摘要: This paper presents a new soft switching dc-to-dc converter that employs two separate transformers. Unlike previous topologies where transformers are used as functional substitute for one large transformer, the proposed utilizes its key operational components. The achieves high conversion efficiency by eliminating or minimizing and conduction losses, while retaining all benefits of using small low-profile instead transformer. operation performance demonstrated with an experimental delivers 3.3V/20A output from 44–52V input at maximum 94 %.
