A new three port bidirectional AC-DC converter is proposed in this paper for battery energy storage applications. Here, the charging and discharging of the batteries is done by both direct DC port and through bidirectional DC-DC converters and thereby reducing the power processed by DC-DC converter and hence reducing the losses. The efficiency is further increased by reducing the number of switches in direct DC port as the losses are reduced. The proposed converter is tested in both forward and reverse modes with supply and load connected on AC side terminals respectively. The efficiency graphs are drawn and compared based on simulation results. The model is developed and simulated in MATLAB/Simulink software package.
