Abstract: This paper presents an overview and an approach of regenerative braking system for energy harvesting from railways and vehicles. In this paper. after a brief introduction, the focus is on literature review wherein we have studied 15 papers related to the topic and have successfully analyzed them. On the basis of the literature review, we have proposed a system which can offer higher economic benefits by lowering the operation costs of supplying energy to train stations. The topology and the control strategy for battery chargers on high-speed electric trains are also discussed.

Keywords: Regenerative braking system, energy harvesting, regenerative mechanisms
