Lub tshuab hluav taws xob sib nqus yog cov khoom siv hluav taws xob zoo li qub uas tsim los tswj tus nqi ntawm qhov hloov pauv tam sim no nrog qhov tsis tu ncua. Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm xws li ib tug ntaus ntawv yog raws li nyob rau hauv lub nonlinear yam ntxwv ntawm ib tug magnetized magnetic Circuit Court. Lub tshuab hluav taws xob sib nqus feem ntau yog siv los ntawm kev tswj tsis siv neeg lub tshuab hluav taws xob (ob qho tib si synchronous thiab asynchronous) uas ua haujlwm ntawm alternating tam sim no.

Cov cuab yeej ntawm cov cuab yeej zoo li no yooj yim heev. Lub magnetic amplifier muaj ib qho kev ua haujlwm winding, uas nyob rau ntawm nws cov pas nrig heev. Nws yog tsim los ntawm ob lub coils txuas nrog hauv series. Kev tswj winding nrog ntau tus lem yog muab tso rau ntawm tus pas nrig nruab nrab. Yog tias tam sim no tsis tau muab rau nws, tab sis dhau los ntawm kev ua haujlwm winding, uas tau txuas nrog hauv cov khoom thauj, ces cov hlau nplaum hluav taws xob yuav tsis saturated nrog cov khoom siv hloov hluav taws xob vim qhov me me.tus lej tig. Nyob rau hauv cov ntaub ntawv no, tag nrho cov voltage yuav poob rau ntawm qhov ua hauj lwm winding (nyob rau hauv cov ntaub ntawv no nws yuav reactive). Hauv qhov no, lub zog qis yuav raug faib rau lub nra.

Cov khoom sib nqus ntawm cov cuab yeej xws li lub tshuab hluav taws xob sib nqus yog saturated vim qhov tseeb tias tam sim no dhau los ntawm kev tswj winding. Vim muaj coob tus lem ntawm nws, txawm ib tug me me tam sim no tus nqi yog txaus. Raws li ib tug tshwm sim ntawm xws li ib tug txheej txheem, lub reactive tivthaiv ntawm lub kuj ntawm lub ua hauj lwm winding yuav sharply txo, thiab tus nqi ntawm cov tam sim no nyob rau hauv lub tswj Circuit Court yuav sai heev. Yog li, nrog cov cim me me ntawm kev tswj winding, lub zog loj tuaj yeem tswj tau.

Hauv qhov yooj yim tshaj plaws, cov cuab yeej xws li lub tshuab hluav taws xob sib nqus yog ib qho inductance uas tswj los ntawm qhov tam sim no ncaj qha. Rau kev tswj kom zoo, lub inductor yuav tsum tau txuas nrog cov khoom siv hauv AC Circuit Court.

Rau qhov tseem ceeb ntawm inductance loj, tus nqi ntawm cov tam sim no nyob rau hauv series Circuit Court thiab lub load yog me me. Nrog me me inductance nyob rau hauv ib tug series Circuit Court, tam sim no yuav loj. Nyob rau hauv lub load, feem, nws tus nqi kuj yuav nce nyob rau hauv feem rau qhov txo nyob rau hauv inductance. Muaj ntau qhov kev txhim kho uas siv cov cuab yeej xws li lub tshuab hluav taws xob sib nqus siv xws li, piv txwv li, tsis sib cuag relay (rau kev hloov pauv tsis sib cuag), rau ob npaug ntawm tus nqi zaus, rau kev ruaj khov ntawm qhov hluav taws xob hauv Circuit Court, rau kev hloov pauv. high-frequencyCov teeb liab tsawg zaus, raws li cov cuab yeej xws li lub tshuab hluav taws xob tam sim no, rau kev tswj cov khoom siv hluav taws xob, thiab lwm yam.

Txawm hais tias tsis ntev los no cov khoom siv sib nqus sib nqus tau hloov pauv los ntawm cov khoom siv semiconductor hauv qee thaj chaw ntawm lawv daim ntawv thov, hauv thaj chaw xws li kev tswj hluav taws xob hauv cov khoom siv, tswj cov teeb pom kev zoo ntawm cov tsev hais plaub thiab xinesmas, thiab hauv kev tswj cov tshuab hluav taws xob, cov hlau nplaum. amplifier tsis muaj kev sib tw rau hnub no. hnub.
