A new zero-voltage switching full-bridge dc-dc converter for battery charging is proposed in
this paper. The proposed isolated dc-dc converter is used for the dc-dc conversion stage of
the electric vehicle charger. The primary switches in dc-dc converter turn-on at zero voltage
over the battery-charging range with the help of passive auxiliary circuit. The diode clamping
circuit on the primary side minimizes the severity of voltage spikes across the secondary
rectifier diodes, which are commonly present in conventional full-bridge dc-dc converters …

A new zero voltage switching (ZVS) full-bridge DC-DC converter for traction battery charging
is proposed in this paper. The proposed isolated DC-DC converter is a part of AC-DC
converter in an electric vehicle charger. The main active switches in the converter turn-on at
zero voltage over full-load range with the help of passive auxiliary circuit. The diode
clamping circuit on the primary side eliminates the voltage spikes on the secondary rectifier
diodes which are commonly present in conventional full-bridge DC-DC converters. The main …
