本文研製一台儀器用高功率雙組輸出轉換器，前級採用無橋式昇壓型功率因數修正器以達到高功率因數和低輸入電流諧波，且使用無橋技術減少損耗提高轉換效率。後級採用全橋串聯諧振轉換器，實現零電壓柔性切換，降低切換損。本文分析各級的電路工作原理與等效電路推導，再利用MATHCAD模擬軟體針對全橋串聯諧振轉換器，模擬品質因數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，以設計適合的功率及磁性元件。最後，實際設計一組電源供應器，在輸入265Vac的情況下，效率最高可達95%，並將量測結果與理論相互印證。

This thesis focuses on the study on High Power Dual-output Power Supply for Instrumentation Applications. A bridgeless boost power factor corrector (PFC) operated under continuous conduction mode (CCM) 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, K factor, characteristic impedance, and turns ratio on the voltage gain transfer function have been analyzed and discussed by using the MATHCAD software to design the magnetics for presented power converter.Satisfactory experimental results confirm the validity and feasibility of the adopted schemes. Potential future works are mentioned to further improve the power rating and conversion efficiency.
