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. |
