Abstract This paper presents a new dual switch forward DC/DC converter topology. The duty cycle can be more than 0.5 by resonant reset. In addition, soft switching operation is achieved for all switches of the presented converter by adding a saturable reactor . It means that the converter is very attractive for wide range input and high efficiency application. In this paper, the operation principle and characteristic of this converter are analysed in details. Finally, the advantages mentioned above are verified by a 250～400V input, 54V/5A output prototype.
