A Bi-directional DC-DC Power Converter Topology Based on Efficiency for Electric Bike

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

The adoption of electric bikes is growing exponentially worldwide. However, the existing electric bike (e-bike) chargers are costly and lack essential features such as proper authentication, real-time monitoring, parameter analysis, and effective maintenance. In this work, a bidirectional DC-DC converter is designed to improve the performance of a regenerative braking system and increase the battery lifetime in electric bicycles. Compared to the traditional design concepts, the proposed method includes higher-level control algorithms and enhanced control of the switching methods, which makes the system perform optimally. Also, a comparative study has been conducted with other topologies to clearly highlight the enhanced energy recovery, battery durability, and effectiveness of the proposed converter. The obtained results demonstrate the improved efficiency of the proposed topology, revealing its advantages over conventional topologies.
