In this paper a 500 W (50 V@10 A) forward converter is presented, which is part of a battery charger. An auxiliary resonant circuit was added to the basic forward converter, implementing the zero-voltage-transition (ZVT) technique for the main switch. The switch employed by the auxiliary circuit operates under zero-current-switching (ZCS) conditions. The overall efficiency improvement goes from about 2% at light load, to about 5% at full load.
