摘要

本論文提出一應用可調角度ds-qs軸轉換之三相電流型感應馬達驅動器，此驅動器應用可調角度ds-qs軸轉換技術，以降低忽略感應馬達反電勢所造成之開關切換次數增加。由磁滯電流控制器控制電流與開關切換狀態，並利用電壓空間向量規劃一切換表，使本驅動器有效的管理開關切換次數，降低切換損失進而提升整體系統的效率。使用德州儀器所開發之數位訊號處理器TMS320F28335搭配控制軟體VisSim以實現數位化的控制。最後，提出部份實驗結果以驗證本文之驅動器之可行性。

In this thesis, the application of a adjustable angle ds-qs axis transformation for three-phase current source induction motor drive is proposed. In order to reduce higher switching number caused by ignoring induction motor back EMF, the drive is applied to the ds-qs axis transformation with adjustable angle technology. Using hysteresis current controller and voltage space vector, the status of switches can be programmed effectively in the switching table. Therefore, the proposed drive has lower switching loss and higher system efficiency. VisSim simulation software and DSP TMS320F28335 are adopted to implement the digital control. Finally, some experimental results are presented to verify the feasibility of the proposed drive.
