Abstract: Regenerative braking has been playing a significant role in electric locomotives to overcome dissipation of the kinetic energy as heat. For high-speed rail topologies, Power electronic transformer based locomotive has the only solution to achieve it. For the isolation purpose and to reduce the weight of the locomotive, a feasible method by substituting loco transformer with a transformer with high frequency design. With the increasing awareness of energy consumption more electrified locomotives now moving to “Green Energy “. This paper aims to describe the importance of hybrid electric locomotive system when compared to conventional one. By integrating the regenerative braking on power electronic transformer with a storage medium will be a promising solution for the future high-speed rails. The simulation of IGBT based dc to dc converter with traction inverter with storage medium has simulated from MATLAB/ SIMULINK platform.
