摘　　要：用两种与传统不同的电路模型表征正激变换器.其一用LC串联谐振实现磁复位功能(这一模型中没有磁复位绕组,并确认开关管存在与其并联的电容).其二主要用磁复位绕组实现磁复位功能(这一模型中有磁复位绕组,但也确认开关管存在与其并联的电容).用相平面分析法分析这些模型,得到了正激变换器运行时电路和磁路特征参量的解析表达式.本文的分析和解析结果以及后续对这两种正激变换器的全面分析被称为"新建正激变换器运行理论".Forward converters are characterized by two models different from the traditional model.One of them is that the magnetic reset function is realized by using LC series resonance.In this model there is no magnetic reset winding,a capacitor paralleled with the switching device exists.The other is that the magnetic reset function is mainly realized by using the reset winding.In this model there is the magnetic recycle winding,the capacitor paralleled with the switching device exists too both models are analyzed.By means of the phase plane analysis method,a lot of analytical expressions of parameters of both electric circuits and magnetic circuits when forward converters are operating.These analyses and results here and followed papers are called ＂newly established operational theory of forward converters＂.
