Abstract:	本論文介紹串聯諧振式轉換器(Series Resonant Converter，簡稱SRC)與LLC型式串聯諧振式轉換器(LLC-Type Series Resonant Converter，簡稱LLC SRC)的理論基礎及動作狀態分析，並分析各動作區間之等效電路，與推導串聯諧振轉換器各區間動作之數學模型。本論文同時針對全橋LLC 串聯諧振式轉換器進行電路分析，研製一台雙變壓器全橋LLC 形式串聯諧振轉換器，此架構之優點為變壓器可均分輸出負載電流，分散變壓器體積，並易於實現電源供應器高功率密度之要求，藉由設定諧振頻率及特性阻抗，可計算出各元件之値。最後實作一台輸出規格為12V/42A 之雙變壓器全橋LLC 串聯諧振式轉換器，除了將實測結果和理論相互印證之外，並研擬未來研究方向。 This thesis focuses on the analysis of basic theories and operating modes of a series resonant converter (SRC) and an LLC-type SRC. The equivalent circuits and their mathematical models for each operation modes are also discussed. The main focus is on analyzing a full-bridge LLC-type SRC. A two-transformer full-bridge LLC-type SRC prototype is implemented. The advantages of this topology are the inherent load current sharing, reduced transformer sizes, and feasible for high power density requirement. From the specified resonant frequency and characteristics impedance, the circuit components can be calculated. Lastly, a two-transformer LLC-type SRC with an output voltage of 12 V and an output current of 42 A is realized. Theoretical analyses are verified with the experimental results. Also future works for this research are included.
