Bifurcation behaviour in parallel-connected boost converters

This paper describes the bifurcation phenomena of a system of parallel-connected d.c./d.c. boost converters. The results provide important information for the design of stable current sharing in a master-slave configuration. Computer simulations and experiments are performed to capture the effects of variation of some chosen parameters on the qualitative behaviour of the system. In particular, it is found that variation of some parameters leads to Neimark-Sacker bifurcation. Analysis is presented to establish the possibility of the bifurcation phenomena.
