Abstract

This paper describes the bifurcation phenomena of a system of parallel-connected dc/dc converters. The results provide useful information for the design of stable current sharing in a democratic (central-limit control) configuration. Computer simulations are performed to capture the effects of variation of some chosen parameters on the qualitative behaviour of the system. It is found that variation of the voltage feedback gains leads to standard period-doubling bifurcation. A discrete-time map is derived and analysis is presented to establish the possibility of the bifurcation phenomena.
