【正文】 本科畢業(yè)設(shè)計論文論文題目： 基于單片機的單相電機調(diào)速系統(tǒng) ——電源電路的設(shè)計 作者姓名 指導(dǎo)教師 所在院系 專業(yè)班級 　　　 提交日期 ____2022 年 5 月 II基于單片機的單相電機調(diào)速系統(tǒng)——電源電路 摘 要本文簡單介紹了單相電機的工作原理及變頻調(diào)速原理，同時詳細介紹了開關(guān)電源的工作原理?；谶@些理論設(shè)計了相應(yīng)的電源電路，將 200AC 電源整流后提供給單片機，并設(shè)計了一開關(guān)電源作為控制電路和單片機及外圍電路的電源。另外根據(jù)單相電機的參數(shù)，選擇合適的驅(qū)動芯片和驅(qū)動管，實現(xiàn)對單相電機的驅(qū)動。本文作者還完成了原理圖和 PCB 板的設(shè)計以及硬件調(diào)試。本系統(tǒng)成本不高，采用了脈寬調(diào)制技術(shù)組成的 PWM 交直交變頻裝置。關(guān)鍵字：單相電機，變頻調(diào)速，開關(guān)電源，驅(qū)動III目錄摘要
