    Abstract: 本論文主要針對電動車常用的無刷直流馬達,探討常用的煞車回充之方法,提出一個新的能量回收方法,本文所提及的煞車回充方法,應用升壓式電壓轉換器的原理,將動能轉換為電能,藉由改變反流器之開關訊號,以達到可控制反向扭力煞車的目的。最主要優點,不需要添加額外的電路轉換,或者改變馬達的繞阻結構來達成煞車能量回收。除此之外,本文以低成本方式設計電動車驅動器,驅動器包含功率開關驅動電路、電源電路、電流偵測電路、過電流偵測電路以及MCU周邊電路……等,最後,使用慣性負載來模擬實際行駛狀況,實現煞車回充;透過磁粉測功機來測試驅動器效率、力矩以及電流等特性。;This thesis proposes a novel method of dynamic braking for the brushless DC motor (BLDCM) of the electric vehicle (EV). Dynamic braking methods discussed in this thesis, use voltage boost converter principle to convert the kinetic energy into electrical energy. By changing the switching signals of motor driver,one could control the reverse torque during the braking period. The main advantage is that no additional converter or changing stator windings to achieve the goal of the energy recovery. In addition, a low-cost driver is designde to electric vehicles in this paper. Electric vehicles drive includes a power switch driving circuits, power supply circuits, current detection circuits, over-current detection circuits, an MCU and peripheral circuits ...etc. Finally, an the inertial load is used to simulate actual driving conditions, such as regenerative braking.
