Regenerative braking in induction motor drives in applications to Electric Vehicles

Electric 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 regeneration. In this paper, a method for regenerative braking has been proposed in which the induction machine is operated with negative slip to obtain braking torque. Regeneration during deceleration of electric vehicle is demonstrated by controlling supply frequency and voltage.
