Abstract

This brief attempts to study the low-frequency bifurcationphenomena of a system of parallel-connected dc/dc boost converters. Analysisof the averaged state equations shows that the system loses stability viaa Hopf bifurcation. The loci of eigenvalues and the local trajectories arestudied. Computer simulations and experiments are performed to capturethe effects of variation of some chosen parameters on the qualitative behaviorof the system. In particular, it is shown that simple averaged modelscan be used to predict the occurrence of Hopf bifurcation in such systems.
