A High Gain DC-DC Converter based FC-Battery-SC System for EV Application

This paper presents an approach for electric vehicle (EV) applications through the implementation of a Dual Switch Switched Capacitor (DSSC) boost converter based Fuel Cell (FC) and Bi-Directional (BD) converter based battery-Super Capacitor system. The proposed system integrates multiple energy sources to enhance overall performance and efficiency. The dual switch boost converter acts as an intermediary between the fuel cell, enabling seamless power flow with Maximum Power Point Technique (MPPT). The BD converter with Energy Storage Systems (ESS) delivers in case of less supply power from FC and absorbs the excess power when the load is running at low power. By intelligently utilizing the characteristics of each energy storage element, the system optimizes energy conversion, storage, and distribution, resulting in improved EV performance, extended range, and reduced dependency on a single energy source. A 2000 W/ 100 V system is designed using the FC-battery-SC model with consideration of equivalent motor load. The detailed analysis demonstrates the superiority of the proposed FC-battery-SC system over conventional approaches, offering promising prospects for future EV applications.
