Regenerative braking for induction motor drive

High power rating and robustness of AC drive has made Induction motor based motion control a preferable choice in the industrial applications. This paper embarks on the issues of bidirectional power conversion, regenerative braking and energy storage. A simplified and cost effective method of three phase inverter fed induction motor drive capable of regenerative energy storage is discussed. This method is very useful for Hybrid Electric Vehicles, Traction Drive and hoist drive applications. The proposed method is focused on smooth control and energy efficiency of AC drive systems. A simulation model has been developed for the analysis of system dynamics and power flow. Also a microcontroller based experimental setup for one kilowatt induction motor is proposed. Further the obtained simulation results are validated and compared with the experimental results.
