Abstract: This paper presents two series of models in the buck-boost converters with input regulators under peak current mode control. Stroboscopic maps are derived to describe the dynamical behaviors of buck-boost converters with input filter capacitor. In terms of the developed discrete maps, fast scale instabilities in buck-boost converters are studied. Numerical results reveal the circuit system exhibits distinguishing nonlinear phenomena, i.e., intermittent bifurcations and chaos. In addition, the periodicity of the intermittent behaviors is also analyzed in detail.
