Multilevel inverters with dodecagonal (12-sided polygon) voltage space vector structure have advantages, such as complete elimination of fifth and seventh harmonics, reduction in electromagnetic interference, reduction in device voltage ratings, reduction of switching frequency, extension of linear modulation range, etc., making it a viable option for high-power medium-voltage drives. This paper proposes...
Multilevel converters and specially multilevel four-leg four-wire converters actually are an important focus of researchers. Applications as harmonic compensation and energy quality are the major objectives of this type of converters. The balancing of the DC-Link capacitors voltage is a critical problem in multilevel converters and the first control strategy based on using the redundant vectors in...
