摘要：本文結合不對稱半橋倍流整流變換器，介紹了兩個電感與一個變壓器的集成。通過集成磁件的變換，給出了磁集成的兩種方式，即正向耦合方式與反向耦合方式。理論分析和PSpice仿真驗證了反向耦合方式在磁芯體積和功率損耗減小方面具有優勢，在變換器效率上反向耦合方式也明顯高于正向耦合方式。 敘詞：磁集成技術；倍流整流；變換器 Abstract：The integration of two inductors and one transformer for asymmetrical half bridge current doubler rectifier converter is introduced in this paper . Two modes of integrated magnetics , positive direction and negative direction coupling mode , are given by intergrated magnetics changing .Theory analysis and PSpice simulation validate that there is an advantage of reductions in the size and power losses of magnetic core for negative direction coupling mode . Efficiency comparison is given which shows a great improvement by using negative direction coupling mode . Keyword：integrated magnetics; current doubler rectifier;converter
