Abstract

This paper studies the bifurcation behaviour of a system of coupled buck converters under current-mode control. The effects due to the variation of the reference current are studied. It has been observed that the system exhibits low-frequency bifurcation behaviour while period-doubling at switching frequency is suppressed. Extensive simulations are used to capture the findings. Time-domain waveforms, stroboscopic maps and trajectories are shown. The results show the drastic alteration of bifurcation behavior of dc/dc converter systems due to subtle coupling.
