本論文之研究目的為研製AC 600 V高電壓輸入、具7 kW高功率輸出之電源供應器，電路採用兩級功率級架構，分別為交錯式功率因數修正器與開迴路全橋串聯諧振轉換器，搭配電磁干擾濾波器、保護電路與輔助電源完成整機架構。前級交錯式功率因數修正器為提高功率因數與降低輸入電流諧波；後級全橋串聯諧振轉換器為提高效率，實現零電壓與零電流切換技術。最後設計實作一台 7 kW電源供應器，並進行測試與分析實驗結果。

This thesis presents the study and implementation of a power supply with a input AC voltage of 600 Vrms and output power of 7 kW. A two-stage power converter topology consisting of an interleaved power factor corrector (PFC) and an open-loop controlled full-bridge series resonant convertor is adopted. The complete system incorporates the EMI filter, auxiliary power supplies, and protection circuits. The front-stage interleaved PFC helps improve the power factor and reduce the input current harmonics. The post-stage full-bridge series resonant converter can raise the conversion efficiency with zero-voltage switching (ZVS) and zero-current switching (ZCS) techniques. Finally, a 7-kW power converter is designed, implemented, and tested. Experimental results are measured and analyzed.
