【正文】 RACT Dc voltage stabilizer by general power transformer, rectifier filter circuit voltage circuit and posed. The high alternating current transformer to need low voltage ac. The alternating current to direct current rectifier. After the filter, regulators and unstable dc voltage into stable dc voltage output. This design main series type dc voltage circuit, through the 220 V, 50 HZ ac voltage power transformer after the buck, through the bridge rectifier VD1VD4 rectifier to dc again by filter capacitance smooth dc, reduce dc lines wavelet coefficients. Finally, the voltage regulator, will output voltage stability in 6V ~ 15 V adjustable voltage. Keywords: transformer。 Rectification。 Multisim software 目 錄 第 1 章 緒論 .................................................................................................................. 1 引言 ..................................................................................................................... 1 概述 ..................................................................................................................... 1 直流穩(wěn)壓電源的應(yīng)用 ......................................................................................... 2 第 2 章 穩(wěn)壓電源的工作原理及性能指標 .......................................................... 3 整體電路框圖 ..................................................................................................... 3 設(shè)計的要求 ......................................................................................................... 3 第 3 章 電路各部分元件的分析 ............................................................................ 4 電源變壓器 ......................................................................................................... 4 變壓器的結(jié)構(gòu) .......................................................................................... 4 變壓器的原理 .......................................................................................... 4 變壓器的變壓比 ...................................................................................... 4 整流電路 ............................................................................................................. 5 半波整流電路 .......................................................................................... 5 全波整流電路 .......................................................................................... 7 橋式整流電路 .......................................................................................... 8 濾波電路 ........................................................................................................... 10 電容濾波電路 ........................................................................................ 10 電感濾波電路 ......................................................................................... 12 倒 L 型濾波電路 ................................................................................... 13 ? 型濾波電路 ......................................................................................... 13 穩(wěn)壓電路 ........................................................................................................... 14 電路組成和穩(wěn)壓原理 ............................................................................ 14 輸出電壓及調(diào)整范圍 ............................................................................ 15 電路所有元件選擇 ........................................................................................... 16 元件清單 ........................................................................................................... 17 第 4 章 電路仿真過程 ............................................................................................. 18 仿真所用的軟件 ................................
