In view of reasonable explanation of intermittent subharmonics and chaos that can be gained from coupling filter between circuits, this paper discusses a method that maps time bifurcation with 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. In this paper, 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. Thus, it is proved theoretically that the intermittency in switching power converter can be explained in terms of coupling of spurious interference.
