本論文旨在研製高性能切換式磁阻馬達功率轉換器。如何迅速地讓相電流完成激磁與去磁的動作，是切換式磁阻馬達功率轉換器設計上的主要考量。因此本論文探討切換式磁阻馬達各種結構特性、數學模型、控制原理，並針對各種功率轉換器的動作模式與特性加以分析研究。在所探討之各種轉換器架構中，因四階轉換器具提高切換式磁阻馬達效率與性能等優點，且僅增加了儲能電容與開關元件，因此本論文針對此架構推導出計算其儲能電容之方程式，使得驅動器參數設計能更有效率。為驗證四階轉換器的參數設計與控制方法是否無誤，以減少實作時可能產生的問題，本論文運用驅動器研發與馬達結構設計軟體進行聯合模擬分析。最後採用Microchip公司生產的dsPIC30F4011為控制核心，針對三相6/4切換式磁阻馬達設計與實作完整的硬體電路及軟體程式，並進行各項性能驗證。由實驗結果證實，相較於非對稱半橋轉換器，使用四階轉換器確實能達到切換式磁阻馬達性能與效率的提升。

The main purpose of this thesis is to develop a high-performance power converter for Switched Reluctance Motors (SRMs). How to accelerate the process of excitation and demagnetization of the phase current is one of the main considerations when designing the power converter for SRMs. Therefore, this thesis investigates the structure, mathematical model and control principle of SRMs, and also analyzes the action modes and characteristics of several kinds of power converters for SRMs. Among the power converters investigated, the four-level converter has advantages such as higher efficiency and performance with the price of requiring extra charge capacitors and switching elements. In order to facilitate the design of the four-level converter, this thesis derives the equation for determining the charge capacitor so that the parameter design of the drive circuit can be more efficient. In this thesis, an electric circuit and motor design software are employed to simulate the 6/4 SRM and ensure that the designed parameters and control methods of the four-level converter are correct. The reasoning is problems which may occur during practical implementation can be substantially reduced. Finally, the microcontroller dsPIC30F4011 produced by Microchip Corporation is used as the control kernel when implementing the drive circuit for the 6/4 SRM. Several experiments have been conducted to evaluate the performance of different power converters for the 6/4 SRM. Experimental results show that the performance of the 6/4 SRM driven by the four-level converter is better than that of the 6/4 SRM driven by the asymmetric power converter.
