本論文針對電動車應用提出並研製一套內藏型永磁馬達之再生制動系統。此系統以最大功率回收之磁場導向控制及三相全橋換流器為基礎，將馬達煞車時產生之電能回收至超級電容與直流電源，達成馬達煞車控制及能量回收之目的。本系統有別於方波制動及傳統磁場導向控制(將直軸電流控制為零)制動，根據內藏型永磁馬達其直、交軸電感不同之特性，加入直軸電流進行磁場導向制動，使內藏型永磁馬達產生最大之定子輸出電功率，於制動過程中得到最大功率回收。利用超級電容能夠快速充放大電流、循環壽命長且工作溫度範為寬等特性，於馬達需要加速時，將直流側切換為超級電容進行供電，藉此延長電池之壽命。本論文針對所提出之再生制動系統進行模擬分析，並於雛形系統進行實測，驗證本論文所提出之架構。

This thesis proposes a regenerative braking system for interior permanent magnet (IPM) motor applied to electric vehicle tractions. The system consists of a three-phase full-bridge inverter, a controller and supercapacitor bank. When operating in the braking mode, the motor is forced to act as a generator and convert the mechanical power into electrical power that is stored in the supercapacitor bank. The proposed control approach is different from the six-step commutation braking and traditional field-oriented control (FOC) braking. Since the d-q-axis inductances are different due to the saliency in the IPM motor, the d-axis current should also affect the regenerative power. The d-axis current component is considered in the FOC braking control can maximize the IPM motor regenerative power. The supercapacitor, which to operate in high current charging and discharging conditions, is used to provide the energy for motor acceleration. This can extend the life cycle of batteries. The proposed system is simulated using coupled field-circuit analysis (Maxwell-Simplorer) and verified by experiments on HIL.
