Voltage Step-Up Converter based on Multistage Stacked Boost Architecture (MSBA)

A non-isolated DC-DC converter is presented, based on the current diverter principle. The converter is foreseen for larger photovoltaic plants or other DC collection networks for renewable energy sources. The topology allows the DC-DC conversion as step-up converter typically from LV to MV levels. The Multistage Stacked Boost Architecture allows a conversion to voltage levels higher than the blocking capability of the used semiconductor devices.
