The feasibility and performance of a battery charger for PHEV application using back to back (B2B) converter in a utility connected micro-grid has been investigated in this paper. A structure has been proposed involving three parts: an AC micro-grid. in which the load is fed from the DG source. a battery charger. in which the bi-directional DC DC converter is used. and main grid. The system infrastructure and operational principles are illustrated. The best controllers have been utilized to achieve better performances in V2M. V2G. G2V. M2V modes. In principle. the proposed scheme is very flexible and reliable. particularly for sensitive loads. The excellent performance of the proposed structure has been confirmed through extensive simulations on MATLAB SIMULINK for various operating conditions.
