【正文】 MOUMOU 職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計 題目：數(shù)字電壓源的設(shè)計 系 部 專 業(yè) 名 稱 班 級 姓 名 學(xué) 號 指 導(dǎo) 教 師 2021 年 6 月 14 日 數(shù)字電壓源的設(shè)計 摘要 電源技術(shù)尤其是數(shù)字電源技術(shù)是一門實踐性很強(qiáng)的工程技術(shù)，服務(wù)于各行各業(yè)。當(dāng)今電源技術(shù)融合了電氣、電子、系統(tǒng)集成、控制理論、材料等諸多學(xué)科領(lǐng)域。隨著計算機(jī)和通訊技術(shù)發(fā)展而來的現(xiàn)代信息技術(shù)革命，給電力電子技術(shù)提供了廣闊的發(fā)展前景，同時也給電源提出了更高的要求。隨著數(shù)字電源在電子裝置中的普遍使用，普通電源在工作時產(chǎn)生的誤差，會影響整個系統(tǒng)的精確度。電源在使用時會造成很多不良后果，世界各國紛紛對電源產(chǎn)品提出了不同要求并制定了一系列的產(chǎn)品精度標(biāo)準(zhǔn)。只有滿足產(chǎn)品標(biāo)準(zhǔn)，才能夠進(jìn)入市場。隨著經(jīng)濟(jì) 全球化的發(fā)展，滿足國際標(biāo)準(zhǔn)的產(chǎn)品才能獲得進(jìn)出的通行證。數(shù)字電源是從 80 年代才真正的發(fā)展起來的，期間系統(tǒng)的電力電子理論開始建立。單片機(jī)技術(shù)及電壓轉(zhuǎn)換模塊的出現(xiàn)為精確數(shù)字電源的發(fā)展提供了有利的條件。到 90年代，己出現(xiàn)了數(shù)字精度達(dá)到 的數(shù)字電源。從組成上，數(shù)字電源可分成器件、主電路與控制等三部分。目前所使用的直流可調(diào) 電源 中 ,幾乎都為旋紐開關(guān)調(diào)節(jié)電壓 ,調(diào)節(jié)精度不高 ,而且經(jīng)常跳變 ,使用麻煩。利用 數(shù)字 電源 ,可以達(dá)到每步 的精度 ,輸出電壓范圍 0~12V。 關(guān)鍵詞 ：數(shù)字電源技術(shù)，工程，電子，變化，精度。 The design of digital voltage source Abstract Power technology, especially digital power technology is a strong practical engineering, to serve all walks of life. Power of technology convergence in today39。s electrical, electronics, systems integration, control theory, materials, and many other fields. With the puter and munication technologies developed from the modern information technology revolution, the power of electronic technology to provide a broad development prospects, but also to a higher power requirements. With the number of power electronic devices in general use, the power of ordinary working hours in the error will affect the accuracy of the entire system. Power in use will cause a lot of negative consequences, countries around the world for power products and the different requirements put forward a series of products to develop standards for accuracy. Only to meet the product standards to be able to enter the market. With the development of economic globalization, the products meet international standards in order to obtain access to the permit. Digital Power is from the 8039。s really developed during the system to start building power electronics theory. Singlechip technology and the emergence of voltage conversion module for the development of accurate digital power provided favorable conditions. To 90 years, there has been a digital accuracy of the digital power . From the position, the digital power supply can be divided into ponents, such as main circuit and control of three parts. DC current adjustable power supply, almost xuanniu switch for regulating voltage regulation accuracy is not high, often hopping, the use of trouble. The use of digital power, to achieve the accuracy of each step, the output voltage range of 0 ~ 12V. Key words: digital power technology, engineering, electronics, range. 目錄 前言 ................................................................................................................................ 5 概述 ................................................................................................................................ 6 設(shè)計內(nèi)容 ........................................................................................................................ 7 一、設(shè)計要求： ..................................................................................................... 7 二、材料和工具： ................................................................................................. 7 材料： ...................................................................................................
