【正文】 load, to to control the output voltage by changing PWM, stable output is about 8V, and then through the current SCM algorithm to calculate the DCDC module and the total. According to the design requirements, adjust again PWM, so that the current distribution, at the same time in the process of sampling current, can do the flow limiting control, to protect the role. DC regulated power supply as the DC energy providers, in various kinds of electronic equipment, has an extremely important position, its performance is good or not directly affect the entire electronic products, precision, stability and U with the electronic technology development power technology also obtained the very big development, it is from the past a less plicated electronic circuits into today has the strong function of of stable power supply way, by traditional linear development to today39。實(shí)現(xiàn)電源穩(wěn)定的方式,由傳統(tǒng)的線性穩(wěn)壓發(fā)展到今天的開(kāi)關(guān)式穩(wěn)壓,電源技術(shù)正從過(guò)去附屬于其它電子設(shè)備狀態(tài),逐漸演變?yōu)橐粋€(gè)電子學(xué)科的獨(dú)立的分支 。 參考文獻(xiàn) ......................................................................................................... 20 11 級(jí)畢業(yè)生 專(zhuān)業(yè)研究報(bào)告 研究報(bào)告題目: 智能充電器 系 部: 機(jī)電與信息工程系 專(zhuān) 業(yè): 應(yīng)用電子技術(shù) 班 級(jí): 11 級(jí)應(yīng)電( 1)班 姓 名: 覃志忠 學(xué) 號(hào): 110302020 指 導(dǎo) 教 師: 李顯邦 完 成 時(shí) 間: 2020 年 10 月 21 日 智能充電器 摘 要 本系統(tǒng)由宏晶科技集團(tuán)的 8 位高速低功耗單片機(jī) STC12C5608AD 為控制核心,產(chǎn)生兩路 PWM 來(lái)驅(qū)動(dòng)開(kāi)關(guān)管 SFR9034 MOS 管結(jié)合自帶的 AD 做反饋,做成兩路可控的DCDC 電源,并用 Nokia5110 液晶屏顯示出當(dāng)前的電流值電壓值,當(dāng)改變負(fù)載的時(shí)候,通過(guò)改變 PWM 來(lái)控制輸出電壓,穩(wěn)定輸出在 8V 左右,然后通過(guò)單片機(jī)算法算出各DCDC 模塊 的電流及總的電流。 整流橋的簡(jiǎn)述 ......................................................................................................... 12 整流橋的應(yīng)用 ......................................................................................................... 13 4 MC34063A 介紹 ............................................................. 錯(cuò)誤 !未定義書(shū)簽。 5 硬件設(shè)計(jì)總體框架介紹 及程序 .................................... 錯(cuò)誤 !未定義書(shū)簽。按照設(shè)計(jì)要求,再次調(diào)節(jié) PWM,使電流按比例分配,同時(shí)在采樣電流的過(guò)程中,可以做限流控制,達(dá)到保護(hù)的作用。 現(xiàn)代電源技術(shù)是應(yīng)用電力電子半導(dǎo)體器件,綜合自動(dòng)控制、計(jì)算機(jī) (微處理器 )技術(shù)和電磁技術(shù)的多學(xué)科邊緣交叉技術(shù)。s switching regulated power supply technology from in the past, attached to other electronic equipment state, gradually evolved into a separate branch of electronic science. The power of modern technology is the application of power electronic semiconductor devices, automatic control, puter (microprocessor) technology and electromagic technology and multidisciplinary cross all kinds of high quality, high efficiency, high reliability of the power play a key role, is the modern power electronics technology regulated power supply has the advantages of stable performance, simple structure, convenient adjustment, the practical advantages of a wide range of applications.
