The existence of period-doubling bifurcation cascades and chaos in DC drives with full-bridge converter is well known. This paper reports for the first time the occurrence of coexisting attractors with a fractal basin of attraction in this relatively simple deterministic system. At some parameter values the trajectories converge on either a period-1 or a period-3 attracting set depending on the initial...
Fast-scale instabilities in full-bridge converter dc drives are analysed in this paper using Filippov's method of differential inclusions. This method is very suitable for stability analysis of systems with switching nonlinearities and has been successfully applied to mechanical switching systems and dc-dc converter circuits. This paper presents the first application of the method in a variable speed...
