全橋相移轉換器一般會外加諧振電感來讓電路在輕載時達成零電壓切換，因此電路當中的磁性元件包含了諧振電感、變壓器與輸出電感。然而這些磁性元件佔了大部分的體積空間，間接降低整體的功率密度。本論文主旨為研究如何利用鐵芯整合技術，將全橋相移電路當中的三種磁性元件整合至同一個鐵芯裡。藉由分析電路各個動作區間的交、直流磁通來求得各磁柱的磁通密度以避免鐵芯飽和。並且計算鐵芯整合後的等效區間電感以得知輸出電流漣波大小；除此之外，利用調整一、二次側線圈彼此之間的距離來調整漏感大小，以取代傳統全橋相移所外加的諧振電感。最後利用鐵芯整合技術實現一台輸入電壓380 V、輸出電壓12 V且輸出功率500 W的中心抽頭式全橋相移轉換器，將諧振電感、變壓器與輸出電感三種磁性元件整合至同一個鐵芯裡，藉此減少電路中的磁性元件數目。

Full-bridge phase-shifted converter sometimes adds external resonant inductor to achieve zero-voltage switching during light load condition. The magnetic components in the circuit include resonant inductor, transformer and output inductor. However, these magnetic components occupy a lot of space in the circuit which cause low power density. The thesis analyzes the integration of magnetic component which integrate these three magnetic components into one core. To derive the flux density and output ripple current, the thesis calculates the DC flux, AC flux and equivalent inductance during operation interval. By adjusting the distance between primary side winding and secondary side winding, the leakage inductor can be used to replace the resonant inductor. Finally, a 500 W full-bridge phase-shifted converter with 380 V input voltage, and 12 V output voltage is implemented by using integrated magnetic technology. Therefore, the resonant inductor, transformer and output inductor can be integrated into one core which can decrease the number of magnetic components in the circuit.
