| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 105 === 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.
