Abstract

This paper proposed a high voltage conversion ratio cascade boost converter topology composed two stages of converters. First stage boosts the input source voltage twice larger by using the double-mode switched-capacitor cells converter (SCC). Second stage provides a high voltage conversion ratio boost converter with a couple inductor and diode-capacitor (DC) snubber. The converter topology analysis and design are described in detail. Results of simulation and experimental measurements are carried out to verify the performances of the proposed high voltage conversion ratio cascade boost converter under different operation conduction modes.
