Resonant Reset Soft Switching Dual Switch Forward DC/DC Converter

This paper presents a new topology named resonant reset soft switching dual switch forward DC/DC converter.Itmaintains tow voltage stress and employs resonant reset scheme to solve the problem in the normal main switches that dutycycle cannot be more than 0.5.In addition,utilizing the features of resonant reset scheme and a saturation inductance insecondary side,the proposed topology achieves soft switching for all switches.Therefore,it is very attractive for high input,wide range and high efficiency applications.The operation principle and characteristic of this topology and the realization anddesign method of the soft switching are discussed in the paper in details.Finally,the advantages mentioned above aredemonstrated by experimental results.
