Finding effective solutions to enhance the process of electric vehicles’ charging is the main subject of numerous studies. In this paper, a novel bidirectional multiport rectifier has been presented which can be used as a wall-box converter that is installed in the parking lot of smart buildings and is able to provide DC-link for local DC loads such as DC home appliances and charge connected EV, simultaneously. The proposed converter is capable of working in G۲H/G۲VH/V۲H/V۲G modes which enables the utility grid and costumer to use the EV as a mobile power source and reactive power compensator. A control method is also presented which enables the converter to control active and reactive power according to the smart grid or customer processed commands. In order to validate features of the proposed converter, it is simulated in MATLAB/SIMULINK and results are analyzed. A reduced-scale experimental setup of the proposed converter is built and tested and experimental results confirm simulation ones.
