magnetic attraction

Based on the thorough investigation of the post - regulation and efficiency in multiple output switching - mode power supplies , an optimal combination topology for multiple output switching converter is presented in this thesis , which is consisted of forward converter with active clamp ( fac ) , synchronous rectification ( sr ) techniques and magnetic amplifier technique ( magamp ) 本文通過研究分析近年來多路輸出開關電源輔助輸出電壓調節和提高效率的方案,面對開關電源朝著輸出低電壓大電流方向發展的趨勢,提出多路輸出開關電源新的拓撲優化組合模式? ?有源鉗位正激變換器、同步整流技術、磁放大器。

With the stringent requirement of low output voltage and high output current , semiconductor diode is necessarily replaced by synchronous rectifier to minimum voltage drop . because the existed driving schemes can not drive srs properly , two novel driving schemes for synchronous rectifiers in magnetic amplifier post regulating circuit are proposed in this paper 已有的同步整流管驅動電路主要面對多路輸出的主輸出電路,而應用磁放大器調節的輔助輸出電路同步整流管的驅動,現有的方法存在磁放大器調節與同步整流管驅動的失配,降低了開關電源的效率。
