Schwarz Technische Universität Dresden Professur Grundlagen der Elektrotechnik D-01062 Dresden, Germany [email protected] ABSTRACT This work qualitatively analyzes the dynamics of a current programmed mode boost converter operating in continuous conduction mode. The analysis starts with a two-dimensional (2D) map. It proceeds via center manifold theory to a one-dimensional (1D) map. C-bifurcation analysis is applied to the 1D map. The importance of the golden mean is pointed out. This impacts on the power density spectrum (PDS) calculated by statistical analysis. 1. TWO-DIMENSIONAL MODEL Fig. 1 shows the boost converter used in this work. The load is modeled as an ideal current source . This is more adequate than a resistance load. If the active switch is closed PSfrag replacements
