Linear Power Principles vs Switching Power Supplies
Linear fais fab mov (Liner fais fab mov) yog thawj AC lub zog los ntawm kev hloov pauv kom txo qhov voltage amplitude, thiab tom qab ntawd kho los ntawm rectifier Circuit Court rectifier, kom tau txais cov mem tes DC, thiab tom qab ntawd lim kom tau txais DC voltage nrog me me ripple voltage. . Yuav kom ua tiav qhov siab precision DC voltage, nws yuav tsum tau tswj los ntawm qhov hluav taws xob tswj hluav taws xob.
Linear fais fab mov vs. switching fais fab mov
Nws yog hais txog lub raj siv rau kev tswj hwm qhov hluav taws xob uas ua haujlwm hauv thaj chaw saturation thiab txiav tawm, piv txwv li, lub xeev hloov.
Feem ntau, cov zis voltage yog coj mus kuaj thiab tom qab ntawd muab tso rau hauv qhov sib piv voltage amplifier nrog rau qhov siv voltage, thiab cov zis ntawm no voltage amplifier yog siv raws li cov tswv yim ntawm voltage regulator, uas yog siv los tswj lub regulator kom lub junction voltage hloov. Nrog rau kev hloov pauv ntawm cov tswv yim, txhawm rau kho qhov tso zis hluav taws xob, tab sis lub zog hloov hluav taws xob yog siv los hloov cov zis hluav taws xob los ntawm kev hloov lub sijhawm rau thiab tawm ntawm lub regulator, piv txwv li, lub voj voog lub luag haujlwm!
Los ntawm nws cov yam ntxwv tseem ceeb: linear fais fab mov thev naus laus zis yog qhov paub tab, cov nqi tsim khoom qis, tuaj yeem ua tiav qib siab ntawm kev ruaj ntseg, ripple kuj tseem me me, thiab tsis muaj kev hloov hluav taws xob muaj kev cuam tshuam thiab suab nrov, tab sis nws qhov ntim cuam tshuam rau lub zog hloov. mov, kuj loj, thiab cov input voltage ntau yuav tsum muaj siab; thiab switching fais fab mov thiab qhov opposite.
