LOPEZ-CANON, Andrés Mauricio; DIEZ-MEDINA, Rafael Fernando; PERILLA-GALINDO, Gabriel  and  PATINO-GUEVARA, Diego Alejandro. High Voltage DC/DC Multilevel Converter in Ladder Topology. Ing. Univ. [online]. 2012, vol.16, n.1, pp.117-133. ISSN 0123-2126.

This article analyzes and designs a ladder multilevel converter topology for a high voltage application (3000 V). This converter is compared to other well-known structures called Flying Capacitors showing its simplicity for implementation and control. In addition, an analysis of the voltage drop of the ladder topology is carried out as a function of the number of cells and of the load current. Furthermore, the converter is implemented and successfully achieves 3000 V 100 mA. The theoretical analysis is validated by the results. The converter is tested with two different types of capacitors in order to determine which one offers a better performance.

Keywords : Power electronics; semiconductors; DC/DC converter; electric current converters.
