本論文主旨為整合串聯諧振轉換器之變壓器與諧振電感的研製與探討。由於諧振電路中含有多種磁性元件，即使將切換頻率提升以縮小體積，磁性元件仍佔有一定的使用空間。因此本文對變壓器進行分析與研究，在提高切換頻率的同時，進一步減少磁性元件數量縮小了電路佔用體積，並降低磁性元件中導線因高頻磁交鏈所產生之交流銅損。最終透過調配變壓器磁通耦合方式達到諧振電感與變壓器整合，並採用印刷電路板繞線(Printed Circuit Board Winding, PCB Winding)取代傳統繞線。利用PCB設計的便利性進行交錯繞製，並選擇最小磁動勢之排列組合，進而降低變壓器之交流銅損，且提升繞組繞製之精度。最後實作出輸入電壓770 V、輸出電壓770 V、輸出功率6 kW、電路操作頻率300 kHz、諧振頻率300 kHz與最高效率為96.5%的全橋串聯諧振轉換器電路。

The thesis focuses on design and implementation of integrated inductor with transformer for a series resonant converter. Because of many magnetic elements in the resonant converter, the magnetic elements still hold a certain space, even if the switching frequency has been increased in order to reduce the volume. Therefore, the thesis analyzes and studies the transformer. While increasing the switching frequency, the circuit footprint and the number of magnetic components are reduced, and the AC copper loss in the magnetic components is also reduced. By adjusting the magnetic flux coupling, integrating transformer is achieved and using printed circuit board winding to replace traditional winding. The transformer reduces the ac copper loss and improves the accuracy of winding, by using the convenience of pcb design for interlaced winding and selected the combination of the smallest magnetomotive force. In the end, the series resonant converter is implemented, and the input voltage is 770 V, the output voltage is 770 V, the output power is 6 kW, the operation frequency is 300 kHz, the resonant frequency is 300 kHz, and the efficiency is 96.5%.
