MICROGRID DESIGN FOR EV FAST CHARGING STATION

The utilization of range of electric vehicles is increases rapidly and still in some areas it is limited due to more charging times. This can be improved by providing fast charging conditions that enable to charge a vehicle in less time. To maintain this fast charging conditions an efficient, compact size dc-dc converter with high power output is required. This paper proposes an interleaved dc-dc power converter to meet the above requirements. The proposed interleaved multi-phase converter, which is part of fast charging stations, has capable to charge the electric vehicle in less than 3hours time. To achieve high power density, ripple reduction on the output current and to improve the efficiency of converter a space vector modulation technique is applied. The operation of interleaved converter is analyzed in theoretically. Simulation analysis of proposed interleaved power converter shows the good behavior of converter, and charging conditions of various electric vehicle systems.
