Intermittency in switching power converters: Theoretical analysis

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.
