A soft-switching bidirectional DC/DC converter fed PMDC motor with a LC series resonant circuit is proposed. The proposed converter has been obtained by adding LC series resonant tank in the conventional bidirectional DC/DC converter. The conventional type DC/DC converter incorporating the old switching techniques would raises the switching losses and voltage stresses on the devices. The above drawback is rectified with the help of soft switching techniques. The proposed topology performs soft switching at both buck and boost operations. Through the theoretical boost and buck mode analysis, Zero Voltage Switching (ZVS) operation is explained.
