Recently much attention has been paid to investigation of nonlinear dynamics of switching power converters, as this kind of dynamical system, being inherently hybrid, is capable of exhibiting a wide variety of well known smooth as well as novel non-smooth phenomena. This research shows the diversity of complex interactions of smooth bifurcations and border collisions in one of the most typical power circuits – boost converter under current mode control – applying the method of complete bifurcation groups. The effects of realistic parameters and implementation of compensation signals on the robustness of chaotic modes of operation are investigated and explained in details.
