Voltage balancing circuit for modular step-down DC/DC converter

Abstract

In this paper, a modular auxiliary DC/DC converter, based on super-capacitor voltage balancing topology is presented. The converter is able to supply from voltage gate drive units of high voltage converter switching units. Further, the theoretical basics of this converter are analyzed as well as simulation of topology is observed. Finally, an experimental evaluation of 300V, 50W converter prototype is presented.
