The existence and successive development in the phenomena of EV relies equally on the development of charging infrastructure. This proposed research integrates the operative differences of various converter configurations suitable for EV charging under diverse working conditions. Analysis and the assessment of these power converters are portrayed with respect to the power output, active and passive components and other reliable factors respectively.In addition, evaluations of the converters are presented with their topological design and supporting architecture for EV charging stations. Multidevice interleaved bidirectional converter is observed as the most appropriate interfacing converter for the EVs on account of its low output voltage and current ripples. This article explicitly addresses the characteristics and categories of power converter for EVs powertrain and the ideas are validated through the real time PSACAD/EMTDC simulation tool. Keywords —Electric vehicle; Charging station; Clean and green energy; Power converters; Multi-device interleaved DC-DC converter; Powertrain; PSCAD simulation I. INT RODUCT ION Emission free vehicles are gradually turns out to be an arising innovation in the transportation belt of electric power sector in the recent years [1]. Owing to the concept of zero emission and perhaps the participation from green energy has successfully prompted the way to explore the research advancement in this growing sector eventually. Several proposals have been initiated by the private and public bodies across the globe (such as IEEE) to promote awareness in the deployment of alternate energy vehicles and attractive frameworks are introduced by the governments to electrify the commercial automobiles within the stipulated time [2]. The significant development in the EV market has sorted out the existing issues and certainly brought innovations in charging the energy storage system (like fast and ultra-fast charging). Steady potential for the load (EVs) can be extracted from the renewable sources with the assistance of DC-DC converters. Isolated and non-isolated are the broader classifications of DC-DC converters preferred in most applications. Intricate design and multiple component counts are the downsides of isolated configuration. On the other hand, non-isolated converters are widely preferred in various applications owing to its improved efficiency and suitable for charging applications too. Energy storage is the crucial part of the EVs wherein the charging time, lifespan and its cost decides the market attraction. Additionally, these are the factor that tends to set barriers owing to numerous complications. Thereby, it is understood that the novel research and innovations of various charging models are the key factors in EV advancement. Structural design of EV charging network is portrayed in Fig. 1.
