Abstract: This brief attempts to study the low-frequency bifurcation phenomena of a system of parallel-connected dc/dc boost converters. Analysis of the averaged state equations shows that the system loses stability via a Hopf bifurcation. The loci of eigenvalues and the local trajectories are studied. Computer simulations and experiments are performed to capture the effects of variation of some chosen parameters on the qualitative behavior of the system. In particular, it is shown that simple averaged models can be used to predict the occurrence of Hopf bifurcation in such systems.
