Dual Active Bridge topology gain

[Techman_7]

The gain equation of dual active bridge is = N *(Vout / Vin), where N = Transformer primary to secondary turn ratio.

Is it correct equation?
Below is the DAB schematic.

 

[Easy peasy]

the gain depends on the effective PWM of each side and their phase relationship x the transformer turns ratio

it is possible to operate in a boost mode by building up the current in l and then changing state on the receiving side.

Read up on leading and lagging phase shift for bi-directional operation, also on the phase difference between legs on the LHS ( for example ) which can vary from in phase to 180 deg out of phase ( usually full power )

lots to learn here ...

Can you please point me to a paper that describes this?
