摘要 分析了一种新颖的运用磁放大器作为后极调整技术的多路输出的正反激DC/DC变换器的工作原理。这种变换器可以利用电路的正激部分输出大功率,而用反激部分输出小功率。所以,该电路将正激变换器的高效率和反激变换器低成本的优势相结合,保证了精确的输出。同时,以一个250 W的样机验证了该变换器的特点。 The operation principle of the magnetic amplifier (Magamp) application in a novel multi-output forward-fly-back converter is analyzed at length. By outputting the high power in a forward converter and low power in a fly-back converter, this converter combines the advantage of high efficiency of the forward and the low cost of the fly-back converter, with tightly regulated outputs ensured. The characteristics of this converter are verified with the experimental results of a prototype on250 W.
