隨著電動車產業興起，如何把電動機控制得好且穩定將會是未來研究的重點之一。本文目標在於以數位控制方式實現三相感應電動機之驅動電路。使用間接式轉子磁場導向控制法當作控制架構，並以空間向量脈波寬度調變來控制開關訊號，達到提升直流電壓利用率的目的。編碼器用來計算當下的轉速並回授給數位控制器，進而完成馬達轉速及電流之閉迴路控制；其中還有加入軟啟動來改善啟動時電流突波的問題。本文會先介紹感應電動機模型，進一步討論控制方法，並輔以PSIM模擬軟體來驗證其控制法的可行性。實作部分是採用德州儀器公司之數位訊號處理器TMS320F280049C做為控制核心，最後實作一台輸出功率20 kW、輸入直流電壓400 V之三相感應電動機驅動電路。

Due to rise of electric vehicle industry, it will be important research that how to control the motor well and stable in the future. This thesis aims to implement a three phase induction motor driver of digital control. Indirect Rotor Field Oriented Control is adopted as the control architec-ture and use the space vector pulse width modulation(SVPWM) to con-trol the switch signal in order to achieve to increase the DC Voltage Uti-lization. Feedback speed is measured by the encoder to achieve the closed loop of speed and current. In addition, soft start is added to improve the current spike at circuit started. Firstly, the three phase induction motor model is introduced, and the control strategy is discussed. Then, this thesis uses the simulation software PSIM to verify the feasibility of the control. The digital signal processor TMS320F280049C from Texas In-strument is used in the experiment and implementing a 20 kW output power and 400 V input DC voltage three phase induction motor driver.
