Active Thermal Control in Neutral-Point-Clamped Multilevel Converters Based on Switching-Cell Arrays

Neutral-point-clamped multilevel converters are a suitable solution to the implementation of low–medium voltage and power applications at present, thanks to their intrinsic superior voltage and current quality. The conventional configurations of these converters present uneven power loss distributio...
