Steady state analysis for an arbitrary number of ZVS PSM FB converters in an Input-Parallel Output-Series configuration

Abstract

The Zero Voltage Phase Shift Modulated Full Bridge has been quite used for the high frequency isolated dc-dc stage of dc charging stations for electric vehicles. Figuring out how to manage high power in only one dc-dc converter is a challenging task and to solve this, the present paper uses Input-Parallel Output-Series association of theses converters. The main goal will be to present a steady state analysis that can be widely employed to characterize this topology with an arbitrary number of converters, turning the process of designing easier and failproof.
