Comparison between a novel zero-switching-loss topology and two existing zero-current-transition topologies

In this paper, two existing zero-current transition topologies are reviewed, and a novel zero-switching loss (ZSL) topology is introduced. Working principles for ZSL topology are discussed. With respect to loss, efficiency and electrical stress, this paper provides a comparison of three topologies under a DC/DC converter configuration in which bus voltage is 300 V and load current is 40 A.
