Taw qhia txog qhov sib txawv ntawm hloov hluav taws xob muab thiab cov khoom siv linear fais fab
1, hais txog kev txhim kho cov tshuab hluav taws xob muab
Kev txhim kho cov kev loj hlob ntawm niaj hnub hluav taws xob tshuab hluav taws xob yog hloov los ntawm cov tshuab hluav taws xob ib txwm muaj, rau cov hluav taws xob hluav taws xob tsawg, uas feem ntau ua rau cov thev naus laus zis high-zaus. Hauv daim ntawv thov lub zog hluav taws xob tshuab thiab ntau lub zog fais fab, hloov hom fais fab khoom siv yog nyob ntawm cov tub ntxhais.
Los ntawm tus kheej oscillating laub-rub transistor ib transformer DC converter kev tswj hwm los ntawm kev txhim kho lub zog hluav taws xob hauv xyoo 1955, uas yog qhov tseem ceeb ntawm kev txhim kho hauv hluav taws xob kev lag luam.
Dab tsi yog hloov hluav taws xob fais fab
Hloov cov khoom siv hluav taws xob yog cov tsiaj ntawv rau hloov voltager fais fab xa khoom, feem ntau xa mus rau AC (hloov kho tam sim no) - DC (cov kev hloov kho tshiab thiab tawm DC voltage. Lub Hwj Chim Hloov Tube sab hauv lub hloov hluav taws xob ua haujlwm nyob rau hauv lub siab-zaus hloov lub xeev, siv zog heev. Lub hwj huam ua tau zoo tuaj yeem ncav cuag 75% mus rau 90%, uas yog ob zaug kom siab li uas muaj cov khoom siv hluav taws xob zoo tib yam.
1. Ua haujlwm ua haujlwm ntawm hloov hom fais fab mov
Hloov chaw hluav taws xob yog ib hom fais fab uas siv cov hluav taws xob niaj hnub no los tswj lub sijhawm hloov pauv ntawm thiab tawm, tswj cov kev tawm tsam ruaj khov. Lub pob hluav taws xob hloov hluav taws xob muaj xws li mem tes dav dav kev ntsuas (PWM) tswj (hlau oxide sumiconductor teb-cuam tshuam temanors).
Hloov hluav taws xob muab cov hluav taws xob muaj plaub feem ntau: Circuit Court, tswj Circuit Court, Kev Tshawb Nrhiav Hluav Taws Xob, thiab Circiliary Circuit Txwv. Hloov chaw fais fab, raws li lub npe qhia, ib lub qhov rooj cia tam sim no kom dhau los ntawm kev hla dhau los ntawm kev hla dhau. Yog li dab tsi yog lub qhov rooj?
Qee tus neeg hloov hluav taws xob siv cov thyristors siv cov thyristors, uas yog siv hluav taws xob hloov pauv mus rau cov khoom siv hluav taws xob hloov mus rau cov khoom siv hluav taws xob hloov kho kom tiav, thiab siv hluav taws xob ntawm cov zis hluav taws xob.
Qhov sib txawv ntawm hloov hom fais fab fais fab mov thiab cov kab fais fab mov
Tsuas yog muab tso, cov kev cai voltage ntawm cov khoom siv hluav taws xob linear tuaj yeem pom tias yog kev hloov kho tus nqi hluav taws xob, thaum hloov hluav taws xob hloov cov hluav taws xob los ntawm kev kho cov zaus ntawm tus tes hloov. Lub caij no, piv nrog cov khoom siv hluav taws xob linear, tus nqi hloov pauv fais fab ua kom muaj zog ntxiv nrog rau ob qho kev loj hlob ntawm ob qho sib txawv.
1. Tus nqi ntawm cov khoom siv fais fab linear yog qhov ua tau zoo tshaj li ntawm lub tshuab hloov hluav taws xob ntawm qee yam tso zis hwj chim taw tes.
Yog li ntawd, nrog kev txhim kho thiab kev tsim kho lub zog hluav taws xob tshuab, hloov hom khoom siv hluav taws xob txuas ntxiv mus thiab ua kom muaj kev tsim kho. Qhov teeb meem raug nqi no tau hloov pauv hom fais fab tuag thev naus laus zis rau qhov chaw tsim hluav taws xob tsawg, muab ntau qhov chaw loj hlob mus hloov hom fais fab.
