RESEARCH AND DESIGN OF REGENERATIVE BRAKING FOR ELECTRIC VEHICLES USING BLDC MOTOR

Abstract

Brushless DC (BLDC) motors are widely used in electric cars and electric motorcycles because of their efficiency, high energy density, and ease of control and maintenance. The paper proposes a simple, low-cost method to reuse the motion energy of electric vehicles using BLDC motors during braking. The three-phase bridge converter structure is decomposed into three DC boost converter operating in combination. The paper also presents the control structure, simulation circuit and experimental devices for the regenerative braking process to return energy to the source. Simulation results on PSIM software and experimental results show the ability to regenerate energy, accuracy and efficiency of the built device.
