切換式磁阻馬達是一種構造簡單、堅固、製造成本低廉的電動機。由於轉速及轉矩的控制範圍較廣，故適用於高扭力定功率之場合，其應用日漸廣泛。所以，本論文提出一種低壓軟切的驅動控制，並應用霍爾電流感測器(Current Transducer)及近接感測器(Proximity Sensor)，來偵測激磁相電流及轉子凸極的位置與速度控制器，可改善換相偵測不佳所導致過換相或欠換相的問題。本論文利用3個不同案例來驗證改善換相電流的漣波技術，並藉由降低切換式磁阻馬達之換相電流漣波，來降低換相轉矩的漣波，並使用徳州儀器(TI) TMS 320F28335數位信號處理器(DSP)進行量測。其結果證實，本論文所提出的軟切驅動平台之控制確實可以有效降低切換式磁阻馬達的噪音與振動，並提升在高低速運轉的順暢度。

Switched Reluctance Motor (SRM) is a simple and reliable structure with an economic manufacturing cost. Due to the widely range control of velocity and torque, SRM is gaining more and more applications on high torque requirement field with constant power. So, this thesis propose a low-voltage of soft-switching driven control, and the use of hall current sensor (Current Transducer) and proximity sensor (Proximity Sensor) to detect the excitation phase current and rotor salient pole position and speed controller, so it can improve of commutation detection caused by over commutation or owe commutation of the problem. In this thesis, the use of three different cases to verify the commutation of the current ripple of the technology, by reducing the switched reluctance motor commutation current ripple,and use TEXAS INSTRUMENTS(TI) TMS320F28335 digital signal processor (DSP) for the measurement. The results confirmed that the proposed this thesis Switched Reluctance Motor application of the soft-switching drive platform control can reduce the noise and vibration effectively, and then improve the high and low velocity to operate more smoothly.
