“…The conventional EV charger consists of a diode bridge rectifier and has adverse power quality issues due to nonlinear input (Kushwaha and Singh, 2020). A two-stage AC-DC converter prefers better PQ in an EV charger since it has some limitations that the additional switching circuit and control circuitry (Kushwaha and Singh, 2019). A front stage is a rectifier circuit with a power factor correction (PFC) boost converter to attain a high-power factor and less harmonic distortion (Mc Donald and Lough, 2021).…”

Transport is a vital sector for achieving sustainable development. The evolution of the electric vehicle is subject to the charging time, accessibility, and facility. On-board chargers are broadly used in the battery-electric and plug-in-electric fleets due to their easy installation and low cost. Also, it must be powerful and extremely efficient because of the constrained interior area and quick charging times. The minimization of hardware requirements and ease of interconnection problems are benefits of unidirectional charging. This review article presents an overview of charging levels, standards of chargers, and various topologies. On-board chargers pose a higher-power rating that reduces the anxiety of charging time and improves the charging facility on level-1 and level-2 grid supply. Unidirectional chargers reduce the charger size while other two-stage chargers pose a higher charging rate with various topologies. Finally, emerging charging trends in off-board charging, inductive charging, technology about vehicle-to-grid, wide-bandgap devices, and application of renewable energy uses are addressed.

“…Power factor correction is an important issue to which the converter addresses by using a boost converter as the first stage, then a high-frequency inverter in the second stage connected to a transformer. A full-bridge converter is connected to the transformer secondary to get a DC output proposed in [3,4]. The major disadvantage of this converter is the same as discussed in [1], a huge number of switches.…”

“…The converter work with an input voltage of 750 Vdc to achieve a variable output voltage between 300 V-600 Vdc. None of the converters discussed in [1][2][3][4][5][6] can be used as first stage power conversion preceded by a renewable energy source because of the huge switching losses and inadequate gain ratio. Whereas maintaining a high voltage at the converter end will help to minimize the conductor size [7] in PHEV charging system.…”

Energy transformation by power electronic converters is not feasible without the efficient use of renewable energy. The article tries to extend the use of renewable energy to PHEV battery charging. In PHEV, the battery is one of the major sources of stored energy. The converter used for charging these batteries is of crucial concern. The paper addresses various challenges in designing a DC to DC converter for battery charging in DC bus. An optimized converter is designed to work with renewable energy sources to accomplish a high boost ratio, low input current ripple, low output voltage ripple, high power efficiency, and high power density. A combination of two interleaved boost converters is effectively used with the overlap time switching to achieve a high voltage boost ratio in forming the DC bus. Transformer isolation is used to increase reliability and boost ratio further. The secondary side employs a series-connected voltage doubler. The converter boosts an input voltage of 24 V to a range of 300-400 V. Simulation results have been obtained for a 300 W system. Simulation results are validated by a prototype implementation for a 250 W system. The converter is studied and analyzed for steady-state and transient state characteristics and the power efficiency obtained is 92.9%.

This paper proposes a three-port Zeta-KY dc-dc converter which is fed with hybrid sources like photovoltaic (PV) cells and batteries. The converter proposed here is a multi-input single-output (MISO) structure which harnesses the benefits of Zeta and KY converters. The combination of these converters is highly advantageous since the Zeta converter provides lesser output voltage ripples with high gain and the KY converter topology suits well for withstanding load transients. The KY converter used in this research work is subjected to a topological change to facilitate bidirectional power flow. The bidirectional flow is essential to save the excess power in PV source in batteries during low load conditions. This novel multiport topology with bidirectional facility is first of its kind and has not been discussed earlier in the research arena. In the proposed work, two control algorithms are developed and deployed: the first one ensures the maximum power extraction from the PV and the second one maintains constant dc bus voltage and manages bidirectional power flow. MATLAB Simulink and hardware prototype of the proposed system has been realized for a 72 V dc bus and a 500 W electric vehicular drive. The simulation and experimental results reveal that the proposed system is viable for medium power electric shuttle applications. The proposed system is subjected to various test cases and it is observed that the source and load intermittencies are catered very well by the proposed three port Zeta-KY converter. The developed multiport converter is feasible for renewable energy applications.
