摘要
鉴于间歇分谐波与间歇混沌的产生可以从电路耦合滤波的角度进行合理的解释 ,则可以此为基础 ,用参数域上的分叉来映射时间域上的分叉 ,从而使得可以用一般的特征值分析方法 (针对参数分叉 )来实现变换器中间歇现象的分析 (针对时间分叉 ) ,特征值、分叉图及最大Lyapunov指数均表明得到的研究结果与仿真及实验是完全一致的 。
In view of that reasonable explanation of intermittent subharmonics and chaos can be gained from coupling filter between circuits, this paper will produce a method that maps the time-bifurcation with the parameter-bifurcation. Based on this mapping method, the general analysis method of characteristic multiplier, which is originally aimed at parameter-bifurcation, can be used for the study of intermittency, i.e. time-bifurcation. All researches coming from characteristic multipliers, parameter-bifurcation diagrams and the largest Lyapunov exponent indicate the same results as those produced by simulation and experiment. So it is proved theoretically that the intermittency in switching power converter can be explained in terms of coupling of spurious signals.
