摘要

本論文旨在開發以數位訊號處理器為主具邱克切換式整流器前級之切換式磁阻馬達驅動系統。首先，在探究切換式磁阻馬達之結構、物理建模、常用轉換器及動態控制後，設計實作一具二極體整流器前級之切換式磁阻馬達驅動系統。由詳細實測評估驗證其良好之操控性能，含加速、減速及反轉等操作特性。此外，更藉由進一步之實測觀察，以體會影響二極體整流器供電切換式磁阻馬達驅動系統操控性能之關鍵事務，重要特性含換相移位之功效、變動直流鏈電壓之效應、以及交流入電電力品質等。
接著，在探究一些可能升-降壓型切換式整流器之比較特徵後，選擇建置一邱克切換式整流器作為切換式磁阻馬達驅動系統之入電前級。其良好直流輸出電壓及交流入電電力品質得益於輸入及輸出側均連續之電流。所建切換式整流器供電切換式磁阻馬達驅動系統，其電路設計、動態建模、及採行斜率比較電流控制與磁滯電流控制之性能比較評估等均有詳實介紹。
最後，為了提升能量轉換效率，本論文開發一無橋式邱克切換式整流器。並從事以二極體整流器、標準邱克切換式整流器、及無橋式邱克切換式整流器供電切換式磁阻馬達驅動系統之操控性能實測比較評估。

This thesis is mainly concerned with the development of a digital signal processor (DSP) based switched-reluctance motor (SRM) drive with single-phase Ćuk switch mode rectifier (SMR) front-end. After exploring the structure, physical modeling, commonly used converter and dynamic controls for SRM, a standard diode rectifier fed SRM drive is designed and implemented. The detailed experimental evaluation verifies its satisfactory driving performance in acceleration, deceleration and reversible operations. In addition, further experimental observations are conducted to comprehend some key issues affecting the operating characteristics of SRM drive powered by diode rectifier under higher speed and heavier load. The major observed characteristics include effectiveness of commutation instant shift, effects of DC-link voltage variation and AC input power quality.
Next, some possible buck-boost SMR schematics are comparatively explored. Then a Ćuk SMR is established and employed as the front-end of the developed SRM drive. Well regulated DC output voltage and good AC input line drawn power quality are obtained thanks to its continuous currents at both input and output sides. The circuit design, dynamic modeling and performance comparative assessment of the established SMR-fed SRM drive using ramp-comparison current-controlled PWM (RC-CCPWM) and hysteresis current-controlled PWM (H-CCPWM) schemes are all conducted in detail.
Finally, for improving the energy conversion efficiency, a bridgeless Ćuk SMR is further developed. And the SRM drives fed by diode rectifier, standard Ćuk SMR, and bridgeless Ćuk SMR are comparatively evaluated.
