This paper presens comparison beween phase-shif full-bridge converers wih noncoupled and coupled curren-doubler recifier. In high curren capabiliy and high sep-down volage conversion, a phase-shif full-bridge converer wih a convenional currendoubler recifier has he common limiaions of exremely low duy raio and high componen sresses. To overcome hese limiaions, a phase-shif full-bridge converer wih a noncoupled curren-doubler recifier (N) or a coupled curren-doubler recifier () is, respecively, proposed and implemened. In his sudy, performance analysis and efficiency obained from a 500 W phase-shif full-bridge converer wih wo improved curren-doubler recifiers are presened and compared. From heir prooypes, experimenal resuls have verified ha he phase-shif full-bridge converer wih N has opimal duy raio, lower componen sresses, and oupu curren ripple. In componen coun and efficiency comparison, has fewer componens and higher efficiency a full load condiion. For small size and high efficiency requiremens, is relaively suiable for high sepdown volage and high efficiency applicaions. 1. Inroducion In a decenralized power sysem, he fron end ac/dc converer is generally composed of wo sages, in which one is a power facor correcion (PF) and he oher is an inermediae dc/dc converer, as shown in Figure 1. Mos of PF circuis adop a boos converer [1], and an inermediae converer is usually wih an isolaed version []. Using a boos converer can achieve a uniy power facory, and using an isolaed converer can provide galvanic isolaion and high oupu curren. In off-line applicaions, universal ac volage is always ino dc 400 V as a dc bus by boos converers, and an inermediae dc/dc converer convers i o a low volage bus of 4 V dc or 1 V dc. Therefore, for high oupu curren and low oupu volage applicaions, an isolaed dc/dc converer is usually required. To achieve low oupu volage, high oupu curren, and high efficiency, a phase-shif full-bridge converer wih convenional curren-doubler recifier is widely used in mediumhigh power condiion, as shown in Figure [3]. Neverheless, i sill has several limiaions. For example, for high sepdown volage conversion, i requires a ransformer wih high urns raio or i has o reduce he duy raio of he swiches. high urns raio will resul in high duy loss and low conversion efficiency, while a low duy raio will increase inpu peak curren and componen sress [4]. The oher limiaion is ha is large exernal resonan inducor will induce a large circulaion curren, which will flow hrough he primary winding of he ransformer and he swiches during a freewheeling inerval. s a resul, conducion loss in he swiches and copper loss in he ransformer are significan. To release he above-menioned limiaions of he convenional full-bridge converer wih curren-doubler, many approaches have been conduced [3 7]. However, heir high sep-down volage raio sill resul in exremely low duy raio, which will induce high peak curren hrough he secondary winding of he isolaion ransformer and oupu filer inducors, increasing copper loss and componen sresses [8 1]. To solve he above-menioned problem, he phase-shif full-bridge converer wih N or is proposed,

They can alleviae he drawbacks of exremely low duy raio and high componen sresses.
