Binary tree structure modeling method of DC/DC power converters

This paper illustrates a general modeling method for dc/dc power converters, which is termed averaging binary tree structure models. The proposed method, based on the switching signal flow graph (SSFG) models, can describe the converters as a binary tree structure. The general construction principles of the binary tree for the complex flow graph system are summarized and developed. The proposed method has been applied to the modeling for 2/sup nd/ order dc/dc converters, which shows the advantages of high convenience and practicability without the tedious analysis caused by Mason's rules or graph reduction techniques, compared with the conventional SSFG modeling. Experimental observations are provided to validate the proposed algorithm.
