為了要降低在低電壓大電流輸出的情況下所造成的線路損耗及應力，全橋相移轉換器會以倍流電路作為輸出端的整流電路。相較於中心抽頭整流電路，倍流電路磁性元件的數量較多。為了減少磁性元件的數量以及避免漏感過大，造成過大的責任週期損失，本論文研製了一種新型倍流電路的磁性元件整合方式。改變繞線方式以解決既有磁性元件整合方式的缺點，有效的改善了漏感過大的問題並且達到耦合電感降低輸出電流漣波的優勢，以及相同的倍流整流效果。

In order to reduce the line power dissipation and wire stress, by adopted full-bridge phase-shifted converter with current doubler as rectification circuit in secondary side when converter’s output in a low voltage and high current condition. Compared with the conventional center-tap rectification circuit, the current doubler has more magnetics. This thesis proposes a new kind of current doubler structure with integrated magnetics to decrease the number of magnetics and prevent from the large leakage inductor which may cause large duty cycle loss. The proposed structure solves the problem of the large leakage inductance by changing winding method. The new structure also has the coupling inductor to reduce output current ripple, which has the same current rectification result compare to the conventional current doubler.
