Abstract:	本篇論文主要研製一適用於個人電腦之300 瓦電源供應器，輸出規格如下：12V/16 A、5V/14 A、3.3V/13A、-12V/100mA 與一組待機電源5V/2A。電源模組中使用交錯式邊界模式功率因數修正電路為前置穩壓器，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 轉換器電路架構則為半橋式串聯諧振轉換器，配合零電壓切換減少一次側切換損耗與同步整流技術減少二次側導通損。兩組同步降壓型轉換器提供 12V 電壓降壓為5V 與3.3V。所研製之電源供應器具有個人電腦電源監控機制，以提供電源模組之安全保護。並以返馳式轉換器架構，提供待機與輔助電源。雛型電路的實驗測量結果，驗證了本論文所研究的電源架構與控制方法的可行性，且符合能源之星要求的規範。 The main purpose of this thesis is to study and implement a 300 W high efficiency PC power supply. The output specifications for the developed power supply are as follows: 12V/16A, 5V/14A, 3.3V/13A, -12V/100mA, and one set of standby power with 5V/2A output. An interleaved transition-mode power factor corrector (PFC) is used as the pre-regulator for raising efficiency, improving the input power factor (PF) and reducing the total harmonic distortion (THD) of the input current. A half-bridge series resonant converter (SRC) with synchronous rectification (SR) is adopted as the DC-DC conversion stage. Switching losses on the primary switches and conduction losses on the secondary rectifier can be significantly reduced. Two synchronous buck converters are implemented to step down 12V bus voltage for 5V and 3.3V low-voltage outputs. A PC power supply supervisor is used in the developed power supply to provide the protection functions. A Flyback converter is designed to implement the standby and auxiliary power supplies. Experimental results of a laboratory prototype are shown to verify the feasibility of the developed topology and control schemes. The prototype can substantially satisfy the ENERGY STAR computer program.
