摘要:電源技術(shù)尤其是數(shù)控電源技術(shù)是一門實(shí)踐性很強(qiáng)的工程技術(shù)，服務(wù)于各行各業(yè)。電力電子技術(shù)是電能的最佳應(yīng)用技術(shù)之一。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(jì)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(shí)也給電源提出了更高的要求。該直流穩(wěn)壓電源的輸入為交流22OV，50Hz，輸出電壓為1.5V—13V內(nèi)連續(xù)可調(diào)，輸出電流為500mA以上，并能夠直觀的顯示輸出電壓。電源的控制電路選用STC89C52單片機(jī)為核心，以及數(shù)/模轉(zhuǎn)換功能，具有線路簡單、穩(wěn)定性好、顯示清晰直觀等特點(diǎn)。文章中分析了電源的整體結(jié)構(gòu)和工作原理，并詳細(xì)的講述了穩(wěn)壓電路、數(shù)/模轉(zhuǎn)換電路、顯示電路等電路的工作原理。給出了控制電路的硬件實(shí)現(xiàn)和主要的軟件流程設(shè)計(jì)。 關(guān)鍵詞 單片機(jī)；數(shù)碼管；數(shù)/模轉(zhuǎn)換；穩(wěn)壓
Abstract:Digitally controlled power supply technology, especially technology is a strong practical engineering technology, and service to all industries. Power electronics technology is the best application of energy technologies. Technology combines the power of today's electrical, electronics, systems integration, control theory, materials, and many other subject areas. With the computer and communication technologies developed from modern information technology revolution, to the power electronics technology to provide a broad development prospects, but also to set a higher power supply requirements. The DC power supply input for the exchange of 22OV, 50Hz, output voltage of 1.5V ~ 13V continuously adjustable output current of 500mA or more and be able to display visual output voltage. Power supply control circuit use STC89C52 microcontroller as the core, as well as D / A converter functions, with simple circuit, good stability, showing a clear and intuitive and so on. The article analyzes the power of the overall structure and working principle and in detail about the pre-regulator circuit, D / A converter circuit, display circuit so the circuit works. Gives the control circuit hardware implementation and the main software flow. Key words: SCM; digital pipe; D / A converter; Regulators
