WebIn 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. The braking is the process of reducing the speed of an induction motor. In braking, the motor works as a generator developing a negative torque which opposes the motion The braking is mainly classified into three types i.e., regenerative braking, plugging or reverse voltage braking, dynamic braking.
