The rise in the number of electric vehicles used by the consumers is shaping the future for a cleaner and energy-efficient transport electrification. The commercial success of electric vehicles (EVs) relies heavily on the presence of high-efficiency charging stations. This article reviews the design and evaluation of different AC/DC converter topologies of the present status and future implementation plans for DC fast-charging infrastructures. The design and evaluation of these converters are presented, analysed, and compared in terms of output power, component count, power factor, and total harmonic distortion effectiveness and reliability. This paper also evaluates the architecture, merit, and demerits of AC/ DC converter topologies for DC fast-charging stations. Based on this analysis, it has found that the Vienna rectifier is the best suitable converter topology for the high-power DC fast-charging infrastructure (> 20 kW), thanks to its low current ripples, low output voltage ripples, high efficiency, high power density, and high reliability. The paper focuses specifically on different topologies of Vienna rectifier topologies on Level-3 DC fast-charging stations which direct to less CO 2 emissions in electric vehicle charging stations, thus contributing to sustainable development goals of climatic action.

This paper introduces a level 3 charging system which aims to reduce the charging time to less than 15 minutes with 350 kW charging power. Two architectures of a fast charging station based on the isolation requirement through low and high-frequency transformers are introduced and discussed. Focusing on the DC-DC charging stage, this paper also provides a detailed comparison of the Dual Active Bridge (DAB) converter and the Interleaved Buck Converter (IBC), which are considered as two of the most suitable converters that can serve as a fast DC charger. Technical evaluation and comparison based on different performance indices such as volume, efficiency, number of components etc. as well as simulation of the two converters are presented. Finally, comparison results are introduced and a final discussion and conclusion are presented on which topology seems more optimum to be used as a fast DC charger.

The commercial success of electric vehicles (EVs) relies heavily on the presence of high-efficiency charging stations. This paper provides an overview and a comprehensive performance comparison of the present status and future implementation plans for DC fast charging infrastructures and converter topologies. The paper also discusses critical consequences of DC fast charging stations on the AC grid. Different power converter topologies for DC fast charging are presented, compared, and evaluated, based on the power level requirements, efficiency, cost, and technical performance specifications. The paper focuses specifically on Level-3 DC fast charging converter topologies and their performance comparison. Finally, the paper presents a detailed well-towheels (WTW) analysis from an energy-efficiency standpoint. The most important part of this analysis focuses on the effect of usage of various charging levels and charger topologies on the all-important plug-to-battery (P2B) energy-efficiency within the overall context of WTW energy cycle efficiency.
