An automated algorithm for small signal analysis of dc-dc power converters

Based on a generalized state-space sampled data modeling, an iterative and efficient algorithm for deriving the small signal transfer functions of any de-de converter is proposed, This algorithm is suitable to be implemented in a software ,program as an analytical tool for automated control analysis of general de-de converters, Such a tool would reduce considerably the time needed by research engineers in modeling existing and new topologies and control methods, The algorithm proposed is applicable to different kinds of linear and nonlinear control methods. It has been verified on different converters and control methods.
