“…For resonant DC/DC converters, the wide range of input and output voltage cause low efficiency, because these converters only achieve the best efficiency when the switching frequency is the same as resonant frequency. A variable DC-link voltage of the PFC converter can mitigate this disadvantage, but the resonant tank needs to be carefully designed to cover that wide-voltage range [125], [126]. Moreover, compared to single controller of single-stage OBCs, some two-stage OBCs employ a separate controller for the PFC and DC/DC This work is licensed under a Creative Commons Attribution 4.0 License.…”

The fast development of electric vehicles (EVs) provides significant opportunities to further utilize clean energies in the automotive. On-board chargers (OBCs) are widely used in EVs because of their simple installation and low cost. Limited space in the vehicle and short charging time require an OBC to be power-dense and highly efficient. Moreover, the possibility for EVs to deliver power back to the grid has increased the interest in bidirectional power flow solutions in the automotive market. This paper presents a comprehensive overview and investigation on the state-of-the-art solutions of bidirectional OBCs. It reviews the current status, including architectures and configurations, smart operation modes, industry standards, major components, and commercially available products. A detailed overview of the promising topologies for bidirectional OBCs, including two-stage and single-stage structures, is provided. Future trends and challenges for topologies, wide bandgap technologies, thermal management, system integration, and wireless charging systems are also discussed in this paper.

With the growing popularity of electrified transportation across the world, there have been extensive reports of research involving plug-in electric vehicles (PEVs), electric vehicle charging facilities (EVCFs) and their integration to the main electric grid, besides sustainable energy resources for powering these vehicles. This study proffers a power factor corrected level-1 DC public green-charging infrastructure accompanied by an integrated control, for electric light motor vehicles, compliant with recently formulated Indian charging standards. Power factor correction of plug-in electric vehicle charging current, solar photo-voltaic grid integration and charging of energy storage system is achieved using control of bidirectional AC/DC converters. A firmware and user interface for multimode off-board DC charging, with green, fast and semi-fast charging modes are investigated. Intelligent control for fast charging is also presented to reduce its pernicious impact on the grid. The simulation and hardware results verify the prime performance objectives of improving the local power quality and renewable energy utilisation with multimode charging, in the Indian context. The effectiveness of the proposed infrastructure is further demonstrated by a simulated use case, where 30 PEVs are randomly charged, in various modes, at this EVCF during busy commute hours. 2 State-of-the-art This section presents the issues, latest research, and standards, both global and in the Indian context in the area of PEV charging infrastructure and its grid integration. 2.1 Power quality issues due to charging equipment In linear circuits, as voltage and currents are sinusoidal, the power quality issue arises from the displacement power factor. In nonlinear circuits, with non-sinusoidal currents, power quality issues arise from both displacement and distortion power factor [11]. Loads that draw non-sinusoidal current from the sinusoidal voltage source cause harmonics. Battery chargers, typically, are equipped with rectifiers at the input stage that cause current harmonics in the distribution system [12, 13]. Generally, lower priced models of chargers do not handle this requirement effectively. Saber et al. [14] propose a PFC scheme based on unidirectional, current-source active rectifier for charging PEVs. An on-board PFC scheme was also discussed in [15], in which the converters in the PEV are controlled to refine the power quality. However, this increases the complexity and weight of the on-board charger.
