A DC/DC multilevel converter for high voltage applications

Abstract

In this paper a ladder multilevel converter topology for an application of high voltage is analyzed. This converter is compared with other well-known structure called ”Flying Capacitors” showing its simplicity on the implementation and control. Furthermore, the converter is implemented and its voltage drop is tested experimentally varying the number of cells of the converter using electrolytic and polyester capacitors. The results show that the voltage drop increase quadratically with the increment of the number of cells.
