Design of PV fed Bidirectional Converter using PI Controller for EV Charging Station

Now a days the charging of electric vehicles (EV) is tough task in using the renewable resources. PV system is the better solution regarding this matter. This paper reflects, the charging of EV battery from the PV system using the control mechanism. Bidirectional DC-DC converter is deployed here to transform the power flow from solar system to EV battery system for the purpose of both charging and discharging of battery. The converter output is regulated by using PI controller and the operation of the bidirectional converter is running in both buck and boost mode by reversing the direction of power flow. The battery storage system is used to store the voltage while the weather conditions vary. Simulink results are shown and verified in MATLAB/Simulink platform.
