The voltage transfer ratio, m, for a dual-active bridge is given by Equation 17, where N is the primary-to-secondary turns ratio.
The required leakage inductor for phase shift is calculated from Equation 18.
The required leakage inductance calculated from this formula is around 30uH which approximately matches the simulation results for phase shift against inductance.
