全數位脈波寬度調變控制器應用於直流-直流升壓轉換器

Digital PWM controller for DC-DC Boost Converter

摘要


本論文主要是以實現以及驗證數位脈波寬度調變控制器之積體電路設計,脈波寬度調變技術目前已經廣泛使用於現在許多電力電子系統之中,以提昇系統電路的性能,並且達到省能與高效率之目的。而本數位控制電路主要是以PID控制器以及脈波寬度調變控制器之原理爲設計基礎作改良,相較於平常用查表法來完成補償器的作法,大幅地省下許多記憶體的面積,並且僅利用PI補償器,更省下了微分補償器的面積,電源級直流-直流升壓型轉換器之輸出電壓經過類比數位轉換器而成爲控制迴授信號,而經由類比數位轉換器所轉換出來的數位碼經過編碼將作爲後端數位控制器的輸入;而後端數位控制器將利用FPGA板作爲電路實現的元件,並利用Quartus軟體作爲模擬完成電路系統之設計,最後將電源級升壓型轉換器和後端數位控制器作結合來驗證在Matlab和Quartus軟體上面模擬的結果,經由這樣的方式去實現電路的基本架構、運作原理、電路功能,進而在來研究及應用於不同的環境需求,期許數位脈波寬度調變控制器之積體電路設計能朝更完善的方向前進。
