Abstract

The rapid adoption of electric vehicles (EVs) necessitates the development of efficient and reliable fast charging stations. This work presents a comparative analysis of various existing power converter topologies with the proposed topologies that are used in fast EV charging stations, focusing on their efficiency, cost, complexity, and performance. The study covers traditional and emerging converter topologies, including isolated and non-isolated designs, multi-level converters, and soft-switching techniques. Key performance metrics such as device count, charging voltage and source harmonics are evaluated. The analysis highlights the trade-offs between different topologies, providing insights into the optimal design choices for specific applications. The findings indicate that while non-isolated topologies offer higher efficiency and lower cost, isolated topologies provide better safety and flexibility. Multi-level converters show promise in reducing harmonic distortion and improving power quality, while soft-switching techniques enhance efficiency and thermal performance. This comparative study aims to guide engineers and designers in selecting the most suitable power converter topology for fast EV charging stations, ultimately contributing to the advancement of EV infrastructure and the acceleration of sustainable transportation solutions.
