近年來，由於碳化矽功率元件的高切換頻率、低導通電阻與高耐溫等優點，使得碳化矽功率元件逐漸取代傳統的矽功率元件，且逐漸應用於馬達驅動系統，使馬達驅動器往高功率密度、高效率與高操作頻率來發展。本論文的目標，係以探討寬能隙碳化矽功率元件應於永磁同步馬達驅動器之系統響應分析。
　　本論文使用MATLAB/Simulink整合電壓源變流器、磁場導向控制法與永磁同步馬達，建立一套具碳化矽功率元件的永磁同步馬達驅動控制系統，透過模擬可知，提高變流器的切換頻率，可提升轉速的動態響應，也可改善三相電流的總諧波失真。本論文亦製作一具碳化矽功率元件之3.7 kW永磁同步馬達驅動控制系統，以實測驗證模擬所得到之分析結果。

In recent years, silicon carbide (SiC) power transistors have gradually replaced traditional silicon power transistors because of SiC’s advantages such as higher switching frequency, lower resistance, and higher operating temperature This thesis presents the system response analysis of permanent magnet synchronous motor driver based on silicon carbide power transistors. In this thesis, MARLAB/Simulink is used to build a permanent magnet synchronous motor drive and control system with silicon carbide power transistors. The motor system is composed of a voltage source inverter, field-oriented control method and a permanent magnet synchronous motor. It can be observed from the simulation that the dynamic response of the speed and the total harmonic distortion of the three-phase current can be improved by increasing switching the frequency.
Finally, a 3.7kW prototype of permanent magnet synchronous motor driver based on silicon carbide power transistor is implemented. Then, experimental results of the prototype are used to validate simulated results.
