The analysis of DC-DC converter topologies based on stackable voltage elements

In this paper, a method for generating non-isolated dc/dc converter topologies is summarized. This method utilizes the stackable voltage stiff elements in a dc/dc converter and arranges them to create new usable voltage levels. By defining the input and output for different voltage stiff elements, a comprehensive set of converters can be created. The canonical first order switching cell, along with a proposed third order switching cell, are used to help analyze the first and third order converter topologies. Detailed analysis is provided using the two switching cells. Finally, transformer-less multiple-inputs converters are also analyzed using both the two switching cells and the stackable voltage element concept.
