【正文】 ablishment to each module and the interior parameter of system, for example simulation algorithm, electronic device choice and electrical source peaktopeak value and frequency and so on, finally realized simulation that the electric power electronics alternatingcurrent circuit in MATLAB. Simulation result and theoretical analysis result consistent, has confirmed the simulation modelling validity and the accuracy. Finally, this paper summarizes the research results and makes suggestions for further improvement. Keywords: Matlab/Simulink , Simulation, Rectifier circuit, Chopper circuit 3 目 錄 第 1 章 概述 ................................................................................................................... 5 國內(nèi)外研究概況 .................................................................................................. 5 本課題的研究內(nèi)容 .............................................................................................. 5 本課題的研究目的與意義 .................................................................................. 6 第 2 章 MATLAB/SIMULIK基礎(chǔ)知識 ..................................................................... 7 MATLAB 介紹 ..................................................................................................... 7 MATLAB 主要組成部分 .............................................................................. 7 MATLAB 的系統(tǒng)開發(fā)環(huán) .............................................................................. 8 SIMULINK 仿真基礎(chǔ) .......................................................................................... 9 SIMULINK 啟動 ......................................................................................... 10 SIMULINK 的模塊庫介紹 ......................................................................... 11 電力系統(tǒng)模塊庫的介紹 ............................................................................. 12 SIMULINK 的仿真步驟 ............................................................................. 13 第 3 章 整流電路的 SIMULINK仿真設(shè)計 .............................................................. 15 單相橋式整流電路的仿真 ................................................................................ 15 單相橋式全控整流電路的工作原理 ......................................................... 15 建立仿真模型 ............................................................................................. 15 設(shè)置模型參數(shù) ............................................................................................. 17 模型仿真 ..................................................................................................... 18 三相橋式整流電路的仿真 ................................................................................ 21 三相橋式全控整流電路的工作原理 ......................................................... 21 建立仿真模型 ............................................................................................. 22 設(shè)置模型參數(shù) ............................................................................................. 23 第 4 章 斬波電路的 SIMULINK仿真設(shè)計 .............................................................. 26 降壓斬波電路 的仿真 ......................................................................................... 26 降壓變換器的工作原理 ............................................................................. 26 建立仿真模型 ............................................................................................. 27 設(shè)置模型參數(shù) ............................................................................................. 28 模型仿真 ..................................................................................................... 28 升壓斬波電路的仿真 ........................................................................................ 30 4 升壓變換器的工作原理 ............................................................................. 30 建立仿真模型 ............................................................................................. 30 設(shè)置模型參數(shù) ............................................................................................. 31 模型仿真 ..................................................................................................... 32 第 5 章 仿真調(diào)試 ......................................................................................................... 34 模型仿真應(yīng)注意的問題 .................................................................................... 34 模型建立和仿真參數(shù)的設(shè)置 ..................................................................... 34 仿真運行 和觀測仿真結(jié)果 ......................................................................... 35 結(jié) 論 ....................................................................................................................... 37 參考文獻 ....................................................................................................................... 38 致 謝 ........................................................................................................................... 40 5 第 1 章 概述 國內(nèi)外研究概況 電力電子技術(shù)綜合了微電子、電路、自動控制等多學科知識，是電能變換與控制的核心技術(shù)
