| 摘 要： | 针对传统反激电路的一些不足,将交错并联技术用于双管反激电路中,具有工作频率高,输出纹波小,功率等级高等优点。本文分析了两路交错并联双管反激变流器的工作模式,采用开关平均法建立了电流断续模式(DCM)下的变流器小信号模型。详细论述了采用电流峰值控制和光耦隔离系统时,其反馈补偿回路的设计方法。最后通过一台100W实验样机,验证了工作模式分析和参数设计的正确性。

| Abstract: | Aiming at overcoming the disadvantages of the traditional flyback converter,this paper introduces the technique of interleaved power conversion into the double-transistor flyback circuit.It achieves the benefits such as raising the working frequency,smoothing the output voltage ripple,increasing power level.The operation modes of the interleaved double-transistor flyback converter have been analyzed.The DCM small signal AC model using the averaged switch method has been built up.The design of the feedback compensator using the peak current control method and opto-coupler insulation is analyzed in details.A 100W prototype is built to verify the operation principle and parameter design. |
