   Design and Analysis of a Three-Phase Single-Stage AC-DC Converter with Series Resonant Tank for Electric Vehicle Charging Stations
By Mohammad RAMEZANI, Majid PAHLEVANI, Praveen JAIN [View]
[Download]

Abstract: This paper presents an analysis and design of a three-phase single-stage ac-dc converter with an LCresonant tank for use in the charging infrastructure for electric vehicles (EVs). The analyzed converter simplifies the power conversion process by reducing the number of components, enhancing both the system reliability and the efficiency. The operation of the converter is modeled and different modes of operation are presented. The introduced single-stage converter achieves zero voltage switching (ZVS), to minimize power losses and to optimize system performance. A prototype is designed and implemented, achieving 95.9\% efficiency with low input current total harmonic distortion (THD) and output voltage ripple utilizing small non-electrolyte capacitors. The simulation and experimental results validate the design and control scheme, showing the effectiveness of the proposed approach for modern EV charging stations.

   Design and Evaluation of Single-Active Bridge Configurations for Optimal Megawatt Charging Systems

Abstract: The increasing demand for high-performance isolated DC-DC converters is particularlyevident in the domains of charging infrastructure and electromobility. Among various converter topologies, the Single-Active Bridge (SAB) stands out as a preferred choice for applications requiring unidirectional power flow. This preference is driven by the SAB's inherent simplicity, robustness, and ease of control. The paper explores multiple configurations of the SAB architecture. A prototype is developed to validate the features and the design procedures presented in this paper. This paper summarizes testing and analysis, to evaluate the performance of each configuration to identify the optimal design for an efficient and reliable high-power charging system. The results offer valuable insights for developing advanced MCS solutions, ensuring robust and efficient energy transfer in high-demand scenarios. Ultimately the SAB configuration is loaded at 88 \% of the nominal load and the results are showcased.

   Single-phase single-stage bidirectional PFC converter utilizing monolithic GaN bidirectional switches
By Jan SITNIK, Matthias J. KASPER [View]
[Download]

Abstract: This article presents a comprehensive study on a bidirectional, single-phase, single-stage converter for Electric Vehicle (EV) charging applications. A converter topology providing galvanic insulation between the grid and the battery with Power Factor Correction (PFC) capabilities has been proposed. By utilizing new GaN transistors with bidirectional voltage blocking capabilities, the proposed converter topology allows for a reduction in the number of transistors, leading to a significant simplification of the converter in comparison to other state-of-the-art solutions. The system is successfully validated in a simulation study.

   Study of 3-Phase Embedded Charger for Vehicle-to-Home (V2H) Under Unbalanced Load Conditions
By Elie FAYAD, Antoine BRUYERE, François GRUSON [View]
[Download]

Abstract: This paper provides a comprehensive examination of various Vehicle-to-Everything (V2X) scenarios, emphasising on those that pose significant challenges. A focus is given to the Vehicle-to-Load/Home (V2L/H) scenario, where a three-phase embedded charger is tasked with powering a single-phase load. In this context, it is crucial to properly manage the load's neutral to ensure the voltages delivered by the charger remain balanced. The paper delves into two potential methods for neutral connection, elucidating the implications each method has on the power electronics involved.
