基于DSP28035的高速永磁無刷直流電機(jī)驅(qū)動系統(tǒng),包括論文和軟硬設(shè)計資料。摘要參賽作品為基于DSP28035的高速永磁無刷直流電機(jī)驅(qū)動系統(tǒng)。該系統(tǒng)以一臺額定轉(zhuǎn)速60 krpm的高速永磁無刷直流電機(jī)、交錯并聯(lián)的Buck電路以及全橋電路為硬件平臺,以DSP28035為控制核心,實現(xiàn)了調(diào)壓調(diào)速功能和基于坐標(biāo)變換的無位置傳感器新技術(shù)。為實現(xiàn)該系統(tǒng)要求,本作品充分利用了DSP28035的資源例如:CLA模塊,模擬比較器、HPWM模塊以及AD轉(zhuǎn)換模塊等。AbstractThis work is the drive system for a high speed permanent magnet burshless dc motor based on DSP28035. The hardware platform consists of a BLDC motor(rated speed is 60000rpm), a Buck circuit and an inverter. Under the control of DSP28035, this system can achieve the goal of adjusting the motor’s speed with voltage and the function of sensorless control based on the coordinate transformation. By making full use of resources of the core, such as CLA, analog comparator, HPWM and AD converters, the whole system can meet the requirements.1 引言高速永磁無刷直流電機(jī)驅(qū)動系統(tǒng)由于基波頻率較高(一般在1kHZ以上),利用逆變橋斬波進(jìn)行調(diào)速的控制方式通常會受到開關(guān)管開關(guān)頻率的限制,因此該系統(tǒng)多采用三相全橋前級加Buck電路進(jìn)承擔(dān)調(diào)壓調(diào)速的功能,而三相全橋主要承擔(dān)邏輯換相的功能。然而,傳統(tǒng)Buck電路所需電感的體積較大,增加了系統(tǒng)的體積,降低了系統(tǒng)的功率密度。

為了滿足一些重要用電設(shè)備的連續(xù)供電,對電網(wǎng)供電提出了更高的要求。為此,引入一種新型UPS是不間斷電源(uninterruptible power system)的英文簡稱,是能夠提供持續(xù)、穩(wěn)定、不間斷的電源供應(yīng)的重要外部設(shè)備。UPS先將交流電直流成直流電,一路給蓄電池充電,一路經(jīng)逆變器變成恒壓恒頻的交流電,不論是市電供電還是斷電由電池供電,總是通過逆變系統(tǒng)提供電力,因而市電停電或來電時無任何轉(zhuǎn)換間斷,市電的干擾也完全不影響到UPS的輸出端,另外,UPS提供的電力為純凈的正弦波交流電,適用的負(fù)載范圍寬,可以為多種精密用電設(shè)備提供穩(wěn)定的不間斷電源,此外,UPS的優(yōu)點還在于它的零轉(zhuǎn)換時間以及高質(zhì)量的輸出電源品質(zhì),因此它更適合于一些關(guān)鍵性的應(yīng)用場合.UPS由于其工作方式是先對電池充電,然后再由逆變器將電池的電能逆變成交流,因此在電能的轉(zhuǎn)化過程中有一部分電能將被損失掉。電子技術(shù)是根據(jù)電子學(xué)的原理,運(yùn)用電子器件設(shè)計和制造某種特定功能的電路以解決實際問題的科學(xué),包括信息電子技術(shù)和電力電子技術(shù)兩大分支。信息電子技術(shù)包括Analog(模擬)電子技術(shù)和Digital(數(shù)字)電子技術(shù)。電子技術(shù)是對電子信號進(jìn)行處理的技術(shù),處理的方式主要有:信號的發(fā)生、放大、濾波、轉(zhuǎn)換。現(xiàn)代電力電子技術(shù)的發(fā)展方向,是從以低頻技術(shù)處理問題為主的傳統(tǒng)電力電子學(xué),向以高頻技術(shù)處理問題為主的現(xiàn)代電力電子學(xué)方向轉(zhuǎn)變。電力電子技術(shù)起始于五十年代末六十年代初的硅整流器件,其發(fā)展先后經(jīng)歷了整流器時代、逆變器時代和變頻器時代,并促進(jìn)了電力電子技術(shù)在許多新領(lǐng)域的應(yīng)用。八十年代末期和九十年代初期發(fā)展起來的、以功率MOSFET和IGBT為代表的、集高頻、高壓和大電流于一身的功率半導(dǎo)體復(fù)合器件,表明傳統(tǒng)電力電子技術(shù)已經(jīng)進(jìn)入現(xiàn)代電力電子時代。
