The improved three switch-active clamp forward (3S-ACF) converter is proposed in this paper. The proposed converter has minimized switching loss on all switches of 3S-ACF converter by simple change of gate control scheme without any additional components. In addition, current stress of clamp diode can be significantly reduced. Though, all switches of the proposed converter have low voltage stress...
A conventional asymmetrical half-bridge (AHB) converter is widely used for dc–dc stage in low-to-medium power system. However, since the asymmetric operation of AHB converter causes the low efficiency over entire load condition, the conventional AHB converter is not usually considered for the candidate of server power system. In order to overcome the problems of the conventional AHB converter, a wide...
