A nonlinear approach to the analysis of stability and dynamics of standalone and parallel DC-DC converters

The authors analyze the stability and dynamics of two different types of power electronic converters. Using results based on bifurcation analyses, they describe the dynamics of these nonlinear systems beyond the linear regime and demarcate their stability boundaries. Their results show the shortcomings of traditional methods based on averaging and pave the way for less conservative control design, improved electromagnetic compatibility and newer applications.
