基于軟開關技術的PWM開關電源研究

摘要：介紹一種全橋移相PWM開關電源，簡述其工作原理，討論了實現軟開關的條件以及諧振電感的問題，給出了輸出電壓和電流的檢測電路，并用MATLAB進行仿真，給出了仿真結果。 敘詞：軟開關；全橋移相；仿真 Abstract：This paper introduces a full-bridge Phase-Shift ZVS PWM DC/DC converter. An overview of this soft switch technique is presented including numerous design equations and associated voltage, current and timing waveforms supporting this technique. Some of control circuitry areas are given. At last a simulation with MATLAB of this converter will be provided and the results are included. Keyword：soft-switch, PS-FB, simulation
