摘要

本論文實現雙向倍壓前端轉換器的磁阻馬達驅動系統，其電路之特色為提昇電流響應速率、轉矩能力、減少電流與轉矩漣波，且僅需一個單電流感測器，並降低電流感測器體積及成本。另一方面，系統具有雙向功率潮流之功能，再生制動能量能回收至電池作為充電。本文使用12/8三相磁阻馬達、非對稱式半橋轉換器以及雙向倍壓前端轉換器。由雙向倍壓前端轉換器提供相電感激磁、去磁為雙倍電壓源作為快速激磁、快速去磁的電壓，並詳細分析電路組態及波形，經由模擬驗證及評估可行性。使用FPGA(Field Programmable Gate Array)硬體電路晶片實現本文所提出控制器設計方法，驗證是否達成控制目標及功能，並討論模擬與實作結果。

In this paper, a bidirectional voltage-doubler front-end converter for switched-reluctance motor (SRM) driver is proposed and implemented. The SRM drive consists of an asymmetric half-bridge topology used to drive a 12/8 three phase reluctance motor. The proposed topology incorporates fast excitation and demagnetization in order to improve the current tracking speed, the torque capacity, and reduce the torque and current ripple. In addition, the proposed topology only requires one current sensor thus reducing its cost. Furthermore, the system realizes regenerative breaking. The feasibility of the proposed topology is demonstrated through simulation and experimental results obtained using Field Programmable Gate Array (FPGA) for the control system.
