“…Additionally, non-isolated topologies are employed, offering the features like soft-switching capability, control simplicity, and a narrow voltage range. Examples include buck-boost converters with varying numbers of implemented switches [223], [224], and multi-phase interleaved converters [225]. Recently, resonant and multi-port DC-DC converters have emerged as promising technologies for widevoltage-range applications, offering benefits such as low EMI, high efficiency, frequent operation, and compact size [112], [226]- [229].…”

Electric vehicles (EVs) are becoming more popular worldwide due to environmental concerns, fuel security, and price volatility. The performance of EVs relies on the energy stored in their batteries, which can be charged using either AC (slow) or DC (fast) chargers. Additionally, EVs can also be used as mobile power storage devices using vehicle-to-grid (V2G) technology. Power electronic converters (PECs) have a constructive role in EV applications, both in charging EVs and in V2G. Hence, this paper comprehensively investigates the state of the art of EV charging topologies and PEC solutions for EV applications. It examines PECs from the point of view of their classifications, configurations, control approaches, and future research prospects and their impacts on power quality. These can be classified into various topologies: DC-DC converters, AC-DC converters, DC-AC converters, and AC-AC converters. To address the limitations of traditional DC-DC converters such as switching losses, size, and high-electromagnetic interference (EMI), resonant converters and multiport converters are being used in high-voltage EV applications. Additionally, power-train converters have been modified for high-efficiency and reliability in EV applications. This paper offers an overview of charging topologies, PECs, challenges with solutions, and future trends in the field of the EV charging station applications.

“…Bidirectional chargers increase the usability of electric vehicles by allowing energy transfer from vehicle to grid (V2G) or vehicle to home (V2H) as well as charging from grid to vehicle (G2V) [7,8]. In [9], topology and operation of an interleaved buckboost converter, which consists of a line frequency commutated unfolding bridge with low semiconductor losses and lower battery current ripple, are presented. The energy and power required for charging EV batteries may have an adverse impact on the distribution grid that can be minimized utilizing onboard EV battery chargers.…”

Extensive research has been ongoing in the field of Electric Vehicle (EV) chargers. This article addresses transfer of electric power from the grid to EV and from an EV to grid, a configuration of a single-phase charger system consists of bidirectional AC-DC converter integrated with bidirectional DC-DC converter. An artificial neural network (ANN) controller is employed for controlling the charging current and voltage. ANN model produces the required duty cycle to feed the maximum power under both Grid to Vehicle(G2V) mode and Vehicle to Grid (V2G) mode. The ANN is trained for the measured battery voltages and battery current to estimate the bidirectional converter's duty cycle. The implementation of the neural network is presented in this study, and simulation results are accomplished using Matlab/Simulink. The simulation findings support the effectiveness of the suggested control technique as well as its practicality. A comparative study is made to show the enhanced performance of the proposed controller than the conventional Proportional-Integral (PI) controller.

“…PI controllers are utilized in the BDC controller to reduce the error produced by the inductor currents [38]. An interleaved, nonisolated buck-boost BDC [64,65], illustrated in Figure 15b, offers reduced converter size and current ripple. In buck mode, S 1 and S 2 switches will turn on alternately to step down the DClink voltage.…”

With the evolution of the smart grid concept, the production of electric vehicles (EVs) is predicted to rise because of environmental concerns, technological advancements, and improvements in EV management. Vehicle‐to‐grid (V2G) is an enabling, realistic, and affordable technology to cope with a large number of EVs, increase energy sustainability, provide economical solutions, satisfy user‐side consumers, and facilitate power flow to the grid. Power electronics (PE) converters, particularly bidirectional power converters, are promising interfaces for V2G infrastructure because they determine the characteristics and functionalities of V2G. Therefore, this study provides an extensive review of the characteristics, technological aspects, and visions of V2G infrastructure. This review helps to identify the current state, most recent developments, and problems related to bidirectional interface topologies and control strategies in V2G infrastructure. It further examines the classification of chargers or dischargers based on numerous factors, including limitations and impacts. Furthermore, the benefits, challenges with possible mitigation solutions, and future outlooks in the implementation of V2G technology are discussed. This review is planned to serve as a reference for existing work in V2G frameworks, PE interfacing topologies, and control strategies, and to also facilitate a guideline for future work that can be implemented to flourish V2G technology.
