本文研製一台以整合型磁性元件實現全橋相移直流-直流轉換器。全橋相移式轉換器具有零電壓切換的特性，可提升轉換器效率。本文利用磁性材料幾何結構，將全橋相移轉換器所使用的變壓器及濾波電感，整合成單一磁性元件，以其縮小變壓器之體積及高度。本文介紹全橋相移轉換器之動作原理，分析及製作整合型磁性元件。最後實作出一台輸入直流電壓為400 V、輸出直流電壓為12 V、滿載電流30 A、最大輸出功率為360 W之轉換器。

This thesis is concerned with the realization of a phase-shifted full-bridge dc-dc converter with Integrated Magnetics. A phase-shifted full-bridge converter with zero-voltage switching can be effectively improved. The geometric structure of magnetic materials is used to integrated transformers and inductors of phase-shifted full-bridge dc-dc power converters into a single magnetic component to reduce size and height. The thesis presents the design and implementation of the phase-shifted full-bridge dc-dc converter with integrated transformer and inductor as the control circuits. Finally, a 360 W laboratory prototype for phase-shifted full-bridge dc-dc converter with specification of 400 V input voltage, 12 V output voltage and 30 A output current was implemented.
