Proliferation of the voltage-sensitive loads in the distribution systems has made the voltage quality an important issue. The main factors considering the voltage quality are the voltage sags and voltage swells. There are many available solutions to improve voltage quality. In the past years, application of the power-electronic based devices known as custom power devices have developed an interesting...
In this paper a new structure for asymmetric multilevel converters is presented. The new topology is consisting of N series-connected of two interconnected multilevel converters per phase. The presented circuit is an optimized multilevel converter with minimum DC voltage sources and switches. The investigated topology can generate a large number of levels (odd and even) without increasing the number...
