Abstract For the different characteristics of non-resonant and resonant isolated bidirectional full
bridge DC-DC converter, a unified expression of power transmissions is derived from the two DC-DC
converters. The power transfer characteristics could be unified described through the power expression.
The problem of isolated bidirectional DC-DC converter is that the switching loss increases and the
converter efficiency declines with the forced turn-on or turn-off of switch devices in high frequency
situation. In this paper, to solve this problem, an isolated LC series resonant transformer full bridge
DC-DC converter is taken as research object, a phase-shift control strategy which could realize zero
voltage turn-on and decrease th
