本論文主要研製一台2.4 kW寬輸入電壓範圍之雙組輸出330 V轉換器，前級採用無橋式CCM昇壓型功率因數修正器(PFC)，其電路實現了高功率因數和低輸入電流諧波及高轉換效率。後級採用全橋串聯諧振轉換器實現了ZVS零電壓柔性切換。全橋串聯諧振轉換器首先利用MATHCAD模擬軟體針對品質因數Q、K因子、特性阻抗Zo及圈數比n，分析與探討其轉移函數曲線。接著設計其適合的功率及元件及磁性元件。
在實作上以UCC28019及UCC25600，做為無橋式CCM昇壓型功率因數修正器(PFC)以及全橋串聯諧振轉換器控制IC，分別研製2.4 kW的電源轉換器並整機測試，且使用TNY278做為輔助電源的IC。經過了詳細的規劃，對於所設計的電源轉換器進行了設計與分析，並對於設計出來的2.4 kW轉換器進行實際測試，實驗結果證實，在輸入電壓160 V至264 V的情況下整體效率在89％以上。
實驗結果驗證了所採控制技術之正確性與可行性，同時也提及後續可能的研究方向，以期更為提高功率及效率。

This thesis focuses on the study and implementation of a 2.4 kW 330 V converter with dual-output and wide input voltage range. A bridgeless boost power factor corrector (PFC) technique is designed and implemented to achieve high power factor, low input current ripple and high efficiency. A full-bridge series resonant converter with zero voltage switching (ZVS) is used as the post-stage circuit. The influences of the quality factor (Q), K factor (K), characteristic impedance (Zo), and turn ratio (n) on the voltage gain transfer function have been analyzed and discussed by using the MATHCAD software to design the magnetics for appropriate power.
The 2.4 kW converter is implemented and an auxiliary power supply with TNY278 is adopted. According to the formulated design procedures, and has a whole test on 2.4 kW converter. The experimental results, when input voltage range is 160 V~264 V, the efficiency is higher than 89%.
Satisfactory experimental results confirm the validity and feasibility of the adopted schemes. Potential future works are mentioned to further to improve the power level and conversion efficiency.
