ABSTRACT

This paper presents the implementation of a platform capable of modifying electrical connections in order to obtain all configuration possibilities of the cascaded multilevel power converter with four H bridges in common source and single source sub-topologies in symmetrical and asymmetrical configurations, with a range of 3 to 81 voltage levels. The modifications in the number of stages, modulation and topology are performed via a visual interface in MATLAB®. The modulations are optimized through a genetic algorithm and the system control is carried out using a FPGA Virtex 5. The versatility of the platform allows one to obtain, from the hardware, the configuration of the converter and the modulation characteristics selected in the visual interface in a matter of seconds.
