Asymmetric Cascaded Multi-level Inverter: A Solution to Obtain High Number of Voltage Levels
Multilevel inverters produce a staircase output voltage from DC voltage sources. Requiring great number of semiconductor switches is main disadvantage of multilevel inverters. The multilevel inverters can be divided in two groups: symmetric and asymmetric converters. The asymmetric multilevel inverters provide a large number of output steps without increasing the number of DC voltage sources an...
متن کاملA Developed Asymmetric Multilevel Inverter with Lower Number of Components
In this paper, a new configuration for symmetrical and asymmetrical multilevel inverters is proposed. In asymmetric mode, different algorithms are suggested in order to determine the magnitudes of DC voltage sources. The merit of this topology to the conventional symmetric and asymmetric inverters is verified by the provided comparisons. This topology uses a lower number of power electronic dev...

متن کاملFault Strategy Analysis for Three - phase Cascaded Multi - level Inverter
This study includes a multilevel cascaded inverter along with a control strategy. This proposed control scheme directs the inverter to support the grid under three phase balanced voltage sags and during one or two phase faults. Control of voltage between grid and Distributed Generation (DG) system is a challenging subject. Integrating DG with the grid is the fundamental element of this study wh...
متن کاملOptimum Structures of a Cascaded Multilevel Inverter for Minimum Number of Power Electronic Devices
In this paper, several optimum structures of a cascaded multilevel inverter is proposed. This optimization is based on generation a constant number of output voltage levels by using minimum number of power switches or dc voltage sources or minimum amount of blocked voltage by power switches. In addition, the optimum structure for a constant number of dc voltage sources by using minimum number o...
