Piecewise-smooth model for bifurcation analysis of a three-phase controlled rectifier in regeneration mode

Power conversion systems with transistor controlled rectifiers are widely used in modern machinery. Currently, the actual mathematical description of such systems is not sufficiently elaborated, that complicates their research and development. This paper represents the piecewise-smooth mathematical model of a three-phase controlled rectifier in regeneration mode. The results of bifurcation processes simulation implemented by means of the proposed model are demonstrated. They prove its applicability to study of nonlinear dynamics of the considered converter.
