        abstract = {With the increased use of electric vehicles (EVs) in recent years, there has been an increasing demand for an effective and reliable charging system that will ensure minimum impact on the electricity grid. The on-board charger (OBC) acts as a converter between the alternating current from the grid to the direct current required to charge the battery of the electric vehicle. Most existing chargers make use of diode bridge rectifiers coupled with DC-DC converters. Such chargers are inexpensive and easy to construct but have several disadvantages including low power factor, high total harmonic distortion and poor efficiency of power utilization which causes degradation of power quality.
This paper proposes an Active Front-End (AFE) controlled on-board charger for electric vehicle applications to get around these problems. The suggested system uses a three-phase Voltage Source Converter (VSC) with Insulated Gate Bipolar Transistors (IGBTs) and an RL input filter to cut down on harmonics. To control the DC-link voltage and shape the input current, a closed-loop control strategy that uses dq-axis transformation, Phase-Locked Loop (PLL), and Proportional-Integral (PI) controllers is used.
Simulation and analysis of the proposed system have been carried out using MATLAB/Simulink. It is observed that the proposed system performs satisfactorily by providing a power factor of nearly unity and reducing THD considerably, along with ensuring a constant DC output voltage. Thus, the proposed system serves as a useful approach toward enhancing power quality in EV charging systems.},
