Grid Connected Single Step Bi-Directional Inverter for Battery Energy Storage System

The goal of this paper is to intend a grid-connected bidirectinal inverter for battery energy storage system which is built with many numbers of choppers and full-bridge inverter. The advantages of this GSB-inverter are low battery, dc-bus voltages, single-step power conversion, pulsating charging /discharging currents and individual power control of each battery module without any current sensor. Thusly the increase in a lifetime and more flexibility and the interleaved operation and be achieved. The simulation results will be present to make sure the performance of GSB-inverter.
