A soft switching converter is presented with the advantages of wide zero‐voltage switching range, low primary conduction loss, less output inductance and power transfer within the whole switching cycle. Half‐bridge circuit is connected to the lagging‐leg power switches of full‐bridge converter to improve the soft switching load range. One positive rectified voltage is generated on the secondary side to reduce the primary current to zero during the freewheeling state. Therefore, the primary conduction loss is reduced. The performance of the proposed converter is verified by the experimental verifications with a 1.92 kW prototype.
