Summary:
Interleaved boost converters are useful in renewable energy applications like photovoltaics (PV) and fuel cells (FC). In this paper we investigate the nonlinear behavior of an interleaved boost converter fed from a PV source. In this system, at a critical parameter value the normal periodic orbit loses stability through a Neimark-Sacker bifurcation and a torus is created. We demonstrate that the torus undergoes folding when it hits one of the switching borders and is deformed when it grazes another border. Finally we observe that when the converter is fed by PV the system tends to be less stable.
