Kev tsom xam ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob analog, hloov fais fab khoom siv, thiab cov khoom siv digital fais fab
Nyob rau hauv cov fais fab khoom tsim, qhov yuavtsum tau kawm uantej yog kom nkag siab ntau lub zog hluav taws xob thiab lawv cov kev sib txawv, yog li ntawd peb tuaj yeem xaiv lub hwj chim module.
Kev siv hluav taws xob sim: Kuj pom tias yog hloov hluav taws xob hloov, siv los ntawm cov tub ntxhais hlau txheem thiab coil. Tus naj npawb ntawm lem ntawm coil txiav txim siab lub voltage piv rau ob qho kawg. Lub luag haujlwm ntawm cov hlau core yog los xa cov chaw sib nqus sib nqus. Hauv Suav teb, lub coil loj tsim kev hloov sib nqus sib nraus teb ntawm ib zaus ntawm 50z, uas tau kis mus rau theem theem siab los ntawm cov tub ntxhais hlau. Qhov kev hloov pauv sib nqus no ua rau hluav taws xob voltage nyob rau hauv theem nrab chev, thiab transformer ua tiav voltage hloov.
Qhov tsis zoo ntawm Analog Fais Fab muab khoom: Lub kauj thiab hlau cov tub ntxhais lawv tus kheej, yog li kev ua kom muaj cua sov (poob siab) yog tsawg, feem ntau tsis tshaj 35%. Daim ntawv thov ntawm cov hloov pauv hauv cov khoom siv suab nrov nrov: Cov hluav taws xob muaj zog tshaj tawm kom ua tiav los ntawm kev nce cov neeg siv hluav taws xob ntxiv thiab ntim cov hlau txheem. Nce tus naj npawb ntawm cov lem thiab ntim ntawm cov hlau tseem ceeb yuav ua rau lawv poob. Yog li, transformers rau high - Lub zog amplifiers tshaj plaws yuav tsum tau ua loj heev, uas yuav ua rau muaj kev kub siab thiab muaj zog kub.
Hloov chaw fais fab: ua ntej nkag mus rau tus neeg hloov pauv tam sim no, hloov ua haujlwm ntawm lub transistor tau siv los ua kom ntau li ib txwm 50Hz tam sim no mus rau kaum txhiab HZ. Ntawm xws li ib tug loj heev, qhov zaus ntawm kev sib nqus teb hloov kuj tseem tuaj yeem ua rau kaum txhiab txhiab HZ. Qhov no tuaj yeem txo cov coil tig thiab ntim ntawm cov hlau tseem ceeb kom tau txais tib qho hluav taws xob sib piv. Vim tias qhov kev txo qis ntawm coil hloov thiab cov khoom lag luam hlau, cov poob yog txo qis. Feem ntau, kev ua tau zoo ntawm hloov fais fab kev ncav cuag 90%, thiab lub ntim tuaj yeem ua kom me me nrog cov zis khov kho. Yog li, hloov fais fab fais fab muaj qhov zoo uas analog fais fab muab tsis tau.
