Abstract

This abstract presents a study on Electric Vehicle (EV) battery chargers using Phase Shifted Full Bridge (PSFB) converter topology. As the demand for electric vehicles continues to grow, efficient and reliable charging solutions are of paramount importance. The PSFB converter topology has gained significant attention due to its ability to provide high-power conversion with improved efficiency and reduced stress on the power devices. This paper focuses on analyzing the design, operation, and control aspects of an EV battery charger employing the PSFB converter topology. The study begins with an overview of the PSFB converter topology, discussing its advantages and suitability for high-power applications. The operation principles of the PSFB converter and the key components involved are presented, including the full bridge rectifier, resonant tank, and control circuitry. The converter's ability to achieve soft switching and zero-voltage switching is highlighted, enabling reduced switching losses and improved efficiency. Simulation results are presented to validate the performance of the EV battery charger using the PSFB converter topology. The analysis includes efficiency measurements, power factor evaluation, and harmonic distortion assessment. Comparative studies with other converter topologies commonly employed in EV chargers are conducted to highlight the advantages of the PSFB converter. Finally, the paper concludes with a discussion on the practical implementation and challenges associated with the proposed EV battery charger using the PSFB converter topology. Safety considerations, thermal management, and system integration aspects are considered, aiming to provide a comprehensive understanding of the implementation feasibility and potential future research directions.
