A symbolic computation package for averaged analysis of power electronic systems

A symbolic computation package for averaged modeling and analysis of switching power converters is presented. Starting from a netlist describing the topology of a converter, the package first generates the state-space models of the converter in different switch configurations. A general averaging method is then applied and an averaged model is automatically generated. The package is applicable to converters using different switching techniques, including hard switching, quasi-resonant soft switching, and soft transition.
