In this paper, an automated averaging modeling methodology is set forth applicable to power electronic converters of arbitrary complexity. The user-defined inputs consist of a circuit description similar to the SPICE netlist (network graph and branch parameters), whereupon the input/output impedance-versus-frequency characteristics are automatically and rapidly generated. In addition to eliminating the need for the analytical derivation of average-value models, this methodology readily permits the inclusion of secondary effects such as conduction losses, switching losses, and magnetic nonlinearities, to name a few. This methodology has been successfully applied to characterize the impedance of a one-quadrant dc/dc buck converter, a three-phase diode rectifier source with three different modes of operation, and a space-vector-modulated dc/ac inverter.
