Description: In this paper, a new method of integration between PV inverter system with utility grid for electric vehicle charging station based on the extended boost quasi-Z-source (q-ZSI) topology is proposed. The proposed system realizes a bidirectional power flow management between PV sources, energy storage unit and the utility grid. The extended boost q-ZSI is a most efficient topology that provides a single stage conversion for PV systems by providing low ratings for components, reduced number of components used, high input voltage gain, increased voltage boost property , reduced voltage stress across switches and simple control strategies .Its unique capability in single stage conversion  with improved voltage gain is used for voltage buck and boost function. A simulation model of the grid connected q-ZSI for electric vehicle charging station has been built in MATLAB/ SIMULINK. The hardware setup was developed and the results are validated.
