Comparative Analysis of Input-Series-Output-Series Partial Power Rated DC to DC Converters

This paper analyses the possibilities of the input-series-output-series partial power converter configuration with auxiliary series resonant balancer converter. In comparison to the standard converter topologies, the differences between processed powers, as well as differences between powers processed by the inductors are presented in boost, buck and buck-boost cases. Additionally, in the case of the boost topologies, the more in-depth analysis of the power losses is shown. Consequently, the benefits regarding the converter efficiency of the input-series-output-series boost partial power rated converted are discussed.
