Abstract:  
In this paper, a bidirectional DC-DC converter with high power density for energy storage application is proposed. The presented converter provides the possibility of power transfer in both directions only through adjusting phase shift angle. Zero voltage switching (ZVS) in both turn-on and turn-off moments of all switches is the major capability of the converter that makes it suitable for high power applications. ZVS of the converter is provided without any auxiliary devices. High frequency transformers are employed in the converter construction to match the converter’s two-side voltage. Moreover, transformer’s leakage inductance along with external auxiliary inductance acts as energy storage in a power transfer from one side of the converter to the other side. Operation principle of the converter in the steady state is analyzed, and, then, its dynamic model is derived. ZVS criteria of the proposed converter are studied, and finally the experimental measurement results of laboratory-scale prototype are presented.
