In general, a DC/DC converter provides energy transfer from a source to a load in one direction. Today, bidirectional power transfer is needed in many applications that include battery based energy storage. Serving a compact solution for this problem is crucial in order to reduce the total size of the system where the physical size is a critical subject. Various types of bidirectional DC/DC converters are implemented for this purpose in literature. Highlighting the reasons, one of them is selected, proposed and simulated for a special double battery suited system which has a rated power of 1 kW. In order to compare efficiency performance of the switching strategy design for this topology; proposed in , with conventioal one throughout the whole operating points, simulations are realized at various operating conditions. Since proposed method is a software based solution, there will be no need for extra circuit components. With the results of this study, it is seen that the selected topology and applied modulation technique are suitable for bidirectional power flow and the power density can be increased with a software-only solution for this kind of applications.
