The switching sequence of a phase-shifted zero-voltage-transition (PS-ZVT) full bridge converter circuit is alternated between two modes by periodically reversing the switching sequence for diagonally opposed switching devices of the bridge. Over a period of operation, each of the switching devices periodically conduct the entire free-wheeling current that occurs during load current reversal transitions so as to balance their average power dissipation and reduce the overall power dissipation of the converter circuit.
