    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
    少輸入電流的總諧波失真率。DC-DC 轉換器電路架構則為半
    12V 電壓降壓為5V 與3.3V。所研製之電源供應器具有個人電
    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.
