This paper derives an iterative map for the Buck-Boost converter under current-mode control. On the basis of the model, the bifurcation phenomena under variation of a range of circuit parameters including input voltage, reference current and load resistance, have been investigated. The simulation results including the strange attractors, bifurcation diagrams and waveforms are presented.
