本篇論文主要研製一符合能源之星規範的240瓦小型化桌上型個人電腦電源供應器,其規格如下:+12 V/20 A (Vmain)、12 V/1.3 A (Vsb)。前置穩壓器採用邊界導通模式功率因數修正器,以提高轉換效率與功率因數,並減少輸入電流的總諧波失真率。DC-DC轉換器架構選用半橋式串聯諧振轉換器提供12 V輸出,其零電壓切換特性可減少變壓器一次側切換損耗,並使用同步整流技術減少二次側導通損。最後設計一返馳式轉換器,提供待機與輔助電源。
基於本文研究論述,設計實現一個人電腦電源供應器,實際量測結果驗證了所研究的可行性,並且符合能源之星之規範。
In this thesis, a 240-watt power supply for small form-factor personal computer is designed for satisfying the Engergy Star requirenents. The output specifications of the developed power supply are: +12 V/20 A (Vmain), and 12 V/1.3 A (Vsb). Boundary conduction mode power factor corrector (BCM PFC) is adopted as the pre-regulator to enhance the conversion efficiency, raise input power factor and reduce input current harmonics. The DC-DC converter is implemented by using a half-bridge series resonant converter (SRC) to provide the 12-V output. The inherent zero-voltage switching feature reduces the switching loss of primary power switches. Synchronous rectification (SR) technology is used to eliminate the secondary conduction losses. A flyback converter is designed to provide standby and auxiliary powers. Experimental results of a prototype circuit are shown to verify the feasibility of the studied power supply system. Both the conversion efficiency and power factory meet the requirements of Energy Star specifications.
