Abstract

Based on a generalized state-space sampled data modeling, an iterative and efficient algorithm for deriving the small signal transfer functions of any DC-DC power converter is proposed. This algorithm is suitable to be implemented in a software program as an analytical tool for automated control analysis of general DC-DC power 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 power converters and control methods
