawm xws kiag li lawm. Lawv muaj peev xwm ua raws li:

- voltage stabilizers, muab tsim nyog operating voltage mov los yog tag nrho cov Circuit Court ntshav;

- tej zaum yuav lub voltage converters, thiaj li mus hais lus, yuav tau los ntawm ib lwm voltage;

- tej zaum yuav ua raws li qhov chaw ntawm reference los yog tswj voltage, kom ntseeg tau qhov tseeb lag luam ntawm tag nrho cov Circuit Court.

Qhov no yog tsis yog ib tug ua tiav daim ntawv teev cov yam ntxwv thiab daim ntaub ntawv ntawm tej pab kiag li lawm. Yog li ntawd, raws li ib qho piv txwv, ib tug yooj yim voltage regulator - yog autotransformer, los yog LATR, uas hloov cov qhov tso zis voltage los tsuas tig lub pob qhov rooj.

Yog li, peb muaj ib tug network xws li, voltage regulator ntawm cov thawj network, los yog lub AC voltage regulator. Tag nrho cov no yuav tsum yog tib yam.

Lwm cov piv txwv ntawm daim ntawv thov ntawm regulators - xov tooj ntawm tes them. Yeej muaj tseeb, muaj yog twb nyob rau hauv kev siv, li ntawd, yuav hais lus, ib tug muab ob npaug rau voltage hloov dua siab tshiab. Chiv, alternating voltage network yog txo mus rau cov yam nqi, ces tus AC voltage yog tau los ntawm ib tug tas mus li. Xov tooj ntawm tes yog powered los ntawm ib tug rechargeable roj teeb, thiab muaj ib tug tsis tu ncua voltage. Yog li ntawd peb tau tawm ntawm kab voltage ntawm 220V DC voltage 9V (los yog txawm nws yuav siv sij hawm rau cov ntaus ntawv). Yog li, peb muaj, ua tsaug rau lub charger, lub voltage hloov tau siv peb cov thawj txhais.

Tsis muaj tsawg ib qho tseem ceeb daim ntawv thov ntawm voltage regulators yog siv lawv nyob rau hauv nruab ntawm kev cai thiab cov txij nkawm ntawm tus dais khiav hauj lwm hom rau cov neeg tsim nyog. No, raws li ib qho piv txwv, peb yuav xav txog lub voltage regulator nyob rau hauv lub tsheb. Tag nrho cov tsim nyog hluav taws xob hwj chim thaum tsav tsheb lub tsheb ntaus ntawv muab ib tug generator lag luam hom uas nyob ntawm lub engine lag luam thiab tus xov tooj ntawm revolutions ntawm lub yav tas. Raws li to taub los ntawm cov piav generator lag luam hom yog hloov, thiab chaw pib yuav txawv cov voltage generated los ntawm lawv. Ib tug yuav tsum tau ntau dua los yog tsawg qhov voltage mus rau lub electronics. Nws yog ib qhov teeb meem thiab daws tshwj xeeb voltage regulator, sawv ntawm lub tsheb. Principles rau cov kev cai thiab kev hloov ntawm lub voltage regulator yuav ua tau txawv heev, thiab tam sim no uas tsis muaj kev txaus siab rau peb.

Tej zaum koj yuav tsum tau kho cov voltage nyob rau hauv lub hwj chim qhov chaw los yog pab kiag li lawm uas muaj hwj chim noj. Nyob rau hauv cov neeg mob siv hwj chim tswj hais xws li ib tug thyristor thiab ib tug triac. Ntawm no xws triac voltage regulator yog yuav hloov sufficiently loj qhov tseem ceeb ntawm voltage thiab tam sim no.

Xam tias yog voltage regulators tsis npog tag nrho cov muaj peev xwm ntawm cov pab kiag li lawm, tab sis nyob rau hauv txoj kev ntsuam xyuas txoj kev muab ib lub tswv yim dab tsi tus dais no yog, thiab ua li cas nws yog siv.
