Comparison of Multistage Stacked Boost Architecture Topologies in Regards of the Relation between Duty Cycle, Number of Stages and Efficiency
A step-up DC-DC converter (non-isolated) based on the current diverter principle is shown. This converter is intended for renewable energy sources or distribution networks for elevating the voltage from LV to MV levels. The relationship of stage number, duty cycle and efficiency is analyzed. In addition first measurement results with a lowvoltage prototype are shown.
