【 摘 要 】

The electric vehicles (EVs) have gained popularity over recent years due to the stringent environmental standards on greenhouse emission and the scarcity of fossil fuels. The increased demand for plug in EVs has necessitated grid integrated bidirectional EV battery charging systems. These charging stations deployed near the parking lots, shopping malls or industries can make the EVs suitable for long-distance runs. Moreover, the off-board charging methods with grid integration and proper communication interfaces can utilise the EV to enhance demand side management. This study proposes a multifunctional, grid integrated, bidirectional charger with a single feedback loop controller. Along with the battery charge or discharge control at unity power factor operation, the system can act as an active power filter for the non-linear and reactive loads connected to the point of common coupling. Also, the bidirectional AC/DC converter is operated with reduced switching adaptive hysteresis current controller to assure high efficiency. Analysis of various modes of operation of the system is done using MATLAB/Simulink and the prototype of the low power setup is done with FPGA to validate the concepts.
