This paper studies the effect of interleaving operation on the bifurcation behaviour in a system of parallel-connected dc/dc buck converters. Sim ulations and analysis are preseted for both the cases of interleaving operation and synchr onous operation. It is found that v ariation of the v oltage feedbac k gains leads to perioddoubling bifurcation. Interleaving operation will discourage the occurrence of this bifurcation by widening the stable region. Also, variation of output capacitance, load or switching period leads to Neimark-Sacker bifurcation. Interleaving operation will male this bifurcation more likely to occur by narrowing the stable region. Bifurcation boundaries of stable period-1 operation in the two cases are located and compared.
