倍流整流在低压大电流开关电源中的应用

摘要

在隔离型低压大电流输出的DC/DC变换器中，同步整流电路中存在着纹波电流大的问题。针对此问题，提出了倍流同步整流电路，与传统的整流电路相比，大大减小了纹波电流。通过实验验证了该方案的有效性和优越性。%In this paper, the merits and limitations of current -doubler rectifier are analyzed and synthesized. The current-doubler rectifier is compared with the other second-side rectifier. The conclu-sion has been drawn that the current-doubler rectifier is suitable for the low-voltage high-current out-put DC-DC converter.
