Analysis and Control of DAB converter for EVs charging stations

Abstract

The ongoing shift towards electric vehicles (EVs) has emphasized the need for efficient and reliable charging systems. This thesis presents an in-depth analysis of the Dual Active Bridge (DAB) converter, a key component for EV charging stations. The DAB converter’s bidirectional power flow and galvanic isolation make it highly suitable for both charging and discharging scenarios, particularly in Vehicle-to-Grid (V2G) applications. The research focuses on the DAB’s operational principles, power transfer mechanisms, and the implementation of control strategies to enhance efficiency and stability. Simulation results demonstrate the viability of the DAB converter in handling high power levels, ensuring fast charging, and maintaining system reliability under different operating conditions. Overall, this work contributes to the development of advanced EV charging infrastructure, aligning with the growing demand for sustainable energy solutions.
