摘要

This study presents a procedure for modelling of switching converters with reduced redundant power processing (R2P2). This class of converters consists of two basic DC-DC switching converters connected in non-cascading structure. The proposed procedure uses signal flow graphs on converters with R2P2, according to currents and voltages relationship of each non-cascading structure. In the beginning, the procedure does not require specific knowledge of the basic converters being used, but only the structure of the converter with R2P2. The corresponding basic converters are incorporated later. Although the procedure is applied to converters with R2P2, it can also be applied to other configurations that are based on the interconnection of two converters. The resulting models are validated using simulations and experimental results.
