| 摘 要： | 随着数字控制芯片DSP/FPGA在模块电源中的广泛应用,其待机静态工作电流大、功耗高的问题也日益突出。采用传统的辅助电源方式难以满足设计要求。提出了一种同步整流Buck-flyback拓扑,分析了其工作原理,并推导了其稳态工作基本关系。通过构建实验样机平台,证明了理论分析的正确性。

| Abstract: | For the digital controller used more and more popular in the module power supply,its high standby quiescent current and power consumption make the traditional auxiliary power supply approach difficult to meet the design requirements.The proposed synchronous rectifier Buck-flyback(SR Buck-flyback) topology is analyzed.The steady state operation principles is given.The experimental results verify the correctness of the analysis. |
