PLUGGING BRAKING FOR ELECTRIC VEHICLES POWERED BY DC MOTOR
1 PG Scholar Department of Electrical Engineering, Sree Buddha College of Engineering, Pattoor, Alappuzha 2 Asst professor Department of Electrical Engineering, Sree Buddha College of Engineering, Pattoor, Alappuzha AbstractElectric traction is a promising technology that can bring out significant improvement in vehicle performance, fuel efficiency and energy utilization. The energy management in the traction system can be well improved through the braking system used in it. In this paper a electrical braking system i.e. plugging braking of DC motor is discussed. Model of DC-DC converter and controller was developed. After combining these models with DC motor simulation was conducted. Control scheme designed and implemented to the system was a speed controller. Optimization of controller following with verification would complete the overall model. Plugging braking was presented by simulation and waveform results were discussed. Reference speed were varied and simulated. Speed-up time and braking time were discussed. Conclusions were drawn at the end of the paper. Keywords-Electric vehicle, DC motor, DC-DC converter, plugging braking.
