Studying the principle of operation of the DC/DC converter "Dual active bridge", I'm trying to understand what task the inductor (Ls) shown in the diagram performs. The transformer galvanically isolates and regulate the voltage in output side.
I didn't find much information on this inductor. There are thoughts that it accumulates energy, but I'm not entirely sure about this.
Question: what tasks does this inductor perform?
P.S. Maybe someone knows some good articles on this converter?
