摘要
详细分析了一种运用了后级调整技术的新颖的多路输出正反激变流器的工作原理。该变流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,该电路将正激变流器的高效率和反激变流器的低成本的优势相结合,同时后级调整技术还保证了每个绕组的精确输出。一个250W的样机验证了该变流器的特点。
A novel multi-output forward-flyback converter with secondary side post regulation is proposed. This converter can output the high power in forward converter, and low power in flyback converter. So it combines the advantages of high efficiency of forward and the low cost of flyback and also has tightly regulated outputs. The operation principle of the converter is discussed, and verified on an experimental prototype on 250W.
